Heating & Cooling Calculators

Calculate HVAC project costs, equipment operating energy, conductive home heat loss and repair-versus-replace scenarios.

Available heating & cooling calculators

8 calculators for this project type.

Heating & CoolingAir Conditioner Cost CalculatorSeparate equipment, installation and line-set costs, then examine a cooling energy scenario with your chosen efficiency and operating hours.

Heating & CoolingFurnace Cost CalculatorCompare rated furnace fuel use with your quoted equipment, venting, removal and installation costs.

Heating & CoolingHeat Pump Cost CalculatorEstimate rated heating electricity and itemize a heat pump installation budget without assuming local market prices.

Heating & CoolingMini Split Installation Cost CalculatorPlan mini-split indoor zones, complete line-set lengths and separate equipment and contractor cost components.

Heating & CoolingDuctwork Cost CalculatorCalculate main and branch duct stock separately before adding fitting, insulation and installation quotes.

Heating & CoolingHVAC Repair vs Replace CalculatorCompare lifetime-of-decision costs for repairing an existing system versus installing a quoted replacement.

Heating & CoolingAir Conditioner Electricity Cost CalculatorConvert a seasonal delivered cooling scenario into modeled AC-only kilowatt-hours and energy charges.

Heating & CoolingHome Heat Loss CalculatorCompare envelope heat transmission and an optional sensible infiltration scenario at a specified temperature difference.

Planning heating & cooling projects

Furnace and heat-pump tools use different fuel and efficiency measures; mini-split budgets account for the number of indoor zones. Ductwork needs measured branch and trunk runs. AC Electricity and Heating vs Cooling estimate operating energy, whereas Repair vs Replace compares stated future cost assumptions.
