Room
air conditioners and dehumidifiers: How
to use them properly and efficiently
Room Air
Conditioners
Room air
conditioners can be a very efficient way
to cool one room or a small area of your
home. It's important to follow these guidelines
to be sure the unit runs properly:
-
Don't run your room air conditioner when
the temperature inside or outside is too
low (below 60 degrees). Since air conditioners
cool air by as much as 30 degrees, the unit's
evaporator coils might freeze up if it's
cooling air to temperatures below freezing.
- Be sure the evaporator coil on
the room air conditioner is clean. This
will ensure proper air flow and prevent
it from freezing up.
- Check the fan motor. A slow fan
motor causes poor air flow over the evaporator
coils, which may then freeze up.
- Check the air filter, and replace it if
necessary. A dirty air filter will also
cause poor air flow over the evaporator
coils. We offer a universal, cut-to-fit
filter that works for all standard room
air conditioner models.
- A low Freon charge may also cause
evaporator coils to freeze up. If you suspect
this problem, we recommend you have a lisenced
appliance repair technician check the Freon
in your unit.
- Be sure your room air conditioner
is tilted slightly backward to allow
water to flow to the back of the unit. From
there, the water will evaporate outside
the house.
Dehumidifiers
- Raise your dehumidifier up several
feet by placing it on a sturdy table. This
will help keep the coils on the back from
freezing up as the room air is warmer nearer
the ceiling.
-
Use a garden hose to drain your unit. Many
dehumidifier drain buckets have a fitting
on them where you can attach a garden hose.
This is helpful as it enables you to drain
the unit to a floor drain instead of manually
draining it when the bucket fills.
NOTE: You may have to knock or cut out a
plug on the fitting first. Buy a garden
hose plug for the fitting if you don't plan
to keep the hose connected to the dehumidifier.

Appliance
fun fact
Air conditioning was not invented for comfort.
In 1902, Willis Haviland Carrier, a recent
engineering graduate of Cornell University,
was hired by the Buffalo Forge Printing Company.
Fluctuations in heat and humidity in the printing
plant were causing the paper to change dimensions,
which led to misalignment of the colored inks.
Carrier created an air conditioning machine
to add moisture to the air in order to create
stable temperature and humidity levels in
the plant. His success at Buffalo Forge made
aligned four-color printing possible.
Carrier
came up with the concept of air conditioning
while waiting for a train. It was a foggy
night and he was going over in his mind the
problem of temperature and humidity control.
By the time the train arrived, Carrier had
an understanding of the relationship between
temperature, humidity and dew point. In 1928,
Carrier developed an air conditioner designed
for human comfort and private home use called
the Weathermaker. |
