Central Air Conditioning

How it works to  
keep you comfortable.  
Your central air conditioner is designed to work with your  
indoor furnace and give you years of dependable service.  
Your new central air conditioning system is designed to give you years of comfort  
and dependable performance. It will cool every room in your house — and use less  
energy to do it than ever before.  
The reason: we’ve improved the compressor in many of our units. Now it pumps the  
heat out of your home more efficiently. And we’ve made our new coils bigger, so they  
dispose of this heat more quickly.  
Your central air conditioner filters and dehumidifies.  
As the Trane air conditioner circulates the air, it also filters it.The result: less  
housework for you, and a cleaner house year ’round.The air conditioner also  
extracts excess moisture from the air inside your home, thus helping to control  
humidity in muggy summer months.  
At the end of the cooling season, it’s easy to deactivate the air conditioner. Simply  
move the thermostat switch to HEAT. Now the furnace takes over. And the blower  
that circulated cool air in the summer now circulates warm air to keep you  
comfortable during the cold months.  
Easy maintenance reduces  
electricity use.  
Both methods are quick and easy — and  
guaranteed to improve the performance of your  
system.  
A clean filter saves money.  
When the air conditioner circulates and filters the  
air in your home, dust and dirt particles build up  
on the filter. Excessive accumulation can block  
the airflow, forcing the unit to work harder to  
maintain desired temperatures.  
How to remove your filter.  
Ask your Trane dealer where the filter is located  
when he installs your system. In most cases there  
will be one filter behind the bottom panel of your  
indoor unit.  
And the harder your unit has to work, the more  
energy it uses. So you pay more any time your  
system is running with a dirty filter.  
Help ensure top efficiency by  
Cleaning or replacing the filter  
once a month.  
When replacing your furnace filters, always use  
the same size and type that was originally  
supplied. Filters are available from your dealer.  
Clean it twice a month during seasons when the  
unit runs more often.  
You can leave the filter in the frame and vacuum  
it. Or you can take it out of the frame and wash it  
like a sponge.  
Where disposable filters are used, they must be  
replaced every month with the same size as  
originally supplied.

sure that nothing is stacked against the sides of  
the unit or draped over it.  
But your unit may have two filters.  
In either case, removing the filter is easy. See the  
owners manual furnished with the indoor unit.  
Just be sure to replace it with the arrows on it  
pointing in the direction of the airflow.  
Making sure that your outdoor unit is kept clear at  
all times helps it work at peak efficiency. And that  
helps you save money.  
Cut operating costs by keeping outdoor unit  
clear of the debris, leaves and shrubbery.  
CAUTION:Whenever your house is to be  
vacant, arrange to have someone inspect  
your house for proper temperature.This is  
very important in below freezing weather.  
If for any reason your heating system  
should fail to operate, damage could  
result, such as frozen water pipes.  
Efficient operation of your air conditioner depends  
on the free flow of air over the coil. Anything that  
blocks the airflow, causes the compressor to work  
harder to move the warm air out of your house.  
To avoid overworking your unit, do not plant  
flowers or shrubbery right next to it. Also, make

