Real emergency service

DiBiase actually has on call technicians! 24/7! Chris worked in the dark and serviced the AC on the spot, preventing serious trouble we didn’t know was lurking. All this from a call because the thermostat wasn’t working (battery contacts needed cleaning. Who knew?). Incredibly prompt and professional and a really nice guy as well. They’ve got our business for sure!

Found water inside auxiliary pan, customer stated system has It’s been shutting off on wet switchAnd can hear water dripping from the back of the air handler, inspect drain, draining ok, inspect coil pan, noticed 3/4 drain is connected to secondary auxiliary port, added 1 gallon of water into pan and noticed starting to drip behind air handler and back of coil. Removed 3/4 plug from primary drain and found clogged port, water is backing into pan, and dripping behind unit, connected drain line to primary port and plugged secondary port, flushed drain with 2 gallons of water did not see any dripping behind unit, told customer to keep an eye on unit it problem continues to happen, we need to pull out coil to inspect pan for cracks, we might have enough slack on line set we will try disconnect coil without cutting line set, two men will be needed.

Chiller outlet pipes are condensing/sweating esp at chiller pump and parts of piping that are not insulated. Condensate is piped to mechanical room with only an inch of 1 1/2” PVC protruding from wall. Wall fan/coil unit not draining, pan switch open. Replaced 16x25x2 filters with 16x25x1 filters. Air Temp splits measured @ air handler k. 57% RH @ return in basement. Penny approved estimate to pipe 1 1/2” PVC condensate to floor drain in mechanical room. Office to contact Belen Martinez-Gomez to schedule date/time to pipe condensate.
