Free Estimates on New Systems
Operation Air Inc. will provide you with a free upfront estimate to replace your
HVAC system or to replace your duct system. Our technicians will evaluate the
cooling and heating needs of your home or office to help determine the right
system or duct design that is suitable.
Proper System Sizing
Manual J Heat Load
Operation Air Inc. utilizes the Manual J Heat Loss/Gain Load Calculation
program to accurately determine the proper system size and the design of the duct
work. A number of factors are taken into account, such as the overall size of the
home, orientation, individual room sizes, type and number of windows, and
insulation values.
Far too many companies rely on the "rule of thumb" method to size equipment
by basing the system tonnage on the number of square footage of the home. This
often leads to an improperly sized system because it fails to take into account the
previously mentioned factors. The most accurate way to determine the correct
system tonnage is calculated by the Manual J Heat/Loss Gain method.
Oversized
An oversized system will cause the system to "short cycle" by frequently
cycling on and off. This will not only decrease it's efficiency but it does not allow
the system adequate time to remove the latent heat (humidity) in the air.
Oversized systems generally have a shortened life expectancy due to the wear and
tear on the components.
Undersized
An undersized system will require the system to work harder and run longer to
remove the sensible heat from the home or office in order to reach the desired
temperature during the hottest days. For these reasons, new equipment should
always be sized by a licensed professional according to Manual J heat load
calculations.
Warranty
Operation Air Inc. offers extended warranties on new installations. A standard
warranty may include a 10 Year warranty on parts and compressor, in addition to
a 1 year labor warranty.

The ACCA (Air Conditioning Contractors of America) states, "Make sure that your contractor
uses the Manual J® residential load calculation procedure. Insist on it! Manual J is the official
standard for residential load calculation and is required by many building codes around the
country."
