Downingtown, PA

- Conducted an assessment of the first-floor system, which was not operational. - Examined and reviewed the equipment associated with the outdoor AC unit.

I arrived to the customers home to look at a noise on the outdoor unit. He said it gets too loud when it’s cold out I had told the customer it’s going to do that because it’s gonna ramp up and down due to outdoor temperatures. it’ll run at lower hertz and won’t be as noisy on less of a load day. There is no way to adjust the outdoor unit for noise due to the compressor, the way a modulates with the fan and the outdoor temperature sensors. He also was having a noise issue with his zoning and his family room for one of the vents. The zone is zoned 2 . I mentioned to the customer that this run out comes right off the top of the plenum above the coil so it’s moving more air then any other run out for that zone. I gave the customer two options option one is to remove or cap off that run out. He has two other run outs for the family room or we off that plan and flex to run out and extended down further on the trunk branch, I gave him two option prices for him to review. He would like to s

3/19/26. Fully assessed high energy bills situation. Found 2024 run tru heat pump system. Gave thermostat a call for heat. Found just auxiliary heat running at 40 amps. Their electric bill was around $1300 all winter. Found outside heat pump locked out on a code 4 hard lock out. Reset and checked 410a pressures they were 206/33. Low on charge. Found some refrigarant oil at indoor coil. Provided leak search option and membership plan. Homeowner is going to contact neighbor from here for now. Will possibly give us a call later on. Also recommend to homeowner to use a magnetic cover for air filter access.

Replaced air proving switch but ultimately determined that with new blower motor FAN ON speed there was not enough pressure in the air tube to make the switch operate so I installed a relay that will act the same way (close a switch and power relays) any time there is a demand for fan. Completed AC tune up Aprilaire 501 filter ok. Will need to be replaced at following tune up. Indoor and outdoor coils in good condition Inspected wiring, controls, electric motors. Equipment has surge protection Measure temperature split and static pressure. Checked refrigerant charge and pressures Checked drain System operating well at this time. Homeowner paid balance of invoice today. This AC tune up is included with recent install.

Replacement of customer supplied thermostat, red link thermostat for basement zone. Reconnected upper thermostat and basement test system operation ok set programming to heat pump, 3 degree drop. And 30 minutes timing for electric heat, system is working properly. No charge for dispatch.

I arrived for a second opinion for a heat pump not working correctly. When talking with Tim he was telling me that he had several techs out for the system not working from the start. He had multiple issues with the install from day 1 . When I was looking at the outdoor heat pump and trying to check the charge I could smell the acids from the unit . The system is definitely at risk for compressor fail or and other refrigerant components. The customer has an estimate scheduled this evening with Tony around 5 o’clock. I collected for my $99 diagnostics paid by credit card
