Installation Cost Estimating: the tool will estimate total installation price for your new HVAC system, which is based off equipment cost, and national average labor + overhead + profit, that plumbers/HVAC contractors charge for each type of system.

The calculator’s algorithm will select the full size system(s) and the smallest needed system to cover the rest of required BTU load, to give you most cost efficient estimate. ft.), and specifying largest possible BTU lead HVAC system(s) and then the smallest size system for the remainder of the total BTU load.įor example, if your heat load is 150K BTUs, and maximum residential Central AC size is 60K BTUs (5 Ton) then you need two 60K BTU compressors and a 30K (2.5 Ton) system. Multiple heating/cooling systems: Another important new feature is calculating cost of multiple heating / cooling systems being installed in large homes (over 3000 sq.

We also recommend that IF you plan to use the results of this heat load calculation for making your purchasing decisions, you SHOULD verify the results with this long-form Manual J online estimator. Savings in energy cost savings for both cooling & heating can be as high as 15-25%! PRO TIP: Improving home insulation (in walls and attic), and sealing/insulating your air ducts, will have a significant effect on the BTU load of your cooling / heating system. This is where our new algorithm can make an intelligent recommendation, which includes both system capacity (for heating & cooling), appropriate system type, and energy/fuel costs. While BTU heat load calculation was done before this update, many homeowners were unsure which heating and cooling system is best for them.

MASSIVE UPDATE (June 24, 2020): We’ve released an extensive update to the calculator, which took over 150 hours of development time and is now over 900 lines of code! This new release introduces price calculations and HVAC Equipment recommendation algorithm, which provides suggestion based on your climate region, size of your house, presence (or absence) of air ducts and/or baseboard radiators in your home.
