1. Your Furnace Is Making Strange Noises

One of the first signs that your furnace may need attention is the appearance of unusual noises. If you hear banging, clanging, squealing, or whistling sounds coming from your furnace, something could be wrong.

  • Banging or clanging: This could be a sign of a loose or broken part inside the furnace, like the blower or a metal panel.
  • Squealing: A high-pitched squeal could mean that the blower motor is worn out and needs lubrication or replacement.
  • Whistling: A whistling sound could indicate a clogged air filter or a ductwork issue that’s restricting airflow.

2. Your Furnace Isn’t Producing Enough Heat

If your furnace is running, but your home still feels cold, the issue could be as simple as a clogged air filter or as complex as a malfunctioning thermostat or ignition system. Poor airflow, whether due to blockages or failing components, prevents your furnace from heating effectively.

If you notice that some rooms in your home are warmer than others, or that your furnace isn’t reaching the temperature set on your thermostat, give us a call. We’ll perform a full diagnostic to determine the cause of the problem and get your furnace heating evenly once again.

3. Your Furnace Won’t Turn On

A furnace that won’t turn on at all is one of the most obvious signs of trouble. The cause could be a blown fuse, a tripped circuit breaker, a faulty ignition system, or even a dirty pilot light.

Before you panic, check the thermostat to ensure it’s set to "heat" and the temperature is set correctly. If everything appears to be in order, but your furnace still refuses to start, it’s time to call Jack Harrison Heating & Air Conditioning. Our HVAC technicians are experts in diagnosing and fixing furnace issues quickly.

4. Your Energy Bills Are Higher Than Usual

If you notice a sudden spike in your energy bills, your furnace could be working harder than it needs to. Several factors can contribute to inefficient furnace operation, such as a clogged air filter, failing components, or an aging unit.

An inefficient furnace can also result in uneven heating, leading it to run for longer periods. Scheduling an annual maintenance visit with our team at Jack Harrison Heating & Air can help you avoid unexpected repair costs and improve your system’s efficiency. We’ll clean and inspect all the components to ensure your furnace is running smoothly and efficiently. Ask about our VIP Maintenance Plan which is built to help remind you of the maintenance visit and keep your system in check!

5. You Notice Yellow or Flickering Pilot Light

If your furnace’s pilot light is yellow or flickering instead of burning a steady blue, this could indicate a problem with your furnace’s gas burner or the pilot light itself. A yellow flame may suggest incomplete combustion, which can lead to carbon monoxide buildup—a dangerous situation for your home.

If you notice this issue, turn off your furnace immediately and call our team. We'll inspect your system, clean the burner, and address any underlying issues that could be putting your home at risk.
