When is it time to upgrade?
(source:epinions.com)
Rising fuel costs are
making it mandatory for home owners to better manage the efficiency of their
central system. The most recent advances in SEER performance and the
increasing awareness of proper duct balancing and cleaning are providing
consumers with more tools. But, what should you consider before you buy?
Here are some helpful points:
You should consider
buying one during the spring "rebate" season if your current unit
is old and you are worried about its reliability. A new unit can also be a
good idea if your old unit has an 8-EER or less. During the summer, units are
expensive and have limited availability. However, if your old AC unit is
broken then you have no choice.
Most companies have rebates in the March-June timeframe and the new, more
efficient models appear in the spring. Although you can get some bargains
after the season, a warm summer can leave pretty slim pickings. Don't forget
that your warrantee starts on the day you buy it, so buying in the fall
effectively shortens the warrantee.
Air conditioners come in four main types: window units, through the wall
units, portable units and whole house/central air units. Window units come in
three main flavors: double-hung windows, sliding windows and casement
windows.
Window units will usually convert between types with special hardware,
which is often included. Small through the wall units will often convert into
window units. Large through the wall, and central air units usually require
professional installation, which adds to the cost.
You should expect the unit to have an adjustable thermostat, at least two
cooling speeds, two fan speeds and an energy efficient setting, which stops
the fan when the unit is not cooling. The unit should have an adjustable
vent, which allows you to aim the cool air, and an exhaust vent setting
allowing fresh air to be introduced from outside. The filter should be easily
accessible for removal and cleaning. You want a manufacturer's warrantee for
at least 5 years, with full replacement for at least 1 year.
Some of the newer units have an electrostatic filter available either
standard or as an option. This filter will remove extremely small particles
from the air. This is a super feature for people with allergies.
