Common Reasons for Furnace Repairs

Posted in: Furnace Repair

For homeowners in Dayton, a malfunctioning furnace can be a serious inconvenience, leaving you out in the cold without working heat on a cold winter day. Even for homeowners who are diligent about scheduled maintenance and regular heating tune-ups, furnace repairs may still be necessary from time to time. Here are some of the most common reasons why a furnace might need to be repaired. Your trusted HVAC professional will be able to tell for sure what’s wrong with your furnace, and will now what kind of repairs to perform in order to get it working correctly again.

  • Lack of Maintenance. Regular maintenance is the key to preventing the need for potentially costly furnace repairs. Your home’s furnace is an expensive piece of equipment, so taking proper care of it is well worth the investment. Proper maintenance will prevent breakdowns, as well as increasing your furnace’s energy efficiency and ensuring your home’s safety.

  • Clogged or dirty filters. A dirty filter will restrict air flow, compromising the ability of your furnace to work properly. If the filters are clogged, your furnace has to work harder to maintain warm air flow throughout your home, translating into higher energy costs. It’s important to replace your air filters at least once a month to keep your furnace running smoothly and efficiently. Clean filters will also improve the air quality inside of your home.

  • Mechanical wear and tear. Your furnace is a complicated machine with many intricate, complex internal parts, all of which are subject over time to mechanical wear and tear. Internal parts like belts and bearings can often wear down over time, necessitating heating repairs to replace or repair these components.

  • Pilot or ignition problems. Sometimes, a malfunctioning furnace is having a problem with its ignition or pilot light. Most furnaces use one of two types of ignition system: “hot surface ignition” or “intermittent pilot ignition.” Either of these types of system can experience a number of problems that create a need for professional repairs.

  • Gas or propane flow is blocked. If you have a gas furnace, the flow of natural gas or propane could be blocked or otherwise inhibited, leading to an inability of your furnace to function correctly.

  • A tripped or blown fuse or circuit breaker. If your furnace isn’t running, the culprit could be electrical in nature. It’s always important to have a certified HVAC professional repair these issues, since working with electricity can be extremely dangerous for a novice.

  • Thermostat issues. In some cases, the problem isn’t with the furnace at all; rather, it’s with the thermostat.

  • Leaky ducts. If the furnace itself isn’t the problem, you might have a leak somewhere in the ductwork in your home. Cracks, broken seals, or faulty insulation can cause hot air to leak out, making it harder to heat your home effectively.

Whatever the problem is with your furnace, a trained professional HVAC technician will be able to figure out for sure what is going wrong. They’ll then be able to safely, effectively perform the necessary repairs to restore a comfortable temperature to your home.
