Important Facts You Should
Know About Your Heat Pump

[phone] or [phone]

www.ChasRoberts.com

• During the cooling season, the heat pump operates like a conventional system.
Do Not turn the air conditioning system off. Part-time cooling is poor economy. If

•

the system is left off during the morning, the home will soak up heat and be more
difficult to cool in the afternoon. You can actually save money by letting the
thermostat determine when cooling is needed.

• During the hot, dry seasons, we recommend keeping the air conditioner blower on

continuously. The air conditioning unit cools more evenly when the blower switch is
in the ON position. The blower provides refreshing air movement and even
temperatures throughout the home. The blow er also circulates air through the filter,
which helps remove dust, lint and other pollutants more efficiently.

• Shades, drapes, shutters, or screens should be installed on windows that are

exposed to direct sunlight. Also, plant a tress or put up a canopy to protect your
windows from the direct sun.

During the heating season, the heat pump will deliver warm air , but not hot air

•

like other systems, and will operate for long periods of time. THIS IS NORMAL
Remember, air which is 80 degrees is warm air and will heat the house even though
it may feel cool to a hand, which is 98 degrees.

• During the cold weather , frost w ill accumulateon the outdoor coil. This will cause

the heat pump to go into a defrost cycle
running and you will hear the humming of the compressor and feel cool air coming
from the registers. You may also notice steam or water runoff from the outdoor unit
and hear a “whooshing” sound. THIS IS A NORM AL FUNCTION DURING THE
DEFROST CYCLE. Do not turn off the unit, change the temperature, or adjust the
thermostat during this cycle. The defrost cycle will last from 1-10 minutes depending
on the amount of ice on the coil. Then the unit will return to the heating mode.

• Night setback during the heating season is NOT recommended. The heat pump is

not designed to raise space temperatures quickly.

. During this cycle, the outdoor fan will stop

.

For cooling and heating . . . Leave your thermostat alone. When you have found

•

a temperature that you prefer , it is best to leave the thermostat at that setting.

• Clean or replace the filters frequently. Dirty filters will lower performance and

efficiency of your cooling. The filters are usually located at the return grille or at the
indoor section of your unit.

INTRODUCTION

Your Heat Pump system is a complete heating and cooling system and is
designed to give you many years of comfort. Even so, you must learn to live
with it. Any heating and cooling system has its limitations any any equipment
will function more e ffectively and be better able to give you the comfort you
expect if the family knows and follows the proper procedure.

The purpose of the OWNER’S GUIDE is to acquaint you with your Heat
Pump, with heating and cooling in general, and to suggest some procedures
which, if followed, will allow your system to function more effectively.

A Heat Pump is considered by many people to be the ult imate in efficient,
economical, modern home air condit ioning. Livi ng with a Heat pu mp can be
pleasant and comfortable, but comfort is a subjective thing. Often
misunderstandings develop as to what a Heat Pump system will do.

While reading through this booklet, it is useful to keep in mind that a Hea t
Pump is designed for efficiency of operation as well as to provide comfort. In
many respects the heating operation of a Heat Pump is quite d ifferent than
other systems.

In this booklet we will try to explain the operation of the system with respect
to how it feels to live with and also with respect to how it can be most
effectively used.

THE HEAT PUMP COOLING CYCLE

Many people condemn a home air conditioning system because it doesn’t
keep the rooms as cool and comfortable in hot, muggy weather as they think
it should. This may be unfair. Any residential cooling system has definite
limitations. It is the reverse of the heating system. Family living habits that
help the heating system are arch enemies of a cooling system. The Heat
Pump delivers heat into the room and the extraneous heat that is created
within the house form electric lights, cooking, the TV set , etc., helps to heat
the rooms. Just that much less is required from the Heat Pump in the heating
cycle.

Cooling is just the reverse. The cooling equipm ent removes heat from the
house and any extra heat released in the rooms from these same sources
will make the room air warmer and place an additional burden upon the
equipment. Further, with heating, we are primarily concerned with the
thermometer temperature and relative humidity (the amount of moisture in
the air). Relative humidity is an imp ortant factor in the comfort cooling and
the removal of moisture from the air is essential.

