A commercial customer in La Habra CA reported that their office air conditioner was not working. EMS showed the unit had multiple faults. Upon arrival, our technician troubleshooted the #5 Lennox unit and found it off on high head pressure with a loose connection on the condenser fan motor relay. Repaired, reset and ran unit. No more issues to report, confirmed site is back to normal with EMS.

Commercial A/C tech was dispatched for approved quoted repairs at a check cashing place in La Habra, California. Tech replaced an old, faulty t-stat with a new Honeywell thermostat. Stat was programmed to the store's preferences, site cool and working well.

Performed preventative maintenance on 5 Lennox units. Changed filters, checked amperage, and tested safeties. Measured refrigerant levels and cleaned out blower housing. Belt tension and condition is fine.
