Semper Fi Heating and Cooling Honors Veterans with Memorial Day Giveaway

Peoria, AZ – May 24, 2023 – Semper Fi Heating and Cooling, a leading HVAC company dedicated to serving the community, is proud to announce a special Memorial Day giveaway. As a gesture of gratitude and support for our veterans, Semper Fi Heating and Cooling will be providing a free HVAC unit to a deserving veteran residing in Peoria, AZ.

This year’s recipient, a Peoria resident who wishes to remain anonymous, has a remarkable story of resilience and courage. Despite battling multiple medical conditions, this veteran exemplifies unwavering determination and a sharp mind. Having received a quote for the repair of his central AC unit, he was disheartened by the exorbitant cost, exceeding his limited means.

To cope with the scorching Arizona heat, the veteran resorted to using a window A/C unit, which only provides partial relief in one room. Consequently, he spends his days enduring the discomfort, wearing minimal clothing in an attempt to stay cool. Living on a meager fixed income and receiving limited food stamp assistance, he faces numerous financial challenges.

Compounding his difficulties, the veteran was forced to sell his car to cover a substantial increase in his monthly space rent for his mobile home. Consequently, he now finds himself confined to his overheated residence, lacking transportation and the support of local friends and family.

The veteran’s journey is marked by resilience and an indomitable spirit. Having grown up in the South during a time of segregation, he carries the weight of painful memories and experiences. Despite these hardships, he remains determined to improve his circumstances and has sought assistance with obtaining his birth certificate, an essential step towards accessing additional government support for his rent.

Semper Fi Heating and Cooling is deeply moved by this veteran’s story and is committed to making a positive impact in his life. Understanding the importance of a comfortable living environment, especially during the scorching Arizona summers, Semper Fi Heating and Cooling will install a brand-new HVAC unit in the veteran’s mobile home at no cost.

“Memorial Day is a time to honor and remember the sacrifices made by our veterans, and Semper Fi Heating and Cooling is proud to show our appreciation by giving back to those who have served our country,” said Jesse Keenan, CEO of Semper Fi Heating and Cooling. “We hope that this gesture will provide comfort and relief to the veteran, making his daily life more manageable and enjoyable.”

Semper Fi Heating and Cooling has a long-standing commitment to community service and supporting those in need. Through this Memorial Day giveaway, the company aims to demonstrate its unwavering dedication to veterans, recognizing their contributions and the challenges they may face.

Heating & Cooling Terms You Should Know – Part 1

At some point in a conversation between a homeowner and an HVAC service technician, a word or acronym may come up that is unfamiliar to the homeowner or is being used in an HVAC-only context. The following is a glossary of phrases, words and acronyms that may be helpful to know.

  1. Air Handler is the part of a ventilation system that draws in cool or warm air for a furnace or air conditioner to turn it into warm or cool air, respectively, and then blows it into ducts that deliver it throughout a home.
  2. BTU/BTUh is short for British Thermal Unit. One unit is the amount of heating needed to raise one pound of water by one degree Fahrenheit. The higher the BTUs, the greater the heating capacity of a furnace. BTUh refers to British Thermal Units per hour.
  3. Carbon Monoxide (CO) is a byproduct of burning gas that can cause serious health problems. You won’t see, smell or taste it because it is colorless, odorless and tasteless. Not much CO is produced by a gas furnace, but if the air vents are not clear, you may have CO poisoning problems. Don’t rely on carbon monoxide detectors in your home; have your furnace checked by qualified technicians regularly.
  4. CFM (Cubic Feet per Minute) is the measurement of how much heated or cooled air is circulating when a furnace or air conditioner is operating. A qualified HVAC technician can calculate the optimal CFM based on the size and construction of your home. An optimally sized system will keep your home comfortable and energy efficient.
  5. Condenser is the outside part of an air conditioner. The outside condenser cabinet contains the compressor coil that serves to discharge heat outside and move cool refrigerant indoors.
  6. Compressor is part of the condenser unit of a heat pump or air conditioner. The compressor circulates refrigerant between the indoor and outdoor units, absorbing heat indoors, discharging it outdoors, and moving cool refrigerant back indoors.
  7. Ductwork is a system of metal ducts or synthetic tubes that, depending on the season, move warm or cool throughout your home. To keep a furnace and air conditioner operating properly and efficiently, it is important to keep ducts clean and not obstructed.
  8. Energy Efficiency Ratio (EER)/Seasonal Energy Efficient Ratio (SEER) are ratios that measure the cooling energy provided relative to the electrical energy used. EER provides for the highest temperature of the year while SEER calculates relative to the seasonal average. The higher the EER/SEER, the more efficient the system.
  9. Energy Star is a program from the Environmental Protection Agency to help homeowners pick the most energy-efficient HVAC systems and other major home electrical appliances. An Energy Star system indicates that the system meets or exceeds federal guidelines for energy efficiency. Energy Star-rated HVAC systems can be 40% to 50% more efficient than older non-Energy Star systems.
  10. Heat Pumps are a highly efficient alternative to conventional central heating and air conditioning systems. They work by moving heat. In summer, they remove heat from inside and discharge it outside. In winter, they draw heat from outside and circulate it inside. Contrary to common logic, there is plenty of heat outside on even the coldest days.

