Completed AC tune up for 5 Ton Bosch inverter system Homeowner recently replaced filter. Indoor and outdoor coils in good condition. Inspected wiring, controls, electric motors and components; left estimates for surge protector for indoor blower motor. Outdoor equipment circuit has surge protector. Enabled accelerated heating and cooling at outdoor control. Measured temperature split and static pressure Inspected drains; cleared EZ trap, tested pump. Gave Fred some pointers about how to keep drain and pump clean and how to brush out EZ trap. Checked integrity of compressor motor (mega ohm test) Left estimates for Indoor air quality improvements He can do either (1) Single UV light above indoor coil Or (2) APCOX whole home air treatment (installed on return drop) WITH remote bulb above indoor coil. More comprehensive Relative humidity high in basement. Left estimate for freestanding dehumidifier. Will need condensate pump, we can pump to same place as AC drain pump termination p

Main lobby system calling for cooling. Indoor blower motor running. Found core sense locked out on “locked rotor” 45/5 capacitor failed. Replaced under limited parts warranty. Invoice includes diagnostic and replace run capacitor under warranty.

PECO Air Sealing and Insulation Project * Perform blower door test and calculate target for the home. * Densepack garage ceiling filling each bay with insulation to achieve the highest R-value possible. * Install 2” Closed Cell Spray Foam to air seal and insulate sill plate and rim joist cavities. * Perform CAZ testing including draft testing of appliances and combustion testing under worst case conditions. * Perform test out blower door test to validate results from air sealing. NOTE FROM INSTALLER: over 10% airflow reduction achieved; $75 air sealing incentive added to invoice. Customer is financing invoice balance.

They had turned off the breaker when they saw water on the floor. I checked for any open safeties and pressure switches. All switches closed. O fault codes on control board. I turned breaker back on. I did have to peas the “TEST”; button to get 24V to contactor. But afterwards I cycled system back off and on from thermostat. I tested pump and added some treatment tabs to pump. Temperature split 20° (81-61) Charged diagnostic fee

Estimate

System was very low on refrigerant. 5 Ton Coleman AC outdoor unit installed 7/29/23 with indoor coil that was installed 4/9/25. The evaporator door label is from the old R22 coil. I took a photo of the sticker on the actual Aplate of the new coil. Lineset 1 1/8” suction, 55-60’ Running at 61 psi. Found leak at braised joint, suction line service valve. Offered to isolate outdoor unit unsling service valves, recover, fix leak while purging with nitrogen, pressure test, evacuate, Then open service valves and charge system. Completed work as above. Pressure test held 300 psi for 15 min after. Bubble tested new joint and all joints. Evacuated to 495 microns. Opened service valves, Charged system. Final pressures 134/300 12.5° SH 11° SC. Final temperature split measured at equipment. 78-60=18° Perfect. System operating well at this time. Took photos and dimensions of funace 21” wide, 28” deep 34 1/4” tall. On 1 3/4” cinder block. Condensate pump with safety. No wet switch, 90% Reuse

Found L6 error code at outdoor unit. Open start winding. Checked wiring harness. Checked compressor ohm values between windings. Megaohm test Pass. 35uF capacitor was reading out of tolerance. 38.8uF Adding a start kit or capacitor alone did not resolve issue. Need both start kit and new capacitor which is covered under parts warranty. Afterwards tested system operations: Ran system for 15 min. Pressures were 124/249 33SH -.03 SC… Temperature split was 12° (78-66) system is low on refrigerant. There are no leaks at brazed joints. Offers to charge system up to 2 pounds R410A and add a leak detection dye. He agreed. Charged and added dye today. Final pressures 132/263 10.6 SH 3.3 SC Good Final temperature split 76-55 = 21° Good System operating well at this time. Now had refrigerant leak detection dye which will help us determine where leaks are. Ben paid for invoice today.

7/9/25 Tan and Nathan Returned to fix recessed ceiling light fixture back into place. Used a giant 20ft A-frame ladder and placed light fixture back into place. Light is secure and does not slip out. Also checked the light fixture next to it for customer satisfaction. Both lights are secured and back into place.

Estimate

Fully assessed no cooling situation. Homeowner had a power surge the a few days later system quit working. Found 240 v going to 75 va transformer but no 24 v coming out. System is a split climate master geothermal. Replaced transformer with 50 va for now. Customer signed up for maintenance plan. Will need to return with correct 75 Va transformer and install at maintenance visit. After replacing transformer tested out system air temperature split was 20 degrees. System is working properly at time of service.
