Calculators

Estimate the recommended air conditioner size in BTU/hour based on room area, ceiling height, climate, sun exposure, and occupancy.

Estimate the electricity cost to run an air conditioner based on power draw, daily usage, electricity rate, cooling season length, and AC efficiency type.

Estimate the electricity used and operating cost of an air conditioner based on its cooling capacity, efficiency, daily runtime, local electricity rate, and number of days used.

Estimate the running wattage of an air conditioner based on cooling capacity, efficiency rating, unit type, and operating mode. This calculator helps compare expected power draw for different AC setups.

Estimate the recommended air conditioner capacity in tons based on room size, ceiling height, climate, sun exposure, and occupancy.

Estimate the recommended air conditioner size in BTUs and tons based on room area, ceiling height, sun exposure, insulation quality, and number of occupants.

Estimate the recommended air conditioner size in BTU per hour based on room area, ceiling height, climate, sun exposure, and occupancy.

Estimate the recommended air conditioner tonnage based on room area, ceiling height, climate, sun exposure, and insulation quality. This helps size a residential cooling system for typical home spaces.

Estimate the cooling load for a single room in BTU/hr using room size, ceiling height, insulation quality, sun exposure, and occupants.

Estimate the required HVAC capacity in BTU/hour based on home size, ceiling height, climate, insulation quality, and sun exposure.

Estimate latent heat load from outdoor air infiltration or ventilation using airflow, humidity ratio difference, air density, and moisture latent heat of vaporization.

Estimate sensible heat load using airflow, indoor and supply air temperatures, elevation correction, and system safety factor. The calculation uses the standard HVAC relationship Qs = 1.08 × CFM × ΔT, adjusted for air density at elevation and a design factor.

Estimate the total cooling heat load for a room or small space by combining area-based sensible load, occupancy, equipment, and lighting contributions with insulation quality adjustment.

Estimate the heating load needed for a space using floor area, ceiling height, insulation quality, climate severity, and window area. The result is an approximate BTU/hour requirement for heating system sizing.

Estimate the required cooling capacity for a room or small space in BTU per hour based on floor area, ceiling height, occupancy, sun exposure, and insulation quality.

Estimate the total heating and cooling load for a home using key Manual J factors such as floor area, climate severity, insulation quality, window area, and ceiling height.

Estimate the installed cost range for a commercial HVAC project using building size, cooling load, system type, installation complexity, and regional labor cost factors.

Estimate the installed cost range for a residential HVAC system based on home size, system type, efficiency, ductwork needs, and labor market conditions.
