Top Signs Your Heating System Needs Repair

When outside temperatures drop, our reliance on home heating becomes more critical than ever. Winter in Southeast Michigan can really put our heating systems to the test, especially if our furnace, boiler, or heat pump isn't operating at peak efficiency.

Before the coldest months hit, it's a good idea to review the warning signs that your heating system needs attention. With early action and proper maintenance, you can avoid more expensive repairs down the line.

If you notice any of these common signs, it may be time to contact an HVAC professional for a heating repair:

Common Signs Your Heating System Needs Repair

With prolonged use, any type of heating system can run into trouble. Here are some universal signs that your heating unit may need a repair — regardless of the type of system you have:

• Unusual noises like banging, hissing, or popping
• Higher-than-average energy bills
• Hot spots or drafty rooms
• Failure to turn on
• Foul odors

Signs Your Boiler Needs Repair

Boilers heat water and distribute the steam or hot water throughout your home using pipes or radiant floor systems. Boilers have specific issues that homeowners should look out for, like:

• Low water pressure: Inconsistent water pressure points to an issue with an internal component, like a faulty pump or blocked valve.
• Leaking: Be aware of dripping water or condensation around your boiler tank.
• Missing or yellow pilot light: A steadily lit blue flame indicates a pilot light with a good air-to-fuel ratio.
• Strange noises: Trapped air or a buildup of sediment can lead to banging, gurgling, or whistling sounds.
• No heat or hot water: If your boiler isn't doing its job, call a technician.

Signs Your Furnace Needs Repair

You'll notice different warning signs depending on the type of furnace you have:

Gas Furnace

Here's the most important sign you'll want to be aware of: Gas smells. If you detect any gaseous odors, leave your home and call a professional for a gas furnace repair immediately.

Also, look out for a yellow or flickering pilot light, which indicates a gas flow issue. A dirty filter or a ductwork blockage can restrict airflow, too, causing excessive dust to accumulate in your home.

Electric Furnace

If you have an electric furnace, one of the first signs to watch for is if your system turns on but produces no heat. A constantly running blower motor is another common malfunction, usually caused by a stuck fan relay.

And if your circuit breaker trips while you're cranking up the heat, there could be an underlying electrical problem like overheating.

If any of these issues sound familiar, contact our team to schedule an electric furnace repair.

Oil Furnace

With an oil furnace, pay attention to any unusual odors or smoke when the unit is running. Soot buildup inside the furnace can indicate an inefficient burning process, often caused by a clogged burner or poor combustion.

Oil furnaces that turn on and off too quickly are usually impacted by a thermostat or fuel supply issue. Rely on a professional for oil furnace repair.

Signs Your Heat Pump Needs Repair

A heat pump transfers heat between your home's interior and the outside air, offering heating and cooling. If it's not performing at its best, you may notice a few warning signs, like:

• Your heat pump struggles to maintain a consistent temperature.
• The blower fan continues running, even when it's not in use.
• Ice forms on the outdoor unit, even during mild weather.
• You hear strange or unfamiliar noises like grinding or squealing.
• There's a sudden rise in energy consumption without a change in daily use.
