How to choose an HVAC contractor in Poway

1. Look up the license

Heating and air conditioning work in California calls for a C-20 license from the Contractors State License Board. Ask for the license number and look it up on the CSLB website. The record shows whether the license is active, the business name it belongs to, its bond and workers’ compensation status, and any disciplinary actions.

2. Ask about insurance

A contractor working in your home should carry general liability insurance, and workers’ compensation if they have employees. Ask for proof.

3. Expect a diagnosis before the work

For a repair, a good technician tells you what they found, what needs to be done and what it will cost before they start. You should be able to say no at that point.

4. Ask about permits for replacements

Replacing an air conditioner or furnace in California generally requires a permit, and Title 24 can add duct testing. In Poway the permit goes through the city; in Rancho Bernardo and other San Diego neighborhoods, through the City of San Diego. A contractor who skips permits leaves you without an inspection and can cause trouble when you sell.

5. Get the scope in writing

For an installation, the written contract should list the equipment model numbers, what is included (such as a new coil, line set or thermostat), the permit, warranty terms and the payment schedule. California law limits the down payment on most home improvement contracts and gives you a right to cancel within a set number of days, so ask about both.

Questions worth asking

• What is your C-20 license number?
• Will you run a load calculation before recommending a size?
• Is the permit included?
• What warranty comes with the parts and with your labor?
• Who do I call if something goes wrong after the install?

Red flags

• No license number, or one that doesn’t match the business name
• Pressure to decide on the spot
• A replacement quote with no visit to the house
• “We don’t need a permit for this”
• A large cash payment up front
