Central Air Conditioner Services
Whole-home cooling systems using ductwork distribution.
Central air conditioning systems cool your entire home through a network of ducts. An outdoor condenser unit removes heat while an indoor evaporator coil absorbs heat from circulated air. This mature technology provides effective whole-home cooling when properly sized and maintained. Central AC pairs with your furnace or air handler, sharing the ductwork and blower system.
How Central Air Conditioners Work
The outdoor condenser compresses refrigerant and releases heat outside. Cooled refrigerant flows to the indoor evaporator coil. The blower circulates indoor air over the cold coil, removing heat and humidity. Cooled air distributes through ductwork to every room. The cycle repeats until your thermostat setpoint is reached.

Central Air Conditioner Maintenance Tips
Efficiency Information
Central AC efficiency is measured in SEER (Seasonal Energy Efficiency Ratio). Current minimum standards require SEER 14-15 depending on region. High-efficiency units reach SEER 20+. Upgrading from an older SEER 10 unit to SEER 16 can reduce cooling costs by 40%. Bay Area mild summers mean AC runs fewer hours than hot climates, but efficiency still impacts costs.
Expected Lifespan
Well-maintained central AC systems typically last 15-20 years. Coastal areas with salt air may see shorter lifespans. After 10 years, repair costs should be weighed against replacement value. Newer systems offer significantly better efficiency, potentially justifying earlier replacement.
Bay Area Considerations
Many Bay Area homes, especially in the fog belt, use AC infrequently. Systems may sit idle for months, making pre-season maintenance valuable. Inland areas like the Tri-Valley need robust AC for heat waves. Coastal humidity can affect coil conditions. Victorian homes often lack ductwork for central AC, making ductless systems more practical.
Central Air Conditioner FAQ
How often should my central air conditioner be serviced?
Annual maintenance is recommended, typically before the primary use season. Cooling equipment in spring, heating equipment in fall.
What is the typical lifespan of a central air conditioner?
Well-maintained central AC systems typically last 15-20 years. Coastal areas with salt air may see shorter lifespans. After 10 years, repair costs should be weighed against replacement value. Newer systems offer significantly better efficiency, potentially justifying earlier replacement.
How do I know if my central air conditioner needs repair?
Your central AC needs attention when you notice these warning signs: Warm air from vents despite system running. Weak airflow compared to normal. Unusual cycling on and off frequently.
