Our Home Comfort Solutions

A comfortable home starts with more than dependable heating and cooling. Proper insulation, clean indoor air, efficient ductwork, and accurate temperature control all play an important role in how your home feels every day. At Semper Fi Heating & Cooling, we offer a variety of home comfort solutions designed to improve efficiency, enhance indoor air quality, and help you enjoy a healthier, more comfortable living space.

Attic Insulation

A well-insulated attic helps your home maintain a more consistent indoor temperature while reducing unnecessary strain on your HVAC system. Adding or upgrading attic insulation can improve energy efficiency, lower utility costs, and make your home more comfortable throughout the year.

UV Light Air Purifier Installation

A UV light air purifier works alongside your HVAC system to help reduce bacteria, viruses, mold, and other airborne contaminants circulating through your home. It’s an excellent option for homeowners looking to improve indoor air quality and create a healthier living environment.

Duct Sealing

Leaky ductwork can allow conditioned air to escape before it reaches your living spaces, reducing comfort and increasing energy costs. Our duct sealing services help improve airflow, increase HVAC efficiency, and deliver more consistent temperatures throughout your home.

Thermostats

Your thermostat serves as the control center for your heating and cooling system. We install programmable and smart thermostats that make it easier to manage your home’s temperature, improve energy efficiency, and maintain consistent comfort with greater convenience.

Isaiah did a great job flushing out my hot water heater. He was personable and professional while pointing out the reasons I needed to consider replacing my 18 yo unit. $49 was a great deal imo. I’d use Semper Fi again. ⭐️⭐️⭐️⭐️⭐️

They answered the phone on a holiday weekend, had a tech onsite in a few hours, brought in a temporary solution for the night and had people replacing the system the next day.

Same day service, technician was out to the house quick and diagnosed the problem. Within a few hours I had 2 technicians show up with all new equipment and started doing a whole system change. They stayed until the job was finished. Victor and Jason were very dedicated to ensuring the job was done correctly. So far a great experience with semper fi!

Brandon and Andrew were wonderful workers. They were extremely caring from the moment they came into my house till they left. They took time to make sure our unit was working at tip top shape and completely explained how my A/C works. They took before and after pictures of the places they worked on and were very proactive with Cleaning. As a senior on a fixed income the price for the tune up was extremely affordable. I cannot express how thankful I am to Brandon and Andrew for their mindfulness and honesty through this appointment. They are truly valued team members. Thank you Semper Fi for putting veterans/ military families first.