Ventilation: All About the V in HVAC

You’ve seen the acronym HVAC, pronounced H-Vac, and you know it somehow relates to the heating and cooling system in your home. The H is for Heating and the AC is for Air Conditioning. Right in the middle is V for Ventilation. Your central ventilation system consists of ductwork that runs to the far corners of your home and the blower fans and motors that circulate warm or cool air.

Your heater and your air conditioner take a rest for part of the year, but your ventilation systems seldom gets a day off. Ventilation is the unsung and underappreciated hero of your HVAC system. Furnaces heat, air conditioners cool, and ventilation systems collect and deliver warm or cool air to keep your home comfortable year-round.

Your ventilation system doesn’t need much attention, but occasionally air ducts need to be cleaned. You have filters that need to be changed frequently to remove pollutants that are circulating in the air you breathe. But over time, dirt builds up inside the ducts and needs to be removed. The before and after pictures say it all.

Where does all of this dirt come from? If dust collects on your furniture, it circulates through your ventilation system. The dust that your home vacuum collects is dust that has made its way through your ductwork. Pet dander, smoking, water damage, remodeling construction, dirty shoes and dirty clothes all contribute to dirty ducts.

If you change your filters regularly, you can ignore your ducts and the rest of your ventilation system for a few years, but dirt will accumulate inside your ducts and the air you breathe will become unhealthy. Eliminating the dust, dirt, mold and other pollutants from your ductwork will improve indoor air quality, keep your home cleaner, and make your entire HVAC system more efficient. Your home air quality will substantially improve with professional duct cleaning.

Semper Fi Heating & Cooling has the experience and equipment to clean your ductwork and improve the quality of the home air that you breathe. Duct cleaning is a job for trained professionals. An inadequate vacuum system can release more contaminants than if you had left the ducts alone. Don’t expect immediate changes in your personal health, but do expect your home to be cleaner. A proper duct cleaning job will significantly reduce the dirt and contaminants in your home air.

What you should expect from the duct cleaning process:

  • Before you start vacuuming, your system should be checked for asbestos-containing materials. Asbestos requires specialized procedures and should not be disturbed or removed except by specially trained and equipped contractors.
  • Only equipment that exhausts particles outside the home or through HEPA filters should be used.
  • The inside of ducts should be carefully brushed in conjunction with vacuuming.

There are steps you can take to reduce future buildup of dirt in your ductwork:

  • Use high-efficiency furnace filters and change them frequently. If filters get clogged, change them even more frequently.
  • When your unit is serviced, make sure that the cooling coils and drain pan are also cleaned.
  • Remove dirt and dust from your home regularly, and use high-efficiency filters in your vacuum.

Duct cleaning will improve your indoor air quality, but cleaning is not the only issue related to ducts. By most estimates, as much as 30% of the air that goes into your ducts leaks out before being delivered to wherever the ducts lead. While getting your ducts cleaned, consider taking the next step and get them professionally sealed. You can look for leaks and slap a piece of duct tape over the gap, but that is not professionally sealing your ducts. You won’t eliminate the majority of leaks unless you have the right equipment to find the leaks and the right materials to seal them up.

