Common Heater Problems

While we hope our heaters will work when we need them most -- especially during the middle of winter -- from time to time they can encounter problems. Some of these issues can include:

  • Uneven and inconsistent heating throughout your home. If certain rooms in your home are warmer than others, it can indicate that your unit is failing.
  • The system shuts down unexpectedly -- without reaching the desired temperature. This can be caused by faulty wiring, a failing pilot light or a malfunctioning thermostat.
  • The system takes too long to heat up your home. If your thermostat is turned up and your home still isn’t getting warmer, it can be due to leaky air ducts, a damaged fan motor or a problem with the belts and bearings.

Ways to Save on Cooling Costs

Keeping your home cool in the summer months can take a toll on your utility bills. Fortunately, there are ways to trim expenses.

  • Make sure your home is properly insulated to keep the cool air in and the hot air out.
  • Replace the air filters regularly to keep the air conditioner running efficiently.
  • Schedule yearly maintenance on your unit.
  • Use a programmable thermostat to keep the house at a consistent temperature.
  • Turn the thermostat down a few degrees. This will allow your unit to run less and you are unlikely to notice the difference.
  • If you have an older unit, replace it with a new model.
  • Use fans to circulate the air to make your home feel cooler.
  • Keep the drapes or shades closed in the afternoon to keep the sun out of your house and eliminate extra heat.

Having your heating or cooling unit fail is stressful enough -- don’t let the pending bill add to your anxiety. Ask us about our financing options!

Signs Your Furnace Needs Repairs

To avoid having your furnace malfunction unexpectedly in the winter months, it’s important to get it repaired by a professional at the first sign of trouble. Some signs to watch for can include:

  • Short cycling: If your unit runs for less than three minutes before shutting off unexpectedly, it can indicate a malfunctioning heat exchanger, or an issue with a thermostat.
  • Irregular flames: If the flames in the burner are uneven or leaning towards the back of the unit, it can mean that your burners are dirty, or it could signal a more serious issue like a cracked heat exchanger.
  • Unusual sounds: If you start to hear unusual noises like rumbling, popping or whistling, it can indicate an issue that needs to be inspected by a professional.
  • Cracked heat exchanger: If anyone in your family starts to feel ill, or you notice condensation on the windows or the pilot light turns from blue to yellow, it can indicate a carbon monoxide leak that can be caused by a cracked heat exchanger. This can be a very dangerous situation for you and your family, so it’s important to quickly evacuate the property and call a professional.
