Lafayette Resident - Lafayette, CA
Technician was very thorough. Arrived promptly. Was able to communicate effectively regarding the issues with my furnace and AC.
Ac diagnostic drain line clogged, cleaned and system is up and running.
Providing free second opinion for client that was quoted major repairs on 1998 Bryant condenser and coil, checked system out - tested motor amperages (blower, condenser fan and compressor), tested capacitors and contactor, tested refrigerant levels, inspected evaporator coil. Made minor repair to coil door to prevent air from leaking back into utility closet and gave client full assessment along with estimate for repairs. System functional at this time.
Performed diagnostic on Trane air conditioning system, found high pressure switch and low pressure switch in outdoor unit tripped. Bypassed both to get unit to operate and found refrigerant metering device in the indoor unit is failing which caused both pressure switches to trip as a safety to prevent damage to the compressor. To fix all refrigerant needs to be removed from system, metering device would be replaced as well as a new liquid line filter drier, vacuumed out and then recharged
