A new heating or cooling system is a big purchase, and the installation matters as much as the equipment. Here's what to check before you hire anyone, us included.
Check the license
In California, heating and air work totaling $1,000 or more (labor and materials together) needs a contractor licensed by the Contractors State License Board. HVAC contractors usually hold a C-20 license. Look the license number up on the CSLB website: it shows whether the license is active, the classifications, the bond, workers' compensation coverage and any complaints. Our license number, 399854, is at the top of every page of this site.
Ask about permits
Replacing a furnace, air conditioner or heat pump almost always needs a permit, and many jobs need a third-party energy test as well. A contractor who suggests skipping the permit is asking you to take the risk. See does new HVAC need a permit.
Expect them to look before they quote
A good quote for a new system comes after someone has looked at the house: the size of the rooms, insulation, windows, the ductwork and how the current system performs. A quote given over the phone, or simply matching the size of the old unit, can miss problems the old system had. See what size system you need.
Get it in writing
A written estimate should name the equipment by brand and model, say what's included (removal of the old system, permits, testing, any ductwork, electrical or thermostat work), and spell out warranties on parts and labor. In California, a home improvement contract over $500 has to be in writing and gives you a right to cancel, usually within three business days, and longer for some homeowners.
Questions worth asking
- Are the technicians your own employees, or subcontractors?
- Are your technicians certified? (NATE certification is a good sign.)
- Who registers the equipment warranty? See your warranty.
- What happens if something goes wrong after installation?
- Do you service what you install?
Red flags
- No license number, or one that doesn't match the name on the truck
- Pressure to sign today, or a price that's only good right now
- A large deposit up front: in California, a home improvement down payment can't be more than $1,000 or 10% of the price, whichever is less
- "We don't need a permit for this"
- A price far below everyone else's, without an explanation of what's left out
