We all know that we can pay our auto mechanics a little now for routine service, or pay them a lot later for a major repair. The same idea holds true for your air conditioner or heat pump. If you don't service your air conditioner or heat pump regularly, you'll find yourself uncomfortable and broke.
In this article the term
air
conditioner will apply to a heat pump or a standard air conditioner.
Both benefit equally from annual service tune-ups.
An air conditioner is a very tough piece of equipment. It is engineered
to withstand all sorts of abuse and keep on running. This is great in
most respects, but it can lead to complacency about maintenance. Like a
car, air conditioners need regular tune-ups to run properly.
Without regular
maintenance an air conditioner looses about 5% of it's original
efficiency for each year of operation. This means that the 12 SEER unit
that you bought just a few years ago may be functioning like a 9 SEER
unit today! The good news is that you can recover most of that lost
efficiency through regular maintenance. Studies show that with regular
tune-ups a unit will maintain up to 95% of it's original efficiency.
This means that the cost of an annual tune-up is recovered very quickly
in savings on your monthly electric bill and reduced repair costs. A
properly serviced air conditioner will also do a better job of
dehumidifying your home.
Many Central Florida air conditioning
firms offer special prices at this time of the year. Some even offer
annual service programs that insure that you will be reminded of the
need to service the unit at the beginning of the cooling and heating
seasons.
The service check should include cleaning the condensing unit coils,
checking the amp draw of the compressor, oiling the fan motors, checking
that belts are well adjusted, and checking the system operating
pressures and temperatures against the manufacturers specifications. One
of the most important items to check is the coolant level (commonly know
as Freon) in the air conditioner. A system that is only 10% low on
coolant will cost about 20% more to operate! The Air Conditioning
Contractors of America (ACCA) recommends that coolant levels be checked
every year.
If your unit is low on coolant, and more must be added, there are new
laws governing its use. Freon is a chlorofluorocarbon (CFC) that will
damage the Earths protective ozone layer if released into the
atmosphere. The laws governing CFC's now do not allow your air
conditioner contractor to add Freon to a leaky system. They are first
required to find and fix the leak in the system. Don't ask them to
violate this law as they may loose their license if they are caught
doing this.
There are some things in addition to yearly tune-ups that you can do to
help ensure a high level of comfort and proper system operation. First,
buy good filters and change them regularly. Next, keep bushes and other
materials away from the outside unit of your air conditioner. Another
good idea is to avoid closing supply air outlets in your house. In
almost all cases, closing supply outlets is harmful to the operation of
the overall system.
All equipment, even the most reliable, needs routine maintenance.
Complicated equipment like today's air conditioners benefit in many ways
from annual service. They recover much of their lost efficiency, they
are less likely to suffer a major break down, they have a longer life
span, they increase your comfort, and they operate for less money
