Does a HVAC technician need a license in California?
Any job worth $1,000 or more in labor and materials must be done by a CSLB-licensed contractor. For hvac work that means a C-20 Warm-Air Heating, Ventilating and Air-Conditioning license from the Contractors State License Board (CSLB). You can check any license number on the board's website before you hire.
How do I choose the right HVAC technician in Walnut?
Compare at least three pros. Check that their license is active with your state licensing board, ask for proof of insurance, read recent reviews, and get the scope, price and timeline in writing before work starts. Avoid paying the full amount up front.
Is it free to get quotes from HVAC technicians on Contractors2Hire?
Yes. Sending a request and comparing quotes is free, with no obligation to hire. You pay the pro you choose directly for the work.
How often should I service my HVAC system?
Once a year for each system — the AC in spring and the furnace in autumn. A tune-up catches small problems early and keeps the warranty valid on many units.
When should I replace instead of repair?
If the system is over 12–15 years old, uses R-22 refrigerant, or the repair is more than about a third of the cost of a new unit, replacement usually pays off in lower energy bills.
