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

Once you’re looking at a $2,500 repair bill, replacement starts making a lot more sense. If your system is already 16 years old and breaking down, how long before the next big problem hits? We get calls all the time from people whose electric bills doubled over two years because their system is dying slowly. A new system ends the repair headaches and cuts those monthly bills in half.
