Signs It's Time to Call a Furnace Repair Service
Furnaces require maintenance and the occasional repair to keep them running efficiently. Watch for these signs that it may be time to contact a furnace repair company.
Decreased Heat Output
If your furnace seems to be blowing colder air or struggling to keep your home as warm as usual, it likely needs some professional attention. Things like dirty filters or a cracked heat exchanger can reduce your furnace's heat output. A technician can clean and inspect your furnace to find and fix the problem.
Furnaces are designed to generate some operational noises, such as gentle humming or airflow sounds. However, if you start hearing new and unusual sounds like banging, grinding, or squealing, it could be an indication of underlying issues. These unfamiliar noises might be a sign of problems with components like the blower motor, gas valve, igniter, or other vital parts of the furnace. To ensure a safe and efficient heating system, it is always recommended to have a professional HVAC technician diagnose and repair the cause of these unusual noises. Their expertise will help identify and resolve any potential issues, keeping your furnace running smoothly and your home comfortable.
Higher Utility Bills
If your furnace has to work harder due to issues like a faulty thermostat, restricted airflow, or ignition problems, your energy consumption and costs can rise. A technician can pinpoint why your furnace is inefficient.
Strong burning odors coming from your furnace likely mean something is overheating. This could be a sign of a serious issue like a cracked heat exchanger leaking dangerous carbon monoxide. Turn your furnace off and call for repairs immediately if you detect burning smells.
Most furnaces last 15-30 years. After this time, parts wear out and problems occur more frequently. Once your furnace reaches about the 15-year mark, it's wise to have a professional perform a full inspection to see if replacement may be better than continuing repairs.
If your furnace seems to need professional servicing often, continuing repairs may not be worthwhile. Frequent issues are likely to mean fundamental problems that won't be resolved without major repairs or full replacement.
If your furnace isn't turning on at all, the issue may be as simple as a tripped circuit breaker. But electrical issues, a faulty control board, or a broken blower motor could also prevent your system from powering up. An expert can swiftly diagnose the problem.
Don't ignore signs of furnace trouble. Waiting often makes issues worse and leads to expensive emergency repairs. Schedule service when problems first arise to keep your heating system running reliably and efficiently.
