Completed QA for Trane heat pump 3 Tons with 10KW electric heat kit. Filter size 24x24x1 and a 12x12x1 in the basement. Inspected all aspects of install. Made following changes to Thermostat configuration: Minimum system speed Factory>40% Minimum CFM/Ton 400>>350 Max CFM/Ton 450>>370 Minimum indoor coil temp 32°>34° Changed heating and cooling from more comfort to balanced. Enabled AUX heat lockout and set to 38° Set power monitor over-voltage to 257V, open in .5 seconds, Restore power after an event after 180 seconds. 10KW electric heat amps 40: Good Measured temperature split(70-50=20) Good Verified refrigerant charge using test mode: Good

Sunday night 9 pm Luis 9-14-25 customer called in for no cooling upon arrival found up indoor unit running but no outdoor found manual high pressure switch open, reset switch and test operation, check refrigerant levels and pressures, inspect indoor and outdoor coils. I was able to find some signs of dye on indoor coil and outdoor coil as well. Provided estimate for repairs. Would recommend getting an estimate to replace system, customer will need to do repairs or replacement to maintain system working properly. Emailed estimate for repairs. Home comfort consultant to come to provide estimate on a new system.

Homeowner had condensate pump safety issues starting about. 2 Weeks go. Ultimately replaced his own pump. When I arrived today. Found blown 3A fuse. Checked for any shorts. No shorts determined. Replaced 3A fuse Still no LEDs on board. 24V at transformer Made estimate for. New control board under parts warranty+surge protector Homeowner agreed collected for Plan membership renewal PLUS half of the cost of the estimate. Today: 488.16. We will collect balance once work is completed. (299.15) Control board is ordered by our warehouse. We will contact them to schedule as soon as board is in our hands. I also used ECM motor tester to make sure blower motor module is not shorted and powered the thermostat with 24V from thermostat. Thermostat display: Good. There is still a chance that one of the thermostat contacts is fried or shorted. We will determine this once control is replaced.

Installed new Trane TAM air handler with Trane link thermostat and 10 kw heat kit. Adapted to existing electrical and metal. Installed unit in 30x60 pan. Installed EZ Trap, wet switch and blower surge protector. Installed new Trane 3 ton heat pump. Installed on 8” snow legs and new pad. Installed rectorseal power monitoring disconnect. Replaced lineset and reused line hide.

Ducted Mitsubishi Minisplit. Attic Drain pan was full of water. 14x20x1 filter clean (MERV11) Float style safety switch shut equipment down. I used wet vac to remove water from drain pan…approximately 15 gallons h20. Made sure switch contacts closed. Cleared drain line with c02 gun then water as well as using cable tie to clear trap. There is no clean out at coil port and trap is difficult to clean. Left estimate for EZ trap with clean out and float style overfill protection switch. Also added a few rubber pads at a point to give proper pitch to the drain. Rewired system. Had to reset breakers and wait full 5 min before restoring power. Allowed system to run 10 min, Temperature split and refrigerant pressures Good System operating well at this time. Krissy approved repairs and allowed to charge card on file for invoice. Locked both door of area and placed key in envelope where it was when I got here per Krissy request

Est

Home inspector told her she needs to clean outdoor coil. Offered tune up and clean outdoor coil. 4Ton Lennox heat pump: 2 zones Ariel zoning Basement and Upstairs. Cleaned outdoor coil, includes disassembly of all hardware to access all (4) sides of coil. See uploaded photos of before and after. Ran system for 12 min after coil cleaning to allow refrigerant pressures to acclimate. Completed AC tune up: Replaced 20x25x1 air filter Indoor coil in good condition. There is a UV light system installed in supply plenum. Inspected wiring, control, electric motors Checked drains. Measured temperature split. Refrigerant pressures indicate slight undercharge of refrigerant. Subcooling is 1.7°. Target is 5° based on manufacturer chart and indoor coil matchup. Offered to charge system. She agreed. Added 17oz R410A refrigerant. Original pressures: 262/114 16°SH 1.3°SC Final pressures 274/112 14°SH 4.8°SC System operating well at this time. Homeowner paid for invoice today,
