What Our Clients Say
"I have been using Bob and his team for 18 years. Circulating Air is honest and reliable whether you are installing a new heat and air unit or having a service. They are prompt and respectful if your home." - Pat Manwell
"Bob is the most honest contractor I know, and I know a lot of contractors. His prices are fair and there is a reason he has all these 5-star reviews." - Justen Staufer
"When the company couldn't come to fix our heater because they were booked solid for the entire week (speaks well of the company), they referred a trusted competitor because they were concerned when we told them there was a small child in the home! The weather then was still warm enough, so we waited instead of using the competitor. A couple of days later, the company had an open spot and Tony fixed the heater. A few days after, the heater quit working again. Bob came out, fixed the problem at no additional charge. WOW! Honest, fair, wonderful people." - Chin Ong
