Important Home Maintenance Tips
Just like your car, your home comfort system needs routine
maintenance to keep it running at its best. Without regular servicing, heating
and cooling systems waste energy and are more likely to break down. But with the
proper attention, they can keep you comfortable year-round.
Below are some basic tips to keep your system running
efficiently.
Blowers
Tuning up the distribution side of a forced-air system starts with the blower.
The axle should be lubricated; blades cleaned and lower motor checked to insure
the unit isn't being overloaded. The fan belt should be adjusted so it deflects
no more than an inch when pressed. Every accessible joint in the ductwork should
be sealed with mastic or UL-approved duct tapes. Any ducts that run outside the
heated space should be insulated. On a hot-water system, the expansion tank
should be drained, the circulating pump cleaned and lubricated and air bled out
of the radiators.
Thermostats
While thermostats rarely fail outright, they can degrade over time as mechanical
parts stick or lose their calibration. Older units will send faulty signals if
they've been knocked out of level or have dirty switches. To recalibrate an
older unit, use a wrench to adjust the nut on the back of the mercury switch
until it turns the system on and, using a room thermometer, set it to the
correct temperature. Modern electronic thermostats, sealed at the factory to
keep out dust and grime, rarely need adjusting. However, whether your thermostat
is old or young, the hole where the thermostat wire comes through the wall needs
to be caulked or a draft could trick it into thinking the room is warmer or
colder than it really is.
Humidifiers
A neglected in-duct humidifier can breed mildew and bacteria, not to mention add
too much moisture to a house. A common mistake with humidifiers is leaving them
on after the heating season ends. Don't forget to pull the plug, shut the water
valve and drain the unit. A unit with a water reservoir should be drained and
cleaned with white vinegar, a mix of one part chlorine bleach to eight parts
water or muriatic acid. Mist-type
humidifiers
also require regular cleaning to remove mineral deposits.
Filters
Most houses with forced-air furnaces have a standard furnace filter made from
loosely woven spun-glass fibers designed to keep it and its ductwork clean.
Unfortunately, they don't improve indoor air quality. That takes a media filter,
which sits in between the main return duct and the blower cabinet. Made of a
deeply pleated, paper-like material, media filters are at least seven times
better than a standard filter at removing dust and other particles. An upgrade
to a pleated media filter will cleanse the air of everything from insecticide
dust to flu viruses.
Compressed, media filters are usually no wider than six inches, but the pleated
material can cover up to 75 square feet when stretched out. This increased area
of filtration accounts for the filter's long life, which can exceed two years.
The only drawback to a media filter is its tight weave, which can restrict a
furnace's ability to blow air through the house. To insure a steady, strong
airflow through the house, choose a filter that matches your blower's capacity.
