Q: What rebates or financing options are available for new HVAC systems?

We offer financing through Service Finance , with several plan options and online approval. Service Finance sets the rates and terms. For rebates, what you can claim depends on who supplies your electricity, not on your city. Most Mill Valley homes are on MCE, which offers heat pump rebates for single family homes the owner has lived in for at least 12 months. Watch MCE's timing rule: solar, battery storage or EV charging can't be added for 12 months after the heat pump goes in. MCE pays its rebate through contractors on its participating list. The federal heat pump tax credit (25C) ended for systems installed after December 31, 2025, and TECH Clean California is no longer taking new single family reservations, so we don't count on either. Our California heat pump rebate guide covers what is still available, and we'll supply the equipment and permit documentation your application asks for. See all rebates & financing offers >>

Mill Valley HVAC Help You Can Count On Every Time

Our Mill Valley HVAC contractors hear a lot of the same questions from homeowners trying to get the most out of their heating and cooling systems. We’ve gathered those answers here to help you make smart, simple choices for your home.

We offer financing through Service Finance, with several plan options and online approval. Service Finance sets the rates and terms.

For rebates, what you can claim depends on who supplies your electricity, not on your city. Most Mill Valley homes are on MCE, which offers heat pump rebates for single family homes the owner has lived in for at least 12 months.

How much does HVAC repair cost in Mill Valley, CA?

We don’t quote a repair price before we’ve seen the system, because the same symptom can come from a small part or a major component. Pricing for Mill Valley homes works like this:

The diagnostic visit is $189, and we waive it if you go ahead with the repair.
No hourly billing. After diagnosing the problem in person, we give you a written price before any work starts.
Home Protection Plan members pay nothing for the diagnostic.
Evenings and weekends cost more than a weekday visit, and we tell you the after hours rate when you call.

How can I tell if a repair is worth it or if I need a new system?

There’s no single dollar figure that settles it. A common rule of thumb is to consider replacement when a repair would cost more than half the price of a new system, especially on equipment more than 10 to 15 years old that keeps needing work. Energy bills that rise without any change in how you use the system are another sign.

After we diagnose the problem you get a written price for the repair, and if replacement is worth a look, we’ll put both options side by side so you can decide.
