Knoxville, TN, HVAC Company and Plumber

One of two units is currently nonfunctional. Non-functioning unit is almost 30 years old and is a 3 ton gas package unit. The condenser fan motor will not run, even with capacitor testing perfectly. Customer was present, presented options to replace condenser fan motor as well as Goodman and Armstrong Replacement options. Customer will need to weigh options overnight.

Unit has a lose connection to the capacitor for the compress, causing a failure to run and the compressor to produce a loud buzzing noise. We resolved the wiring issue, and the unit started up correctly and is operational.

Install attic fan

We made a minor duct repair that required fixing the tape joint and putting the furnace doors on correctly that was bleeding air into to the attic. The issue is resolved at the Furnace, as for the condenser, it is original to the house, but it is still operational and in decent shape. The unit is operational at time of the visit.

For this job, I replaced the condenser fan motor with new universal motor. System was tested after completion and is cooling

Unit is operating correctly with no issues, I checked the air handler, other then the AHU dose need the blower wheel cleaned and the evaporator coil is starting to get dirty. Over all the system is running at capacity with no issues detected at the time of this visit.

I replaced the failed Rheem system with a new Armstrong air system with a new aux heat kit. I also replaced the high voltage electrical with new, and pulled new high voltage wire. The new system is operational in all modes. I changed the T-stat programming for the reversing valve to energize into cooling. Return air 79.4F, supply air 64.6F, and delta T 15.2 F and rising as the space cools down.

Customer had leaky condensate line at the furnace. This has been capped off with an added 90 to make it easier to unclog in the future. Leak had fried furnace switch below it technician used customer supplied switch to replace the faulty. One unit has been tested and is cooling using new switch and condensate line.

I diagnosed a 10-ton shop Trane system with multiple repaired leaks. The compressor is locked out, and all oil is empty inside the unit. I installed a new outside Trane commercial 10-ton condenser unit with a 5-year parts warranty, a 10-year compressor warranty, and a 1-year labor warranty. The indoor unit is 10 years old and is in proper working condition. I performed a pressure test to 350 psig for 20 minutes, and the system held solid at 348 psig with no leaks detected. I pulled the system to 458 microns, which held for 10 minutes, indicating no leaks detected under vacuum. The unit is operational in cooling mode.

2006 rheem replacement defrost control board We replaced the defective defrost control board with an OEM Replacement board and sensors. The board responded correctly to a cooling call. And the unit is currently operational and cooling. Main level cooling is functioning. Return air 83F Discharge air 66F Delta T 17F The discharge air temps and temperature differential are with in tolerance for the age of the system and current return air temperature. Its will take a few hours for the temperature of the house to get down to the customers desired set point.
