Best Heating & Air Conditioning / HVAC In North York

“We had a furnace installed and the work was done on a timely manner. The installation was done on the hottest day of 2026 but that didn't stop the work on Reliance 's techs. Also the day prior to installation, Aria Shorki completed all the paperwork explaining the process very thoroughly.“

“Needed my hot water tank replaced and they were able to have a crew out the very next day. The price was very low compared to competitors.

Mustafa with North Strong HVAC and his installation crew was very professional and quick at getting the new unit installed. He made suggestions for a maintenance schedule and suggested I look into getting a water softener because of the issue I have been having with hard water.

Before they left he made sure I understood how the unit works and its settings. They also left the place cleaner than they found it. Thank you for everything, I will be contacting the Go Lime crew for my future needs for sure.“

“Max frm Aire Max was able to make time to service our airconditioner today instead of as planned tomorrow. He took into consideration it being a very hot day & we needed our airconditioner to be working ASAP. He came well prepared with the part that needed replacing (avoided having to order part & make us wait & suffer the heat). He explain in detail what the problem was, & provided guidance on how to care for equipment & furnace. He immefiately knew what needed to be done & was very thorough in completing the service required. I would definitely recommend him to family & friends.“

“I had to replace my rented water heater and I opted to buy it this time. After sending pictures, Mike responded quickly with a quote and detailed explanation of the process. On the day of installation, he called to confirm the technician’s name and confirmed the drop off of my old unit. After the installation, he followed up. This type of professionalism is hard to find these days and I sincerely appreciated the straightforward approach. The technician Ehsan was amazing as well, kept everything safe and tidy. I highly recommend DeMarkHome, Mike and Ehsan. Now I have someone reliable to call in case of need.“

He’s knowledgeable, efficient, and very quick to respond. Everything was explained clearly, and the work was done without wasting time. I highly recommend Mark to anyone looking for a reliable and competent HVAC professional.“

“Outstanding service from start to finish. I was referred to Home Trade Standards by a neighbour after my 28‑year‑old HVAC system finally gave out. They came out right away for an inspection and provided a clear breakdown of the issues, along with straightforward repair and replacement options and a detailed quote.

I chose to move forward with a full system replacement, and they had everything delivered and installed in under two weeks. George and Sasan arrived on time and were polite, professional, and extremely respectful of my home—using work blankets, wearing shoe covers, and leaving everything spotless.

I was extremely happy with the results and would recommend Home Trade Standards without hesitation.“

“Definitely recommend. Called Ray and he came out, assessed the problem, fixed it. I had called another company before R&Z, but they way overpriced and upsold the job. I knew it wasn't right so tried for a second option and called R&Z plumbing for the win! Also, Ray is friendly, respectful and pleasant to deal with. Great find.“

“We have been customers of free energy for over 50 years, a few new furnaces, air conditioners they have always been there for us, but the last two days changing from oil to gas was a very big decision on our part. I’m getting a new furnace and air conditioner. At the same time it seemed in my mind, a hard work but they pulled it off in less than two days. All the old is out all the new is in. We have heat tonight and it smells beautiful in here. My home is clean. My grounds are clean and they did a wonderful job. I would highly recommend them for anyone they’re there when you need them. You can call day or night with a problem and they come from the ladies who answer the phone to the gentleman who bring the oil or service thank you very much.“
