Thermal Shock - Goodman AIR CONDITIONING CONDENSING UNIT 1 THRU 5 TON and GAS FIRED FURNACE Use And Care Instructions Manual

It naturally follows that on hot, "muggy" days, any additional heat and
moisture that is released within the house will place an additional burden on
the cooling system and may even be the accused of inadequate cooling.
This is where you must learn to live with the cooling system and realize its
limitations.
We have outlined in the following paragraphs several recommendations on
how to reduce heat and moisture released within the house.
COOKING
Families living in air conditioned houses have better appetites than those in
homes which are not air conditioned. Also, cooking releases a large amount
of heat and moisture. A kitchen range with all burners operating can release
more heat into the home than a two or three ton cooling unit can remove if it
did nothing else. A kitchen ventilating fan should always be running while
cooking is in process. A kitchen window should be slightly open to replace
the air the fan moves out.
MOPPING AND CLEANING
Mopping floors, washing furniture and other cleaning operations, requiring
water, will release moisture into the air as the wet surfaces dry. These
operations should be done on a cool day or at during the coolest part of a
warm day, when the full cooling capacity of the equipment is not required.
DRYING CLOTHES
Laundry, including baby clothes and lingerie, should never be dried indoors
when cooling. The water released from the clothes enters the air and then
must be removed by the cooling equipment.
Never permit an automatic clothes drier to discharge its heat and moisture
inside an air conditioned house. It will place a load upon the cooling unit that
may cause discomfort for hours. Many complaints of unsatisfactory cooling
have been traced to this one cause. Driers must be vented to the outdoors.
When venting to the outdoors, never vent close to the outdoor portion of the
Heat Pump as you will quickly fill its coils with lint.
IRONING CLOTHES
A hand iron releases heat into the air. Ironing should be done on a cool day
or late in the evening when the cooling system has reserve capacity and can
remove this extra heat without noticeable difficulty.
BATHS AND SHOWERS
Tub and shower baths release heat and moisture (steam) into the air. The
shower bath releases more than the tub bath, and of course, the longer the
shower the more released heat and moisture. A bathroom ventilating fan in
operation while the baths are being taken, will remove the heat and moisture.
Do not use a shower curtain that absorbs water – use one of plastic materials
or other non-absorbent materials.
OTHER THINGS YOU SHOULD KNOW ABOUT YOUR CENTRAL AIR
CONDITIONING
Your Heat Pump will remove odors from the house that are dust-borne
because the dust will be eliminated by the filters and the wet surfaces of the
cooling coil. Incidentally, the water that drips off the cooling coil is not
equivalent to distilled water, since it is filled with dust, germs and dust-borne
odors.
DUST, DIRT AND POLLENS
Your unit will remove most of the dirt, dust, and pollens. Many hay fever
patients report considerable relief in an air conditioned house during the
pollen season.
ENTERTAINING
Your Heat Pump was sized and designed to keep you and your family
comfortable. Unless you Dealer was told to provide cooling for an additional
15 or 20 people, your system will probably not keep this many people
comfortable on a hot day. Lowering the thermostat setting will not help,
unless it is done 3 to 4 hours before the additional people arrive.
CLEAN THE FILTERS
Filters should be cleaned monthly during air conditioning season and at least
twice during the heating season. Dirty ones affect the operation of the
equipment by reducing the amount of air that can be moved through it.
MOLD OR MILDEW
Mold or mildew should not appear on clothing or household furnishing in air
conditioned houses. If it does appear, the indoor relative humidity is probably
too high and should be investigated. Most conditions of this kind can be
traced back to an undiscovered source of moisture within the house and to
where more moisture is entering the room air than the air conditioner can
remove. This source must be located and promptly eliminated. There are
many possible sources. The most common is moisture coming from the
following: 1) Through a concrete floor that is improperly protected from soil
moisture; 2) Through the floor over a crawl space which does not have a
moisture barrier over the ground; 3) Through the floor over a damp
basement.
STALE AIR
It is recommended that the blower for air circulation be run continuously
during the operation. During mild weather when the unit does not operate for
long periods, this circulation in the air conditioned area will eliminate any
"muggy" feeling.
WINDOW COVERINGS
Windows on the east, south and west sides of the house that are not
protected from the sun on the outside, should be protected on the inside with
Venetian blinds or heavy draperies. Keep them closed or drawn when the
sun is on their side of the house. Inside protection against sun will not be as
effective as outside protection but it will help tremendously.
DOORS AND WINDOWS
Windows should remain closed throughout the cooling season. To open
them lets in warm air and often highly humid air, particularly at night. Do not
open the doors more often than necessary and then for as short a period as
possible. It usually costs more to cool a house with children that are running
in and out at frequent intervals because each time the door is opened warm
air come in.
DON'T TURN EQUIPMENT OFF AND ON
Your unit is thermostatically controlled and should be allowed to operate as
required throughout the cooling season. The thermostat will operate the unit
only as necessary to keep you comfortable and requires no help. There are
technical reasons why uninterrupted operation is the most satisfactory.

THERMAL SHOCK

The physical thermal shock to the body of a person going out of or into an air
conditioned space, so often associated with cooling during hot weather, has
been no major problem with residential air conditioning.
