Air Conditioning Services

Discover Our Wide Range of Air Conditioning Services

Most Marin County homeowners accept that summer means choosing between sky-high energy bills or sweltering in rooms that never cool down properly, but we challenge you to demand better from your air conditioning system. The real tension lies between settling for mediocre cooling and getting the central AC repairs, ductless mini-split installations, seasonal tune-ups, coil cleaning, drain line maintenance, and refrigerant recharging that actually make every room in your home comfortable.

Central Air Conditioning

Installation | Replacement | Repair

Want consistent cooling throughout your home? Central air conditioning delivers even temperatures in every room while keeping energy costs reasonable.

Ductless mini-split installation

Zoned cooling without ductwork.

Mini-splits cool exactly the rooms you want without tearing up walls for ductwork, and they’ll cut your cooling bills in half.

Seasonal Air Conditioning Tune-ups

Routine inspections to maintain peak efficiency and extend system life.

Regular seasonal tune-ups keep your air conditioning running smoothly when you need it most, preventing costly breakdowns and keeping your family comfortable all summer long.

Coil Cleaning

Improve energy efficiency and lower energy bills.

Coil cleaning prevents the expensive breakdowns that happen when dirt buildup blocks airflow and forces your system to overheat, keeping your home comfortable and your repair costs low.

AC Drain line cleaning

Prevent water damage and improve indoor air quality.

Your AC produces condensation that needs to drain properly, and our cleaning service removes the buildup that causes backups and protects your home from water damage.

Refrigerant Recharging

Effectively cool your home & protect your system.

Refrigerant recharging fixes weak cooling and stops your AC from running all day, which immediately reduces your electric bill and restores comfort.

How much does HVAC repair cost in Marin County, CA?
HVAC repairs in Marin County typically cost between $325 and $1,650, with your final price determined by the specific component that needs attention and the complexity of the fix. Basic repairs like capacitor or contactor replacements stay around $350-550, while major issues like compressor failures or heat exchanger problems reach the higher end. We protect your wallet by providing fixed-price bids after proper diagnosis instead of hourly billing that leaves you vulnerable to open-ended costs and paying for inefficient work. You’ll know your exact investment before we touch your system, guaranteeing no budget surprises or hidden fees.
How can I tell if a repair is worth it or if I need a new system?
If your repair costs more than half what a new system would cost, or your system is over 15 years old, replacement makes more financial sense. The technical reality is that systems older than 12 years use outdated refrigerants and components that become increasingly expensive to source and repair. Your energy efficiency drops dramatically after the 15-year mark, with older units consuming 40-60% more electricity than current models to achieve the same cooling or heating output. When major components like compressors or heat exchangers fail, you’re looking at repair bills between $2,000-4,000 that rarely extend the system’s life beyond another 2-3 years.
