Most Common Furnace Problems

Detecting furnace issues early on can save you a lot of time, money, and aggravation. Scheduling yearly maintenance on your HVAC system helps to find these complications before they evolve into much bigger and more expensive problems. Here are some of the most common furnace problems that homeowners face.

  • Faulty Thermostat

Is your fan constantly running? This is a sure sign that your thermostat isn’t working the way it should be.

  • Odd Noises

You should never hear banging, rattling, or pinging noises coming from your furnace. These sounds can be caused by several different issues and should be diagnosed by one of our trustworthy heating technicians.

  • Furnace Isn’t Blowing Air

This is typically a sign that your blower is clogged by debris, however, if you see a flashing red light on your blower, it’s time for a repair.

  • Yellow Pilot Light

If your pilot light is flickering or has a yellow flame, remove your family and pets from the home and call one of our HVAC experts immediately. This sign could mean there is excessive carbon monoxide in your furnace. Carbon monoxide is a colorless and odorless gas that is extremely deadly, even in small amounts.

  • Dirty Filters

Clogged filters can cause your furnace to work overtime to heat your home. Not only can this create wear and tear on your heating system and increase your energy bills, it can also lead to damage to your limit switch (see below).

  • Malfunctioning Limit Switch

If your furnace is continuously blowing, even when it shouldn’t be, there is a good chance your limit switch isn’t functioning properly and should be thoroughly inspected.

  • Frequently Cycling

Does your furnace kick on frequently, maybe even after it is just turned off? Several problems could cause continuous cycling, all of which one of our highly skilled furnace technicians can repair for you.

  • Damaged Blower Belt

If you hear a high-pitched squealing sound coming from your furnace, chances are your blower belt is frayed or broken and needs to be replaced.

  • Cracked Heat Exchanger

A cracked heat exchanger is a costly repair that can be caused by overheating your home or by neglecting to regularly replace your air filters.

  • Worn Out Ball Bearings

If you hear a scraping sound coming from your furnace, immediately turn it off and call one of our heating experts. This is a sign that your ball bearings, components that help the motor work properly, are worn out and need to be replaced.
