Cotati HVAC Company Serving North Bay Homes With Expert Heating and Cooling Solutions

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 Cotati homes are served by Sonoma Clean Power, which offers a heat pump rebate, with a larger one for households enrolled in CARE or FERA. Apply within 90 days of the project being completed, which for most jobs is the date the permit is finaled. 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 >>

HVAC Services from Emergency Repairs to New Systems in Cotati

Bellows handles emergency HVAC repairs, complete system replacements, and annual maintenance throughout Cotati. We fix broken air conditioners, install new furnaces, and service heat pumps so your home stays comfortable.

Air Conditioning Services

Discover Our Wide Range of Air Conditioning Services

Cotati homeowners are upgrading to energy-efficient cooling systems that cut electricity costs while keeping houses comfortable during triple-digit heat waves. We help families replace old air conditioners with central air, add mini-splits to rooms that stay hot, tune up existing systems, and maintain cooling equipment that works reliably all summer.

Central Air Conditioning

Installation | Replacement | Repair

Air conditioning installation costs less than you think and cools your house better than running five window units that jack up your electric bill.

Ductless mini-split installation

Zoned cooling without ductwork.

Ductless systems give you cold air in rooms where you can’t run ducts. Your home office won’t be an oven anymore.

Seasonal Air Conditioning Tune-ups

Routine inspections to maintain peak efficiency and extend system life.

Our tune-ups meet the highest standards and keep your air conditioner working perfectly when summer heat arrives. You get years more life from your system.

Coil Cleaning

Improve energy efficiency and lower energy bills.

Over time, your coils get clogged with dirt. Cleaning them makes your air conditioner cool your house faster while using less electricity.

AC Drain line cleaning

Prevent water damage and improve indoor air quality.

Clean drain lines guarantee your air conditioner removes humidity without backing up water into your home.

Refrigerant Recharging

Effectively cool your home & protect your system.

Refrigerant recharging saves homeowners thousands by making old air conditioners blow ice-cold air again instead of replacing the entire system.

How much does HVAC repair cost in Cotati, 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 Cotati 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.
