How to Know if You Should Replace Your Air Conditioner

Consider replacing your air conditioner if you notice one or more of these warning signs:

• Rising energy bills
• Uneven cooling throughout the house 
• Unusual noises or smells 
• Your AC is over 10 to 15 years old
• You’ve had to call for service more than once or twice in a season

How Long Do HVAC Systems Last?

On average, HVAC systems last 10 to 15 years in Tucson, AZ. The wide temperature swings put extra strain on equipment compared to milder climates.

If you’ve noticed higher bills, uneven cooling, or unusual smells, reach out to us for a consultation to determine whether you just need a repair or if a full replacement is necessary.

The Cost of HVAC Installation in Tuscon, AZ

The cost of a new HVAC system in Tucson depends on the size of your home, the type of unit, and whether ductwork or electrical upgrades are needed. In general, costs range from $6,300 to $11,500. 

While a new install is a big investment, the right system can deliver reliable comfort for more than a decade. Plus, you can opt for a payment plan to ease the burden of the cost.

What Time of Year is Cheapest to Replace HVAC?

In Tucson, the cheapest times to schedule HVAC replacement are in the fall or spring. This is when demand is lower and temperatures are more moderate. Dealers and manufacturers often offer promotions or rebates in those seasons, and contractors typically have more open scheduling, which can help you lock in a better rate.

The Cost of Typical HVAC Repairs

Minor repairs like replacing capacitors, thermostats, or small sensors can cost around $150–$400. Moderate fixes like refrigerant recharge or fan motor issues typically land in the $200–$600 range. Major component repairs like compressors and evaporator coils can exceed $1,000 depending on unit age, warranty status, and part availability.

How to Choose the Best Heating and Cooling Contractors

Picking the right HVAC contractor makes all the difference between a system that runs smoothly for years and one that gives you constant headaches. Before you sign a contract, consider:

• Asking for recommendations: Start with people you trust, like friends, neighbors, or coworkers who’ve had recent HVAC work done. They can tell you who showed up on time, who explained things clearly, and who to avoid.

• Researching company licensing and certifications: In Arizona, HVAC contractors must be licensed through the Arizona Registrar of Contractors. Look for proof of licensing, insurance, and certifications like NATE (North American Technician Excellence), which shows technicians are trained to national standards.

• Reading reviews: Scan for patterns in what people say on punctuality, pricing, or how well the company handled issues after installation. Multiple complaints about the same problem may be a red flag.

• Expecting a thorough home evaluation: A trustworthy contractor should check your home’s square footage, insulation, and run load calculations before recommending a system.

• Requesting detailed, written estimates: Always get estimates in writing and make sure they break down labor, equipment, and warranty details. That way, you can compare contractors side by side.
• Asking about warranties and guarantees: Ask how long the manufacturer’s warranty runs, what labor coverage you get, and whether they offer a satisfaction guarantee if something isn’t right.

Best HVAC Installers in Tuscon, AZ FAQs

Should HVAC technicians be certified or licensed?

Yes, in Arizona, HVAC contractors must be licensed through the Arizona Registrar of Contractors. This ensures they meet state requirements for safety and quality. On top of that, many of our technicians at Semper Fi are also NATE-certified so you know you’re getting the highest quality work for your home.

What should I ask when buying new HVAC?

Ask the basics, like how big of a system do I need for my home? What’s the efficiency rating? What kind of warranty is included? You should also ask how the contractor sizes the system, whether they offer financing, and what kind of maintenance plan they recommend after installation. 

At Semper Fi, we walk you through all of this during your in-home evaluation so you know exactly what you’re getting before you sign.

What brand of HVAC is the most reliable?

There isn’t one “most reliable” brand for every home. What matters most is choosing the right size and type of system for your space and having it installed properly. A top-of-the-line unit won’t perform well if it’s the wrong size or set up incorrectly. 

That’s why Semper Fi always starts with a full evaluation of your home, then recommends options that will give you the best performance and efficiency for Tucson’s climate. Reach out to our team, and we’ll help you find the right fit.