Call the professional technicians at Semper Fi to learn more about duct cleaning, and check the website for special pricing.

Good Air Flow for a Healthy and Clean Home

Adequate and clean air flow is critical for the proper operation of your heating and air conditioning system. Without good air flow, your equipment will wear out quicker and your utility bills will be higher. The health of your family is at risk and the overall comfort of your home is reduced.

Clean Your Air Filter Regularly

The first step in keeping home air clean is to replace your air filter frequently. The general guideline is to replace the filter at least every three months. You may find that even more frequent replacement is needed; no two homes are the same. If your home air smells musty, change the filter. If your furniture gets dusty quickly after cleaning, it is probably time to change the filter. If your furnace is running more often and longer than you think it should, it might be an indication that filters need to be changed.

Filters should be replaced with the change of seasons. Switching from heating to air conditioning or from air conditioning to heating is a good time to change filters. For central Arizona, Semper Fi recommends a non-pleated, fiberglass filter. Minimum Efficiency Reporting Value (MERV) is the measurement system for a filter’s effectiveness in reducing airborne particles and contaminants. The higher the number from 1-20, the more effective the filter. However, the higher the number, the more the filter will restrict air flow. To determine the right MERV for your HVAC system, you should find the recommended maximum for your system and use a filter that is just below the maximum.

Fortify Your Air Filter With a REME HALO Systems

Air filters are important, but filters alone cannot remove mold, pollen spores, bacteria, mildew and odors. Semper Fi Heating & Cooling recommends installing the REME HALO, which uses reflective electromagnetic energy to produce hydrogen peroxide plasma that passes through your air handler and circulates through your whole house. Hydrogen peroxide occurs naturally. It is part of the process of purifying the clean, outdoor air that we breathe. The hydrogen peroxide produced by REME HALO continues to eliminate pollutants on surfaces in your home, even when the blower on your HVAC system is not running.

A REME HALO system partners with your filtration system to capture the pollutants that are circulating in your home air. It also kills and eliminates the pollutants before they circulate. It works with your filtration system by causing particle pollutants to solidify and stick together, making them larger and easier for your filter to catch. That is another reason to change your filter often.

Mold, pollen spores, bacteria, odors, and other dangerous pollutants can also be removed with UV-C light installed in your duct system. Ultraviolet light in wavelengths between 200 and 300 nanometers are proven to destroy harmful microorganisms by altering their DNA and removing their ability to replicate.

REME HALO and UV-C lighting are both proven to be effective and can be installed quickly by the professionals at Semper Fi. They come with a five-year warranty. It is recommended that the hydrogen peroxide-producing cell be replaced every two years. Call the professional HVAC technicians at Semper Fi today to learn more about how clean air flow along with air purification can reduce the pollutants in the air that is circulating in your home. Purified air circulation will help keep your family healthy and safe.

Having Furnace Issues?

Furnace Repair and Maintenance

With proper furnace maintenance and occasional tune-ups, furnaces usually have a long and dependable life. And while things can go wrong, most can be fixed.

By the time a furnace needs to be replaced, high-efficiency improvements have been made in newer systems, and reduced utility costs will at least partially offset the cost of a new furnace. There are several signs that a furnace needs repair.

Pilot Light Issues

The pilot light should burn with a blue flame. If the flame is yellow or orange, there may be a carbon monoxide problem. Turn off your furnace and call a service technician. Carbon monoxide in your home can cause serious health issues, so don’t delay in getting the problem repaired. If the pilot light flame is burning blue but flickering, that could be a different problem. Most likely, the gas supply line is partially clogged and needs to be cleaned.

Heat Exchanger Problems

The heat exchanger is the part of a furnace that separates the air that a furnace circulates throughout a home from the hazardous gases in the air that have been heated in the combustion assembly. The air you breathe moves through tubes that pass through the combustion chamber. The harmful gases get exhausted from the chimney or vent, and the clean, heated air circulates around the home.

