How To Get Your Heat Back Fast On A Freezing Night

Did your heat go out when it's freezing? Here are possible causes and how to get your heat working again fast.

Ignition or Fuel Supply Issues

When your heat suddenly goes out on a freezing night, it could be due to ignition or fuel supply issues. This means that your heating system is having trouble starting or maintaining a flame, resulting in no heat.

To identify this problem, check if your thermostat is set to heat and the temperature is higher than the current room temperature. Then, listen for any unusual clicking or humming sounds coming from your heating system. If you don't hear the comforting sound of your furnace igniting, there may be an ignition or fuel supply issue that needs a professional repair

Faulty Blower Motor

Another common cause of sudden heat loss is a faulty blower motor. This motor is responsible for circulating heated air throughout your home. When it malfunctions, the distribution of warm air is disrupted, leading to a lack of heat.

To identify a faulty blower motor, first, check if your heating system is running but no warm air is being blown into the rooms. Then, listen for any unusual sounds coming from your heating system, such as grinding or squealing noises. If you don't feel any air movement or notice irregular sounds, the blower motor may need to be replaced by an HVAC contractor

Frozen Condensate Line

A frozen condensate line can cause your heating system to shut down. The condensate line carries away excess moisture produced during the heating process. When it freezes, it blocks the drainage, triggering a system shutdown to prevent potential water damage or malfunction.

To identify a frozen condensate line, look for signs of water leakage or ice buildup around the furnace. You may also notice unusual gurgling sounds or a burning odor coming from the system. If your heat suddenly stops working, a frozen condensate line could be the issue. If you can't clear it yourself, call an HVAC contractor for an emergency repair.

Power Supply Interruptions

Power outages or electrical issues can cause your heating system to stop working. If there's no electricity reaching the system, it won't be able to function and provide heat.

To identify a power supply issue, check if other electrical appliances in your home are working. If everything else is without power, there might be an outage in your area. However, if only your heating system is affected, check the circuit breaker to see if any switches have tripped.
