Honest and professional, the project manager came here and he told us what no other company was telling us. The bad smell comming from our vent was not going to go away by simply cleanning it... it had to be replaced. The technician clean after themselves and know what they are doing. I recommend you go with them for any of this matters. Thank you! Out house is finally smell free.

I received quotes from various companies for a generator for my home. They were all very close in price. I very much appreciated Mr. Lester Smith and based my decision to choose Airmasters on his knowledge, and his thorough presentation. The four stars are because it took several weeks longer than anticipated but I do understand the reason for delay. I would recommend Airmasters and Mr. Smith in the future.

When our furnace froze up in single digit temperatures in January, 2024 I called Airmasters and they came as soon as they could and thawed the ice in drain going out of the house and we had heat in no time. The technician’s boss drove him to our house to do the work. That’s a very good boss! I love AirMasters!! Their maintenance plan is fantastic!
