How to Use This Template

  1. 1

    Fill in your company’s legal name, HVAC contractor license number, EPA Section 608 certification, insurance details, and the client’s full name and property address. HVAC work requires specific certifications for refrigerant handling, and listing these credentials in the contract demonstrates compliance and professionalism.

  2. 2

    Specify every piece of equipment by manufacturer, model number, SEER/SEER2 rating, tonnage or BTU capacity, and whether it includes a smart thermostat or air quality components. Instead of "install new AC system," write "Install Carrier Infinity 24VNA0 variable-speed air conditioner, 3-ton, 24 SEER2, with Carrier Infinity Touch thermostat and matching Carrier FE4ANF003 evaporator coil." Reference the Manual J load calculation that supports the equipment sizing.

  3. 3

    Include separate warranty sections for equipment and workmanship. Most major HVAC manufacturers offer 5–10 year compressor warranties and 5-year parts warranties, but only if the equipment is registered within 60–90 days of installation and installed by a certified dealer. Your workmanship warranty should cover installation defects, refrigerant leaks from connections, and ductwork for one to five years.

  4. 4

    Add a maintenance agreement clause for ongoing service. Many HVAC contractors offer annual or semi-annual maintenance plans that keep the equipment warranty valid. Specify what each maintenance visit includes (filter replacement, coil cleaning, refrigerant check, electrical testing) and the cost for the first year. This creates recurring revenue and strengthens client relationships.

Frequently Asked Questions

What equipment warranty terms should an HVAC contract include?

Your contract should list both the manufacturer’s warranty (typically 5–10 years on compressor, 5 years on parts) and your workmanship warranty (1–5 years on installation). Specify that the manufacturer’s warranty requires professional registration within 60–90 days, annual maintenance by a licensed technician, and that you will handle the registration. State what voids each warranty, including DIY repairs and failure to change filters.

Why should an HVAC contract reference a Manual J load calculation?

A Manual J calculation determines the correct equipment size for the home. Oversized equipment short-cycles, wastes energy, and fails prematurely. Undersized equipment runs constantly and never reaches comfort levels. Referencing the calculation in your contract proves the equipment was properly sized and protects you from complaints about performance or high energy bills.

How should an HVAC contract handle refrigerant?

Your contract should state that all refrigerant handling complies with EPA Section 608 regulations. Specify the refrigerant type (R-410A, R-32, or R-454B), the initial charge amount, and that recovery of existing refrigerant from old equipment follows EPA guidelines. If the system uses a newer low-GWP refrigerant, note any special handling requirements.

Is this HVAC contract template legally binding?

This template provides a professional starting point for HVAC service agreements. However, HVAC licensing requirements, EPA regulations, and contract laws vary by state. We recommend having a licensed attorney in your state review and customize the template for your business. This template does not constitute legal advice.
