Fast, Licensed, Manual J Calculations
Get your Permit & Avoid Expensive Energy Bills…

Let’s face it, You’re probably here because you’ve been asked for a Manual J Load Calculation either by your builder or your city building department.

And there’s a number of good reasons for it…

Thousands of Americans live in homes with old, inefficient HVAC systems. Even a 10-year-old home can have a heating and cooling system that was NOT sized correctly.  An improperly sized HVAC system could mean you’re throwing away money on your energy bill and/or creating unhealthy indoor air quality conditions (mold and bacteria).

That’s where a  Manual J calculation comes in.

Investing in a professional Manual J: AC load calculation can save you thousands on your energy bill. Not to mention, an accurately sized HVAC unit will provide the comfort and long life you expect from a brand new Heating and Cooling system for years. 

Manual J is the ACCA approved method
of calculating room-by-room and whole house cooling loads.

Air conditioning & heating systems consume vast amounts of a home’s total energy budget, and of course, they impact your comfort levels more than any other system in a house. Therefore, it’s important your Air Conditioning System receives accurate proper sizing from day one. It will sure haunt you later if it doesn’t.

DO I REALLY NEED A MANUAL J HEAT LOAD CALCULATION FOR MY HOME?

The Answer is Absolutely Yes!
An ACCA Manual J – AC Load Calculation Determines The Amount Of Heat Your Home Loses In Winter & Gains In Summer.

Manual J: A/C Load Calculations can be done room-by-room or for the whole house as a block, allowing you to determine precisely how much conditioned air, in cubic feet per minute CFM each room needs for both heating and cooling.

A Manual J – Heat Load Calculation factors in all the surfaces of the building envelope, with their areas and insulation levels. Each wall is given its proper orientation, as well as the windows and doors attached to them.

Additional important data to include is the location and tightness of the duct system, the infiltration rate of the house, the internal loads (appliances and people), and area where the house is located.

The results specify the BTUH of heat lost by each room in the winter and gained in the summer.

The results specify the BTUH of heat lost by each room in the winter and gained in the summer.

THE HEAT GAIN IS SPLIT INTO TWO PARTS:

  • Sensible (related to temperature)
  • Latent (related to humidity).

AVOID COSTLY OVER-SIZED A/C SYSTEMS!

Get Your Home Air Conditioning Calculation Properly Done, Right From The Start!

ACCA developed its Manual J protocol for heating and cooling load calculations to help HVAC contractors put in correctly sized equipment, but there are a couple of problems:

      • First: most contractors don’t do the load calculations for every new piece of equipment they install. They use rules of thumb instead.
      • Second: when they do the Manual J, they sometimes don’t do them correctly.

We’ve looked over a lot of Manual J reports because the ENERGY STAR homes program actually requires them.

ENERGY STAR doesn’t require a whole lot. Mainly they want to check that the following info is correct:

    • Location
    • Outdoor & Indoor design temperature
    • Orientation
    • Windows
    • Number of People
    • Ducts
