Upon arrival client stated the UL system leaked out of the system onto the ceiling below in the master bedroom. There was not any extensive damage to the ceiling that is observable at this time. Water has been drying for a few days. UL drain line is clogged and pumped the drain out, flushed 2 gallons of water with enzymes and drain is currently clear. 16x25x4 filter is clean and upon cycling system on in cooling mode, all operating parameters are within range at this time. These systems are 12 years old and reaching their life expectancy. I recommend our annual preventative homecare maintenance plan to ensure your systems are operating to the best of their abilities.

Thermostat lost power due to a clogged drain line. I was able to clear the drain line (mighty pump, vinegar , nitrogen) and it’s clear now. If it happen again, next option would be to install a condensate pump to the system. System is working properly at this visit with no other issue.

Technician installed the client-supplied kitchen faucet and verified proper operation. The dishwasher supply line was replaced, and a hammer arrestor was installed to help reduce water hammer and protect the plumbing system. Under the kitchen sink, the PVC drain piping was rerouted to provide proper drainage, and a new garbage disposal was installed. The basket strainer was replaced as a courtesy, along with the Studor vent (air admittance valve), to ensure the drain system vents properly. At the water heater, the existing thermal expansion tank was replaced, pressurized to 70 PSI and securely mounted to the wall for added support. Once all work was completed, the plumbing system was filled, air was purged from the lines. At the time of completion, everything was operating properly with no leaks observed.

On today’s visit I met with the homeowner. The homeowner expressed an issue with a garbage disposal they wanted removed. I wrote up some estimates to perform work and received approval. I removed the existing garbage disposal and put in new basket strainer and tubular as well. I put wire nuts on the wiring and cut off the breaker at the panel. I leak tested to confirm everything was draining with no leaks. I set a lead for an electrician to come out 8/3/26 to properly terminate the garbage disposal. I also have a lead set for service to come out for a PRV estimate. The customer is now happy and satisfied with the work that was performed. Remove basket strainer and collar, includes replacement of: strainer, collar, tail piece extension, trap, and p-trap for one compartment sink, test and clean up work area.

No cool upstairs. Upon arrival found 2019 Lennox 1.5 ton heat pump system was off and it was 81 degrees upstairs. Turned system on to find indoor fan would run but outdoor unit would not kick on. Upon inspection found the dual capacitor had failed, contactor was pitting, condenser was dirty, blower was dirty, drain line had a cracked fitting and system lacked TE standard flood protection. Gave options to customer in regards to repairs. Customer wished to proceed with all necessary repairs and sign up for Homecare plan. Cleaned condenser and blower, fixed drain line, added wet switch and inline drain switch. Replaced contactor and dual capacitor. Tested system after repairs made and flushed 2 gallons of water and coil cleaner down drain to clean and verify no leaks. System is operating at the time of departure. Did notify customer it will take an hour to an hour and a half per degree for system to catch up to set point of 70 on thermostat.

For this job the customer stated the washer machine would cut off due to no water being detected especially when the shower was ran at the same time. Checking the pressure to the home showed 65 psi, however, when I began running the shower I noticed a significant pressure drop to 40 psi. I explained to the customer they had a pressure issue due to a bad pressure regulator. I also noticed the expansion tank not strapped and brought that to the customers attention as well. The customer agreed to replace both. Water was shut off to the home and a new pressure regulator and expansion tank was put in. I then set the pressure to 65 psi and started a load of laundry while running the shower. The washer finished its cycle with no error codes.

Arrived on site for a no cool. Thermostat was blank and they had no cooling. After getting some history on the system and its performance they also shared with me how poorly it’s been keeping the space all summer. They said on hot days it won’t even get down to 80 degrees and they can seldom get below 75 degrees in the lobby. We began by locating the wet switch that tripped due to a drip from the supply plenum sweating. We also flushed and cleared the drain, ensuring it is functional, which it was. The system only has 1 return and it’s partially blocked from a wall they had put up. They also haven’t changed the filter is an extremely long time which affects system performance. The ultimate smoking gun was the fresh air intake that was ducted to the return plenum pulling in outside air into the air stream. The the space was 77 degrees but the temperature at my filter was 88 degrees. Also there was no filter door so attic air was being pulled in as well. All duct work is original and wou

Upon arrival spoke to customer about a leak above the water heater on a polybutylene tee. Water heater is 9 years old and needs to be replaced due to being very out of code. No thermal expansion protection is on the system and water heater will have to be repiped and brought up to code to add expansion tank. Removed section of polybutylene and rebuilt section in pex. Made two connections to polybutylene with poly to pex adapters. Te certified takes no responsibility for any connections made to polybutylene or any polybutylene in the home as polybutylene is a condemned piping system. Almost all of the home has been repiped with pex but according to the customer a few small sections remain in the home. Restored water to the home and no leaks were present.

TE was quick with getting me on the schedule next day, my technician was great, personable and knowledgeable. After a full workup of the system he was able to determine the issue and fix it. They gave me a few options on other things I could do and while I declined those for now I liked the option to have a sort of "yearly maintenance plan" with them. 5\5 would recommend.