The effect of humidity upon comfort can be illustrated by a familiar outdoor
condition. There are days when the tempe rature is relatively high, yet it is
comfortable because the air feels “balmy”. This is because the relative
humidity is low. There are other days when the temperature is about the
same but there is discomfo rt from a “muggy” feeling and perspiration doe s
not dry on the skin. This is because the humidity is high. The same
condition can exist indoor s. The air must be both cool and relat ively dr y for
comfort.

There is nothing very mysterious about the operatio n of a cooling unit. The
theory in home air conditioning is the same as that used in the electric
refrigerator in your kitchen. Room air is drawn into the cooling unit by a fan,
first passing through a filter that removes most of the dirt, dust and pollen.

It next passes over the surface of a coil that is cooled by a refrigerant
circulating through the inside of the co il. Here the temperature of the air is
reduced and then discharged through ducts and registers into the rooms.

When this air passes through the coil, it also loses some of its moisture which
collects upon the coil surfaces in the form of water and is wasted to the sewer
by a condensate drain. Your unit is designed to remove the maximum
amount of heat and moisture: however , you should never lose sight of the
fact that there are definite limits on its capacity to do either.

Since the purpose of the cooling is to remove heat from the inside of the
house, the first step should be to keep as much heat as possible from
entering the house. Heat enter s the house through wall s heated by outdoor
air and the sun. It comes in through the ceiling from the roof or attic above.

When the temperature outside is 90 degrees, it is ve ry possible fo r your attic
temperature to reach 130 degrees if it i s not properly ve ntilated. You should
have cross ventilation to remove the excessive heat. An attic fan may be
added at one end of the attic to gi ve the ulti mate in at tic ventil ation. The fan
may be thermostatically controlled, or it may be manually controlled by you.

Glass areas exposed to the sun are responsible for a very substantial amount
of the heat that enters a house. The sun no t only heat s the g lass but al so all
the surfaces indoors that it shines upon. The most effective way to eli mina te
this heat is to keep the sun off the glass area and windows. A roof o verhang
of two or three feet on the south side of the house will e ffectively shade the
windows on that side. Exterior awnings and sun shades will offer partial
protection on the east and west sides, and the fewer the window on these two
sides of the house the better. Tall shrubs and plantings, a vine covered trellis
or a garden wall are particula rly effective. Scr een shades, Venetian blinds
and heavy draperies will al so help. A few trees that shade the house ar e of
value.

Some of these protective methods will be difficult to provide on an existing
house, be every one that is practical should be used for comfort and for
operating economy. As a matter of information, even the orientation of the
house on the lot can mean much to the cooling system.

A temperature of seventy-six to seventy-eight degree s is preferred by most
people. You may select a lower temperature setting if you wish and you will
probably have that temperature a good port ion of the time . However, do not
be disappointed if the temperature gets a few degrees warmer during the
very hot afternoon. Most residential systems are designed for a maximum
cooling that will maintain the indoor temperature 30 degrees below the
normal outdoor temperature and they cannot do much better than that.

We have already learned that the fun ctio n of the air condit ioning s ystem is t o
remove both heat and moistur e f ro m the ho m e. When it is extremely ho t and
“muggy” any residential air conditioning system has to work hard to obtain the
differential between indoor and outdoor temperature mentioned in the
paragraph above.

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 parag raphs several recommendations on
how to reduce heat and moisture released within the house.

Families li ving in air conditioned houses have be tter 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 relea se
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 progress. A kitchen window should be slightly open to repla ce
the air the fan moves out. Mopping floors, washing furniture and other
cleaning operations, requiring water, will release mo isture 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 capa city of the
equipment is not required.

Laundry, including baby clothes and lingerie, shou ld 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 cl othes drier to discharge its heat and moisture
inside an air conditioned house. It will place a load upon the cooli ng unit that
may cause discomfort for hours. Many complaints of unsatisfactory cooling
have been traced to this one cause. Dr iers must be vented to the outdoors.
When venting to the outdoors, never vent close to the outdoor por tion of the
Heat Pump as you will quickly fill its coils with lint.

A hand iron or a mangle releases heat into the air, the difference between the
two, only being the amount of heat relea sed. 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.

