Fast Diagnosis, Right First Time

Furnace problems never seem to happen at a convenient time. When yours stops working, you need someone who shows up quickly, diagnoses accurately, and fixes it properly the first time. That's what we do.

Every service call starts with a full diagnostic. We inspect the heat exchanger, burner assembly, ignition system, flame sensor, blower motor, gas valve, safety controls, and flue before recommending any repair. Once we know exactly what's wrong, we explain it clearly and give you an upfront price before touching anything.

Emergency Furnace Repair

A furnace failure in a Mississauga winter is not something you wait out. When you're without heat and the temperature is dropping, we treat it as the emergency it is. We prioritize these calls and dispatch as quickly as possible, including evenings and weekends.

Furnace Diagnostics

Repair vs. Replace Assessment

Not every furnace problem warrants a repair. We give you an honest assessment of whether repair or replacement makes more financial sense for your specific situation — with clear numbers and no pressure.

Had a sudden leak in our furnace and received a quick response from Yuri. He sent one of his technicians, Michael, who came within a couple hours and was able to fix the issue at a reasonable price. Great experience with this company. Honest work and fair rates. Would use again.

I had a great experience with Beyond HVAC. They are very easy to deal with. I live in the Mimico/Park Lawn area and they were onsite within the hour. Michael resolved my heating issue for a great price, not having to replace the major components.

We are super happy to have found Beyond HVAC. We live in the South Riverdale / Leslieville area and were really impressed with the quality of his work. Yuriy is quick to respond, very professional and very knowledgeable. We had the tankless Navien NPE-240A2 installed. The installation was done neatly, all the venting and piping were organized well. During the installation, he also pointed out several issues with our previous setup that weren’t done correctly. He took the time to explain them and fixed everything properly, which gave us a lot of confidence that the system was installed the right way. I highly recommend him!!

Yuriy and Michael were consummate professionals - they laid out our options, provided clear communication and timely follow-ups. Could not be happier with their high service levels. Will likely be our go to for the foreseeable future. FYI: They replaced an aging water tank and serviced our furnace.

I came across Beyond HVAC while looking for a company that can perform routine tankless water heater maintenance and service in Etobicoke. I have used the installer before but he doesn't respond. I called in the morning and got a call back soon thereafter from Yuriy and set up an appointment for the next morning. I was thankful for the quick response time as well as the ability to set up an appointment relatively quickly. Michael came the next morning and was professional and courteous. He spent time to explain what he would do and after the service, he spent time to explain how it went and what I had to do (i.e. flush the pipes by turning on hot water at each faucet for 2-3 minutes). I would definitely use Beyond HVAC not only for tankless water heater maintenance but for other HVAC needs given my experience with them.

Beyond HVAC provided excellent service. We needed someone who provided service in the Etobicoke area to diagnose and repair our gas range. Yuriy responded to our requirements in a professional, prompt and customer focused manner. He sourced the part for us and went out of way to get it installed on Christmas Eve so that we could enjoy a Christmas dinner, for which we were very appreciative. He kept us fully apprised of the situation, following up at each stage of the service. His service was professional, complete and provided with excellent customer focus. We are completely satisfied. We will use him again for further service requirements.

Yuriy and Michael are very professional and knowledgeable. Michael was able to quickly diagnose and repair my malfunctioning furnace humidifier, and was happy to explain things as he worked. He went the extra mile to vacuum out some old renovation debris from the duct he was working on and cleaned up the work area when he was done. I'm glad to have a local HVAC professional I can trust!

Frequently Asked Questions

Furnace Repair in Mississauga

How quickly can you respond to a furnace breakdown in Mississauga?

For standard service calls we typically schedule within 24 hours. For emergencies where you're without heat, we prioritize same-day or next-morning response — including evenings and weekends.

Do you repair all furnace brands?

Yes. We service all major brands including Lennox, Carrier, Goodman, Keeprite, Trane, York, and others. We carry common parts for the most frequently serviced brands on our trucks.

What are the most common furnace problems you repair?

The most common issues we see are failed igniters, dirty or failing flame sensors, blower motor problems, tripped limit switches, and gas valve issues. Most of these are straightforward repairs that can be completed on the same visit.

Is a yellow flame on my furnace dangerous?

It can be. A yellow or orange flame often indicates incomplete combustion and the potential presence of carbon monoxide. Turn the furnace off and call us — this one shouldn't wait.

How do you decide whether to repair or replace a furnace?

If your furnace is under ten years old and facing a straightforward repair, fixing it almost always makes sense. For systems approaching 15 to 20 years old or facing a major component failure like a cracked heat exchanger, replacement is often the more financially sound decision. We give you the numbers and let you decide.

Do you serve Port Credit, Streetsville, and Meadowvale?

Yes. We serve all of Mississauga including Port Credit, Streetsville, Meadowvale, Erin Mills, Clarkson, Lakeview, Cooksville, and all surrounding neighbourhoods.

How much does a furnace repair cost?

It varies by the issue. Simple repairs like flame sensor cleaning or igniter replacement are among the more affordable service calls. Control board or gas valve replacements are more involved. We give you a firm price after diagnosis, before any work begins.
