No heat

If your furnace blows cold air or will not turn on, especially in freezing weather, it needs to be checked.

Loud or unusual noises

Banging, screeching, grinding or squealing usually points to a mechanical problem or a failing motor.

Frequent short-cycling

A furnace that turns on and off constantly without bringing your home up to temperature may have a serious malfunction.

Yellow or flickering flame

A healthy burner flame is steady and blue. A yellow or flickering flame can point to a cracked heat exchanger or a carbon monoxide leak.

Strong or unusual odours

A persistent burning smell or a sharp, sulfur-like odour means you should shut the system down and have it inspected.

Rising energy bills

If your heating costs climb with no change in how you use your home, your system may be losing efficiency.

Safety first. If you smell gas or suspect a carbon monoxide leak, leave your home and call your gas utility or 911 from outside. Do not wait for a service appointment.

What to do next

  • Turn the system off if you notice an unusual smell or flame
