Building estimate for solar system for client, with rooftop installation on cottage
Performed tune up on air conditioner, cleaned filter and outdoor unit. Checked capacitor, contactor, electrical connections, refrigerant levels and amperage draw on compressor, condenser fan motor and blower. Found system not designed properly, 3 ton upflow furnace in garage with 3 ton evaporator coil and 3.5 ton condenser outside. Refrigerant level is fine but not working correctly indoor unit is flooding with refrigerant and outdoor unit is starving of refrigerant due to lack of airflow from undersized furnace and coil. Compressor is using a large amount of energy due to system not designed properly. System cools but not the way it should or how it will with a new properly designed system for the home.
Performing AC maintenance on 2 systems, both 1998 Bryant condensers, for one of our certified members in Los Altos Hills. Cleaned up and tested refrigerant levels, inspected and tested safety and electrical components and made recommendations as needed. One system is struggling at this time, compressor motor is making a loud noise and pressures are fluctuating indicating that there may be noncondensibles in the refrigerant lines - no filter line drier in place.
