Get matched with top geothermal heating or cooling system installers in San Marcos, CA

"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."

"I did not feel cheated and I got exactly what I wanted. Immediate service, competency without condescension, flexibility in hardware choices, reasonable pricing. My new sink faucet makes me very happy and now I know more about how to go forward w other projects if I so choose in the future."

"Carini installed my mini splits a few years ago and promised me the world with their warranties. Well, turns out they botched something during the install and all of the refrigerant leaked out. They want $2,200 to refill and re-pressurize the line. Since they cross-threaded the screw that led to the leak during installation, this should be covered under the "Lifetime Craftsmanship" guarantee. Instead, they're trying to charging me a full day of labor to fix their mistake. Support on this issue has been dismal. It's been 16 days since they first diagnosed the problem and I still don't have a timeline for when this will get fixed. I chose Carini because of their warranties and their service record, but its all smoke and mirrors. You've been warned."

"The heating system has been fixed and running."

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

"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"

"Josh and Daniel were great. Thanks so much"

"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."

"***DISHONEST COMPANY*** No written or verbal estimate provided for cost of repair. They refused to apply the $79 diagnostic fee towards the repair as they stated they would. First technician tried to lie and state that the heat exchanger was cracked to make us replace the entire system when it only ended up being a doubled HVAC filter placed by tenant. $378 total paid for labor and to install a $6.37 MERV 8 HVAC filter. Then numerous wasted phone calls just to get the final invoices. Management will NOT return calls to address any concerns for the consumer so any response saying to contact their office is just another lie."