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 ventil ating fan in
operation while the baths ar e be ing ta ken, will rem ove the heat and mo ist u r e.
Do not use a shower curtain that absorbs water – use one of plastic materials
or other non-absorbent materials.

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 fille d with dust, germs and du st-borne
odors.

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.

Filters should be cleaned per iodically. Dirt y ones affect the operation of the
equipment by reducing the amount of air that can be moved through it.

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 sour ce 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 elimina ted. 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.
It is recommended that the blower for air circulation be run continuously

during the operation. During mild weather when t he unit does not operate for
long periods, this circulation in the air conditioned area will eliminate any
“muggy” feeling.

Windows on the east, south and west sides of the house that are not
protected from the sun on the out sid e, shou ld be prote cted on the in si de wi th
Venetian blinds or heavy draperies. Keep them clos ed 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.

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 ne cessary and then fo r as sho rt a period as
possible. It usually costs mor e to cool a house w ith ch ildr en that are running
in and out at frequent intervals because each time the door is opened warm
air come in.

Your unit is thermostatically controlle d and should be allowed to operate as
required throughout the cooling sea son. The thermostat will operate the unit
only as necessary to keep you comfortab le and requires no help. There are
technical reasons why uninterrupted operation is the most satisfactory.

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. There appears to be
no dangerous physical shock to a normally healthy person entering or leaving
an air conditioned apace, although the change may be temporarily
unpleasant. This however, may not be the case with persons in ill health.
With such persons the greater the difference in temperature between the air
conditioned space and the outdoors, the greater the reacti on or discomfort
will be. Mothers with smal l children who go in and out of doors frequently
have avoided the possibility of this by maintaining a slightly higher
temperature indoors.

You will learn that there are many more things that you Heat Pump will do for
you which we have not mentioned. Many of these you will recognize when
they present themselves. If you will remember to minimize the release of
heat and moisture indoors, especially on hot “muggy” days, you will r ealize
maximum comfort for your air conditioning system.

Folks who live in air conditioned homes generally eat better, stay at home
more, and are more amiable, along with countless other blessing s that only
domestic air conditioning can bring.

THE HEAT PUMP HEATING CYCLE

There are certain preparations that must be made for the heating season.
The same as for the cooling season.

For instance, close the attic ventila tors to keep out cold winds. Be sure that
storm windows indoors are in position to eliminate any drafts that might
occur.

All the family li ving habits that were curtailed during the cooling season, do
not have to be watched so closely in the heating season. On the contrary,
any activity that wil l give off heat or moisture will be beneficial as long as it
has no direct bearing on the thermostat.

To obtain the Heating Cycle, move the System Switch from “Cool” to “Heat”.
Here again, the most desirable comfort seeing at the thermostat that is
satisfactory to you should be maintained throughout the heating season.
Turning the thermostat up and down at frequent intervals will give you
unsatisfactory operation, poor comfort conditions as well as unbalanced
conditions.

The operation of this portion of the thermostat is a lso automatic in that when
the temperature increase is desired, the Heat Pump will turn on
automatically. Here again, it is our reco mmendation that the fan switch be
allowed to operate in the ON position rather than cycle with heating
requirements. This will eliminate stratification of air; it will maintain a better
temperature gradient between floor and ceilin gs, and generall y will make the
thermostat much more sensitive.

There are a number of points in the operation of the Heat Pump wh ich do
differ considerably from other heating systems. While these points are not
necessarily bad, it is useful to understand how the system should operate for
your own peace of mind.

AIR DELIVERY . . . The air-volume requirement of a Heat Pump is
considerably more than that of a gas or oil f ire heating system. The greater
air-volume is needed for maxi mum efficiency of operat ion. The fact that so
much air-volume is required leads to several importan t considerations. The
temperature of the air delivered is lower than w ith other systems. At some
time, the Heat Pump will be delivering air at a temperature just over 80
degrees. Even though this temperature is war m enough to heat your house,
it may feel cool to the touch. It is very important that the system be allowed
to move the full air-volume for which it is designed. This means that registers
should never be blocked with furniture or pict ures. It means that the filters
must be kept clean so as not to restrict air delivery. It also means that you
should resist the impulse to close off registers, even in occupied rooms.

