Part of responsible homeownership includes, of course, regular home maintenance. And there are some tasks that, if deferred, can lead to a home system that’s inefficient and overworked, which can result in problems and expenses. One such task is changing the filter of the home’s HVAC system. It’s simple and inexpensive, and taking care of it at least every three months can mean the difference between optimum comfort and avoidable repairs.
Most
homes have some sort of furnace or heat pump, and many of those homes
(especially newer ones) have combined heating, ventilation and air-conditioning
or HVAC systems. Each type uses some type of air filter or screen to prevent
larger airborne particles (up to 40 microns) from entering the system and
clogging sensitive machinery. A system that has a dirty filter can suffer from
pressure drop, which can lead to reduced air flow, or “blow-out,” resulting in
no air infiltration at all. Any of these conditions can cause the system to
work harder to keep the home warm or cool (depending on the season and the
setting). And any mechanical component that has to work harder to run
efficiently puts undue stress on the whole system, which can lead to premature
failure, resulting in repair or replacement.
Also,
a dirty filter that’s exposed to condensation can become damp, which can lead
to mold growth that can be spread throughout the home by the HVAC system. This
can lead to serious health consequences, not to mention a compromised unit that
will likely require servicing and may require replacement, depending on the
severity of the moisture problem.
Most
HVAC and furnace filters are disposable, made of biodegradable paper or similar
media, and shaped in cells, screens or fins designed to trap as much airborne
debris as possible. Filters can typically be purchased in economical
multi-packs, and there are many types that will fit different models of
furnace/HVAC units. It’s important to use the appropriate filter for your unit;
using the wrong filter that doesn’t fit the unit properly can create the same
types of problems as having a dirty filter. Your HVAC installer can show you
where the filter goes and how to remove the old one and install a new one. Your
radon testing
inspection in Gaithersburg md unit may also have an affixed label with directions for easy
filter replacement.
Your
HVAC or furnace technician should service your unit once a year. Because a
furnace/HVAC unit contains moving parts, it’s important that belts are not
cracked and dry, ventilation ductwork is not gapped, cracked or rusted, and
components, such as coils and fans, are clog-free and adequately lubricated for
unimpeded operation. This sort of evaluation is best left to the professional,
unless the homeowner has had the appropriate training.
The
filter of the unit, especially if it’s an HVAC unit that will tend to get
nearly year-round use, should be changed by the homeowner at least every three
months, but possibly more often.
