We prioritize energy efficiency and long-term performance, ensuring your system is ready for any unexpected heatwave that rolls through San Francisco.
Climate Considerations
San Francisco’s mixed, variable climate presents unique challenges for HVAC systems. While our average summer temperatures hover around 80°F, heat spikes can put significant strain on cooling equipment that sits idle for much of the year. Properly maintaining your system is essential to ensure it performs when you need it most, rather than failing during a rare but intense warm spell.
AC Services Tips
Schedule an annual AC tune-up before the summer season to catch refrigerant leaks or electrical issues early.
Change your air filters every 1 to 3 months to improve airflow and indoor air quality.
Keep the area around your outdoor condenser unit clear of debris, plants, and foliage to ensure proper heat exchange.
Consider upgrading to a smart thermostat to better manage cooling cycles and optimize energy efficiency.
If your AC is blowing warm air, check your thermostat settings and breaker box before calling for professional diagnostics.
Frequently Asked Questions
How much does AC repair typically cost?
Costs vary based on the nature of the issue, such as whether it involves a simple capacitor replacement, a frozen AC coil, or a refrigerant leak. A licensed technician will diagnose the specific component failure and provide upfront pricing before beginning work.
Why is my AC running but blowing warm air?
This is often caused by a dirty air filter, restricted airflow, low refrigerant levels, or a malfunctioning compressor. It is best to have a certified professional inspect the system to identify the root cause.
Is it better to repair or replace an old AC unit?
If your AC repair cost is high relative to the age and efficiency of the unit, replacement is often more cost-effective. We generally recommend replacement for systems over 12-15 years old that require frequent, expensive repairs.
How long does a central AC system typically last?
Most well-maintained central air conditioning systems last between 15 and 20 years. Signs of failure include frequent breakdowns, rising energy bills, and difficulty maintaining a consistent temperature.
What SEER rating should I choose for the San Francisco climate?
In our mild climate, a mid-range SEER2 rating usually provides the best balance between upfront equipment costs and long-term energy savings. A professional can help calculate the most efficient option for your specific home size.
How often should I get my AC serviced?
We recommend an annual AC tune-up, ideally in the spring. A professional tune-up includes cleaning coils, checking refrigerant levels, inspecting electrical connections, and verifying system performance.
How do I know what size AC unit my home needs?
Proper sizing is determined by a professional load calculation that considers your home's square footage, insulation, and window orientation. Oversizing an unit can lead to poor humidity control and frequent cycling.
How can I lower my cooling bills and improve efficiency?
Improving home insulation, using window coverings during peak sun hours, and ensuring your HVAC system is clean and properly charged with refrigerant are the most effective ways to lower cooling costs.
Should I choose central AC, a ductless mini-split, or a heat pump?
Central AC is ideal for homes with existing ductwork. Ductless mini-splits are excellent for homes without ducts or for zoning specific rooms, while heat pumps offer efficient heating and cooling in one system.
What should I expect during a professional AC installation?
A professional installation includes removing the old unit, sizing the new equipment, ensuring proper refrigerant charge, and testing for electrical safety. Depending on the scope, the process may require local permits and a final inspection to ensure code compliance.
