HVAC Companies Serving Modesto, CA

Modesto HVAC Pros is an independent referral service. We connect you with independent, third-party HVAC contractors in the Modesto area — we don't perform HVAC installation or repair work ourselves. The companies below are listed for informational purposes based on public business listings and search results — we haven't independently audited their licensing, insurance, or work quality, and inclusion here isn't an endorsement. Always verify a contractor's license status yourself at the CSLB license lookup (cslb.ca.gov) before hiring.

How to choose an HVAC company in Modesto

• Verify their CSLB C-20 license status directly at cslb.ca.gov — don't rely on a website badge or claim alone. Here is how to read the record, field by field.
• Get at least two quotes for anything beyond a minor repair, especially for a full system replacement (our heat pump or central air comparison helps frame those quotes).
• Ask directly about permit handling for installation jobs — see our permit requirements guide.
• For AC emergencies, ask about current same-day availability and any after-hours fee before committing.
