"I wanted to make sure my parents had a high-quality HVAC system that they could rely on. The team at HVAC Trust was professional, and the installation went off without a hitch. My parents are thrilled with how efficient it is, and so am I!"

The Nguyen Family

"With a new baby on the way, we needed a reliable air conditioner fast. HVAC Trust made the whole process easy from start to finish. The installation was smooth, and now our home is cool and comfortable. Couldn’t ask for better service!"

George P.

"After 20 years with my old furnace, it was time for a change. The HVAC Trust team was upfront about pricing, installed everything perfectly, and treated my home with care. I trust them completely and wouldn’t go anywhere else!"

Ibrahim A

I was really struggling to find the right heat pump for my home and had spoken to a few companies, but nothing felt right until I came across this amazing team. Dave in sales was a godsend—he took the time to explain all my options, didn’t push me into anything, and made sure I got exactly what I needed. Saira in customer service was equally fantastic...

Ronnie Singh

I had a fantastic experience with Jacky, who installed a new furnace in my Niagara Falls home. He was friendly, professional, and explained everything clearly. The installation was quick and clean, and he left no mess behind. Jacky truly cares about his work and his customers. I highly recommend him for any HVAC needs! Thank you, Jacky👍

Hamed Zahedi

Superb experience with HVAC Trust on a family member’s rental property in Windsor. They took care of all the details with the property management company and the tenant, they sent an experience technician to review a leaking HVAC condenser unit and deemed it’s best to replace the furnace and AC together since furnace was over 30 years old...

Daniel Makar

I had Jacky as a technician to install the new tankless hot water heater and Orik to install a water softener system. Both were very professional, showed up on time and worked quickly. They communicated what was being done and why it being done. The finance option makes upgrading your system much more accessible.

Abdullah ABDULLAH

I can’t recommend this HVAC company enough! My heat pump completely stopped working during one of the hot days. I called them, and they were at my door within a few hours! The technician Jamie and Mavi was super friendly and diagnosed the problem right away. Within an hour, the heat pump was up and running again, and the house was cool. What really impressed me was how efficient and professional the whole process was. If you need fast, reliable service, these guys are it!

Had problems with my old furnace. Talked to Dave before New years he set me up with a new Lennox efficient furnace . Jacky came today 2nd Jan 2025 and installed the new furnace, very professional and I am happy doing business with HVAC Trust . We have heat and amazing the price and workmanship and truly recommend and will always keep my business with this company.

Carol Dobbs

Just had a large Lennox furnace installed by Jacky and his assistant Kyle. They were absolutely wonderful to deal with and made the transition from our 25 year old Lennox furnace to a new one , in such a smooth manner. They made sure I was completely satisfied with the work before leaving. They cleaned up nicely and left no garbage. I am a bit skeptical when hiring new people these days, but...

Frequently Asked Questions (FAQ)

Answers to Common Questions About Your Heating, Cooling, and Indoor Air Quality Systems
If your furnace suddenly shuts off or stops heating during off-hours, check your thermostat and circuit breakers first. If everything seems normal but there’s no heat, give us a call. We offer emergency support and can dispatch a technician to your Markham home quickly, even during evenings or weekends.
Most repairs can be completed within one to two hours. The exact time depends on the issue and whether parts need to be replaced. Our technicians arrive with common tools and components to handle most problems on the spot, so you’re not left in the cold for long.
Not all heating issues require a full replacement. Many problems like a worn-out ignitor, faulty sensor, or clogged filter can be fixed easily. We’ll inspect the system thoroughly and only recommend a replacement if it’s more cost-effective than repeated repairs.
It’s best to schedule a furnace tune-up once a year, ideally before winter begins. Regular maintenance helps prevent breakdowns, improves efficiency, and extends your unit’s lifespan. It also gives our team a chance to catch small issues before they turn into expensive repairs.
Absolutely. A properly functioning furnace uses less energy and heats your home more evenly. If your system is working harder than it should, you may notice higher utility bills and colder spots around the house. Timely repairs and adjustments can make your heating more efficient and cost-effective.
