Testimonials
Matt is one of the most delightful and inspirational men that has ever come to my home! I really mean that and can not genuinely express enough about what a treat it was for him to be the person to fix our 20+-year-old AC unit as the temperature soared to 90+ inside.
Marc T.Matt completed a quick, simple installation of a pretty large system. It involved a 36000 btu unit with wall mounts on three different rooms.
Andrew G.Matt was amazing! My dads air just quit this afternoon. We tried to make it though the evening but were dying. We called Matt and he showed up in 30 minutes! He was literally here 10 minutes, air was fixed and running! I will recommend him to anyone I know having AC problems! AMAZING

F.A.Q.
Frequent Questions
Why should I purchase a new heating or air conditioning system?
At Semper Fi Air, we realize that purchasing a heating or air conditioning system is no small matter. However, if your existing system is old, in need of repair or simply inefficient, purchasing a new unit, one which can be as much as 60% more efficient than a system purchased just 10 years ago, can offer long-term benefits.
Should I cover my outdoor unit in the fall and winter?
You should never operate an outdoor unit when it is covered. Covering the unit during operation can impede necessary airflow and can cause system damage. For details regarding your location’s HVAC system recommendations, speak to your local, licensed professional HVAC dealer. We hope this covers it all.
What is the proper size HVAC system for my home?
Sizing the equipment load requires the consideration of several factors. Ceiling height, construction, window size and placement and dozens of other variables all need to be considered to properly size a heating and/or cooling system. A professionally conducted load calculation is the foundation of an effective system.
Can frost, ice, dirt or other debris keep the outdoor unit of my cooling system from operating effectively?
Anything that prevents airflow from making its way to the outdoor coil may affect the efficiency and performance of your system. To avoid this, keep the space around the equipment clear. To determine if your unit is suffering from inadequate airflow, contact us. Blocked air flow to air conditioners and heat pumps can lead to larger problems. So let’s keep it clean, folks.