The most common problem with the heat exchanger is that after repeated expanding and contracting from heating and cooling, metal fatigue causes cracks or holes in the tubes. That allows the dangerous gases to mix with the warm air that circulates in the home. A service technician can check your furnace for a cracked heat exchanger.

Thermostat Problems

If the thermostat display is blank, check the batteries. If replacing batteries does not solve the problem, check the breaker box. If the breaker is not thrown, it may be time for a thermostat replacement. If the furnace is running continuously and not shutting off, try setting it to auto and then try it at different temperature settings. If it still runs continuously, the thermostat may need to be replaced.

Limit Switch

The limit switch senses the temperature of the furnace and turns the furnace off and on during the normal heating cycle. It is usually very dependable, but occasionally it fails and will prevent the furnace and blower to turn off or on. The limit switch also has a high temperature limit that will shut off the heating burners and leave the blower working so that the heat exchanger does not overheat. Replacing the limit switch is a relatively inexpensive operation.

Cacophony of Rackets

Different noises indicate different types of problems with your furnace, and most of them need attention. A squealing noise is likely to be caused by a fan belt problem. There is an electric motor in a furnace that uses a fan belt to turn a fan that blows warm air through ductwork and into your home. If the belt is worn and damaged, it may slip and make a squealing noise. Turn off your furnace and have the belt replaced. A scraping sound is probably the result of worn bearings somewhere in the power assembly. Turn off your furnace and get the problem fixed to avoid additional damage.

Do you hear bangs and clangs in your ductwork when your furnace starts up and the warm air starts blowing? That is the result of cold ductwork expanding from the heat, not an operational problem that will cause damage. You may want to make sure the ducts and joints are adequately attached and secured.

Little or No Warm Air

If the amount of warm air is reduced, check to see if the air filter is dirty or clogged. Change the filter often. If clean air cannot get in the cold air vents and through the filter, warm air will not come out. If the full heating flame is burning and no warm air is moving through the ducts, there is a circulation fan problem. The cause is most likely a worn-out or broken fan belt. The motor and fan itself have other moving parts that can fail.

Some furnace problems are more urgent than others. Some problems are dangerous to the health of homeowners, and others need attention to avoid additional harm. All furnace problems need attention to keep your home comfortable and safe.

Beyond the Filters – Home Air Purification Options

Conditional air filters do a great job with most particulate pollution. Unfortunately, in the extreme heat of Arizona, high-efficiency filters can starve an HVAC system of the airflow it needs to provide maximum indoor home comfort. For home comfort optimization during peak heat during Arizona summers, Semper Fi recommends a non-pleated, fiberglass filter. For customers with indoor air quality concerns, there are additional options for the homeowner in need of hospital-quality air purification without the use of high-efficiency, pleated filters that can restrict airflow.

Bipolar Ionization

Bipolar Ionization splits molecules in the air, including water vapor, into positively and negatively charged ions. The opposite charges attract each other to form a compound. The positive and negative ions surround air particles, and the added mass causes the air particles to be captured by an air filter and removed from the air. The positive and negative ions also surround and pull hydrogen away from pathogens like viruses, bacteria, and mold spores. With the hydrogen pulled away from the protein coat, the virus cannot infect. With bacterium or mold, when the essential hydrogen is removed, the cell is ripped open and the pathogen dies, preventing infection.

Electrostatic Air Filters

Electrostatic Air Filters are most often used to remove dust, dander, mold, or pollen from an indoor space. Along with regular cleaning and adequate ventilation, an electric air cleaner installed into your HVAC system can help make your home more allergen-free. Electrostatic filters are magnets for dust. Like the positive and negative sides of a magnet that attract each other, the particles passing through a filter are given an electrical charge before they pass plates in the filter where they are attracted to the opposite charge. Under ideal conditions, the pollen and other allergens floating in your home air get stuck to the plates and are removed from the air circulating in your home.

However, everyday conditions are not ideal. The electrostatic filters need to be cleaned regularly. More importantly, continuous use of electrostatic filtration will raise the level of ozone in a home and cause other problems for anyone who suffers from allergies.

