Apollo Heating and Air Conditioning: Best HVAC Repair Serving South San Francisco, CA 94080

In our coastal climate, a common culprit is a refrigerant leak, which reduces cooling efficiency and forces the system to work harder. Improper system sizing from a previous installation can also cause this, as an oversized unit short-cycles and an undersized one never reaches the set temperature. Our technicians perform a thorough diagnostic check, including a leak test and system performance analysis, to pinpoint the exact cause and recommend the most effective repair or adjustment for your home.

It depends on the age, condition, and efficiency of your current system. We recommend repair for newer systems or minor issues. If your furnace or AC is over 15 years old, requires frequent and costly repairs, or leads to unexpectedly high energy bills, a replacement with a properly sized, modern unit is often a more cost-effective long-term solution. Our experts provide a clear, honest assessment, explaining the pros and cons of repair versus replacement so you can make an informed decision for your home and budget.

Our maintenance service is designed to keep your system running reliably and efficiently. We perform a comprehensive check that includes cleaning coils, checking refrigerant levels, inspecting electrical connections, lubricating moving parts, testing system controls, and checking for any signs of wear. This proactive care helps prevent unexpected breakdowns, maintains your manufacturer's warranty, and can improve your system's energy efficiency, which is especially valuable for managing home comfort in South San Francisco's varied weather.
