3 Best HVAC Services in London, ON

What a great experience with Reliance! My air conditioner stopped working this past Saturday and wit h the hot temperatures in Toronto, being in the house this weekend was very unpleasant. Thankfully I got a visit from Sam today and he did a great job! He was very attentive and fixed all the issues with the equipment. Thank you again Sam! I can sleep better now.

Amir & Adam did a fantastic job installing our new furnace, A/C, and humidifier. They were polite, p rofessional, and explained in detail the functions and benefits of each product. Thank you for the wonderful service.

Joe was very helpful in explaining the problem with our air conditioner. He fixed it fast and cleaned up all the water that had leaked out. Great service.

I recently had my entire HVAC system replaced by M&K and had an amazing experience from start to finish. They installed a brand new furnace, added an AC (which I did not have initially), and water heater. The whole process was smooth, professional, and stress-free. The team was knowledgeable, respectful of my home, and took the time to answer all of my questions. Their workmanship was excellent, and everything was completed efficiently and cleanly. You can really tell they care about doing quality work and making sure the customer is happy. One thing I really appreciated was that they also handled the paperwork for returning my Reliance rental water heater, which made the process so much easier for me. They also installed and set up the smart thermostat that I had purchased separately without any issues. I’m already noticing a huge improvement in comfort and would absolutely recommend M&K Heating to anyone looking for honest, professional HVAC service.

I am absolutely delighted with the HVAC installation completed by the staff at M&K! I'm equally thrilled with the quality of the unit, which is right-sized and priced right for my home! Here is why I highly recommend them: Professional Work: The job was completed professionally. They even considered the aesthetics to keep my home looking good with no unsightly wiring. Extra Thoughtfulness: M&K ticked all of my boxes for what I wanted and needed. They even went the extra mile to remove an old flagpole holder that was damaged by a wind storm. That thoughtful care is so rare to find these days! Amazing Staff: Every single staff member was personable and highly skilled. I was thoroughly impressed from the very first call for an estimate through to the completed installation.

Mark was like a detective trying to figure out why our air conditioner wouldn’t turn on and his persistence paid off when he solved the problem. He even went the extra mile to show us how to clean the exterior unit, and he even took the grates off to show how how dirty it was and cleaned them for us with a hose. He was very polite, explained all the charges and provided recommendations for extra coverage. The booking process was easy too. We are very pleased, thank you so much.
