Verified thermostat function and system controls as part of the heating tune-up. The system was left in proper working order; the 16x25x4 media filter was not included in this visit.

Installed a complete Lennox heat pump system, including the vertical air handler in the utility closet with new refrigerant lines, condensate drain piping, and supply ductwork connections. Evacuated the refrigerant circuit to 151 microns with zero rise per minute, confirming a dry, leak-free system prior to refrigerant release and commissioning.

Performed seasonal heating maintenance on the system, including installation of a new 16x25x4 filter, and verified proper operation of the Lennox thermostat in heat mode. Confirmed the thermostat was calling for heat with the setpoint properly maintained, and the system was left operating normally.

Performed an on-site assessment for a ductless mini split installation in a 500 sq ft cabin with vaulted knotty pine ceilings. Evaluated the kitchen's upper wall above the cabinetry as the proposed indoor air handler location, accounting for the open vaulted layout and nearby electrical service. Documented site conditions with photos to support equipment sizing, line set routing, and electrical requirements for the installation proposal.

Performed scheduled heating maintenance on two systems (CCHP heat pump and CCH), including replacement of 20x20x1 air filters. Verified heat pump operation via thermostat diagnostics, recording 9,041 compressor runtime hours, outdoor fan speed of 374 RPM, 73.4°F outdoor air temperature, and 109.8°F outdoor coil temperature with compressor reduction mode off. Confirmed heating performance with a supply register temperature reading of 69.2°F.

Performed annual preventive maintenance tune-up on a 12-year-old geothermal heat pump, including inspection of the control compartment's electrical components (capacitor, relays, terminal block, and wiring) and verification of proper system operation. The unit was found to be operating normally with no reported issues or deficiencies, and the associated air handler and UV light components were noted in place.

Inspected the shower for a dripping fixture and evaluated the valve assembly, accessing it from the valve trim inside the shower since no rear access panel is present. Identified the handheld showerhead, shower arm, and wall flange with visible mineral buildup and surface spotting, and noted staining on the upper wall and ceiling edge for monitoring of possible moisture intrusion. Diagnosed the hot-side leak and valve condition for repair or replacement of the shower valve components.

Performed a routine clean and check on the heating system, including inspection of the system components and verification of the White Rodgers digital thermostat, which was intact and operating properly. Inspected the return air filter, noting an installed 16x20x1 filter that differs from the 20x25x4 size specified for this system, and recommended installing the correct size to maintain proper airflow and efficiency.

Performed a pre-season tune-up on a two-year-old Lennox furnace, including inspection and cleaning of the blower assembly to remove accumulated dust and debris from the squirrel-cage wheel blades. Verified thermostat operation and calls for heat, and checked the system for proper startup and operation ahead of the heating season; no issues were found.

Performed seasonal heating maintenance on the gas furnace and air handler, including replacement of the 20x20x1 return air filter and inspection of the blower assembly, burners, and heat exchanger. Verified proper operation of the whole-house humidifier, condensate drain piping, and refrigerant line insulation, and confirmed the system completed a normal heating cycle with no leaks, corrosion, or visible damage observed.

Performed annual heating system maintenance, inspecting the supply ductwork, damper assembly, linkage hardware, and control components for proper operation and airflow. Removed and inspected the metal mesh air filter, which showed heavy dust and debris loading, and documented the condition for filter cleaning or replacement to restore proper airflow. Verified all components were free of frost, ice, and corrosion, and completed the maintenance log entries.

Replaced the failed thermostatic expansion valve (TXV) on the system, brazing in the new valve and reconnecting the refrigerant lines. Inspected the surrounding copper piping and found deteriorated, torn suction line insulation and oxidized solder joints, noting the need for proper re-insulation and monitoring. Verified ambient and system temperatures with a digital thermometer to confirm proper operation after the repair.

Performed monthly preventive maintenance inspection on a gas-fired Daikin furnace, removing the lower access panel to inspect the gas valve, blower motor, wiring harness, and Honeywell control module, and verifying operation with a digital meter. Checked gas piping, flexible connectors, shutoff valves, PVC condensate/vent piping, and ductwork connections for leaks or damage, with no frost, rust, or deficiencies noted. Visually inspected the adjacent A.O. Smith commercial water heater, including flue, gas connections, and piping, with no visible damage or issues; air filter replacement was not included in this visit.

Responded to a no-cooling call on three rooftop package units, with one unit repeatedly blowing control circuit fuses. Inspected the Puron-charged unit with the panels removed, evaluated the condenser section and electrical components, and replaced the blown Low-Peak LP-CC-30 time-delay Class CC fuse. Verified the unit's electrical circuit and operation after the repair to restore cooling.

Performed scheduled monthly heating maintenance on the Lennox ML196UHE Merit Series gas furnace, including replacement of the 16x25x1 air filter and inspection of the unit's operating condition and service history documentation. Observed no frost, ice, or major damage at the furnace; noted heavy rust and corrosion at the base of the adjacent water heater tank, recommending that it be monitored or evaluated for replacement.

Performed diagnostic and tune-up on a 9-year-old split-system AC paired with a Tempstar gas furnace and air handler that stopped cooling two weeks prior. Inspected the air handler, plenum, ductwork, refrigerant lines, and condensate drain, and verified thermostat operation, which showed a call for cooling (Cool On, setpoint 72°F) with indoor temperature holding at 80°F, confirming the system is not meeting setpoint.

Performed seasonal heating system maintenance, verifying Lennox digital thermostat operation and setpoints. Inspected air handler cabinet and evaporator coil, noting dust and debris accumulation on the coil fins that should be monitored and cleaned as needed. Filter (20x20x4) was not included in this visit and should be checked and replaced at the next scheduled interval.
