Completed humidifier service: Replaced existing water panel with Aprilaire 35 water panel. Opened bypass damper. Cleaned housing. Verified feed water flow. Tested operations. Set humidistat to 35%RH. Tested system operations. Heat pump temperature rise 20° (65-85) with outdoor temperature 35°: Good. Provided email estimate for APCO X whole home air treatment system. The version with the remote bulb is not needed. Regular APCOX can be installed in box under evaporator coil. System operating well at this time. Homeowner paid balance today.

Completed heat tune uptune up for 4 ton Daikin invertersystem Replaced 25x25x electrostatic filter media. There was one on site. He has 1 left.

Provided estimate for blower motor surge protector and estimate for heavy duty surge protector for outdoor equipment circuit. Measured temperature split and static pressure Inspected drains; there is no cleanout for trap. There are no water safeties other than pump safety. Left separate estimates for EZ trap and wet switch. Also left estimate to do both together at a discount. Tested defrost cycle. Assessed refrigerant charge checked pressures. 320/116 Good There is a humidifier on system.

Fully assessed long runtimes for heating master bedroom. Went over data that homeowner had been recording of system. Found that thermostat off long runtimes to achieve temperature in the master bedroom mostly occurred around 36 degrees outside temp. Changed ballance point in arzel zone board from 35 degrees to 40 degrees lockout temp for heat pump. Also set some of the high limit settings back to default. Took measurements of master bedroom . Homeowner will let us know if these changes help.

Out for a QA on new gas furnace and ac with arzel zoning. Recall two days after install for drain line leaking (failed qa for this). Tested upper zone (#3) and verified temp increase with Dillon and customer. Satisfied in 10 mins. Customer is still getting used to new dual stage system and new zoning. systems working properly upon departure pics on file. Also added ecobee remote sensor free of charge off my truck per Dillon

The 3/4” pvc elbow just outside furnace was not glued. Water was dripping and caused the wet switch to shut down equipment. I primed and glued elbow and then we tested system. Mr. Lee showed the Ecobee report that this morning the master bedroom zone ran for 1 hour 10 minutes and did not satisfy demand of 64° and remained at 62,° First floor zone was not running at the time the master bedroom zone was calling for heat by itself. He decided to shut it off. 1St Floor zone satisfied in 25 minutes. Took photos of Ecobee reports from this morning. I tested the zones making sure the zone dampers are wired to the correct corresponding thermostats. Also checked temperature rise at the equipment and at the supply grilles. 67-89=22° Supply temperature for to 93° by the end of my time here. Master bedroom temperature raised 2.5 degrees while I was here in about 45 min run time. We made sure fan settings were all set to auto. Checked heat pump pressures. 98/268 R454B with outdoor tempera

Installed new Trane 90% gas furnace and heat pump. Built new return with April aire 213 filter. Adapted supply and placed indoor unit inside 30x30 drain pan with wet switch.

Installed new condensate line with ez trap and condensate pump. Ran new vinyl tubing from condensate pump to sewer drain in basement. Installed new arzeal zoning system. Installed 4 new arzeal zone dampers and tubing to make necessary connections. Installed 3 new ecobee lite thermostats and wired in safeties. Flushed lineset and adapted to it. Installed new heat pump, leveled pad, and put on snow legs. Installed a new rector seal disconnect and made sure calibration was right. Installed new outdoor temp sensor. Wired this with the extra wires on the outdoor unit. Cleaned up work area and tested equipment. Dillion had to finalize the financing paperwork.

10-20-25 Luis. Second opinion, customer has heat pump with propane heater as back up. Three zone system (infinity communication zoning system) I was able to locate all dampers. Two of them are tide together 8x24 motor on the 24. Other two for the addition part are 12x8 with motor on the 8 side. Both thermostats for the addition are 5 conductors and main thermostat has 8 conductors. Zoning system is not working it does not bring the heat. I test heater by jumping at the unit, heater came on and test operation gas valve makes loud noise. I also seen some water under the combustion removal system. I explained situation to customer and provided estimate to replace parts. And also new zoning system. Customer will decide what he wants to do and then call office. Due to age and condition would recommend system replacement.
