HVAC Consulting & Design

Thanks for printing!  Don't forget to come back to PV Heating & Air for fresh articles!

There’s no charge for these valuable custom services when you buy your system from PV.

Heating and air design and consulting is a frequently overlooked practice for Atlanta HVAC contractors, but not for PV. We think it’s one of the most important aspects of system selection, and we specialize in two different HVAC designs:

Manual J Load Calculation

The Manual J Load calculation determines the best size or "tonnage" for your heating and cooling system.

Just as a tailor takes measurements for a custom suit, we measure your home's square footage, windows, building material, insulation values, sun orientation, building leakage, duct leakage, and other elements. This helps build a "tailor fit,” fully optimized comfort system for your home

Remember: Bigger isn't always better when it comes to HVAC systems. Oversized systems lead to high humidity levels, expensive utility bills, and an uncomfortable home environment.

Manual D Duct Design

Think of your ductwork like your body’s respiratory system. You’ve got to match the return, or “breathing in,” duct and the supply, or “breathing out,” duct to optimize your system’s efficiency and lifespan.

That’s where Manual D duct design comes in. We always follow best practices for ductwork customization to ensure that your ducts and your heating and air system “match.”


HVAC zoning offers optimal comfort and energy savings by dividing your home into areas, or “zones,” with similar heating and cooling needs. You can heat and cool these areas independently, exercising more control over temperatures in different parts of your home.

With a zoned system, you can change the temperature settings in one part of your house the same way you control the lighting in different rooms. Let PV help you zone your traditional split system or install separate indoor fan coils and multiple indoor units onto a single outdoor system.
