What Harm Can A Clogged Furnace Filter Cause?

Dec 1, 2015

Furnace filters serve a number of purposes within Lexington heating systems. When filters become clogged and are not changed regularly, they can seriously damage a furnace. Here’s what can happen to your furnace if you forget filter changes:

System Damage

Furnaces need a precise amount of airflow to work optimally. When a furnace filter becomes clogged with contaminants, it restricts airflow through the system. Without proper airflow, the furnace has to work harder to meet your household’s heating demand, stressing the system components. This can lead to breakdowns and even cause your furnace to fail entirely before its expected service life has been reached.

Higher Heating Bills

When your furnace is overworked due to restricted airflow, it will consume more energy to meet your heating demand. If you don’t change your furnace filters, expect your utility bills to be higher this season; changing furnace filters regularly can save you up to 15 percent on heating costs compared to operating your system with a clogged filter over the winter.

Air Quality Issues

They pull contaminants from the circulating air supply, helping to clean your indoor air. If the furnace filter is clogged, it won’t be able to do a good job, and more contaminants will be allowed into your living spaces.

How Often Should Filters Be Changed?

Furnace filters should be changed every one to three months, according to the specifications given by the manufacturer. In the winter when your heating system is running around the clock, you should check your filter more frequently to ensure it has not become clogged. You may need to replace your filters more frequently during periods of heavy system use.

To undo the damage caused by a clogged furnace filter, you need an expert heating repair company. Contact Climate Control of Lexington today for quality repairs.
