Questions and Answers

What should I do if my heat pump isn't heating or cooling efficiently?

A common issue for San Leandro homes is a gradual loss in heat pump efficiency, often due to refrigerant leaks, dirty coils, or component wear. As a family business with three generations of HVAC experience, we recommend a professional diagnostic check. We'll inspect your system, clean critical components, check refrigerant levels, and ensure it's operating at peak performance to keep your energy bills in check.

How often should I schedule HVAC maintenance?

For reliable performance, we advise San Leandro homeowners to schedule professional HVAC maintenance at least once a year—ideally before the peak heating or cooling season. Our maintenance service includes cleaning components like your air filter, checking system pressures, and ensuring all parts are functioning correctly. This proactive care helps prevent unexpected breakdowns and extends the life of your system.

What's involved in a full HVAC system replacement?

A full system replacement, or 'cut-in,' involves removing your old heating and cooling equipment and installing a new, properly sized system, including updating ductwork and thermostats if needed. As a licensed and insured local contractor, we handle the entire process—from the initial load calculation to ensure efficiency to the final testing—providing clear communication and quality workmanship throughout.
