Furnace Repair in Coquitlam

Some no-heat calls have a simple cause. These checks are safe for any homeowner, and one of them might save you a service call:

• Check your thermostat. Make sure it's set to heat and turned above room temperature. If it runs on batteries, try fresh ones.
• Check the filter. A badly clogged filter can make a furnace overheat and shut itself down.
• Check the power. Look for a tripped breaker, and make sure the switch on or near the furnace is on. If the breaker trips a second time, leave it off and call us.

If that doesn't bring the heat back, stop there. Everything past this point involves natural gas, electrical parts, or both.

• Furnace won't start. A failed igniter, a dirty flame sensor, or a bad control board are common causes.
• Blowing cold air. The burners may not be lighting, or the furnace may have overheated and shut them off while the blower keeps running.
• Turns on and off too often. Technicians call this short cycling. It's hard on parts and can point to a blocked filter, overheating, or a dirty flame sensor.
• Strange noises. Squealing often points to the blower motor. A bang when the furnace lights can mean the burners are lighting late, which needs a look soon.
• Pilot light won't stay lit. Older furnaces use a standing pilot, and a worn thermocouple is a common cause.
• Higher energy bills or uneven heat. A furnace that's struggling runs longer to do the same job. That often shows up before a full breakdown.

A gas furnace burns natural gas inside your home, and a ventilation system of pipes carries the exhaust outside. When everything works, you never think about it. A cracked heat exchanger, a blocked vent, or a poor gas connection is different, because exhaust can contain carbon monoxide, which you can't see or smell.



That's why a furnace repair is more than getting the burners lit. Before the job is finished, the technician should confirm the furnace is lighting properly, venting properly, and shutting down the way it should. Our licensed gas fitters look after the gas work, so you aren't left wondering whether it was done right. A working carbon monoxide alarm is still worth having on every sleeping floor.

We start with what you've noticed, then diagnose the problem and inspect the parts involved. You'll hear what failed and what it will take to complete the repair before the work starts. Once it's fixed, we run the heating system through a full cycle to confirm it's in good working order.

Nobody wants to pay for a new furnace if a repair will do the job. If a repair is the better call, we'll tell you. A single failed igniter or sensor is rarely a reason to replace anything.

The cost of repairs starts to matter when the furnace is near the end of its lifespan, the same problems keep coming back, or a major part like the heat exchanger has failed. Parts availability and warranty coverage can also help you decide. If a new unit does make sense, a high-efficiency model can be worth comparing, and our furnace replacement page explains what's involved.

We work on the major furnace brands found in Coquitlam homes, including American Standard, Bryant, Rheem, and Trane. Not sure what you have? Read us the label on the furnace when you call.

Regular furnace service is the best way to avoid the next breakdown, so ask about it if yours has gone a while without a check.

How Much Does Furnace Repair Cost?

It depends on what failed. A sensor and a heat exchanger are very different jobs. Our rates page is a good starting point, and the technician will explain the repair before the work starts.

Why Is My Furnace Blowing Cold Air?

First check that the thermostat is set to heat and the fan isn't set to "on." If the air stays cold, the burners may not be lighting, or the furnace may have overheated. Check the filter, then call a technician.

Is It Safe to Run a Furnace That's Making Noise?

A faint squeak can usually wait for a booked visit. A loud bang when it lights, a burning smell, or a new grinding sound means you should turn the furnace off and call us.

Can I Repair My Furnace Myself?

You can check the thermostat, the filter, and the breaker. Anything involving gas, burners, or venting should go to a licensed gas fitter.
