5 Signs That Could Indicate Your Furnace Needs Repair

It’s the winter season, and San Mateo homeowners will be running their furnaces more frequently as temperatures drop a bit at night. Many homeowners have HVAC systems with a furnace as part of that system, and you want to ensure that it works efficiently all season long, so you can enjoy a comfortable home and low energy bills. Apart from your furnace not working at all, how can you know if it may need repair so that you can count on it to get you through until spring? Here are a few signs that could indicate a problem.

Sky high electric bills. If your electric bill is higher than usual, it could be that your furnace isn’t performing efficiently. This could be caused by any number of issues – contact your San Mateo HVAC contractor to diagnose the problem.

Air quality – and your family – seem to be suffering. A furnace that isn’t functioning properly could mean that dust mites, mold, and other irritants are circulating through your home, increasing the number of respiratory illnesses your family is experiencing such as asthma, allergies or sinus problems. The problem could be in the ducts, so have them checked before winter sets in full force.

Your furnace is an antique. Most furnaces last for about 10 to 20 years before it becomes necessary to replace them. If yours is older than 15 years, start bracing for the fact that replacement may be necessary at any time – and plan for it sooner rather than later.

All kinds of strange noises, and your house isn’t haunted. Bangs, clangs, whining, grinding – a furnace that’s in need of repair can make all kinds of frightening sounds. While no furnace is completely quiet, it isn’t normal to hear these kinds of sounds. It could be something as simple as a loose belt, or there may be an ignition problem that needs correcting. Call your HVAC contractor to check things out before it becomes a bigger (and more costly) headache.

Yellow pilot light. Many homeowners really don’t pay that much attention to the color of the flame, and assume that if the pilot light is lit, all is well. A yellow flame could mean carbon monoxide gases in your home. Blue is what you want to see, as a blue flame indicates gases that are ideally balanced. If the flame is yellow, it could be that your furnace’s gas combination is not in good condition.
