Issue is uninsulated ducts are sweating on top of new drop ceiling tiles. Happens on hot days. 2nd Floor Duct dimensions are 8x24” He has tried bubble wrapping it himself. It only sags. Ideally the cuz drop ceiling needs to be removed or taken apart enough to be able wrap what sections we can. Relative humidity was 62% measured by my psychrometer. I encouraged him to use his plug in dehumidifier but set to 50% or 55%. Which will help. Also replaced dirty 16x20x1 filter. I offered to do AC tune up, He has another company doing the AC tune up soon. I took as many photos as I could. I recommend site visit from management to give quote for wrapping ducts and installing dehumidifier.

Equipment is 3.5 Ton heat pump with 10KW electric heat kit. Homeowner explained that he had a company replace blower motor this past December. System is not zoned. 2nd floor remains hot in cooling season unless thermostat (on first floor) is set to target temperature 70°. Ductwork that is in attic for (2) second floor bedrooms is not sealed or insulated. *The underside of roof sheathing is insulated but there is no insulation in the bays under plywood. Homeowner may invest in insulating attic to modern standards, Took photos of attic and ducts that are in attic. Thermostat does not have input for outdoor temperature. Heat Unp drop was set to Comfort. I set to 3° which will control use of 10KW auxiliary heater a little better. Provo estimate to install Honeywell S1200 smart thermostat to be able to lock out electric heat when outdoor temperature is above a setpoint (40°) Completed tune up. Replaced 20x20x1 filter Indoor and outdoor coils in good condition Inspected wiring, cont

AC tune up for 5 Ton AC Equipment is hybrid propane furnace/heat pump installed last month 5/23/26. 20x25x4 filter ok recommend replacing every 3-4 months. Completed AC tune up for 3 Ton Amana AC system Indoor and outdoor coils in good condition Inspected wiring, controls, electric motors and components; left estimates for surge protectors. Currently has Nest thermostat. Provided estimate for Honeywell S1200 thermostat with EIM which will allow for more precise control of furnace staging and furnace lockouts in heating and allow for sensors and accessory wiring, *Cooling fan motor speed set to 450 CFM/ton. Black wire at defrost board is for bringing on auxiliary heat during defrost. Wired it in today,* they had already wired the white conductor between the outdoor unit and indoor control to the W1 terminal. Wired black conductor (X2) from defrost to white W1. Measured temperature split and static pressure Inspected drains; cleared trap tested pump; wet switch, ez trap and conden

Completed (3) Plan member AC tune ups. 3 Ton Minisplit with (2) Ceiling cassettes and (1) wall mount in garage. 6 years old 2 Ton Carrier Heat pump that serves the game room/basement only. Installed 2023 3 years old. 5 Ton Trane heat pump/propane hybrid system installed May 2016 10 years old. Filters are fiberglass “micro power guard media” (16x25x1) and (16x20x1) and washable for Minisplits. Homeowner will purchase these as needed For each system: -Inspected indoor and outdoor coils Indoor and outdoor coils in good condition. -Inspected wiring, controls, electric motors and components; left estimates for surge protectors Carrier outdoor unit and indoor unit, the Minisplit AND the Trane indoor equipment have surge protectors. Outdoor unit main system does not. Left empty estimate Measured temperature split and static pressure Inspected drains; cleared traps, tested pump; both the traditional split systems would benefit by replacing the pvc traps with traps with cleanout and ove

Completed (2) AC tune ups. 1st Floor 3.5 Tons AC dates to 2010 16 years old, furnace is 2019 7 years old 2nd Floor 3 Ton AC also dates to 2010 16 years old; furnace is 2019 7 years old Replaced 16x25x1 filter for 2nd Floor Replaced 20x25x1 for 1st floor For each system: Indoor and outdoor coils in good condition; cleaned outdoor coils with available hose Bib. 2nd floor system has some buildup on backside. But otherwise they were clean. *Units are still level from work done in 2024 Inspected wiring, controls, electric motors and components; left estimates for surge protectors. Home odors have a whole home surge protector at panel. Surge protectors for separate circuits are still recommended Up to (4) can be installed. Measured temperature split and static pressure Inspected drains; cleared EZ trap, tested pump; added treatment tabs to drain pan. Checked integrity of compressor motor (mega ohm test) Assessed refrigerant charge checked pressures. Closed bypass dampers and wa

Completed AC tune up for 4 Ton Goodman AC system Furnace is 9 years old. AC is approximately 3 years old Replaced 16x20x1 filter with one provided by homeowner Indoor and outdoor coils in good condition Inspected wiring, controls, electric motors and components; left estimates for surge protectors. The Y conductor between the thermostat and the indoor equipment control is shorted and the green conductor is therefore used for the cooling contact. There is no way of controlling the fan. The only way to address this is to install a thermostat with an EIM. A wire pull is not feasible. Wire is anchored and basement ceilimgs are drywall. *The cost of repairs for components that may be damaged by surges can far exceed the cost of surge protectors Measured temperature split and static pressure Inspected drains; cleared EZ trap, Checked integrity of compressor motor (mega ohm test) Assessed refrigerant charge checked pressures. Good AC system operating well at this time.

Completed AC tune up for 3 Ton Trane inverter heat pump system System installed August 13, 2025 Replaced 24x24x1 filter; I left a 12x12x1, homeowner will replace Indoor and outdoor coils in good condition Inspected wiring, controls, electric motors and components; Measured temperature split and static pressure Inspected drains; cleared EZ trap, added treatment tabs to drain pan. Assessed refrigerant charge checked pressures. AC system operating well at this time.

Completed heat tune up for 100,000 BTU natural gas furnace. (Furnace installed Oct. 2022; AC Installed July 2019) Replaced 16x25x1 filter; was very dirty recommend replacing once every 2-3 months provided estimate for Air ranger electrostatic filter. This filter assembly powered by 24V acts as a MERV 14 filter. Replace media every 3-4 months.

Cleared EZ trap and flushed with water. System does not have a wet switch. This switch would shut equipment down if water makes its way on floor near equipment. Provided email estim

Completed AC tune up for 5 Ton Lennox heat pump system. Equipment is propane furnace/heat pump hybrid System is 12 years old. Filter Replaced in February; in good condition Indoor coil had refrigerant oil on the top right side. Conducted electronic leak search and found leak at top of A coil. Showed homeowner video of this.