OPERATION . . . The Heat Pump system is designed to run more of the

time than other systems. This does not mean that is is wasting power.
On the contrary, it conserves power by operating on a smoother
temperature cycle. It also means your tem perature stays a little more
constant, and your home a little more comfo rtabl e. In many ca ses when
the outdoor temperature drops to the 20’s o r 30’s or below, the unit runs
constantly. Don’t worry, this is nor mal and it won’t make your electric
bill go out of sight. At the same time this happens, the indoor
temperature may drop one or two degree s below the point where your
thermostat is set. The system could be designed so this would not
happen, but if so it would not be as e ffic ient . If the lowe red temper ature
is uncomfortable, you may want to increase the thermostat setting for a
while. When the temperature comes back up outside, the effect will go
away again.

NIGHT SET-BACK . . . Currently, it is quite common to reduce the
temperature setting on a heating syste m at night and then return it to
normal in the morning. This can be done either manually or with a
special thermostat. However, it is n ot recommended tha t a Heat Pump
system be set-back. It appears fro m what is now known, that nigh t set­back of a Heat Pump actually costs you money rather than saving it.

DEFROST . . . The no rmal heating operat ion of a Heat Pump results in
a coating of frost accumulating on the outdoor unit. Periodically, the unit
will automatically defrost itself. When the unit goes into defrost a
“whooshing” sound is audible if you happen to be near the unit. (Th is
same sound can be heard when the unit shuts off during heating
operation.) The sound is normal and should be no cause for ala rm . It is
also normal for steam to come off the outdoor coil dur ing the defrost.
Defrost is completely automatic and is controlled by sensors in the
outdoor unit.

performances of operation of your Heat Pump system, contact Chas
Roberts Air Conditioning. They a re experts in heating and cooli ng and
will be happy to assist you.

SERVICE HINTS AND POINTS TO CHECK IF YOUR UNIT B ECO ME S
INOPERATIVE:

1. CHECK FUSES

Use only Fusetron or Fusestat type fuses. On cartridge types, some
type of fuse tester should be used. These fuses mi ght be found in the
optional disconnect attached to the unit or wall ad jacent to the outdoor
unit. They also might be found in the main electric panel inside the
building.

2. DIRTY FILTERS

When operating on the cooling cycle and the filte rs are dirty, your unit
may short cycle (go of f and on) and f rost may form on the in door coil a s
well as the large line between the outdoor unit and the coil instal led in
the indoor Air Handler.

When operating on the heating cycle, and the filters are dirty, the
compressor will be running at an abnormally high temperature. This can
cause the compressor to shut-off.

Clean or replace the filters if they are the disposable type. The filter can
be found contained in the Air Handler filter rack or box adjacent to or
under the Air Handler or in a return air filter grille.

3. INDOOR EVAPORATOR COIL COVERED WITH ICE OR NO
BLOWER ACTION

Check for broken blower belt or defective blower motor.

4. CLOGGED COIL IN OUTDOOR UNIT (SUMMER)

Grass cutting, leaves, dirt and dust, lint f rom clothes dryer, fall-of f from
trees, can be drawn into the coil by movem ent of the air. A clogged
condenser coil will lower the efficiency of your unit and could cause
damage to the condenser. Damage of this type i s not covered by the
Warranty. Use a brush to remove debris from the coil.

UNDER NO CIRCUMSTANCES SHOULD THE THERMOSTAT BE
TURNED OFF AND THEN IMMEDIATELY TURNED ON AGAIN. THIS
QUICK CYCLING CAN AND WILL BURN OUT CONTROLS IN
STARTING CIRCUITS AND ALSO IN THE COMPRESSOR. IF THE
THERMOSTAT IS TURNED OFF, DO NOT TURN BACK ON FOR AT
LEAST THREE (3) MINUTES.

OPERATING THE THERMOSTAT:

HEATING CYCLE:

Switch the system lever to HEAT . Then set the Temperature Selection
Lever to the desired temperature.

COOLING CYCLE:

Switch the system lever to COOL.

FAN CONTROL:

Your thermostat has a Fan Selection Switch which will allow you to run
the fan continuously or cycle it automaticall y with the heating or cool ing
system. Switch the lever to ON for continuous operation and to AUTO
for automatic cycling. For maximum comfort satisfaction, constant fan
operation throughout the year is recommended.
