Manual J Load Calc
We measure each room, count windows, and note ceiling height. The result is a precise BTU target per zone. You get a system sized for your home, not a guess.
New Construction HVAC — El Dorado Hills, CA
El Dorado Hills homes sit on sloped lots with high ceilings and large windows. That floor plan needs precise duct design from day one.

Custom and semi-custom homes in El Dorado Hills often have split levels and open great rooms. Those features push heat and cold into odd pockets. Fresh Air runs a full Manual J load calc and Manual D duct design on every new build. We spec the right ton count and lay out ducts that reach every room. That work prevents hot spots and high bills before the walls close.

El Dorado Hills split-levels need duct runs that go around beams and floor changes. We design the path before framing is done so runs stay short and static pressure stays low.
California Title 24 sets minimum duct sealing and system efficiency rules for new builds. We meet those rules on every job and provide the test report for your permit file.
El Dorado Hills sits at roughly 500 to 800 feet in the Sierra Nevada foothills. Summer highs push past 100 degrees. Winter nights drop into the 30s. A system sized for a flat valley home will short-cycle or underperform here. We use local climate data when we run your load calc.
