Furnace Struggling To Keep House Warm
As the temperatures drop, the last thing you want is for your furnace to struggle to keep your house warm. Not only is it uncomfortable, but it can also lead to higher energy bills and potential damage to your furnace.
If you find yourself in this situation, don’t panic. There are several common issues that could be causing your furnace to struggle, and most of them can be easily repaired. In this article, we’ll discuss some of the most common furnace troubleshooting tips to help you get your furnace back up and running efficiently.
Why Is My Furnace Struggling To Keep My House Warm?
There are several reasons why your furnace may be struggling to keep your house warm. Some of the most common issues include:
Dirty Air Filter
One of the most common causes of furnace issues is a dirty air filter. When your air filter is clogged with dust and debris, it restricts airflow and makes it difficult for your furnace to distribute warm air throughout your home.
To fix this issue, simply replace your air filter with a new one. It’s recommended to change your air filter every 1-3 months, depending on the type of filter and the level of usage.
Faulty Thermostat
Another common culprit for furnace struggles is a faulty thermostat. If your thermostat is not working properly, it may not be sending the correct signals to your furnace, causing it to turn on and off at the wrong times or not at all.
To troubleshoot this issue, try replacing the batteries in your thermostat or checking the wiring to ensure it is connected properly. If the problem persists, you may need to replace your thermostat altogether.
Clogged Vents or Ducts
If your vents or ducts are clogged with dust, debris, or other obstructions, it can prevent warm air from circulating properly throughout your home. This can cause your furnace to struggle to keep your house warm, as the warm air is not able to reach all areas of your home.
To fix this issue, check your vents and ducts for any blockages and clear them out if necessary. You may also want to consider having your ducts professionally cleaned to ensure proper airflow.
Dirty or Faulty Inducer Motor
The inducer motor is responsible for drawing air into your furnace and pushing it through the heat exchanger. If this motor is dirty or faulty, it can cause your furnace to struggle to keep your house warm.
To troubleshoot this issue, check the motor for any visible dirt or debris and clean it if necessary. If the motor is damaged or not functioning properly, it may need to be replaced.
How Can I Troubleshoot My Furnace?
Now that you know some of the common causes of furnace struggles, let’s discuss some troubleshooting tips to help you get your furnace back up and running.
Check the Thermostat Settings
The first thing you should do when troubleshooting your furnace is to check the thermostat settings. Make sure it is set to “heat” and that the temperature is set higher than the current room temperature. If the thermostat is set correctly and your furnace is still not turning on, you may have a faulty thermostat that needs to be replaced.
Inspect the Air Filter
As mentioned earlier, a dirty air filter can cause your furnace to struggle to keep your house warm. Check your air filter and replace it if it is dirty. If your furnace is still not functioning properly after replacing the air filter, you may have a more serious issue that requires professional assistance.
Check the Pilot Light
If you have a gas furnace, check the pilot light to ensure it is lit. If it is not lit, follow the instructions in your furnace manual to relight it. If the pilot light continues to go out, you may have a faulty thermocouple that needs to be replaced.
Clear Any Obstructions
Check your vents and ducts for any obstructions and clear them out if necessary. This will ensure proper airflow and help your furnace distribute warm air more efficiently.
Clean the Inducer Motor
If your furnace is struggling to keep your house warm, it may be due to a dirty or faulty inducer motor. Check the motor for any visible dirt or debris and clean it if necessary. If the motor is damaged or not functioning properly, it may need to be replaced.
When Should I Call a Professional?
While some furnace issues can be easily fixed with a little troubleshooting, there are times when it’s best to call a professional. If you have tried the above troubleshooting tips and your furnace is still not functioning properly, it’s time to call in the experts.
Additionally, if you notice any strange noises, smells, or leaks coming from your furnace, it’s best to have a professional inspect it to prevent any potential damage or safety hazards.
How Can I Prevent Future Furnace Struggles?
The best way to prevent your furnace from struggling to keep your house warm is to stay on top of regular maintenance. Here are some tips to help you keep your furnace running efficiently:
- Change your air filter regularly (every 1-3 months)
- Schedule annual maintenance with a professional
- Keep your vents and ducts clean and clear of obstructions
- Keep the area around your furnace clean and free of clutter
- Consider investing in a programmable thermostat to help regulate temperature and save energy
