Juan came out today and was amazing. He was very thorough and informative and did a great job finding the problems with our a/c unit and ducts. We will be using them for al of our future a/c needs.

Overall a Great company! Professional, friendly, and HONEST. Matt and his crew were exemplary in their work. I purchased a new Trane Slim line AC Condenser and had it relocated to the other side of my property and the furnace relocated to the attic. They also relocated the air return and installed a new wi-fi smart thermostat (which my wife and I can now access remotely). Their work speaks for itself. I highly recommend Semper Fi Air to anyone. Please reach out if you have any questions, I’d be happy to tell you more great things about this company.

Called Semper Fi Air this morning and now my heater is working! Thank you thank you Juan. You and Matt were great. These guys are professional and their prices were reasonable. We will definitely use them again. Thank you again both for your service on my heater and for your service to our Country.

I can’t even begin to scream my praises of Matt & this company. During a heat wave when 20 other companies were to busy, Matt squeezed us in. The urgency was that we have a 4 days old premie in the house! Matt not only came and Fixed the AC he was honest. In the service industry honesty is very hard to find. We are now sitting here and j had to grab a blanket cause the AC works so well!! Highly recommend.
