Came out today to perform one system HVAC service call. Upon arrival, customer stated that he had already had a previous technician out and that the unit was running when the tech was there after not running all night and then quit running again after the tech had left. Upon inspection of the unit found that the system had no power, this was due to the disconnect being melted due to a loose wire. Upon making repairs, started the system up to ensure proper function. Upon start up, system was running fine. Upon further inspection, found the blower wheel to be clean. All heating elements working properly. More further concerns there was no bypass damper, there was no UV protection, and no TE standard flood protection for the system. Also, there was no transformer for the zone system, all working off of one transformer. At this time customer chose Band-Aid repair option. System is up and running see estimate for further concerns.

Came out to a no heat call. Performed a full diagnostic on 2024 carrier heat pump. Checked all components in air handler, they were good. We checked the filter and the delta T and they were good. they didn’t have TE standard flood protection, they didn’t have any IEQ. checked the heat pump outside, checked the pressures and temp on suction line they were all good. Checked the components on outdoor unit and they all were good. Ran the system for 30-35 min and the system is running according to specifications.

Tech diagnosed mini split and notice normal R-410a pressures while system in operation heat mode… system was not heating up after 15 minutes of run time. Tech decided system had noncondensibles inside system. Tech left options to move forward with recovery and reclaim new refrigerant inside system. Customer wants to first reach out to manufacturer and see if they may be any other options before moving forward with repair… Please review email, to respond to any estimates you can do so by email or calling in to reschedule appointments. *Thanks for choosing TE Certified if you liked your technician service today don’t hesitate to leave a 5 star review!

Our client reached out to us to have a water heater removed for the drywall crew, to hang drywall and repaint the area from a previous flood. Our client also had a sewer ejection pump that failed in the process, and would like to have both matters taken care of. The new pump is installed and was tested for leaks, and no leaks were found. The pump came was resealed. A client is going to schedule us back out in a couple of days to reinstall the heater after all painting is finished.

Internet company hit the main water line when they were installing the internet and they improperly repaired it which is what caused it to leak slightly. Properly repaired the main water service line in the front yard.

Replaced water heater, Prv and installed new water heater shut off. Also we replaced the single wall vent with double wall vent and insulated the water lines to bring everything to code. The homeowner did also have a sewer backup which resulted in water coming out from the base of 2 toilets which was from when the homeowner was running the water to release the air from the system. I recommend they reach out to a septic company to inspect the septic tank/leech field.

Cut open drywall ceiling to search for compromised sections of 3/4” cpvc piping. Found sections of pipe that are stretched beyond the original manufactures design. Suggest repiping sections of waterlines with new piping.