setback periods each day, plus weekend and  
vacation programs. It saves energy while it keeps  
you comfortable day or night.  
Here’s how: place the system switch on COOL, and  
the fan switch on AUTO.Then set the temperature  
by using the indicator on the thermostat* control.  
If the main power is ever disconnected for more  
than three hours, turn off the thermostat.Then wait  
for at least three more hours after power has been  
restored before turning the thermostat back on.  
Failure to follow this procedure could result in  
damage to your system.  
Let the thermostat do its job.  
Your system will perform most efficiently when you  
let the thermostat control it.Turning the system on  
and off manually is usually much less efficient. So  
let the thermostat do its job.You’ll be sure to save  
energy.  
CAUTION: If unit is not operational during the  
cold weather months, provisions must be taken  
to prevent freeze-up of all water pipes and  
water receptacles.  
We recommend keeping the temperature setting at  
78°F for cooling, 68°F for heating. But you can  
select the temperature you’re most comfortable with.  
Now your system will cool your house whenever the  
indoor temperature climbs above the thermostat  
setting. It will shut off when the desired room  
temperature is reached.  
How to help reduce summer  
humidity.  
The point is, once you’ve set the thermostat, keep  
subsequent adjustments to a minimum.  
In summer, your air conditioner does more than  
cool the air. It also helps remove the excess  
moisture that can make the inside of your home  
feel muggy.When removing this moisture your  
system must work harder than when simply cooling  
the air.  
In winter, it works the same way.When the system  
switch is on HEAT, the system will operate  
whenever the room temperature falls below the  
temperature setting. Once the desired temperature  
is reached, the system will shut off.  
At all other times, let the thermostat keep you  
comfortable. And keep energy bills down.  
Don’t waste money heating and  
cooling when you don’t need to.  
Carefully read the accompanying thermostat  
manual for operating instructions.

moderate — don’t let the air conditioner run unnec-

And raise it to 85°F in summer.Then when you  
return — or when temperature conditions dictate —  
you can reset the system and it will immediately  
begin making your home comfortable again.

7. Remember that by increasing the glass area,  
you increase the amount of heat added in  
summer and lost in winter.  
Insulation  
1. Make sure your home is properly insulated.  
This is the single most important step in  
conserving energy.Thermal insulation should  
be specified in terms of thermal resistance  
(R-values). R-30 (10") is recommended for  
ceilings, R-11 (3½") for exterior walls and  
floors over unheated areas. In colder  
3. Cut heat transfer through your windows by  
40 to 50% with double glazing (two panes of  
glass separated by a sealed air space).  
8. Keep the overhead door of an attached  
garage closed.This will block cold winds from  
infiltrating the connecting door between the  
house and garage.  
4. Use wood or metal-frame storm windows  
even if single-glazed windows are high  
quality.The extra layer of glass and the layer  
of still air will cut heat transfer considerably.  
9. Make sure fireplaces have tight-fitting  
dampers which can be closed when the  
fireplace is not in use.  
climates, consider additional insulation.  
2. Infiltration of humid outside air is your heating  
and cooling system’s worst enemy — it could  
account for 15 to 30% of air conditioning  
energy requirements. Find the places where  
air can sneak into the home and plug them

bucket of water out of the bottom of the tank  
as it may be full of sediment.

11. Locate the thermostat on an inside wall away  
from windows and doors.  
24. Add an extra layer of protection with a water  
heater insulation kit. It will keep the heat from  
being lost through the walls of your tank.  
18. During moderate weather, don’t use the air  
conditioner unnecessarily.  
12. Set the thermostat as low as comfort permits.  
Each degree over 68°F can add 3% to the  
amount of energy needed for heating.  
19. Draw blinds or drapes to block the sunlight  
during the hottest part of the day.  
25. Locate water heaters as close to the points  
of hot water as possible. (The longer the  
supply pipe, the more heat lost.)  
13. People generate heat. So lower the  
thermostat a degree or two when expecting a  
large group of guests. Otherwise your home  
may be wastefully overheated.  
20. Install awnings over windows exposed to  
direct sunlight.  
26. Repair leaky faucets promptly. A steady drip  
of water can waste many gallons per month  
and the energy used to heat it.  
21. In the cooling season, don’t run kitchen and  
bath exhaust fans longer than necessary.

27. Running water is wasted water. When you  
shave, use a sink stopper. When you  
handwash dishes, use a dishpan.  
22. Don’t place lamps, TV sets or other heat-  
producing devices beneath a wall-mounted  
thermostat. Rising heat from the equipment  
may cause the air conditioner system to  
overcool your house.  
14. When possible, locate any window air  
conditioning units on the north or shady side  
of the house.  
Clean and check  
15. Set the thermostat as high as comfort will
