Dottie,
As a hvac professional, let me describe it to you this way..........
Your system is a workiing moving mechanical device that is affected by
dust, temperature, pressure, wear, refrigerant, voltage imbalance,
etc, etc. If you read your owners manual it will tell you most likely
that not only is regular maintenance recommended but probably
required. I would recommend it. Do you have to? No, you dont have to
do anything. Properly serviced (stressing PROPERLY) your unit will
most likely give you years of trouble free service and always
operating at its peak efficiency.
If you did NOT purchase a 5 or 10 yr parts AND LABOR warranty, you can
still do it now.I HIGHLY recommend it on any hvac equipment. Just call
your dealer. Hell, even I can sell you one. You pay the regular price
but you lose the time already elapsed since you had it installed. You
may be suprised when you see the repair bill on an out of warranty
motor or major componet. You have your car serviced regularly, dont
you?

My furnace (a Tempstar medium efficiency unit) warranty does not
require the selling dealer to service it at all (thank goodness,
because the dealer went T.U. 1 1/2 years after I bought it) - but the
warranty is not much good either. The DC inductor motor/fan got noisy
at 2 years. Still under warranty. Because the dealer is no longer in
business, I would have had to pay full price for the OEM part, AND
installation, then the repairing dealer would "talk to" Tempstar and I
may or may not get anywhere from 0 to $600 back, sometime in the next
ten years. Not only that, the required part was not in stock anywhere
in Canada - and they were uncertain if one could be found in the USA.
A replacement FASCO motor/fan was available out of the US for about
$175 - so I pulled the fan unit myself and brazed the fan wheel to the
hub (it was loose, as evidenced by "fretting" and rust stains coming
out of the poorly crimped joint). It has been perfectly quiet, and
running with no problems for close to 2 years now. If I find a spare
at a reasonable price I will buy it. If not, it's working fine now.

As for the AC, mine is over 35 years old now and has never been
touched. (no freon added). I did have it checked once about 15 years
ago. If and when it fails, replacement will be cheaper than repair. I
doubt half the parts are still available for it.

There's really not much that can go wrong with an AC unit and the things
that can go wrong won't be helped by "maintenance." That is, there is no
maintenance that can be done on a compressor, relay, or fan motor. When they
fail, you replace them.

If the unit quits cooling, have a repairman find the leak, fix it, and add
coolant. That's really all than can be done.

There ARE two things that fall into the maintenance regime, and both of
those you can do yourself.

The filters need changing at regular intervals and the outside coil needs
periodic cleaning.

We always recommend cleaning a straight AC condensing unit
(the outside part) once a year. A heat pump, twice a year.
We always admonish the homeowner to make sure that the AC
is turned off whenever the grass is being cut anywhere near
the outside unit. Why? The condensing unit will suck up all
the dust and grass clippings in the air around it. The dirt
will clog up the fins and cause the compressor to overheat
which will damage it. Trane produces some fine equipment
and yours may be equipped with high and low pressure cutout
switches which will protect a unit from overheating due to
the fins being clogged and damaged caused by a loss of freon.
I've seen too many condensing units damaged by a homeowner
who decided to clean the AC with the water hose nozzle set
to KILL. This will bend and flatten the aluminum fins which
will block the airflow and cause overheating. If you can find
a good service company in your area, talk to them about a
service contract where they will come out at least once a year
to clean and inspect your HVAC system.

I guess I will side with HeyBub rather than with Bubba.

A/Cs either work or they don't; not much preventive maintenance; except
keeping the fins clean.
Furnaces are another story. They do need to be cleaned.

All I can say is you are NOT in my shoes. I would be happy to show you
the amount of money I have taken in over the past 25 years due to
repairs on units from lack of maintenance. This doesnt even take into
account the amount of money wasted in energy use. A/C's are no
different.

We have an educational moment at hand!

What excessive expense could one expect from the lack of what periodic
maintenance done by a professional?

Scaring people again I see. Its funny how my Lennox installer, a 50
man co. said "you dont need yearly maintenance" for heat as he knows
my systems environment. Nor did my certified Weil McLain boiler dealer-
installer. On the other hand I have a 4" air filter that keeps coils,
blower, and heat exchanger clean. Some units run with crappy, cheap,
poor fitting 1" filters in dusty condition do need yearly maintenance,
some coils mold up. After 1 year its a good idea, then it might be a 1
- 3 yr schedule depending on its present condition. If you listened to
every repair guy for all building-control-havc systems you have, you
would be wasting alot every year for them to have a look see, for a
buck. For AC, I have a yearly service contract, but everything else
has a schedule based on past performance and its not yearly, its based
on its need. And it doesnt Violate my warranty as bubba scares folks
into believing. Bubba will sell you a warranty, id pass.

I commend you for for having the good sense to get the best

to pay the most attention to. What brand filter are you using?
I have a customer who has an AprilAire Space-Gard 2200 that
does a very good job at keeping things clean. Unfortunately,
it's hard to get people to spend money on superior filtration
when they're shopping price for a new HVAC system.

It's not just the evaporator that gets clogged up. For

Actualy check your spaceguard and AC coil, I have 2 at different
locations and found a non positive seal occuring at the top due to
lack of a weather stripping that Space Guard rep could not fix. It
allowed my spacepack to get dirty at the top of the coil needing
cleaning until I got thin foam weather striping to get a 100% air
seal. Air Bear seals air tight, buy my 2 space guards didnt until I
worked on them. They have great media, but poor filter holder to
housing seal. I needed yearly coil cleaning until I retrofitted the
weatherstripping, now its clean 3 years.

determine what is needed. Nobody who drives 10000 miles a year needs
an annual full car check up as bubby thinks.

Good response! But I'm still confused.

Suppose a professional detects an increased amperage due to impending
compressor failure. Where is the savings due to be had by this early
detection?

Admittedly, replacing the compressor now (instead of six months down the
line) will result in lower electric bills. Is that what you had in mind?

Because there is a reason for the amperage difference. Is it because
of the cap going bad, loose connections, low or overcharged
refrigerant, clogged coils, dirty filter, etc? Any of these things can
cause your compressor to fail. If you catch them before the compressor
fails you fix the problem and save a bucket of money because you did
not have to replace the compressor when it's 105 degrees out, you're
sweating your ass off and have to wait a week for a part.

Just proving you Hacks are hacks, and only money motivated.

I think it's best to get the AC clean and check in the spring, right when
the warm weather starts, but before it's hot. That way the guy can check
with fairly typical outdoor temperatures.

Many units have a shut down switch in case of low freon. You should also
notice the lack of cooling. Many Trane units I've serviced, it's hard to
tell if the outdoor unit needs cleaning. Ask them to be sure to spray on the
cleaning chemicals, let them soak, and rinse off with the garden hose. Even
if it "looks clean".
