10/27/25 Tan Performed QA inspection on gas furnace installed by us on 10/21/25. Client is mostly happy with install however he questioned why it ran for 30 minutes to go from 72° to 74°. I found airflow settings for 2nd stage was set too high and the temp rise matched the 1st stage. I set it from F05 to F02 per recommended settings. Also set AC airflow from F08 (1554cfm @ .5” wc) to F04 (1401cfm @ .5” wc) for 3.5 ton system. Tested temp splits, combustion, and amp draw. Combustion was good so no need to adjust gas pressures. Flue pipe had to be installed away from pvc piping to prevent melting but otherwise ok. Ductwork is sealed well and wiring is tight and secure. System is operational QA is a PASS

Set new furnace under existing coil. Built custom transition from furnace to coil. Adapted existing gas line to unit and leak checked. Remade all high and low voltage connections to unit required all safeties. Adapted smoke pipe to new unit. Performed all test put procedures cleaned all work areas and reviewed installation with ho.eowner.

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.

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 (
