Nov 17, 2021

Home furnaces are an essential part of home heating, but when it comes to cold weather, furnace issues can pop up. Some common problems include no heat at all, the smell of gas or oil, odd noises and a flue that won't close. But there's good news - almost all these furnace problems have simple solutions.


When there is a problem occurring at the furnace, it may not cause an error on the thermostat. The furnace will continue to heat as usual even though there may be some issues. It is important for homeowners to check their furnace more often during these colder months if they haven't already. Home Advisor recommends an annual inspection, by a professional, for your furnace especially in units over 10 years old. This way you can catch small problems before they escalate into larger more expensive ones.

What Is The First Sign Of Furnace Problems?

Ever turn the thermostat up on your central heating system and then wait—and wait, until you just can't stand it any longer? Then, finally, the click of the furnace kicking in lets you know that your house will be cozy again soon. There's nothing like a cold home to convince you that furnace repair is needed! Here are some common problems homeowners tend to experience with their furnaces in cold weather.


Electric vs Gas Furnace Problems


If you have an electric forced air furnace-Your electric bill has been sky high this past month because your furnace is constantly running trying unsuccessfully to keep up with keeping your home warm let alone at a comfortable temperature. Frequently these types of furnaces are undersized for the amount of square footage they are supposed to heat. A lot of times homeowners are not aware that they have undersized or insufficient heating until their energy bills skyrocket. This usually happens first on cold winter days when the temperature drops below freezing. If you have an electric furnace, there are some things you can do to lessen your utility bill.


If your home is being heated by gas forced air furnace-Are your furnaces blower constantly turning? Sounds like a clogged heat exchanger could be causing this problem. The natural gas flame may not be enough to efficiently heat the entire house, so more fuel is needed in form of electricity to compensate for the inefficient burning process. Often times homeowners will call for service because the fan noise has increased dramatically. This not necessarily mean that you have a heat exchanger problem. What you might have is a loose belt or even a bad blower motor requiring replacement. An annual check up should determine if any common furnace problems exist in cold weather and can be corrected beforehand while they are still small issues.


Is Your System Clean?

The furnace system is the heart of every house in winter season. During this time, it generates warm air that heats your home. If this system does not work well, you will feel cold inside your house especially when the temperature outside is freezing. There are common problems that homeowners experience with dirty furnace vents in cold weather. Dust and animal droppings may clog their pipes and cause a poor airflow. Another problem is moisture which can also block its running ducts.


Today's furnaces may look simple but you need professional help to accomplish regular maintenance on its parts which include cooling fan, blower motor, heat exchanger coils, combustion chamber insulation, air filter housing assembly-ductwork connection or damper mechanisms, burner assembly including ignition components and gas valve assemblies. Regular cleaning ensures that these parts will work well for a long time period without experiencing problems such as poor heating performance or electrical malfunctions caused by dust accumulation.
