Perform one system diagnostic or main level unit. Found indoor unit operational and pushing air. However, air was not cold. Upon inspection of the outdoor unit found compressor not operating. Well attaching hoses found no refrigerant coming out of the lines. While checking the compressor found the compressor was in internal lockout and overheated. The temperature for the compressor at the time of lockout was 134° and climbing. Once I cool down the compressor to below 75° and powered the system compressor was operational for a total of three minutes before the compressor went out again on internal lockout. Due to the age of the system type a failure would recommend replacing the system however we are able to repair the system as well. The blower wheel and the condenser coil is also dirty. The bare minimum would be to replace the compressor and refrigerant however without the proper cleanings there would be more issues in the future. Based on our findings today, it might be time to think

Tenant called in for service. We visually inspected the system with the tenant and found an extremely dirty filter for upstairs unit which could have caused freezing. Informed him they should be changing filters every three months. Also showed him where the other filters are for the main and basement systems. Customer approved diagnostic and we completely checked indoor and outdoor. Found many issues with airflow that include lack of return and supply ductwork. The drain line has no slope and should be reran with the correct pitch. Contactor is pitted, lack of flood protections installed, and tons of buildup of dust/dirt in returns.

Customer stated that the first floor bathroom sink supply lines had been leaking recently, so she shut the valves off to prevent further leaking. During today’s inspection, the home water pressure was tested and measured at 65 psi, which is within the normal operating range. The home also has a 32 year-old water eater that is still functioning at this time, however, due to his age, its remaining lifespan is unknown. The customer is not interested in replacing the unit at this time Per the customers request, we replaced the supply lines only. After installation, the system was turned back on and tested for leaks, and everything is working properly at this time.

Clear blockage Customer was experiencing a blockage in the tub on the 2nd floor. Upon arrival I tested for a mainline issue and after running water in the other fixtures only the tub was being affected. I tested the rest of the bathroom groups to ensure we have proper flow. I ran cable machine to attempt to clear blockage and we were successful. I tested the tub for backups and we restored proper flow. We are leaving estimates to replace three toilets.

For this job, we worked on providing and installing three dedicated 20 amp 120 V circuits. The first circuit was installed in the electrical panel room right under panel for the security system. before the security system was plugged into another outlet in the room that was also connected to a few other outlets in the break room, which kept tripping from overloading. that way security system can be on its own, and not ever shut off if anything else was to ever trip again. The other two circuits were installed in the break room for future use of space heaters. Last time we came out, they were connecting multiple space heaters on one circuit in the break room so as I explained to the staff, now they have two dedicated circuits where they can run a space heater on each, without having to overload the existing circuit, which is there for extra use.

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

We have used TE services for electric issues few times. They are usually prompt to respond and we had same day service which was good. But Their charges when the work is complete always SO MUCH HIGHER than estimated! I called for outdoor lighting not turning on as usual, so I called them and service estimates was $800. When the work was completed, he said that it is $998! Last month, I called them for fire detector making noise, They end up whole house smoke detectors electrically connected costing $3800! I might have to search for more reliable electricians when it comes for final charges.
