HVAC contracts with the equipment, the permit and the HERS test spelled out
From a change-out to a full system, describe the equipment and the homeowner gets a contract with model numbers, duct work, Title 24 items and payments tied to startup.
License class: C-20 Warm-Air Heating, Ventilating and Air-Conditioning
Your first 3 contracts are free. No credit card.
What an HVAC scope has to say
- Equipment by manufacturer, model and capacity (tons / BTU / SEER2), and what is being removed.
- Ductwork: replaced, sealed or reused, and duct leakage testing if required.
- Electrical, gas line, condensate, pad and disconnect work included.
- Permit, Title 24 compliance forms and HERS verification, and who pays for them.
- Thermostat, startup, commissioning and the manufacturer warranty registration.
§7159 points that catch HVAC contractors
- Equipment deposits are still down payments: $1,000 or 10%, whichever is less, until the equipment is delivered to the site.
- A payment on delivery of equipment is allowed only if the contract says the payment is for materials delivered.
- The contract must say whether you carry workers' compensation; CSLB cross-checks it against your license.
- Title 24 and HERS costs belong in the price or in a clear allowance, not as a surprise invoice.
