Common Questions
How do I estimate HVAC costs?+
Start with a load calculation to determine the right equipment size. Price the equipment (AC, furnace, or heat pump), add ductwork materials and labor, include the thermostat and accessories, and factor in permits and start-up. A full residential HVAC replacement typically costs $5,000-$15,000+ depending on system type and home size.
What markup should I charge for HVAC work?+
HVAC contractors typically mark up 35-55% on labor and 20-30% on equipment. Equipment margins are lower due to the high base cost. Your total project margin should target 30-40% gross profit to cover overhead, warranty service, and business expenses.
What should an HVAC estimate include?+
Include equipment specifications (brand, model, tonnage, SEER/AFUE ratings), ductwork scope, thermostat, permits, load calculation reference, labor breakdown, manufacturer and workmanship warranty terms, start-up/commissioning, and any electrical work required for the installation.
Should I include a load calculation in my HVAC estimate?+
Yes. A Manual J load calculation determines the correct equipment size and demonstrates professionalism. It protects you from liability if a customer complains about comfort or efficiency. Many jurisdictions require it for permit approval.
