Could your HVAC system be making your home dusty?

Most homeowners rely on their heating and cooling system to circulate clean air. Yet it may be doing just the opposite. Much like anything else in the home, the HVAC system needs regular checkups as part of a maintenance regiment. If a home seems dustier after the AC and furnace have been running, a homeowner may need to contact an HVAC professional for an inspection. This quick checklist reveals some of the trouble spots.

Dirty Filters

Standard fiberglass furnace filters need to be replaced once a month. High quality air filters are available. In fact, air filter performance is defined by a rating system. The less expensive air filters usually get a rating between one and five for minimizing pollutants. Dustier homes may want to upgrade to air filters with a rating between five and eight to see a difference in air quality.

Dirty Vents

Air vents become a trap for airborne dust particles. Air piping through the duct system eventually forces those dust particles into the living spaces of the home. Homeowners can remove and clean the vents if there is dust bunny buildup. It’s one of the first areas an HVAC professional will check.

Duct System Gaps

The flexible piping of HVAC duct systems may, over time, develop gaps, especially between joints in the piping. The holes may be so small as to go unnoticed, which allows dirty air to spill into the home before it ever passes through the air filter. A thorough inspection, especially in the attic, will reveal to an experienced HVAC pro any openings in the duct system that need to be repaired or patched.

Not Enough Humidity

Low humidity levels in the home leave indoor air dry and dusty. HVAC systems working at their best may only filter out some of the dust particles.  If there isn’t enough moisture in the air, an HVAC professional may suggest a humidifier as an addition to the climate control system.

Simple Thermostat Adjustments

Many homeowners may not realize that typical housecleaning activities may be kicking up dust. After cleaning, a homeowner can switch the thermostat to the fan setting and open the windows. The HVAC system will blow dusty air out of the home rather than recirculate it.

If dust continues to be a problem, request an inspection of the HVAC system.  A simple cleaning and expert recommendations from an HVAC professional can help rid a home of dusty conditions.
