8-12-25 Luis perform heat pump AC side inspection checked electrical components low and high voltage inspect all connections replaced customer supply 313 filter flush condensate drain inspect termination for proper drainage. OK check supply return air temperature. Ok check outdoor unit electrical capacitor, contactor ok check refrigerant pressures found to be 4.5 sub cooling provided estimate to a refrigerant and dye customer Decided to add refrigerant for now. After adding refrigerant pressure came back to standards with good sub cooling and superheat (see photo). Cycle heat pump ok.

Fully assessed no cooling situation. Found system locked out on ( refrigarant pressure error). Talked to homeowner and asked her how long she left the breaker off after resetting she said about 1 minute. Explained to her that with these mini split systems you have to turn off breaker for a full 5 minutes to reset any error codes. After I reset the breaker. Everything came back on , both outdoor fan motors were running. Checked temperature split both in attic at ducted air handler and ductless head on first floor both were running at a 19 degree split. Explained to homeowner that when you get a bad storm and there is a good chance the system would need reset after words. Heat pump is working properly at time of service.

7/29/25 Tan & Joe Returned to diagnose insufficient cooling for second floor. This has been an on going issue since installation where first floor gets cold and second floor stays hot. Remote sensor for second floor kept dying shortly after changing batteries (1.5 week according to clients). System ceases to operate when remote sensor dies. They asked us to remove it and we did. We unassigned it from the system. We checked velocity and cfm at second floor registers and they were lower than normal. Upon checking basement system we found supply plenum was halfway detached from the supply trunk due to duct tape losing grip. Supply trunk is duct board. We reapplied tape and triple sealed it so it doesn’t come loose so easily. Also sealed gaps in between furnace and return drop at the return base. Changed filter supplied by customer. Rechecked velocity and cfm and it improved slightly. Also checked attic insulation and found no immediate issues. We checked configuration and changed minimum

Hung mounting bracket for mini split head on wall. Drilled hole from interior wall to exterior wall. Hung new mini split head on wall. Ran new lineset from indoor head to outdoor unit. Ran drain line for mini split head outside and checked for proper drainage. Wired new mini split head. Set new unit on new pad and leveled. Hung new rectorseal disconnect box on wall. Installed new 15amp double pole breaker and ran new 12/2 wire outside to disconnect box. Hung new slim duct on side of house sealing penetrations. Flared and made all lineset connections outside in slim duct and at unit. Pressure tested unit to 366psi and soap bubbled all joints. Waited 30 minutes for tightness test before hooking up for vacuum. Evacuated system. Made all electrical connections at outdoor unit. Released charge and performed all test out procedures.

7/17/25 Tan Performed ac maintenance on 7 year old heat pump in basement. Filter was replaced by client the day before. Checked air flow, temp split, and amp draw on motor. Checked coil condition and found it good. Tested drain pain, line, trap, and pump. Cleaned dirty pump and tested. Checked indoor wiring and found everything tight and secure. Surge protector found on computerized blower motor and it is operational. Checked outdoor unit and found good refrigerant levels. Capacitor is in good shape as it is a year old, replaced last year. All electrical components are good, no mice nest found. Outdoor unit has computerized fan motor with no surge protector. Coil is clear with no signs of restrictions. Provided solutions to protect outdoor equipment and flood protection for basement. Client declined to review but we will save on file for reference. System is operational at this time

Found drain pan melted brittle and falling apart. No temporary fix will work. Let our office know and they are looking into a high temperature pan for this application. Our office to let homeowner know when we return with materials needed to complete the job. Homeowner would like coil raised off of heat exchanger.

Fully assessed temperature differences between 1st and 2nd floor. Made some changes to the system increased cam per ton from 400 to 460. Changes total cfms from 2000 to 2100. Changed compressor speed from factory to 40%. Also checked room temperature on first floor and found it to be actually 3 degrees cooler in the room them what the temperature was reading. Made a temperature correction by - 3 degrees. Homeowner will let us know if these corrections help.

Estimate

I arrived for a no cooling. I went to the downstairs system. I Checked the air filter and found OK. I went and opened up the indoor coil door and found the indoor coil was completely iced up. Blower motor was ok as well. I talked with the customers and I recommended having an estimate done for a new indoor coil and outdoor system. Dillion is scheduled tonight between five and six to give the customers an estimate on a new AC system. At this time I collected for $99.00 diagnostic.
