AC Systems We Service in San Francisco
Our technicians are trained and certified to repair a wide range of residential air conditioning systems throughout. These include:
We service traditional split systems with indoor air handlers and outdoor condensers, San Francisco's most common cooling setup. Our AC unit repair work covers compressor replacements, refrigerant leak detection and recharge, evaporator coil cleaning, blower motor repairs, and capacitor replacements.
Increasingly popular for room additions, older homes without ductwork, and energy-efficient cooling zones. Our air conditioner repair services handle refrigerant line repairs, indoor unit drain clogs, outdoor compressor issues, and remote control or circuit board failures.
We repair reversing valve issues, defrost cycle problems, auxiliary heat malfunctions, and seasonal performance decline. Heat pumps work harder in extreme temperatures, so prompt air conditioner repair prevents costly breakdowns.
For homes that rely on a dual-fuel setup, addressing year-round heating and cooling needs with professional furnace repair ensures seamless climate control when seasonal temperatures drop.
No matter what system you have, we stock parts for common repairs and can typically source specialized components quickly when needed.

Most Common Air Conditioning Repairs We Perform in San Francisco
Our air conditioning repairs in San Fransico, CA, address the most common issues that cause cooling failures and inefficiency. Here’s what we fix:
Faulty Circuit Boards
Circuit boards control compressor timing and fan speeds. Power surges or moisture cause failures that prevent startup, create erratic cycling, or trigger error codes.
We diagnose with voltage tests and install OEM replacements.
Thermostat Problems
Faulty thermostats create temperature swings, constant cycling, or complete unresponsiveness. We verify wiring connections, recalibrate sensors, and confirm system compatibility. Outdated models get upgraded to programmable or smart versions for improved efficiency.
Capacitor Failures
Capacitors deliver the electrical jolt needed to start compressors and fans. Failed capacitors produce humming sounds without startup or cause random shutdowns. We carry common sizes for fast replacements.
Worn-Out Contactors
Contactors manage electrical flow to compressors and motors. Burned contact points produce clicking noises and prevent reliable starts. We measure voltage levels and swap out degraded units.
Dirty or Damaged Condenser Coils
Blocked coils trap heat instead of releasing it, forcing longer run times with reduced cooling output. We apply low-pressure cleaning and assess structural integrity. Bent fins or refrigerant leaks require repair or coil replacement.
Clogged Air Filters and Evaporator Coils
Blocked filters choke airflow and ice up evaporator coils. Every air conditioner repair visit includes filter inspection. Ice buildup gets safely removed before we correct the underlying airflow problem.
Refrigerant Leaks
Insufficient refrigerant reduces cooling power and threatens compressor longevity. Electronic detectors and UV dye pinpoint leak locations. We seal breaches, evacuate moisture, and restore proper refrigerant levels.
Blower Motor and Fan Issues
Deteriorating bearings, overheating motors, and broken blades compromise air circulation. We measure electrical draw and airflow performance. Burned-out motors get replaced with durable, quiet-running alternatives.
Every air conditioner repair service we perform in San Francisco includes a full system check to catch secondary issues before they become expensive problems.
