3/20/26 AC tuneups on 2 ducted Minisplit air handlers and one ductless head minisplit. All 3 indoor systems connected to one outdoor. Outdoor fan motors are not running. Hear compressor starting. Found standing pressure when hooking up gauges. There is voltage going to system. When I first pulled off door found board throwing code 11. Technician to return to diagnose issue 3/20/26 Dan I arrived to look at two ducted, mini split air handlers and one ductless head and an outdoor mini split heat pump for not working properly. First thing I did was check each indoor individually check air filters cleaned and replaced. Ran the systems in heat mode and had great temperatures for both systems and the outdoor was running fine. I made a call to Mitsubishi and talk to tech-support I gave them the model and the serial number of the air handlers in the outdoor and they told me that this system needs to be above 67° to run AC, I believe we’re going to hit 70° on Sunday. I had told the custom

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

Luis 3-12-26 customer called in for error message on thermostat, suction line temperature sensor out of range. I check system operation check all sensor and compare with manufacturer data, found suction line sensor is outside range. We need to come back with correct suction temperature sensor. I would also recommend doing tune up on system. Replacement of suction line temperature sensor Customer paid full balance . 3/17/26 Dan I arrived to the customers home to replace their warranty outdoor suction line sensor. I turned power off to the thermostat and the outdoor inverter. I removed Luis temporary line sensor and replaced with new OEM suction line sensor. I turned the system back on and tested. Everything is working fine at this time of service. I asked the customer if he wanted service on his equipment, not at this time . Paid in full previous visit.

Luis 3-16-26 customer called in for no operation from the unit blank thermostat and unit does not come on at all. She recently had some work on on ductwork, they worked on unit and now unit does not come on. I checked system operation found neutral wire (transformer) disconnected from board. I connected terminal and unit came on test blower operation I do not hear any noise. Noise was probably addressed and during fixing the issue. The neutral wire came loose and got disconnected from terminal block. I noticed unit does have any surge protection, unit has float style water protection, I provide estimate to add these water safeties.
