We've heard great things about Modern PurAir from HVAC techs to neighbours so we had high expectations. Our tech David was amazing. He went through what we should be expecting from the job itself, noise level, equipment around the house etc. Everything took longer then expected. (We had 2 dryer vents, 20+ ceiling vents, and our furnace was in the attic with a very small landing pad). He didn't complain once and was very pleasant and patient with the kids running around. Very attentive and cleaned up after he was done. Definitely left the place cleaner then when he came in. A couple weeks later he sent a personalized post card to follow up as a thank you. Not one of those generic fill in the blank ones but little details about his visit here with us. We would definitely use them again in the future. We highly recommend David as your tech.
