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.

Our complete experience with TE was exceptional from start to finish. Placing the service call was easy and they responded in a timely manner. Once the technicians arrive (Cole and Chad), their professionalism was exceptional. Cole and Chad worked great together as a team. It's hard to find a service technician like Cole Dunn that has all of the boxes checked. (Customer Service, Strong Technical Knowledge, Professional Appearance, and Communication) This guy is one of a kind! I can't say enough good things about TE. Thanks for the great experience.

Today I came out and cut an access hole in the soffit in a spot the customer suspected there was a wire for a previous floodlight, and wanted a new one installed. I cut the hole and discovered there was no wire. I gave the customer estimates for other lighting solutions in this location but we did not move forward with it today.

Stacy called us out today because she had a circuit breaker trip. Upon arrival Stacy found a problem with a charging cube. I recommended replceing the outlet and install a dual function breaker. After she spoke with her husband mark we just replaced the breaker. We also installed a light above the stair way.

We came out today due to the Carbon/Smoke combo located in the basement area. The combo detector was sounding the low battery alarm. We took the battieres out of the unit and checked the voltage. The batteries volts were high 1.3 volts to low 1.4 volts. The homeowner gave us new batteries for the unit. The new batteries volts were 1.5 volts. We put the new batteries in the combo unit and the alarm stopped. We determined the lower volts in the batteries made the alarm go off. We supplied and installed a new duplex receptacle in the cabinet near the stairs going to the attic due to the existing device showing signs of heat build up. The breaker that controls the device is located in the main panel, bottom right tandem paddle “B”. After installing we tested the device and it is working.

Homeowner had attempted to remove the shower cartridge in the master bathroom. During this the cartridge broke off and was stuck inside the valve. I was able to remove it after several attempts and trying different methods. Installed new cartridge and tested. Homeowner had broken screw that holds the handle to the cartridge. I tested and verified all was working properly. The thermal expansion tank is ruptured internally and is no longer protecting the plumbing system. The water heater is 12 years old and I am recommending replacement.

Perform no heat on zones whole system unit. Found 4 foot bypass causing unit to shut off and go into lockout. Also found dirty, blower wheel, dirty, condenser, found coil, broken at aluminum connections, improper, flue pipe, no TE flood protection, found filter backwards, you also had high static pressure, all of the collars on the unit were non-insulated, also had supply for leaking air, control board, and zone dampers will need to be replaced as well as adding a smart bypass to help with airflow and static pressure. System is bypass to be controlled by main level thermostat at this time. We also have an install supervisor to come quote ductwork and possibly a full system. Replacement to get unit under warranty by TE. System is out of warranty and inefficient and cost of repairs are high. Based on our findings today, it might be time to think about getting a brand new system.
