A homeowner in Port Credit called us on a Sunday morning in January. Their furnace had stopped working overnight and the temperature inside had already dropped to 15 degrees. We had a technician there within a few hours. The issue turned out to be a cracked igniter — a common failure point on furnaces that age past ten years. We had the part on the truck, made the repair, and the house was warming up before noon. No one should spend a winter Sunday without heat in Mississauga. 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.

What We Fix

Common Furnace Problems We Repair

From complete breakdowns to subtle performance issues, our technicians are trained to diagnose and repair the full range of furnace problems.

No Heat at All

The most urgent situation. Common causes include a failed igniter, a faulty flame sensor, a tripped high-limit switch, or a gas valve issue. Each has a different fix — accurate diagnosis is the starting point.

Furnace Short Cycling

A furnace that turns on and off repeatedly without completing a full heating cycle is wasting energy and putting wear on components. Overheating due to restricted airflow, a faulty flame sensor, or a malfunctioning thermostat are the usual culprits.

Blower Running, No Heat

The fan is moving air but it isn't warm. This typically points to an ignition failure, a gas supply issue, or a tripped safety switch that needs investigation before reset.

Yellow Flame or Unusual Noises

A healthy furnace flame is blue. Yellow or orange flames indicate incomplete combustion and potential carbon monoxide — a safety issue that should be addressed immediately. Banging, screeching, or rattling noises all point to specific mechanical issues worth diagnosing promptly.

Our Repair Process

How We Diagnose & Repair Furnaces

We stock common furnace parts on our service vehicles, so most repairs are completed on the same visit. After the repair, we run the furnace through a complete heating cycle and verify safe operation before we leave.

Igniter & Flame Sensor

Replacement of failed igniters and dirty or failing flame sensors — among the most common furnace repairs we perform.

Heat Exchanger Inspection

Thorough inspection for cracks or damage. A cracked heat exchanger is a safety issue that requires immediate attention.

Blower Motor & Capacitor

Diagnosis and replacement of blower motors and capacitors that are causing airflow issues or complete blower failure.

Gas Valve & Control Board

Diagnostics and replacement of gas valves and control boards — more involved repairs that we handle with precision.

Limit Switches & Safety Controls

Replacement of high-limit switches, pressure switches, rollout switches, and other safety controls.

Thermostat & Wiring

Diagnosis of thermostat communication issues and wiring faults that cause erratic or no furnace operation.

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!

Honest Advice

Should You Repair or Replace

When Repair Makes Sense

If your furnace is under ten years old and facing a straightforward repair, fixing it almost always makes sense. We'll give you a firm price and get it done on the same visit in most cases.

When Replacement Is Smarter

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. Homeowners in Port Credit and Streetsville with older furnaces often find that the cost of a major repair, combined with rising energy bills from an inefficient system, makes replacement the smarter move.

Honest Advice, No Pressure

A cracked heat exchanger is a safety issue — it can allow carbon monoxide to enter your living space. If we find one, we'll tell you clearly and explain your options honestly. We won't leave you in a dangerous situation or pressure you into a decision you're not ready for. We'll give you the numbers so you can decide for yourself.

Frequently Asked Questions

Furnace Repair in Mississauga

How quickly can you come for a furnace repair in Mississauga?

Standard service calls are typically scheduled within 24 hours. For emergency situations where you're without heat, we prioritize same-day or next-morning response. Contact us directly and let us know it's an emergency — we'll do our best to get there fast.

What does a furnace repair service call cost?

We charge a diagnostic fee to come out and identify the problem. Once we know what's wrong, we give you a firm price for the repair before any work begins. You decide whether to proceed. The diagnostic fee is applied toward the repair if you choose to go ahead.

My furnace turns on but the house isn't getting warm. What's wrong?

Several things can cause this — a dirty air filter restricting airflow, a malfunctioning blower motor, a partially blocked heat exchanger, or a thermostat issue. We'll diagnose the specific cause and give you a clear explanation of what we found.

Is it safe to run my furnace if it's making a strange noise?

It depends on the noise. A banging sound on startup often indicates delayed ignition — worth addressing promptly. A screeching noise usually points to a blower motor bearing. A rattling could be a loose panel. If you smell gas or see a yellow flame, shut the furnace off and call us — that one shouldn't wait.

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.

Do you repair furnaces in Port Credit and Streetsville?

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

My furnace is making a banging sound when it starts up. Should I be worried?

A banging sound on startup usually means delayed ignition — gas is building up slightly before it ignites. It's worth having looked at promptly as it puts stress on the heat exchanger over time.

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.

What if my heat exchanger is cracked?

A cracked heat exchanger is a safety concern because it can allow combustion gases including carbon monoxide to mix with the air circulating through your home. We'll explain exactly what we found and what the repair or replacement options are — clearly and without pressure.
