Upon arrival, I cycle system in cooling and checked static pressure. I closed several vents on first floor and installed two magnetic vent covers. Static pressure did not change during adjustments. System is operating appropriately at this time.

Wrapped supply plenum. See internal notes. We will need to come back to perform quality assurance. Customer wants to follow contract notes quality assurance two weeks after installation. During today’s visit all we is wrapped supply plenum.

Installed Trane air handler and coil in 30x30 pan. New return drop with 413 filter box and new supply plenum. Installed UV light, EZ Trap, wet switch, blower motor surge protector and condensate pump with new vinyl to sump pump. Adapted to existing gas line and smoke pipe. Installed Trane AC. New 7/8” and 5/16” line set. New pad and rectorseal. Installed Rheem 50 gallon water heater with st5 expansion tank. New shutoff valves on cold and hot side. Ran new 3” vent. Tested out all operations and cleaned work area. Job is completed.

Recovered refrigerant in system: Weighed 16 pounds 9 oz. This s more than double what the system needs, Evacuated system to below 500 microns. Charged sustem factory charge 7 pounds 9oz plus what is needed for. 32’ line set. Total charge 8# 3oz Installed T6 wifi thermostat Installed wet switch. Afterwards tested system operations. Pressures 140/178 4 SH 2.5 SC with outdoor temperature 63°. Also forced test mode using outdoor control. Also verified no temperature drop across filter drier. System operating well at this time. Collected balance.

Winter bills are $900+ 2 months of every year. She has already addressed home performance issues. EIE joist sealing, attic insulation etc. Bosch 3 Ton with Space pak high velocity air handler. 7.5KW heat kit. Thermostat has no input for outdoor temperature. Left estimate for smart thermostat. Filter sizes (1) 14x30x1 second floor ceiling grille (1)14x20x1 first floor wall grille She mentioned that she had another contractor out and with the advice of Bosch tech support and they they charged the system… This was late December early January I enabled accelerated heating/cooling at outdoor control, disabled adaptive capacity. Temperature split 17° in cooling. Put guages on system. Head pressure was 534 psi. Subcooling 84° Cycled system off then back on. Head pressure gradually climbs. To 500+. And will instantly climb and shut off on high head pressure, Called Jeff Porter from Bosch who told me to measure across the TXV itself with thermocouple. 48.3-29.3 (

Performed tune up on Amana ac’s, checked indoor blower motor and checked and cleaned drains and tested temperature split. Changed both filters and checked outdoor units compressor and fan motors. Tested refrigerant levels and tested capacitors and checked all electrical and mechanical components. No issues with either unit at this time.

Performed precision a/c tune up on Bosch heat pump system. Replaced 16x20x4 air filter ( homeowner provided). Checked all electrical connections and components. Check temperature split. Cleaned out easy trap. Recommended installing wet switch in case of water leakage to shut down the system. Installed wet switch. Checked all the readings on Bosch heat pump system. Check refrigerant pressures and temperature at indoor and outdoor units. System system is working fine at time of service.

Completed (2) Heat tune ups First floor filter ok Aprilaire 413 Replaced second floor system filter 16x25x1 Completed humidifier service for basement system: New Aprilaire 35 water panel. Humidistat was set to maximum setting when I arrived. It will run constantly when there is a call for heat this way. Opened bypass damper, ensured drain was clear, water flow is set correctly. For BOTH furnaces: Inspected burners, heat exchanger, inducer assembly; burners for first floor system can be upgraded to stainless steel. Left estimate for this. I cleaned them today but they can become corroded enough that they need to be replaced. Second floor burners are stainless. In very good condition. Cleaned flame sensor, verified flame rectification circuit Ignitor in good condition verified ohm reading Confirmed proper gas pressures Inspected wiring and controls Measured temperature rise and static pressure Combustion and draft tests: Pass Both systems operating well at this time.

Wired transformer from EAC contacts to power humidifier contacts during heat pump operation. Tested afterwards. Went through humidistat operation with Cymon. Cymon had attic insulation and basement air sealing work done a year or two ago.
