My house is older and has an outdated electrical panel, which made finding the right parts more difficult, but they handled everything professionally and still completed a very clean, high-quality installation. Reliable, knowledgeable, and easy to work with. Highly recommend!”

They put down protective coverings before starting the job to keep our floors clean, and when they finished, everything was spotless. The installation was quick, professional, and well organized.

“After calling a few HVAC companies around Ontario, we decided to go with Alex Air & Heating Services, and we’re glad we did. They arrived on time, diagnosed the problem quickly, and repaired our central AC without trying to sell us anything we didn’t need. The technicians were knowledgeable, courteous, and took the time to make sure everything was working properly before they left. Excellent service and a great overall experience. We’ll definitely use them again.”

“We’re currently doing a complete renovation of our home, so appearance was just as important to us as performance. I specifically asked for all the refrigerant lines and electrical wiring to be hidden inside the walls for a clean, seamless finish. That meant opening up sections of the walls, but the technicians handled everything with incredible care. Their cuts were clean and precise, and after running the lines, they repaired everything so well that you could hardly tell the walls had ever been opened. The attention to detail and craftsmanship were truly impressive. The entire installation turned out exactly as I had envisioned, and the final result looks beautiful. Professional, meticulous, and highly skilled—I would absolutely recommend them.”

“Fast, professional service with excellent workmanship. My new mini split works great—very satisfied!”

Fair pricing, professional service, and a smooth experience from start to finish.”

“We recently had a new central A/C system installed, and the team did an amazing job! They redesigned our ductwork and upgraded the system so our upstairs and downstairs can now be controlled separately with independent thermostats. This has made such a huge difference for our family. I live with my elderly mother, and she prefers a warmer temperature, while the rest of us like it cooler. Now everyone can set the temperature that’s comfortable for them without affecting anyone else. The installation was professional, the crew was knowledgeable, and they paid great attention to detail. Everything works perfectly, and we’re extremely happy with the results. I highly recommend them to anyone looking for quality HVAC work!”

I would absolutely recommend Alex Air & Heating Services to friends and family.”
