5 Signs Your Heating System Needs Repair

Your heating system works hard to keep you warm. Keeping an eye out for any signs your heater needs repair can prevent an unexpected breakdown at the worst possible time.

While some noises from your system, such as the whoosh of air or a brief click upon startup, may be expected, other sounds aren’t. If you hear rattling, squealing, banging, or hissing, this is a sign that your system needs professional repair.

High Energy Bills

With chilly winter weather on the way, your heating system must work hard to keep your family warm. Unfortunately, the constant use of your heating system can cause it to wear down and need repairs eventually.

Seeing an unexpectedly high energy bill can signal that your heating system isn’t working efficiently. If your energy bills are suddenly skyrocketing, contact Set Point heating and cooling as soon as possible to schedule a repair.

A clogged air filter or a thermostat that doesn’t function properly could be to blame for higher energy bills than usual. You may also need a new furnace that is more appropriately sized for your home. Regardless of the source, a sudden increase in energy bills indicates something is wrong with your heating system.

Noises

Although some creaking and moaning when your heating system kicks on is regular, any unusual sounds should be a red flag for repair work—especially rattling, which can indicate loose or broken parts.

You should also be aware of squealing and banging noises, which often signal belt or fan problems. If your furnace suddenly starts short cycling, that’s a terrible sign and could cause your system to break completely. Lastly, leave the house immediately and call for emergency repairs if your carbon monoxide alarm goes off. Carbon monoxide is a dangerous gas that can accumulate in your home. Exposure to this gas can cause flu-like symptoms.

Temperatures

When a part of your home feels more relaxed than the rest, it’s a clear sign that your heating system isn’t working correctly. Often, this problem stems from blocked or clogged vents or registers. Dirt, dust, furniture, or pet hair can block these openings, preventing air from reaching its intended destination and creating an uneven temperature throughout the room.

Another cause of uneven temperatures is a cracked heat exchanger, which can release carbon monoxide, a colorless and odorless gas that’s deadly when inhaled. If you’re concerned about carbon monoxide, evacuate the area and call emergency services immediately.

A professional inspection will determine the underlying cause of your uneven temperatures and recommend appropriate repair solutions. For example, a duct cleaning or a new zoning system can help you achieve the even home temperature you want.

Smells

A funny smell that doesn’t go away is a surefire sign that your heater isn’t working as it should. The funky odor usually results from an electrical or mechanical problem, such as a burnt-out part or overheated motor.

Any squealing or banging noises are also bad news. These indicate that your system’s blower isn’t delivering enough air or the thermostat is not communicating correctly with the furnace.

Sometimes, the heater could release carbon monoxide into the home’s air. Carbon monoxide is a hazardous gas that is odorless. It can cause itchy eyes, headaches, and even death in high amounts.

Low Temperatures

If you’re experiencing cold air throughout your home or areas that don’t seem to be getting heated, this is a sign that your heating system needs repair. Whether your system cannot turn on or your thermostat is disconnected, this problem must be addressed immediately to ensure you get the warm, cozy comfort you deserve.

A foul, burning smell is another common sign of a heating system that needs repair. While the initial odor typically dissipates once the procedure begins operating, addressing the issue immediately is essential.

Also, if you notice that your house seems to be extra dusty or smoky, this is likely an indication that the system isn’t functioning correctly and is not circulating enough clean air.
