We’re already in the middle of winter in Harford County, so if you haven’t changed your furnace filter since fall, it’s definitely time. A clogged furnace can wreak havoc on your HVAC system, your comfort, and your bank account, so make it a priority this weekend to get a new furnace filter!
Why should I change my furnace filter?
The forced air that flows from your furnace into your living space must first pass through the furnace filter. Here, particles such as dead skin cells, dust, pet dander, and other debris are removed from the air stream that travels through your duct work. As the filter removes these particles, it starts to get clogged up and eventually is unable to trap any debris. Here are the reasons that’s not good:
It causes stress on your furnace. Once the furnace is clogged, air can’t flow as freely, so your furnace has to work harder to heat your home to the thermostat’s designated temperature. More stress on your furnace means earlier breakdowns and a shorter life.
It increases your energy bill. With decreased airflow, your furnace will continue to run in order to heat your home. The longer your furnace runs, the more you’ll be charged for energy use.
It’s bad for your indoor air quality. The Environmental Protection Agency estimates that the air inside our homes can be up to five times more polluted than the air we breathe outdoors. A clogged furnace filter doesn’t trap allergens, mold spores and bacteria like a new one can, making it more likely that you’re breathing them in. This can be especially bad for those who suffer from allergies and asthma.
How often should I change my air filter?
A good rule of thumb for a basic one-inch filter is to change it every other month — and every month if you have a shedding animal. If you or your family member has allergies or asthma, ask your One Hour technician about the best air filter for allergies. We can recommend a furnace filter with a higher MERV rating (13 or above) that traps the tiniest particles including viruses.