There is another solution. Allergy filters that come with an electrostatic charge will attract and hold dust, dander, mold, and pollen. These filters are flat rather than the more common pleated filters. They are also less expensive than high MERV-rated HEPA filters. The drawback is that eventually they will reach their load capacity and need to be changed. Unlike pleated filters, they can be washed and reused.

Ultraviolet Light Air Purification

Ultraviolet Light Air Purification is a viable alternative for scrubbing viruses and other pathogens from home air. UV light is the shortest wavelength light; you know it as the part of sunlight that causes sunburn. With home air purification, you are not directly exposed to the UV light; it is installed in your ventilation duct system, downstream of a high-quality air filter.

After a day at the beach, you will likely experience radiation burns resulting in redness of your skin. The redness is a direct result of damage to your skin from UV radiation. In moderate quantities, it is relatively harmless. Extreme exposure can cause skin cancer. Unlike our skin, bacteria are sensitive to even small amounts of UV exposure. They are harmless after effective exposure to germicidal ultraviolet light.

For a whole home installation, the UV lights will be installed inside ductwork and will not be directly exposed to you. The bulbs in UV lights generally need to be changed once a year but vary by manufacturer.

Semper Fi Heating & Cooling can help you choose from these and other home air purification systems to find the system that is right for your family.

Does My Air Conditioner Need Freon? What is Freon?

Let’s Start with Definitions

Just to be a stickler for language and definitions, let’s offer two definitions directly from Wikipedia:

      1. Freon is a registered trademark of The Chemours Company, which uses it for a number of halocarbon products. They are stable, nonflammable, low-toxicity gases or liquids which have generally been used as refrigerants and as aerosol propellants. These include the chlorofluorocarbons (CFCs) that cause ozone depletion. Freon is a brand name for the refrigerants R-12, R-13B1, R-22, R401A, R502, and R-503


    1. manufactured by The Chemours Company.
    1. The term “freon” is also a generic descriptor of a fluorocarbon refrigerant.

To put it another way, Freon is a brand name and a registered trademark of a refrigerant widely used in air conditioning systems. CFCs are a component of that refrigerant that has been banned as a cause of ozone depletion. The word freon lives on as a generic word for any refrigerant used in air conditioners.

Specifically, the CFC R-22 is banned from manufacturing or importing into the United States. But there are many air conditioning systems still operating with Freon R-22. Freon R-22 has become in increasingly short supply and as a result the price has increased significantly. Typically Freon R-22 is 300-400% more expensive than the current standard Freon 410A. Newer systems have not been using Freon R-22 for a decade.

Should Older Systems that Use R-22 Be Replaced?

If your system uses R-22, then it is older and possibly nearing the end of efficient operational life. It may still have some useful years, and if it continues to perform well there is not an immediate rush to replace it. You should, however, get regular maintenance and keep your older system operating until it becomes time for a replacement.

In the normal course of operation, an air conditioning system can lose a small amount of Freon every year. During your semi-annual maintenance visit, it is not uncommon for your HVAC technician to recommend a “top-up” of the refrigerant levels on your system. The challenge occurs if there is a significant refrigerant leak in a Freon R-22 system. In this instance, even if the leak in the system can be repaired, it will most likely be cost-prohibitive to recharge (i.e. refill) the system with Freon R-22 and thus a system replacement is most commonly the best course of action at that time. Remember, in this instance it is not that Freon R-22 is not available, but that it is so expensive that investing several thousand dollars in additional Freon R-22 does not make financial sense for homeowners.

The service technicians at Semper Fi can help you understand your options with regard to freon availability. We are here to help you get as much life out of your older system as practically possible and offer competitive, cost-effective system replacement options as needed.

What Does Freon Do in Your Air Conditioning System?

Freon passes through your AC refrigerant lines. The air conditioner compressor compresses freon gas which makes it hot. It then travels through coils that cool and convert it from gas to a liquid state. Next, it travels to evaporators that convert it back to gas that can cool the air in your home.

