"I’ve had the pleasure of working with Bill and Cool Air Technologies on several occasions and they never disappoint. They’ve done a HVAC replacement as well as an entirely new HVAC system install with impeccable results. They were professional and communicative; answering all my questions and working through any issues promptly. I will look nowhere else for my HVAC needs and highly recommend them to anyone considering their services."

"Quick response. "

"Josh was able to help us out less than 24 hours after I called. We had no AC and it was very hot in our home. He called ahead of his scheduled visit and was able to arrive earlier. He was very efficient, knowledgeable and friendly. We discussed future work replacing equipment and will definitely contact Josh to do the job."

"courteousness and prompt callback"

"What a great team! Fast, professional, knowledgeable, and did it at a fair price. I will recommend them to friends."

"Josh and Daniel were great. Thanks so much"

"Fausto Construction is the best I’ve ever worked with! I’ve dealt with contractors who met deadlines but delivered mediocre work, and others who were meticulous but took forever to finish. Fausto struck the perfect balance—paying attention to every detail, producing high-quality work, and completing everything on time. Since I don’t live near my condo, I needed someone I could trust completely, and Fausto did not disappoint. He provided regular progress updates with photos, and the communication was excellent. Thanks to Fausto, my condo now has stunning new floors, a high-end shower, and beautiful finishing touches that make it feel brand new while preserving its beachy charm. He listened to my ideas, made thoughtful suggestions without any hard upsell, and truly cared about the final result. I’m beyond happy with his work and will absolutely use Fausto Construction again for my next big home improvement project!"

"Great technician."

"My AC's secondary drain was leaking due to a clogged primary line. Daryle from Cool Air quickly identified the issue and cleared the clog under the master bathroom sink — about a gallon of water came out instantly. The final charge was a bit more than quoted, but Daryle was honest, efficient, and didn’t try to upsell anything. After bad experiences with Service Champions — who I believe sabotaged my system — working with Cool Air was a relief. Vadim, the owner, was also great to talk to. I’ll be using them again."
