Make the quotes comparable
A low number often means something is left out. Before you compare prices, compare scope. Every quote should cover the same work and the same equipment, or you aren't comparing like with like.
What a good quote includes
- The contractor's name, address, phone and California license number.
- Exact equipment: brand, model numbers and capacity, not just a brand name.
- What is being done to the ducts, vent, gas line or electrical, in writing.
- Whether the permit and inspection are included, and who pulls them.
- Duct testing, if the job needs it. California requires independent testing on most HVAC replacements.
- Warranty terms for parts and for labor, and how long each lasts.
- A payment schedule tied to progress, and a start and finish estimate.
- What is not included, such as drywall, paint, or electrical panel upgrades.
Red flags
- No license number, or a number that doesn't check out.
- A price quoted over the phone with no look at the house.
- A sizing recommendation based only on the size of your old unit, with no load calculation.
- Pressure to sign today, or a discount that expires tonight.
- A large deposit up front. California limits home improvement down payments; the Contractors State License Board explains the current rules.
- No mention of permits. Unpermitted work can cause trouble when you sell.
Verify the license
Anyone can look up a California contractor's license on the Contractors State License Board website: status, classifications, bond and workers' compensation. Ours is #1086420, and you are welcome to check it.
