RESSAC repair tech arrived at an office building in Pasadena, California, to investigate a no-cooling report. Inspected the Amana AC system, discovered fuses blown in the disconnect box. After further discussion with the customer, learned that customer was actually removing the entire thermostat to shut the unit off. Action was causing shorts and excessive unit cycling. Repaired the shorts and wiring issues, instructed customer on normal thermostat operations. Unit working well again, no other issues found.

HVAC technician returned to a mobile provider store in Pasadena, CA, to continue troubleshooting wiring issues on a Lennox split system. Traced the problem to a wiring setup for the electrical heat. Re-wired the AC to run correctly for a heat pump system. Blower motor turned back on and unit started cooling again. No other issues, thermostat programmed for the store, all OK now.

Emergency dispatch to a cell phone store in Pasadena, California, for the AC not working on their sales floor. The technician found the Lennox unit off, evaporator motor shut off and the coil iced over. Defrosted the coil, cleaned up the residual water, turned the motor back on and topped off refrigerant. System will need a full leak search and repair, unit is running temporarily.

RESSAC AC tech arrived at an office building in Pasadena, California, to investigate a noise complaint. After inspecting the HVAC unit over the central skylight area, our technician found the unit producing normal vibrations. However the unit was set on undersized insulation pads that aren't thick enough to this equipment. Will quote new commercial grade spring mounts for customer to reduce vibration noise.

An office building in Pasadena, California, called in to report a water leak. Upon arrival, technician found the site did not have their roof access key, so had to use an extension to reach equipment. Found unit #1 low on refrigerant in the first stage, leak on the bottom of the evap coil. Also found the condensate pan with a broken fitting. Attempted to access and tighten to slow leak, but would not tighten. Will need to quote a new pan, as well as a new evaporator.
