Common Heating Furnace Repair Issues and How to Fix Them
February 17, 2025
In case your heating furnace gives way and refuses to work, you are left infuriated. There are times like in the cold winter night or in the early morning when it does not work. Anyway, for most heating furnace problems, it is not difficult to fix with some guidance. Here, we explain some of the common and major problems related to the furnace and how to deal with them.
One of the most common problems that homeowners have to deal with is that the furnace will not turn on. It has been known to be as simple a thing as a tripped circuit breaker or a blown fuse. Before you check with a professional, check the electrical panel to make sure the furnace's breaker is switched on. If the breaker is fine, then fuse replacement should be considered. If this did not take care of it, then it may be time to call in a professional since the problem might run deeper in electrical problems.
A faulty furnace is another common problem, whereby the device does not heat up the house at all. The furnace blows air but does not warm the house; in such a case, the prime suspect is a dirty air filter. It of course restricts airflow and makes the furnace overheat and eventually shut down. Fixing an air filter is a moderately fast and easy job. If replacing the filter does not take care of it, you may need an expert to check on the thermostat or pilot light.
Another indicator associated with type furnace problems will be the presence of strange noises. If any rattling, banging, and squealing are evident, there is a high chance that one or more parts are loose or worn out in your furnace system. A squealing noise is often a sign that the blower belt needs lubing. Banging may mean that the burner is dirty. Usually, these problems are offset by compliant maintenance and checks by the professionals, but strange noises will serve as a signal to the owner to have it looked at rather quickly to avoid sometimes more extensive damage.
The situation might also point to an adjustment fault in the ignition system. If your furnace cycles poorly and you end up adjusting your thermostat over and over again, it may be quite possible. The faulty thermostat is likely to cause the furnace to open and close the circuit at erratic times. Whereas ignition system issues can cause the heating to be inconsistent. Both cases require the attention of a licensed HVAC technician.

How a Furnace Works
The furnace system, which basically ensures winter warmth, remains the beating heart of heating in the home. Knowing how a furnace operates will assist you in understanding the necessary maintenance and conservation of energy efficiency.Thermostat Signals the Furnace: The very first step commences when the thermostat registers that the temperature within the house has dropped below the predetermined level. The thermostat signals the furnace to switch on.
Ignition and Fuel Source: Most furnaces work on natural gas, propane, or electricity. Gas furnaces ignite their burners using either a pilot light or an electronic ignition. An electric furnace heats air with its heating elements.
Heat Exchanger Heating Air: Burners heat a chamber called the heat exchanger, which in turn transfers heat to the air. This guarantees that clean, warm air will be blown into your house.
Blower Coils Warm Air: This fan blows the heated air through the duct system to various rooms in your home. Some vents in the rooms let warm air in while other vents pull cooler air back for reheating in the furnace.
Venting Out of Exhaust Gases: In gas furnaces, combustion results in the formation of byproducts like carbon monoxide. A flue pipe vents these gases safely outside to keep your indoor air safe.
Furnace Cycles Until Desired Temperature: So the furnace continues cycling till the thermostat senses that the temperature inside has hit the same value as set by you and turns off till it needs to come back on.
