Home Energy Cost Calculator:

The peak Heating & Cooling loads will be fairly close to the size of your heating system. Your mechanical subcontractor will size it more accurately before procuring it but this will be a fairly accurate number to use for estimating costs.

Note: This calculator is designed to be used for comparing different insulation and HVAC combinations for the purpose of selection and budgeting during pre-construction. For simplicity, it has limitations and should not be used as a substitute for a Manual J or Manual S calculation. It is not a guarantee of your heating and cooling costs since this calculation does not account for some site specific factors such as shading, solar gain, or ducts placed outside of the building envelope.Note that energy prices fluctuate significantly over time. It's important to consider energy price volatility as a factor in your decision of which HVAC systems to install.
