Based on our findings today, it might be time to think about getting a brand new system. Performed 1 system , diagnostic found evap coil compacted, rusted coil, as well. Unit is 33 years old. Unit is also low on R22 tested charge and found pressures at 98 psi but no liquid refrigerant while hooking up the line and unhooking the line. No data plate found for outdoor unit. Due to age of unit, and condition of system customer requested estimate for system replacement.

Quoted price to repair the toilet flange only. Remove the toilet and noticed that the flange was not attached to the toilet riser. The toilet flange is an inside 3 inch toilet flange not an inside 3 inch PVC elbow. This particular flange created a larger gap between each fitting. price to repair the toilet flange only. Remove the toilet and noticed that the flange was not attached to the toilet riser. This particular flange created a half inch gap in between the actual elbow that is turned up, vertical off the drain line and the flange itself. Removed the flange and the elbow. Replaced the elbow with a street elbow and a new 4 x 3 toilet flange. Ran anchors in through the floor to secure the flange to the floor. Installed new wax seal and supply line. Tested with no leaks. Documented all work with pictures. sealed around the base of the toilet.

Client explained he had water showing up in the ceiling directly below the boys bathroom top floor, which is center of kitchen. Tested the system. Found the top floor drain line back up water after few minutes of running the bathtub. Also noticed the toilet flange is not connected to the Drain elbow which is allowing water to escape when the drain line fills. Cut drywall not responsible for drywall repair. Contacted dispatcher to schedule drains for the drain line clearing and flange repair. Documented all work with pictures.

What price to install new client provide a kitchen faucet, waterpressure regulator, and disposal. Client water pressure was 90 psi at left side of building. Client explained when she runs the shower in the master bathroom. She cannot turn on any other fixtures without starving the system. Tested and found when you run multiple fixtures the water virtually disappears. Client has a major volume issue as the water comes into the building. With the excessive pressure I recommend client change the water pressure regulator, which I believe may be causing the volume restriction. Installed new water pressure regulator and tested with no further issues. Installed new disposal and kitchen faucet tested with no issues. Documented all work with pictures. Client provided only the kitchen faucet.

Luis was very knowledgeable and explained everything carefully so that I could understand. He also went above and beyond to make sure my electrical panel was up to date and provided suggestions for some items that may need some further upgrades. His work was clean and fast and my charger looks amazing and works! He's also very friendly and humble, and TE Certified is lucky to have someone with his acumen and personality on their team.
