Some furnace issues require a complete replacement, while others can be resolved with a professional furnace repair. Knowing what types of issues can be repaired can help you make informed decisions when your heating system starts malfunctioning.
Some of the most common furnace problems that can typically be repaired include:
Lack of Warm Air
If your furnace is running but not blowing warm air, it could be due to a variety of issues such as a malfunctioning thermostat, clogged air filters, or a faulty pilot light or ignitor. These issues can usually be addressed with relatively simple repairs like recalibrating the thermostat, replacing filters, or fixing the ignition system.
Rising Energy Costs
A sudden increase in your energy bills may signal that your furnace isn’t running efficiently. This could be caused by dirty filters, a malfunctioning blower motor, or even leaks in the ductwork. A professional technician can diagnose the problem and make necessary repairs to restore your furnace’s efficiency and help lower your energy costs.
Strange Noises
Strange noises like banging, rattling, or squealing coming from your furnace can be alarming. These noises are often signs of mechanical issues, such as a loose or broken part, worn-out bearings, or problems with the blower motor. In many cases, these components can be repaired or replaced without the need for a full furnace replacement.
Uneven Heating Throughout the Home
If certain areas of your home are warmer or cooler than others, your furnace may be struggling to distribute heat evenly. This could be due to issues with the ductwork, a malfunctioning blower motor, or an improperly sized furnace. In many cases, repairs to the duct system or adjustments to the furnace can resolve this uneven heating problem.
Short Cycling
Short cycling occurs when your furnace turns on and off frequently without fully heating your home. This can be caused by a variety of factors, including a dirty air filter, thermostat issues, or a malfunctioning heat exchanger. A technician can diagnose the cause of the short cycling and make the necessary repairs to ensure your furnace operates efficiently.
By addressing these common furnace issues through professional repairs, you can often extend the life of your heating system and avoid the cost of a full replacement.
