What is a Manual J? 

For a long time now, the way professionals calculate the size of equipment needed is by tons per sq. ft. or BTU per sq. ft.   

A Manual J is the exercise of calculating the size of the heating and cooling equipment in more details then just sq. ft.  It takes into account how tight a home is, insulation levels, windows, sun light and much more. 

Today's advanced sophisticated software can accurately size the heating and cooling systems so that they are right-sized for a home.  A right-sized heating and cooling will mean years of comfort, lower utility bills and even lower repair bills. But all of that can only happen if the equipment is sized correctly.  

We serve contractors, builders, architects, engineers and homeowners and we can have your manual J done in as little as one day.
