HVAC Calculators

Heat pumps, mini splits, boilers, duct work, refrigerant, service agreements — every calculator an HVAC technician needs to quote complete systems and close jobs at the right margin.

HVAC Pricing That Accounts for What the Job Actually Costs

HVAC pricing requires equipment sizing, labor estimation, refrigerant management, and service agreement pricing — each with enough variables to make flat-rate quoting difficult without good tools. The calculators on this page cover the full range: right-sizing equipment for the load, pricing installations, maintenance agreements, and the service call rate that covers your overhead.

Oversizing is the most common HVAC mistake — and a callback waiting to happen. Start every replacement quote with the BTU Sizing Calculator to confirm the load before you spec equipment.

Service agreements are where HVAC businesses build recurring revenue. The Maintenance Agreement Pricing Calculator helps you price plans that build margin — not just give away tune-ups at cost.
