Best Heating & Air Conditioning / HVAC In Ontario

“Luis remove a blockage in my drain and replaced other plumbing needs, with a discount and a smile. He kept working hard until he got it all handled. Great job!“

“Thank you, Howie, for quickly addressing my urgent AC issue last Friday during the intense heat. We purchased our HVAC system from Diamond Air Service six years ago, and this was the first time it needed repairs. Howie was very professional; he thoroughly checked and tested the system before replacing the faulty part. I highly recommend this company for A/C systems; they are professional, courteous, and reliable.“

“We live in an older condo with no AC and Macawsome did a great job of working through the process with the HOA to install HVAC! We highly recommend Macawsome for your HVAC install or repair.“

“We hired them, through Costco, to install a whole-house water system. The installation went smoothly and the system has worked well. The installation crew was efficient, answered all our questions and removed all debris from the old water system.“

“Sanchez and his crew were just great! They explained everything that they were going to do with the attic insulation. They sealed off all the areas and got to work. They were very thorough and clean. We felt the difference in the house in no time.“

“Keeping It Cool Air Conditioning and Heating was a lifesaver for my elderly mother's home! After dealing with another company (to put it nicely—even though he doesn’t deserve it, one “gentleman”) who wouldn’t resolve the issue and was quite unprofessional, the KICHA team came in and completely took over with confidence, professionalism, and diligence. The team—especially Eddie and Tony—were amazing: thorough, professional, knowledgeable, and incredibly proactive. They quickly got to the root of the problem and had everything running smoothly in no time. It was a huge relief to finally have a team that knew what they were doing and genuinely cared about doing it right.

What meant the most was the peace of mind they brought—knowing my mother would finally be comfortable on those hot days. I can’t recommend Keeping It Cool enough!“

“Yet another great review for M&M - we had Ryan come out to do a full on maintenance for a family member's house for sale. Awesome as always!! We've been customer's for 11 years now. Theresa is great too - whenever I need a referral for anything home repair related I call them first. I wish I could give them a 10!“
