Turn power supply off to Air Handler. Disconnect and remove blower motor assembly and blower housing. Remove the failed blower and install a new Blower Motor and Mounting Bracket. Align blower wheel and reinstall the blower assembly. Complete electrical connections and put system into operation to test. 3/28/25 Replaced failed blower motor. Cleaned blower wheel while I had it disassembled. Wired and tested afterwards. System operating at this time. *I did turn on AC to make sure it is operational however because the steam coil is filled with steam I couldn’t truly assess refrigerant pressures.

Customer is not present at time of completion of job, payment was not collected. Replaced attic air handler system Trane 3ton r454b system. Installed 10kw heat kit. Flushed and reused lineset. Adapter to existing drain. Added an ez trap on the system. Adapted to existing metal. Also installed a blower motor surge protector inside unit. I have to convert the air handler from horizontal left to horizontal right. Charged system with 1lb 5oz of r454b refrigerant. Installed 3ton Trane heat pump on a new pad and snow legs. Installed new disconnect and whip. Tested system in all modes and uploaded photos.

Installed new trane 80% gas furnace and A/C outdoor. Reused return and supply. Tapped/caulked return and supply. Adapted gas line and flue pipe. Adapted high volt and installed new outlet and switch with surge protector. Installed new condensate line with ez trap and condensate pump. Ran new vinyl tubing from condensate pump to sump pump located in basement. Installed new t6 Honeywell thermostat and wired in low volt with safeties. Flushed existing line set and adapted to new equipment. Installed new trane outdoor on leveled pad. Installed new disconnect with surge protector and wired up to outdoor unit. Cleaned up work area and tested out equipment

AHU#1 No heat 0 volts at blower motor contactor coil when there is a demand for heat from the thermostats/controls for this AH. The contactor coil is intact and reading correct ohms. Line Voltage is present at contactor and manually pressing in results in blower operation normal..no shorts or faults. I physically traced out the low voltage wiring circuit there is a C02 sensor that has a green LED. There are no wiring schematics for the BAS or control circuits. difficult to troubleshoot. Not enough info. Freezestat contacts are not open. I reset and made sure contacts were normal. The BAS system as installed 8/12/20 Handwritten note on back side of front door of BAS controls reads “Start Up 8-12-20 KH” AH#1 is still down. and then call contractors who installed BAS.

Heat tune up for steam coil air handler with 1.5 ton R22 AC: Replaced 14x20x1 filter. Last replaced 7/2022 very dirty. Blower motor has failed. A universal motor will not work because of air handler size and mounting hardware. We will have to order correct size motor and charge accordingly. Our office will provide estimate when pricing and availability of motor is determined We made sure there was refrigerant in system. Equipment is 24 years old. The room is still maintaining temperature because steam piping is in adjacent mechanical room. There is also a space heater in the living space. Left power off to air handler.

Completed heat tune up for Minisplit with (4) indoor heads. Cleaned all washable filters Snaked drains at 2 of the problematic indoor heads, blew drains with C02 gun and added water to test flow of drain water. Measured temperature split at each indoor head. Verified refrigerant charge while running all indoor heads at high demand cooling: Good Inspected wiring, controls, and motors. Equipment has surge protector. Also tested system in cooling *Went to drain termination in basement and sucked with wet vac to ensure flow. See video System operating well at this time.

Completed AC tune up. 20x20x1 filter ok Measured temperature split and static pressure Indoor and outdoor coils in good condition Inspected wiring, controls, electric motors; left estimate for blower motor surge protector Inspected drain, Cleared EZ trap, added treatment tabs, Verified refrigerant charge/ Pressures System operating well at this time.

Completed (3) AC tune ups for Byers hall. Filters in good condition. Checked drains, traps. Inspected wiring, controls, electric, motors and components. As long as the hydronic heat pump from the pump room is running in the winter the (3) hydronic coils at the air handlers will be hot. So you cannot cool the zones in winter, the hydronic coil for the school store air handler has a thermostatic valve at coil stuck closed so it actually does have a lower supply temperature in cooling even when hydronic pump is energized. Checked refrigerant pressures and diagnostics. Systems operating well at this time.

Completed (4) AC tune ups All filters in good condition The 4 ton R22 system for main classroom very low on R22 refrigerant. We have provided system replacement options for this system. The 2.5 ton R22 system for back office is low on R22; the furnace for this system is newer. System upgrade would be for AC only. Cleared and inspected drains, added treatment tabs. Recommend EZ trap for2.5 ton system for back office. Also recommend wet switch for computer room system and the (2) R22 systems. Left estimate for (3) wet switches. Measured temperature split and static pressure Inspected wiring, controls, electrical motors and components. Checked refrigerant pressures and diagnostics. Both R22 systems low. The back classroom system has a kink on the suction line close to the outdoor unit. We have provided an estimate to repair this. Systems operating ok at this time. Strongly encourage upgrading the main classroom/conference area system.

Performed ac tune up on Amana air conditioning unit, checked indoor air handler and tested temperature split and indoor fan motor, tested and cleaned drain and went to outdoor unit and tested all electrical and mechanical components. Tested outdoor fan motor and compressor. Tested capacitor and refrigerant levels. Tested capacitor and electrical connections. No issues with unit at this time.
