Jonas did a great job troubleshooting and replacing our main meter box. He found several other problems that needed attention and got our home up to code. He arrived in a timely manner, kept me informed of his progress and was a total professional.

Wonderful Experience!

Stephen was wonderful to work with. He was very knowledgeable about the installation process of installing gas and replacing a couple of leaking valves. He was able to do things on the fly adjust accordingly when necessary and had a great attitude and I’m a wonderful personality. Highly recommended. Thank you so much for a wonderful and easy install.

Always Reliable Service

Our heating system was not working. We called for an appointment. We were notified early morning that a tech was coming to help. The service for our heating system was done by Koi P. He was professional and advised us of all the issues we may have. He got our system to work but advised on what our options are moving forward as our system is 10+ years old. We used TE certified for our plumbing, electrical and now our HVAC system. We moved to GA from NY over 2 years ago and would recommend TE Certified for all our home needs!

Charles Mays came to my house to repair a plumbing leak and replace parts of my water lines all in my crawl space. He worked hard all day. He was courteous and professional and got the job done. Then he gave me a walkthrough and showed me everywhere he had worked. Didn't get that from other companies. Very satisfied.

The customer is replacing the GFCIs in his kitchen and shut the main breaker off and could not get it to reset. I was able to turn the breaker off then back on restoring power. I also corrected the switches located right of the sink due to improper wiring.

For this job, we installed three new kholer high line ark toilets. We removed all of the old ones, and took them with us. We also noticed two broken flanges one in the upstairs bathroom, and the other in the half bathroom. We replaced both with new flanges, and secured the, to the floor. The customer also wanted a pedestal sink removed, and a single vanity installed. We removed the old pedestal sink, and cut out the base mold for the new vanity to be flush to the wall. We secured, and caulked around the new vanity. The last thing we did was install two new lav faucets, and pop ups in the upstairs guest bathroom. We performed work, tested everything, and cleaned up. Thank you for choosing TE Certified.

Add two return ducts, one in the guest room and one in your sons room. This will give the system the air it needs to breath properly and increase the comfort in those rooms New drainline down the side of the house. This will remove the upstairs drainline from the main floor systems pump. this will increase the life span on the main floor pump and decrease the chance of flooding the basement.  New properly sized supply plenum. This will drastically fix the airflow upstairs and make the system be sealed properly.

Draft inducer motor has failed, inspected heat exchanger with digital camera due to age found crack @ 2 o clock showed client findings and took pictures will attach to invoice. Tagged furnace unsafe due to potential carbon monoxide fumes. Inspected heat pump found condenser fan motor running but compressor not energizing upon further evaluation of system found failed duel motor starter on compressor out of warranty. Due to condition of equipment and furnace being tagged unsafe scheduled install supervisor to give options on updating. Left repair options as well but repairs would be a band aid.

I was called out to Felix & Blanca‘s house for a heating issue. Upon my arrival Felix let me know that the thermostat was constantly heating the house well above what they wanted it. During the evaluation we discovered the thermostat was reading well below what the actual temperature was causing it to heat well above where it was actually set to. I adjusted the calibration it it didn’t get to the correct temperature so I contacted ecobee and they confirmed the thermostat was malfunctioning. We also saw that the flue pipe is outdated and installed incorrectly.

Arrived on site to troubleshoot flickering lights in the office. I checked voltage at main panel and outside equipment. Voltage coming in is steady and correct. I checked connections at the main panel and outside equipment. Everything is tight with minimal corrosion. They do have a power back up they were using. Once they unplugged that, the flickering lights stopped. I recommend investing in a new battery backup. I also recommend getting the power company out to test their wires. I did recommend install surge protection for all electrical panels in the office. Everything is working upon departure.
