Dirty air filters

One of the most common reasons why a furnace may struggle to keep up with demand is due to dirty air filters. When air filters become clogged with dirt and debris, it becomes difficult for air to pass through, which can cause your furnace to work harder than it needs to. This can cause your furnace to overheat and potentially even shut down. Regularly changing your air filters can help prevent this from happening and keep your furnace running efficiently.

Thermostat issues

If your thermostat is not working properly, it can cause your furnace to turn on and off more frequently than it should. This can cause your furnace to struggle to keep up with demand and may even cause it to break down. Make sure to check your thermostat regularly to ensure that it is working properly and set to the appropriate temperature.

Duct problems

If you have leaky or blocked ducts, it can cause your furnace to struggle to keep up with demand. Leaky ducts can cause heated air to escape, while blocked ducts can prevent heated air from reaching certain parts of your home. Make sure to regularly inspect your ducts for any issues and have them repaired or cleaned as needed.

By addressing these common issues, you may be able to improve your furnace’s ability to keep up with demand and potentially extend its lifespan. However, if these problems persist or your furnace is nearing the end of its lifespan, it may be time to consider a replacement.

3. The importance of regular furnace maintenance to extend its life

Regular Furnace Maintenance is Crucial

Regular maintenance of your furnace can help prevent sudden breakdowns and prolong its lifespan. A well-maintained furnace operates efficiently, saving you both energy and money.
