it is important to have the proper balance between the air being supplied to each room
and the air returning to the cooling and heating equipment.
Proper balance and sealing of the duct system improves the efciency of the heating
and air conditioning system and improves the indoor air quality of the home by reducing
the amount of airborne pollutants that enter homes from spaces where the ductwork
and/or equipment is located. The manufacturer and the U.S. Environmental Protection
Agency’s Energy Star Program recommend that central duct systems be checked by a
qualied contractor for proper balance and sealing.
2.2 CHECKING PRODUCT RECEIVED

age. Units with damaged cartons should be opened immediately. If damage is found, it

not to damage the unit. Check the unit rating plate for unit model number, unit size, coil
model, voltage, phase, etc. to assure the unit matches the job specications.