After years of circulating, the amount of freon in your system will decline. Tiny pinhole leaks will allow freon to escape and make the pressure in the system decline. When people refer to an AC system needing to be recharged or refilled, they are referring to the levels of freon. If your system is running longer than it did in the past, or if it seems that your system is not keeping you as cool as you expect, it could be that the freon needs to be recharged.
Call Semper Fi to make an appointment for a technician to check your system’s freon levels and add whatever is needed to get your system back to working like new at full efficiency.

Honor Veterans on Veterans Day

Semper Fi Heating & Cooling is a veteran-owned company that extends 20% discounts to veterans and their families. As a company, Semper Fi Heating & Cooling considers Veterans Day to be a sacred time to proudly honor those who have served.

World War I did not officially end until the signing of the Treaty of Versailles on June 28, 1919, but seven months earlier on the 11th day of the 11th month at the 11th hour, an armistice was signed to end the fighting between the Allied Nations and Germany in what was then called “the war to end all wars.”

In November 1919, President Woodrow Wilson proclaimed November 11 as the first commemoration of Armistice Day when he said, “To us in America, the reflections of Armistice Day will be filled with solemn pride in the heroism of those who died in the country’s service and with gratitude for the victory, both because of the thing from which it has freed us and because of the opportunity it has given America to show her sympathy with peace and justice in the councils of the nations.”

In 1954 a law was passed to amend the law that created Armistice Date by changing the name to Veterans Day so that November 11 became a day to honor American veterans of all wars. Veterans Day is an official government holiday; government offices along with many schools are closed. In many places in the U.S., the day is marked by parades and church services, the flag is hung at half mast, and a period of silence lasting two minutes may be held at 11:00 AM.

Veterans Day is focused on honoring and showing pride in veterans who still live among us. Memorial Day is a day to honor those who gave their lives while serving in the military. Arlington National Cemetery holds memorial services on both Veterans Day and Memorial Day. According to the Department of Veterans Affairs, as of 2020 there are 325,574 living American veterans who served in World War II. There are about 500,000 Korean War vets, 610,000 Vietnam War vets, and 2.5 million post-9/11 vets who served in Kuwait, Iraq and Afghanistan. Eighty-three percent of vets are male, and 17% are female.

Life is not easy for many veterans. Eighty percent of them spent time in overseas combat zones. Sixty percent are under the age of 34. Twenty-two veterans commit suicide daily. Thirty percent have disabilities as a result of their service. As many as 20% of veterans have been diagnosed with post-traumatic stress disorder. Twenty-two percent are diagnosed with depressive disorder. Only one-third of vets that need mental health care have sought treatment. The vast majority of veterans joined the military to serve our country and nearly all of them are proud of their service.

Our veterans need your support and understanding. Many of them feel that the rest of America does not understand or doesn’t even think about the trauma they have experienced. Be thoughtful and be kind to vets; they will appreciate our support.

Air Purification with UV-C Light

Air Purification with UV-C Light

Airborne pollutants like viruses, bacteria and mold are found in most homes. Modern construction standards and insulation do a great job sealing entire homes to improve heating and cooling efficiency. The downside of a well-sealed home is that moisture is prevented from escaping, which allows for the growth of harmful germs that cause a variety of illnesses.

Portable air purification devices help, but if you’re serious about removing harmful pollutants from your home, you need a whole home system that delivers purified air through your central heating and air conditioning system. You need to destroy bacteria and viruses on surfaces and in the air, making your whole home a safe haven for the health of you and your family.

HEPA air filters are great and it is highly recommended that you use them. They play an important role in removing larger dust and mold particles. However, air filters alone will not remove the smaller and more dangerous pollutants. There are other whole home technologies, but UV-C light, properly located in your central air distribution system, has clearly emerged as the best option for whole home air purification systems. Among UV-C systems, REME HALO is the leader for whole home air purification.

What Does REME HALO Do?

REME HALO uses patented REME Cell technology with UV-C light to create low-level, airborne hydrogen peroxide throughout an air-conditioned space. Not only does it kill bacteria and viruses, it reduces allergens, mold, microbials, smoke, odors and volatile organic compounds (VOCs). REME HALO utilizes patented and third-party tested and validated technology to eliminate 99.9% of COVID-19 in a simulated home environment.

