Customer had two drain slow draining bath tubs and shower , we ended up snaking both drains . The master shower had a lot of lime scaling so I chipped away at the lime scaling as much as possible after testing the drain is flowing normally , I’ll let the customer know that I recommended treating the line to help either way at the lime scaling. Customer said she will buy a treatment from Home Depot., I also snake the upstairs bathroom her son’s bathroom and removed a lot of hair and after removing the hair, the drain is working perfectly

Troubleshot loss of power to newly installed disposal. Every time the disposal would be turned on it would immediately trip the breaker. Disposal was disconnected and would still trip as soon as the switch turned on. The wire running from the wall to the disposal was damaged and causing the breaker to trip when a load is put on. Damaged wire was removed, 1900 box and outlet were installed below the sink and a new cord was installed and the disposal was rewired. Disposal was tested and works perfectly fine now.

Replace a garbage disposal in the kitchen sink Customer called us out for a garbage disposal that was failing. Upon arrival customer stated that the disposal kept on tripping the breaker the last couple of weeks and that they noticed a leak coming under the sink. Upon arrival I checked for power and we didn’t have any, the breaker had tripped. I ran water on both sides of the sink to ensure we had proper flow in the drain. I ran water on the disposal side and noticed a leak coming from the bottom of the disposal. The customer decided to proceed with a replacement, I removed the old disposal and removed any water. We installed the new garbage disposal and did a test to ensure we had power, and we were good. I went to test it again and the breaker tripped. We have an electrician coming out today to further investigate. We tested for any leaks around our work and there was no signs of a leak.

Poured 1 gallon of water down drain. Customer confirmed downstairs that water was draining and took video on her phone. Water flow is good with no issues. The wall that had mold in the bedroom was open so I was able to check the drain going down the wall and it was perfectly dry with no issues found.

Performed 1 system cooling diagnostics on a 2012 R22 Goodman system. I found that the system had a failed capacitor for the AC condenser. The system was also low on r22 refrigerant and short on return air. The system also needs updated flood protection. The homeowner has me replace the failed capacitor and setup a time with an install supervisor. Customer was advised that Incant repair the refrigerant leak due to the r22 system being obsolete. Will roll the costs of the capacitor towards the costs of the system replacement of the purchase the AC system from us in the next 30 days. The system (heat a cooling) was temporarily running when I left. I flushed the drain line with water enzymes and added clean out tablets.

Performed 1 system cooling diagnostics on a 5 year old Lennox system that cools the mainfloor. The outdoor unit was only receiving 55 volts due to an electrical issue. The unit randomly then starting receiving 220 volts as needed to run. *** The breakers in the main electrical panel appear to be original to the home and are faded and not labeled. The breaker for the mainfloor condenser (outdoor) unit is more than likely starting to fail. The breaker should be replaced with a new 20 or 25 amp breaker. A licensed electrician needs to replace that breaker, label it and do an inspection on that circuit to make sure that there are no more issues; so the outdoor unit can safety get 220 volts continuously (outdoor disconnect may also need to be replaced). *** The unit was also short on refrigerant and duct work. The homeowner approved to have me add the missing refrigerant. The system may have a refrigerant leak; a l ram maybe needed in the future. I emailed an estimate to perform a leak

Everyone I interacted with at TE was professional, customer-oriented, and honest. Mauricio and Chris—the two electricians who helped rewire my kitchen—did a phenomenal job. They walked me through the entire process, consulted with me on key decisions, and were genuinely great to work with. Mauricio is the kind of guy you could sit down and have a beer with. Together, he and Chris are true professionals who make TE look great and serve as fantastic ambassadors for the company. I was very impressed
