The days are getting shorter and the nights getting cooler, and even though it’s not quite winter here in the Kansas City area, we’ve been getting several phone calls from homeowners who are turning their furnaces on and having some major issues. Major repairs often can be prevented by one simple fix, changing your furnace filter.
During the cooler months when your furnace is running, we suggest changing your furnace filter every 4-6 weeks. By checking your air filter before you turn your furnace on, you can prevent these potential dangers caused by a dirty furnace filter.
Long-term Damage of Your HVAC Unit
A dirty filter is the most common reason a heating and air conditioning system breaks down. When dirt accumulates, the air won’t flow through, causing your furnace motor to work harder. As a result, the unit could overheat. If your system is older and you don’t regularly change the filters, you may have to replace the whole HVAC unit which is far more expensive than replacing a dirty air filter.
Increased Energy Costs
When your furnace is running with a dirty filter, it has to work harder, which in return, results in skyrocketing energy bills. If your unit seems to be running constantly but the air temperature within your home is inconsistent, this could be a sign that your filter is dirty.

Poor Air Quality
Anyone with allergies or asthma knows how important it is to have healthy, clean air. Dirty furnace filters deteriorate air quality and aggravate symptoms. Additionally, if filters are not replaced regularly, they are unable to pick up airborne pollutants such as allergens, dust mites, and pollen. Consequently, this results in health problems such as the common cold, influenza, headaches, allergic reactions, breathing difficulties, fatigue, dizziness and even nausea. Replacing the filters regularly is also important if you have pets. Over time, pet dander accumulates in the system and spreads throughout the house.
The entire HVAC unit can become polluted when using a clogged filter. This leads to extra repairs, services, and parts. By changing your furnace filter monthly, especially during winter and summer months when it is most in use, you will save money, improve your indoor air quality, extend the life of your HVAC unit, and decrease the amount of energy used.
