I live in a townhouse condo which has the air compressor on the roof. Due to the age, it was time to have it replaced as well as the HVAC air handler within the house. Michael came over to give us the estimate. He was friendly and professional. We decided to shop around, just in case, after his visit. Well, shopping around was a complete waste of time! One company was more expensive by about at least 5K and another company backed out due to them not being equipped to replace a roof top air compressor - even though I told them about this over the phone. I then booked with Aire One. Friendly people, efficient, and they took on the job with no hesitation. I’m extremely pleased with results and highly recommend this company.
