Professional Certified Manual J Calculation You Can Rely On

At Manual J Express, we provide accurate and fast certified Manual J calculation reports for homeowners, contractors, and HVAC professionals. Our reports ensure your systems meet code requirements and your permits are approved without delay.

Why Certified Manual J Calculation Is Essential for HVAC Permits

Most homeowners and contractors want the same thing: a system that runs well and a permit that gets approved without back-and-forth. A manual J calculation does that. It proves the heating and cooling system is the right size for the house.

Without it, you’re guessing, and inspectors don’t like guesses. A proper heat load calculation for permit checks insulation, windows, and climate data. It’s the piece of paper that turns a stack of forms into an approval stamp.

HVAC Heat Load Calculation Services We Provide

Every house is different, and so are the reports it needs. That’s why we don’t stop at one service; we cover all the key types of HVAC heat load calculation services.

Residential Heat Load Calculation

A residential heat load calculation is the backbone of any HVAC project. We measure the living space, insulation, doors, and even how the sun hits the walls. From there, we give you numbers that keep the home comfortable. Not too hot in summer, not freezing in January.

Heat Pump Manual J Calculation

Heat pumps are tricky, size them wrong and you’ll be stuck with long winters of cold air blowing through the vents. Our heat pump manual J calculation makes sure you choose equipment that matches your space. The reports take into account the dual heating and cooling load, so one setting doesn’t overrun the other.

HVAC Permit Calculation Service

Permits are where projects often hit a wall. Our HVAC permit calculation service keeps the process moving. We don’t just send out half-done spreadsheets. We prepare clear reports with Manual J load calculation, equipment data, and duct sizing if needed. Everything is tied up, so the inspector has no reason to push it back.

How Our Manual J Load Calculation Process Works

We’ve built a process that saves time and avoids mistakes. Think of it as a checklist we never skip.

First, we gather home details, square footage, insulation type, window sizes, and the climate zone.
Then we run a certified HVAC heat load calculation service using ACCA-approved software.
Finally, we deliver stamped reports ready to hand to the building department.

It’s straightforward, but it works. Every time.

We allow unlimited revisions without extra fees. And we do it all at a fair rate, so you don’t have to stretch your budget.
