Estimate

7/8/26. Fully assessed no cooling situation. Found thermostat was going blank every so often. Went up in attic and found dirt in drain line that was causing the ez trap float switch to shut off the system. Tried calling several phone numbers to get a hold of someone to talk about the clogged drain line this is not covered under warranty our office to bill out. Cleared drain line.

7/7/26 Installed ZapPro surge protector at outdoor equipment contactor inside service panel. Installed VZPro surge protector for indoor blower motor. Replaced REME air cleaner cell. Tested system afterwards Aprilaire 413 filter Good Temperature split 21° System operating well at this time. Homeowner paid balance today,

7/2/26. Fully assessed no cooling situation. Found after talking to homeowner that the indoor blower would not run but the outside a/c would continue to run. Found a B4 and B6 error code in the history. This is a blower motor not communicating with circuit board code. This code can be caused by low voltage coming in causing a communication error. Voltage coming into furnace is very low at 112v this can cause communication error due to the high demand of everyone running there a/cs. Told customer all you can do is try to reset it until the demand goes down if the problem still occurs we will need to see if it’s a board or blower motor. System is working properly at time of service.

6/13/26 Dan I arrived to the customers home to look at his single mini split system in the kitchen. The customer had mentioned they had a good storm surge on there system and other items in the home. The mini split has 240 volts at the head and at the outdoor. But nothing is responding and have no lights . I have good standing pressure at 217 psi. The single head and single outdoor heat pump is near 6 yrs old. I had told him that it might make more sense to replace the whole system with new . Because if we replace all the boards there is no telling if that compressor and fan motor didn’t take on damage from the surge as well We can price out the boards for him but highly recommend replacement. I collected for my diagnostics. The office will follow up on Monday.

6/13/26 Dan I found the Customers expansion tank was waterlogged. I quoted the customer for a new expansion tank. He agreed with the pricing. I drained a little bit of water out of the water heater and removed the failed tank. I prepped the new tank and set pressure 70 PSi. When vacuuming the water out of the pan, I still saw water seeping from the water heater into the pan. The customer will monitor the rest of the weekend may just be residual water from filling the pan originally from the expansion tank failure or the jacket may have a rip in it, which will compromise the water heater, I did take pictures of the customers warranty paperwork office will look at it on Monday and we can find out if the water heater is actively leaking or if it was just residual water from the expansion tank, but i collected for the expansion tank replacement and diagnostic . Total due $482.23 paid by check # 12945 I did leave an estimate cost for a new water heater .
