D&H services all types of air conditioning units in the Westway Homesites neighborhood.

Every day our HVAC technicians come back to our service centers with many stories related to air conditioning repair services. We decided to share some.

Today on the south-west side of Tucson, around Three Points on AZ-86. It’s always a pleasure to drive out of town to service our clients’ A/C units. D&H Air Conditioning serves many clients in Sahuarita, Green Valley et other small communities along I-19. Here, our client is under a Guardian Planned Maintenance Agreement, and this is a report on this maintenance call. The A/C unit we are servicing works day and night, 24/7. We started by clearing out the condensation drain. Then, checked and tightened all electrical connections and the blower housing. We checked amp draws on the blower motor as well as the current controller under load. It gave us a 40 reading, within factory specs. We checked the supply and return air temperature supply: the return air temperature was within 17° to 24° split. We checked all pressures and drawers, the current controller for condenser amp draw. Worked OK. The current controllers were OK too. We did clean up the wiring and replaced a 7.5. The current controller is under warranty. We also remounted the current controller, and cleaned the condenser coil. At this time, all is operating at normal levels. We recommended a compressor saver, a coil guard, a unit surge protector, and a Pristine air cleaner. The A/C technicians at D&H Air Conditioning pride themselves in doing a thorough job: we know our job is important to our clients’ health and well-being.
