Our client reached out to us to have a couple of stop valves replaced underneath the bathroom vanity sink that was recently installed by the client. Water was shut up to home and work began. Work is complete and test for leaks and no leaks were found. Several estimates have been left and will be emailed along with this invoice. They recommend the current water heater on the property to be replaced.

Performed HomeCare maintenance on two systems. Upstairs system has a condensate drain that doesn’t have enough pitch, insulation is poor, and low on refrigerant. Repaired condensate drain to help drain better and not to back up, added new insulation to copper, and added 410a to system. Main floor has a faulty condensate pump that wouldn’t shut off. Replaced pump under warranty. Restored flame sensors. Cleared pressure switch tubings. Blower motors are pulling correct amps. Blower wheels are clean. Wet switch and ss1 are working properly. Flue pipes, gas sediment traps, and gas lines are up to code. cleared condensate drains. Replaced 413 filters. Condenser coils are clean. Capacitors and contactors are in manufacture specs. Pressures are good. Disconnects are working properly. Recommend adding a APCO X to each system to help improve indoor air quality and to help keep systems clean.

Performed 2 system diagnostic for main and upstairs unit. Upstairs: found failed compressor, dirty blower wheel, blower motor drawing higher amps,pitted contactor and no flood protection . Furnace 23 years old and coil/condenser is 14 years Main:found failed compressor, dirty blower wheel, failed blower motor drawing extremely high amps Recommendations, pitted contactor , no water safeties, no drain pan. Due to age of units and cost of repairs. Would recommend replacement of both units. Cause of failure is power surge that grounded compressor. With new install would recommend adding surge protectors to protect the units. Based on our findings today, it might be time to think about getting a brand new system.

Alex misdiagnosed our issue and encouraged us to buy a $10k digital panel. The issue persisted, a different TE technician came out, and diagnosed a different issue. Glad we did not purchase the $10k panel.
