HVAC Ton Calculator

Estimate the HVAC cooling capacity needed in tons based on home size, climate, insulation quality, ceiling height, and sun exposure. This calculator uses a BTU-per-square-foot approach with practical adjustment factors, then converts total BTUs to tons.

HVAC Tonnage Calculator

Estimate the recommended HVAC cooling capacity in tons based on home size, ceiling height, climate zone, insulation quality, and sun exposure. This calculator uses a common BTU-per-square-foot approach with practical adjustment factors, then converts BTUs to tons by dividing by 12,000.

HVAC Size Calculator

Estimate the recommended HVAC system size in BTUs and tons based on home square footage, ceiling height, climate zone, insulation quality, and sun exposure.

HVAC Load Calculator

Estimate the required HVAC cooling load in BTU per hour based on floor area, ceiling height, insulation quality, climate zone, window area, and occupancy.

HVAC Payback Period Calculator

Estimate how many years it will take for an HVAC upgrade to pay for itself based on installation cost, rebates, current annual energy costs, expected energy savings, and annual maintenance savings.

HVAC Profit Margin Calculator

Estimate HVAC job profit margin based on total revenue, labor cost, materials cost, overhead allocation, and job complexity. Use this calculator to understand how direct costs and complexity-adjusted overhead affect profit margin percentage on installation or service work.

HVAC Markup Calculator

Estimate the selling price for an HVAC job by applying markup to equipment and materials, adding labor cost, and adjusting for project complexity and overhead.
