Five vetted Morgan Hill HVAC contractors. Real phone numbers, real addresses, recent reviews, and what each one does best. From the South Valley Spotlight team.
Most South Valley HVAC failures happen on the first 100 degree day in June or the first 30 degree morning in December. The list below is the crews we would actually hand a neighbor who calls in a panic. We focused on local crews that pull permits, hold an active C20 license, and have at least 25 reviews so the rating is real.
Every business below is operating right now, has a working phone, and a license you can verify at cslb.ca.gov. Phone and website got a working-link check before we published.

What to watch for in South Valley
CSLB C20 license is mandatory
Anyone changing out a furnace or AC condenser in California needs a C20 (Warm-Air Heating, Ventilating and Air-Conditioning) license. Ask for the number, then verify at cslb.ca.gov before any work starts.
Permits are required for change-outs
Morgan Hill requires a mechanical permit for any AC or furnace replacement, including like-for-like swaps. A crew that says you do not need a permit is a crew you do not want.
R-454B refrigerant changes the math in 2026
EPA rules forced manufacturers off R-410A as of January 2025. Equipment using R-454B costs 5 to 12 percent more, and not every installer is trained to handle it safely. Ask whether the crew is EPA Section 608 certified for the new refrigerant.

FAQ
How much does it cost to replace an HVAC system in Morgan Hill?
For a typical 2,000 to 2,500 sqft Morgan Hill home, expect $11,500 to $16,500 for a full furnace plus AC change-out installed. Heat pump conversions run higher at $14,000 to $19,500 before rebates. The R-454B refrigerant transition has pushed pricing 5 to 12 percent higher in 2026.
Do I need a permit to replace my AC or furnace in Morgan Hill?
Yes. The City of Morgan Hill requires a mechanical permit for any HVAC equipment change-out, including like-for-like replacements. Permit fees run $200 to $400. A licensed C20 contractor pulls this for you.
Are heat pump rebates still available in Morgan Hill?
Yes. The federal Inflation Reduction Act offers up to $2,000 in tax credits for qualifying heat pumps. Silicon Valley Clean Energy (SVCE) layers a $1,000 to $1,500 rebate on top. Combined incentives can drop a $14,000 heat pump install to a net $10,500.
How long does a new HVAC system last in the Bay Area?
Properly maintained, expect 12 to 18 years for a furnace and 10 to 15 years for an AC condenser. Heavy use during 90 degree summers shortens AC life on the upper end. Annual tune-ups extend the curve.
