Fantastic HVAC Experience

I had such a great experience with Albert. He was incredibly kind and patient, and really took the time to help me understand what was going on with my HVAC system. He walked me through the issue, answered all my questions, and helped me figure out the best fix. The full repair is scheduled, but I feel completely confident in him and his work. It’s rare to find someone who’s this knowledgeable, professional, and easy to work with. I’ll definitely be using him again and highly recommend!

No Heat - Upstairs System stopped working after duct cleaning yesterday. Observed that the flood protection switches were tripped and there was no water present. The flood protection switches have failed. Homeowner approved replacing both flood protection switches. After installing new switches I tested them both and they are both operating properly. Checked heat exchanger and tested equipment. System is operating properly at this time! Thank you for choosing T.E. Certified, have a great day and happy new year!

Jennifer Carter is out to her home today to replace her ceiling fan in her living room. As replacing the ceiling fan, the ceiling fan is not on a fan rated box. So today we replaced the ceiling fan and installed a fan rated box.

Picked up the material from Apex Supply Sandy Springs and Johnstone Sandy Springs. Arrived at the customer’s home to complete quoted repairs. Removed the failed UV bulb for the upstairs Apco-X. Tested operation to ensure it functions properly. Open up the coil compartments for both the upstairs and main floor systems. Cleaned both coils with evaporator coil cleaner. Also treated the coils with Bio Fresh. Reported results to the customer.

For this job I came out and replaced a pop up assembly for a vessel bowl sink. I informed that the vessel bowl wasn’t installed properly and that it needed to sit on a ring mount and the hole in the countertop sink was too big and could not secure the bowl properly. I replaced pop assembly and re silicone the bowl to the counter top but informed customer the seal will break again. Checked and tested for leaks, conducted a super cleanup.

Arrived at the customer’s home to find the cause of a “mildew smell” coming from the vents when the system was switched to cooling, particularly on the main level. The customer found that the upstairs Apco-X had a fault and had a solid red LED. Found that the bulb for this upstairs UV light was broken and would trip a fault code after sparking. The UV lights both are high voltage model Apco-X Ultras which are more prone to faults than their low voltage counterparts. No issues were found with the main floor system at this time, it is possible that the main floor is pulling air from the upstairs and causing a stronger smell with a stronger blower motor. While fixing the issues with the upstairs system, both coils can be treated for odors using bacterial treatment chemicals. It is recommended to change the high voltage Apco-X Ultra for the upstairs to a low voltage Apco-X Ultra Dual model with a secondary UV light in the coil compartment. Reported results to the customer and scheduled to

Customer had a leak on ceiling in downstairs hallway and after further investigation we found that the upstairs toilet was leaking from the bolts. The water traveled down the wall into the Sheetrock in the downstairs ceiling. We replaced the toilet with a 12 inch rough kohler helmbrook with a new wax ring and new closet bolts. After replacing it we cleaned the area thoroughly and left a clean area. We also wasn’t able to take a picture of the water heater because homeowner was not home.

Customer called us out for a backed up drain in the basement shower. I inspected the bathroom and the sewage ejector pump. The ejector pump had water on the lid but no obvious leaks. The shower was not holding water anymore. I bypassed the float by plugging in the ejector directly. It worked and took awhile to fully drain. I then plugged the float back up and ran water in the shower till I heard the pump go off 5 times. Issue seems to be resolved.
