1. Check for a Valid California HVAC License

Always confirm your contractor has a valid C-20 HVAC license issued by the California Contractors State License Board (CSLB). Search your contractor’s license here. This ensures they meet state standards for safety, technical knowledge, and legal responsibility.

Tip: A licensed contractor should also carry general liability insurance and workers’ comp.

2. Look for Local San Jose Experience

The best HVAC contractors understand the Bay Area’s climate patterns, local permitting processes, and common HVAC setups in San Jose homes from Eichler-style houses to newer builds with tight insulation.

Ask:

  • How many projects have you completed in San Jose?
  • Are you familiar with local rebate programs (like BayREN or PG&E incentives)?

3. Read Verified Google & Yelp Reviews

Reputation matters. Look at:

  • Star rating (aim for 4.5+)
  • Recency of reviews
  • Mentions of professionalism, response time, and post-install support

Top-tier HVAC contractors like us work with trusted brands like Mitsubishi , GREE , Bryant, or Cooper & Hunter, Daikin. Make sure:

  • The brand offers a good manufacturer’s warranty
  • The contractor offers their own labor warranty (1 year minimum is standard)

This shows they stand behind their workmanship.

A clear estimate should include:

  • Equipment cost
  • Labor charges
  • Permit fees
  • Rebates or discounts

Avoid contractors who give vague or verbal-only quotes. Transparency is key.
