Estimate the installed cost of a ductless mini split system based on number of indoor zones, system capacity, efficiency rating, installation complexity, and regional labor pricing.

Estimate the electricity cost to run a mini split air conditioner or heat pump based on system wattage, daily runtime, local electricity rate, operating days, and efficiency mode.

Estimate the operating cost of a mini split system based on cooling capacity, efficiency, daily runtime, electricity rate, and seasonal usage.

Estimate the electricity use and operating cost of a mini split system based on cooling capacity, efficiency, daily runtime, local electricity rate, and operating days per month.

Estimate the recommended mini split size and installed cost range for a garage based on square footage, insulation, climate, ceiling height, and whether the garage is attached or detached.

Compare estimated annual heating cost savings when switching from an oil furnace to a heat pump based on annual heating demand, oil price, electricity price, furnace efficiency, and heat pump efficiency.

Compare estimated annual heating costs for a heat pump versus a gas furnace based on home heating demand, local electricity and natural gas prices, heat pump efficiency, and furnace AFUE. The result shows the annual cost difference, where a positive value means the heat pump costs more to run and a negative value means the heat pump costs less.

Estimate the total installed cost to replace a heat pump based on system size, equipment efficiency, installation complexity, ductwork modifications, and regional labor pricing.

Estimate annual savings from switching to a heat pump based on current annual heating costs, expected heat pump efficiency, electricity price, climate, and available incentives.
