To keep your air conditioner running well and your indoor air clean, change your equipment’s filter regularly, urges Tom Eppers, co-owner, Dowe & Wagner, a heating, ventilation, and air-conditioning (HVAC) company serving residential and commercial customers in Illinois and Wisconsin.
Eppers says many HVAC breakdowns are caused by dirty filters, which become clogged and can’t trap debris thoroughly. Other key filter facts include:
1. Filters can be inexpensive and easy to change. A clean filter can remove airborne particles before they can damage the HVAC unit’s blower motor, which can be a costly repair. When free of debris, a system can operate much more smoothly, which means economically, too.
2. A clean filter traps a greater number of pollutants to improve air quality. This helps family members suffering from lung or breathing issues, such as asthma or allergies.
3. Filters are available in different sizes and models, to fit a homeowner’s goals. For homeowners wanting extra filtration, Eppers recommends a whole-house filtration system, which can be incorporated into almost any HVAC system to capture more contaminants.
Your HVAC unit’s owner’s manual details the filter’s correct size, location, and instructions on how to change it, which is usually a simple process of sliding the old one out monthly, and the new one in the slot. Arrows or diagrams on the filter indicate proper placement.
Filters may be disposable with cardboard frames, or reusable with more sturdy plastic frames. Replacement filters are available at hardware and home improvement stores for an average cost of about $25.
Before changing the filter, experts advise turning off the furnace. To ensure safety, shut off the switch at the fuse box, the circuit breaker, or the furnace cutoff switch.
