How To Avoid Heating Emergencies This Cold Season

3 Signs That a Furnace Might Need Urgent Repair

A furnace is essential in making the home environment more favorable in the cold seasons when the temperatures are unbearably low. For homeowners and residents who require consistent heating, a home furnace provides a convenient option. However, just like most appliances, the furnace may break down after prolonged use. Most people rarely detect when their furnace malfunctions until it's too late. By then, they are freezing in a cold house. 

In this article, homeowners will discover the top signs that suggest it is time for furnace repair. 

The Furnace Blows Cold on Chilly Nights

One of the most common signs of a broken furnace is a failure to deliver the required amount of heat. Some common reasons why a furnace would produce inadequate heat include:

  • Damaged thermostat: When the thermostat malfunctions, the furnace struggles to generate heat and may shut down completely. 
  • Leaking ductwork: This allows already-treated and converted air to escape resulting in lower heat produced by the furnace. 
  • Overheating: Strangely enough, when furnaces overheat, they may end up releasing cold air thanks to a pre-installed safety device meant to protect homes from fires and other dangers of excessive heat. 
  • Dirty flame sensors: A gas burner may switch on and off continuously because of a dirty flame sensor. 

A Noisy Furnace Is a Faulty Furnace


A noisy furnace can be very annoying and uncomfortable to the homeowner. That aside, it is also a sign of an underlying furnace problem. Different furnace sounds indicate various issues; for example, a squealing furnace may suggest that the fan belt is loose or lacks enough lubricant. 

A thumping sound could signify an out of balance motor or an unbalanced blower wheel. Alternatively, a humming sound may indicate the presence of a loud transformer. 

Homeowners can solve some of these furnace problems by installing new filters and oiling the blower motors. 

It is, however, advisable to contact water heater installation professionals in case of any furnace emergencies. This helps avoid further damages to the entire furnace, which exposes the home to the danger of freezing in the winter. 

Leaking Gas Is Dangerous

The presence of leaking gas is one of the most dangerous situations homeowners may face at some point in their lives. When this happens, homeowners should trace the leaking gas to the source to identify the reason for the leak. This kind of leak can smell like a rotten egg due to the sulfur component present in the gas. One of the most common places to check for a gas leak is at the corroded areas in different parts of gas lines. 


Apart from smelling a gas leak, homeowners should be wary of any hissing sounds around the house. In case of a gas leak situation, the best thing to do is to shut down the furnace, evacuate the building, and notify the fire department immediately.