The benefits of the REME HALO whole home air purification system go beyond the important work of killing bacteria and viruses. The tight construction prevents outside air from circulating in your home. Inside air can be up to five times more polluted than outside air. Whole home air purification from Semper Fi is a breath of fresh air in your entire home.

How Does REME HALO Work?

REME HALO is installed in the supply plenum of your home HVAC system. It uses reflective electromagnetic energy to produce hydrogen peroxide plasma that passes through your air handler and circulates through your whole house. Hydrogen peroxide is naturally occurring in the atmosphere. It is part of the natural process of purifying the clean outdoor air that we breathe. The hydrogen peroxide produced by REME HALO continues to eliminate pollutants in your home even when the blower on your HVAC system is not blowing.

REME HALO is not a filtration system that works to capture the pollutants that are circulating in your home air. It kills and eliminates the pollutants before they circulate. Also, it works with your filtration system by causing particle pollutants to solidify and stick together, making them larger and easier for your filter to catch. Don’t forget to change your filter often.

REME HALO can be installed quickly by the professionals at Semper Fi. It comes with a five-year warranty. It is recommended that the cell be replaced every two years. Call the professional HVAC technicians at Semper Fi today to learn more about how whole home air purification can reduce the pollutants in the air circulating in your home. It’s the new normal; air purification will help keep your family healthy and safe.

Emergency Heating & Air Conditioning Repair Service

Emergency Heating & Air Conditioning Repair in the Phoenix East Valley


When the weather is at extremes, heating and cooling systems are working their hardest. When they are working their hardest, that’s when they tend to break down. They’ve also been known to break down on the day guests are due to arrive, the day you are leaving for vacation, and any other day you have too much going on. The correlation between an HVAC breakdown and you not having time to deal with one more crisis has not been independently verified. That’s why it’s called an emergency.

If you have a heating or air conditioning emergency, the technicians at Semper Fi are available seven days per week. If it is an emergency to you, it is an emergency to us.

Clearly, some situations call for emergency service. If your safety is at risk, that is an emergency. If your air conditioner quits on a scorching hot day, that is an emergency. Other situations are not that clear-cut. When the temperature is mild, a broken air conditioner or nonfunctional furnace is more of an inconvenience than an emergency. But that same inconvenience can be an emergency if you have young children, older residents, or health-compromising conditions.

Why Do Heating & Air Conditioning Systems Break Down?

No one actually wants to call for emergency service. It is always better for systems to work as they should and be there when needed. There are steps that can be taken to prevent breakdowns.

Preventive maintenance is number one on the list of steps to take to prevent system breakdowns requiring emergency services. For the most part, we don’t think of HVAC systems as needing regular maintenance. Alternately, it is understood that vehicles need proper service to keep them running. We don’t drive our vehicles until they break down on the side of the road. But some homeowners who are careful to follow maintenance schedules for their cars and trucks will go for years without getting their HVAC system serviced. Proper HVAC service involves more than just changing the filter every few months. Contact Semper Fi to arrange for your HVAC system to get a tune-up. Better yet, sign up for a preventive maintenance plan to get regular service. On each tune-up or maintenance visit, your Semper Fi technician will evaluate your entire system and identify components your technician recommends be replaced preventively or that cold fail in the next 12 months. Semper Fi offers an additional 10% discount for preventive repairs performed on a maintenance visit.

Your HVAC service technician at Semper Fi is a trained and certified professional. Do-it-yourself HVAC maintenance is generally not a good idea. Specialized tools and skills are required. It is always better to call a pro for HVAC. Improper or incomplete service can actually harm your systems and cause breakdowns requiring emergency service at the most inopportune times.

If your heating and cooling system is more than 10 years old, it is more likely to break down than a newer and more efficient system. You may be paying for preventive maintenance and regular tune-ups but still need frequent repairs and emergency service. You may be at the point where you need to consider replacing your system with a new high-efficiency system and say goodbye to expensive repairs and hello to trouble-free operations. But don’t ignore preventive maintenance on a new system. Talk to the pros at Semper Fi for help in selecting the right HVAC system for you.
