When it comes to furnace problems, they can range from a simple fix to something more complicated and costly. At AM/PM Heating And Cooling, we’ve encountered every type of furnace repair problem out there and are here to help you identify the cause and find a solution. Here are some of the most common furnace problems that we encounter:
The most common issue with furnaces is a faulty thermostat. If your furnace is not heating, the problem could be a defective thermostat or one that needs to be reset. Check to make sure the thermostat is set to “heat” mode and that the temperature is set higher than the current room temperature. If problems persist, you may need to replace your thermostat.
Dirty Air Filters
Another common issue is a dirty air filter. The air filter keeps dust and debris from entering your furnace, however if it’s clogged with dirt and debris, it can impair the efficiency of your heating system. Check the air filter often to ensure it isn’t dirty or needs replacing. We recommend changing the air filter at minimum twice each year for optimal performance.
Heat Exchanger Problems
The heat exchanger are heated coils in your furnace that transfers heated air that circulates throughout your home. It is important for the efficient operation of your furnace, as it helps ensure that your home is heated properly. If the heat exchanger becomes cracked or corroded, it will need to be replaced in order to keep your furnace working correctly.
Pilot Light or Ignition Issues
A furnace will not work properly if its pilot light or ignition is not working correctly. This is because the pilot light needs to be lit in order for the furnace to heat up and create warm air. If you notice that your pilot light isn’t working correctly and won’t stay lit, contact us as soon as possible for repair, it could be a sign of an issue with your gas line, air flow, thermocouple, or other components.
Dirty Furnace Burners
If your furnace is not heating up or you notice a strong smell coming from the unit, it may be due to dirty furnace burners. This means that dirt and gunk has clogged up the burner and needs to be cleaned or replaced in order for your gas furnace to work properly.
Noise From Blower Motor
If your furnace is making a loud whistling or squealing noise, it is usually caused by low airlow or a warn fan belt. In this case, you’ll want to check your air filter and the fan belt to see if they need replacing. If that doesn’t resolve the issue, contact us for professional diagnostic service.
Faulty Limit Switch
A furnace limit switch is a safety device found in most furnaces. It shuts off the furnace if it detects temperatures beyond its predetermined limit, which helps prevent overheating and potential fires. If the limit switch is faulty, it won’t be able to detect when temperatures are too high, so your furnace might overheat.
