How to Use This Template
- 1
Start with a cover page that lists your HVAC contractor license, EPA 608 certification, and manufacturer dealer certifications (Carrier, Trane, Lennox, etc.). HVAC installations are the most expensive mechanical system in a home — clients are spending \$8,000–\$25,000 and they need confidence in your credentials.
- 2
Your executive summary should recommend a specific system and explain why it is the right fit. For example: "Based on our Manual J load calculation (36,000 BTU cooling, 45,000 BTU heating), we recommend a Carrier Infinity 24VNA0 variable-speed heat pump with a SEER2 rating of 24, paired with a matching air handler and smart thermostat." Lead with the outcome: comfort, efficiency, and reliability.
- 3
Include a Manual J load calculation summary that shows the home’s heating and cooling loads. This is what separates a professional HVAC proposal from a guess. Detail the equipment specifications, duct modifications (new runs, sealing, insulation), refrigerant line sets, electrical requirements (disconnect, whip, breaker), condensate drain, thermostat, and any zoning controls.
- 4
Map your timeline to permit and inspection milestones: permit application, equipment delivery, installation days, refrigerant charge and startup, inspection, and client walkthrough. Tie payment milestones to these stages: deposit at contract signing, progress payment at equipment set, balance at successful startup and inspection. Include both manufacturer warranty registration and your workmanship warranty.
Frequently Asked Questions
Why should I include Manual J calculations in my HVAC proposal?
A Manual J load calculation sizes the equipment to the home, not the other way around. Including it shows the client that your recommendation is engineered, prevents oversizing (which causes short cycling and humidity problems), and differentiates you from competitors who guess. Many jurisdictions now require it for permits.
How should I present SEER ratings in my proposal?
List the SEER2 (or SEER) rating for cooling and HSPF2 for heating. Show the estimated annual energy cost savings compared to the existing system if possible. Clients understand that higher ratings mean lower bills, but they need you to quantify the benefit to justify the higher equipment cost.
Should I include duct work in my HVAC proposal?
Always assess and address the duct system. State whether existing ducts are adequate, need sealing, need insulation, or need new runs. A new high-efficiency unit connected to leaky ducts wastes 20–30% of its capacity. Documenting duct scope protects you from comfort complaints after installation.
What warranties should an HVAC proposal include?
Include the manufacturer’s equipment warranty (typically 10 years on compressor, 5 years on parts with registration), your workmanship warranty (1–2 years covering installation), and note that you will register the equipment with the manufacturer on the client’s behalf. State what is excluded: filters, maintenance, damage from power surges or improper use.
