Vanity lights in master bath not working, once completed the troubleshoot we noticed grounds weren’t tied in, we corrected that issue and recommended a partial home Redevice to make sure devices are updated and connections were made

Performed diagnostics on the upstairs system. I found that the upstairs system has a furnace that is over 20 years old and is poor condition. The Upstairs AC condenser is over 20 years old and has a refrigerant leak. The system runs on obsolete refrigerant (r22 refrigerant). HVAC system needs to be replaced. The AC system has failed and maybe a water hazard to the home. The homeowner has setup a time with an install supervisor to get an estimate to replace the system. Mainfloor system: the drain line is clogged and I could not clear it with compressed nitrogen. The system need a new drain line. The furnace and outdoor unit are also from 2003 and needs to be replaced or atleast have the drain line replaced and have flood protection installed so further diagnostics can be performed. Customer didn’t want repairs done due to the age of the system and the amount of money already spent on the units.

For this job, we installed a new Prv and main shut off to the home. Once complete we checked for leaks and set pressure to 65 psi. We will be coming back to install the new garbage disposal and faucet once countertops and sink are installed. Thank you for choosing TE Certified.

Homeowner had another company perform maintenance. Homeowner stated after maintenance system didn’t run properly. I believe they came back and found leaking evap coil on main floor. Homeowner is contacting the original install company for warranty purposes. I did find leak at coil electronically and topped it off to keep the home cooling.

Properly Performed spring/fall maintenance on a whole home system. Replaced all filters checked blower wheels for built up dirt/dust, cleaned flame sensors, cleared inducer ports, tested hot surface igniters, took delta Ts, cleared drain lines, tested safety switches, tested all electrical components, tightened all electrical connections, took running volts/amps, monitored systems operations. Cleaned the condenser coil and renewed their membership.

Blanked thermostat due to wet switch activated. Reset wet switch and restored power to thermostat. System was little low on Freon. Added Freon to bring pressures back to normal. Xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx Failed inspection. Mini split condenser is too close to the wall, according to the inspector and need to be moved away from the house. Mini split head in the back room is leaking water thru the drain, and it was installed too close to the ceiling and can’t have access to check drain , neither filter. It need to be moved to other wall in the bedroom. Drain line outside was connected to the gutter , but it’s not downward and water is backing up into the mini split. Will have install crew to fix these issues.

Performed one system diagnostic for upstairs unit. Found unit to be 22 years old, R22 rusted coil, dirty blower, dirty filter, dirty evap coil, growth in supply plenum, failed run cap, failed dual cap, dirty condenser, pitted contactor, failing outdoor breaker. Due to age of unit and cost of repair would recommend replacement of system and joining homecare. Also recommended IAQ to improve air quality as well as an upgrade filter option. Unit is operational but not efficient. Based on our findings today, it might be time to think about getting a brand new system.
