Knowledgeable and Most Importantly Skilled

I was throughly impressed with the level of service and professionalism I received from TE Certified Electrical, Plumbing company. More significantly from the plumbing service employees Josh R. and Jerry. They demonstrated knowledge of their trade. Unlike other plumbing services quick to right a quote without a thorough assessment. They rerouted my main waterline without devastating my lawn and the installation was seamless and professional. The staffing customer service was also professional at all times. Very pleased.

Upon arrival tenant. She stated upstairs air conditioner is not cooling. Tenant walked me around and showed me the furnaces, thermostats and condenser units. Upon visual inspection of condenser units could hear compressor running and upstairs system, but there was no heat being pulled. Upon a visual inspection of the furnaces could not hear refrigerant flowing. With tenant approval did a thorough inspection on both systems. The main level system is not flowing refrigerant. Replaced capacitor and this did not change anything. Standing pressure in system is 238 on both sides. Even installed a hard start kit with no change. Did a mega home test and compressor shows bad. Will quote a compressor replacement. This system has a very dirty almost completely impacted condenser coil. A basic lack of maintenance has ruined the outdoor equipment. Upon inspection of furnaces, these are 2004 Bryant furnaces. Both have very bad failed heat exchangers. Both are no longer a suitable source for heating

Today we came out for ac not keeping up client had his thermostat set on 70 and it went up as high as 77 in the peak of the day. Inspected full hvac system 2015 Goodman 2.5 ton ac with 60k 2020 furnace. On ac side found completely impacted condenser coil causing extreme strain on compressor, contactor is pitted from wear and tear and condenser fan motor is pulling 1.3 amps max on data plate is 1.1 amps. Checked refrigerant pressures found very high suction pressure indicating damage to valves. On return side of duct system vents in floor are very small and restricting air flow. On the kitchen den side of the house there is a return that is panned off in the floor that is not hooked up anymore. The return and supply plenum are not sealed properly and pulling foreign air from crawlspace which is not healthy to breathe . There is no emergency drain pan or any flood safeties and pump is not level. Scheduled install supervisor to give options on updating ac and coil with a duct modification

We performed a 200 amp service upgrade. We installed a new 200 amp meter/main disconnect on the outside of the home. We installed an overhead service on the outside of the home. We also installed a new 200 amp main panel inside the home. We installed gfci protection for all required circuits. We also installed a new grounding system with two ground rods. The main water coming into the home is plastic. We also installed a whole home surge protector. We install smoke detectors in all of the bedrooms and one in the main hallway. We mentioned to the homeowner about having romex in outdoor conduit along with non weather rated outlets. We also discussed fixing junction boxes in the attic with no cover along with installing a box and cover for an open splice. Everything is working upon departure.
