Sooooooo Good!!!!

Blake has been so very helpful getting me through my ordeals with a leaky water main line. In finishing up he went above and beyond and found another issue which I need to take care of. He is meticulous and very easy to talk to about the issues

The best service!

Received the best service today with an annual AC/Heater unit inspection. Caleb was great and thorough. I would highly recommend TE Certified and especially Caleb for any AC/Heater needs (as well as plumbing and electric).

Excellent service, but prices are high

Ricky Newsome the plumbing technician was very professional and pleasant to work with. He did his work very cleanly, answered my questions patiently. He gave me the impression and confidence that TE Certified is a good company. Their prices are quite high (30-40% more) compared to competitors though. I hope they can reduce their prices. Otherwise I would highly recommend this company as a repeat customer.

For this job, we replaced 3 bathroom faucets in the home. One wide spread faucet in the guest bathroom off of the kitchen. The other two in the master bathroom. We also as a courtesy fixed one handle on the Roman tub valve in the master bathroom, and fixed one pop up assembly in the upstairs guest bathroom. Once complete we cleaned up, and tested our work. Thank you for choosing TE Certified.

Signed the customer up for a 3 system Homecare plan. Performed a Homecare maintenance inspection on all 3 HVAC systems in the home (upstairs, main floor and basement). Tested heating, cooling and auxillary heating from the thermostats. Measured the refrigerant pressures and electrical component readings. Inspected the safety and cleanliness of the systems. Checked and replaced the 1” air filters. Reported findings to the customer.

Perform heat exchanger replacement on the upstairs system, tested operations with gas heat adjusted gas pressures to manufacturer specifications also ran a carbon monoxide test to ensure that there is no carbon monoxide present in the home. At this time, the system is operating properly.

Customer called us out for a back up in the master bathroom. On arrival I tested the shower and sinks. The sinks started to gurgle but not the toilet. I recommended running a tub gun through the shower drain to clear the blockage. Customer agreed. I ran the tub gun through the shower and successfully cleared the blockage. I tested the drain by running the shower and sinks. I then cleaned the shower. Customer did have cast-iron outside but wanted to call us out on a later date.

Connect mainline that was put in from a different company outside by tying in the waterlines at the meter and drilling through a new penetration point into the garage where the mainline is located will be located in the garage next to the water heater and running behind the water heater which I will have to temporarily remove for access, connecting back to the plumbing system.

2 System Inspection Cycled each system through heat and cool from the thermostat. Changed both 1 inch filters, flushed drain lines with 2 gallons of hot water, took temperature readings at indoor equipment, inspected heat exchangers, blower motors, and coils. Checked and tightened all electrical connections, used multimeter to check all motors, power enhancers, and high wear components. The main level system is right at 15 years old and has some major concerns regarding the Gas Furnace. There are multiple cracks and small rust holes In the Heat Exchanger. The blower wheel is dirty/impacted with debris, which is reducing air flow across the heat exchanger and coil. The inducer motor is over amping, the hot surface igniter is weak and failing, the flame rectifier is also weak and reading below manufacture parameters, and the condensation pump ran for over 15 minutes trying to pump out water. The impeller is dirty and damaged. Due to the age, condition, multiple parts outdated, and th
