Performed heating maintenance on two geothermal heat pump systems, inspecting air handlers, controls, and associated piping and valves, and verifying thermostat operation. Checked geothermal loop pressure per the customer's concern and restored it to the 40 psi target following the previously noted pressure loss, then confirmed both systems were operating properly in heating mode. Filters (30x32x2) were not included with this visit.

Returned to address an actively leaking section of the water supply piping at the dual whole-house filtration manifold. Inspected the soldered copper joints, ball valves, and filter housing connections, then repaired the leaking section and verified all connections were watertight. Confirmed proper operation of the filter housings and drain assembly, with no active leaks present at completion.

Responded to a callback for a reported leak at the wall in the basement following a prior whole-house water filtration installation. Inspected the GE filtration unit, including the wall-mounted bracket, copper inlet and outlet piping, press-fit and brass fittings, and the ball shutoff valve, and found no visible leaks, corrosion, or damage at the time of service. The filtration system was confirmed to be properly secured and in good working condition.

Installed a whole-home dual-stage filtration system with large sediment and carbon cartridges, plumbed with copper piping and isolation shutoff valves. Replaced the hot water recirculation pump, repaired the shower cartridge, and flushed the water heater to remove accumulated sediment, with all connections inspected and no visible leaks.

Performed a plumbing estimate for a water heater flush and sediment filtration after the customer reported a green, slushy slime-like substance discharging from fixtures and filters. Inspected the water softener installation, copper supply lines, and shower fixtures, finding no visible leaks, corrosion, or damage, and reviewed sediment filter options to address the contamination and protect downstream equipment.

Performed an on-site evaluation of the existing heating system and determined it is back drafting and unsafe to operate. Documented the aged upright furnace unit with its exposed internal components and worn insulation, along with the galvanized plenum and ductwork connections, and noted the extensive animal damage to the ductwork. Assessed options for a basic, cost-effective replacement furnace to restore heat, and documented the exterior mini-split condenser, which is heavily obstructed by overgrown vegetation.

Accessed the crawlspace to investigate a reported constant drip beneath the structure and inspected the water supply piping, including the PEX-to-CPVC transition fittings. Identified mineral buildup and corrosion at a connection joint as the likely source of the leak and evaluated the surrounding piping, couplings, and valves for additional signs of failure.

Serviced a vintage upright furnace in a utility closet and documented the unit's condition, including the open lower access door exposing the burner assembly and wiring, the galvanized flue/duct with foil tape repair, and surface corrosion on the adjacent metal housing. Evaluated the stand-alone propane heater, which requires connection to the propane supply tank, and noted the flexible gas line/hose and fittings staged for the hookup.

Responded to a no-heat call on a 15-year-old gas-fired hot water baseboard heating system with a suspected failed igniter. Accessed the boiler, inspected the ignition components, controls, and wiring, and evaluated the circulator, expansion tank, and flue venting for proper operation. Noted heavy dust and debris buildup on the unit and surrounding components.

Cleared a clogged double-basin kitchen sink drain, removing the blockage from the drain line and restoring proper flow through both basins. Inspected the strainer baskets and the adjacent dishwasher connection, and verified unobstructed drainage with no leaks at the completion of the service.

Performed heating maintenance on an aging upright furnace with a reported intermittent ignition issue (unit would not stay lit). Cleaned the burner assembly, pilot/ignition components, and interior cabinet to remove accumulated dust and debris, then verified stable flame and proper combustion. Confirmed the thermostat was calling for heat in Heat mode and that the system cycled correctly through a full heating sequence.

# HVAC Maintenance - Heating System Service Completed basic monthly heating maintenance visit on Trane air handler unit. Performed standard heating system diagnostics including electrical measurements using digital multimeter, which indicated 2.5 CA reading during operational testing. Inspected air handler cabinet, control panel, refrigerant lines, and condensate drain for proper operation and signs of wear. Unit showed normal age-related dust accumulation but maintained functional integrity. Unable to replace air filter as filter size was not identified during this visit.

Responded to water leak under kitchen sink. Upon arrival, found disconnected drain pipe beneath sink causing active water leak. Inspected under-sink plumbing assembly including garbage disposal unit, P-trap, and drainage connections. Reconnected and secured loose drain pipe, verified all PVC connections were properly sealed and tightened. Tested system by running water through sink and disposal to confirm leak was resolved and all connections remained secure under flow. Also inspected toilet tank mechanism during visit and documented condition of flush valve assembly. System restored to proper working order with no active leaks detected upon completion.

Returned to site with replacement control board, transformers, and circuit breakers to complete HVAC system repair. Installed new electrical components in the unit's control panel, terminated all wiring connections to breakers and control board per manufacturer specifications, and restored power to the system. Verified proper operation of all electrical circuits and confirmed unit functionality upon completion.

Performed annual maintenance on aging residential forced-air furnace system experiencing clanging noises during startup. Completed thorough blowout and cleaning of unit to remove accumulated dust and debris from burner assembly, heat exchanger, and blower compartment. Verified proper operation of Honeywell ProSeries thermostat set to 73 degrees and confirmed system cycling without abnormal sounds following service.

Conducted comprehensive assessment of crawl space plumbing system with multiple water line failures resulting in standing water accumulation. Documented existing conditions including compromised vapor barrier, exposed PVC supply lines with visible markings indicating previous repair attempts, and saturated subfloor areas requiring immediate attention to prevent structural damage and mold growth.

Responded to service call for geothermal heat pump system displaying flashing high pressure fault light upon first heating cycle activation. System defaulted to stage 2 auxiliary heat element instead of operating in geothermal mode. Inspected thermostat settings and confirmed proper temperature display and control functionality. Evaluated system pressure readings using diagnostic gauge to assess refrigerant circuit operation and identify cause of high pressure fault condition.

Completed annual cooling maintenance visit on Lennox air handler system. Performed standard inspection of blower assembly, noting significant rust and corrosion on central motor shaft requiring future monitoring. Observed aged ductwork with surface discoloration but functionally intact. Replaced 14x24x1 air filter as included in service. Verified blower wheel operation and airflow through metallic supply ductwork. System operational at time of departure, though motor shaft corrosion should be addressed during next service interval to prevent potential bearing failure.

Completed site measurements for water softener reloop installation. Documented existing plumbing configuration including water treatment system with pressure gauge, brass fittings, PVC piping, and filter housing mounted on basement wall. Captured detailed photos of current setup to facilitate accurate planning and material ordering for the reloop modification.

Responded to clogged drain service call and successfully cleared blockage from exterior drain line. Removed and cleaned pipe fitting, extracted accumulated debris and sediment from the line, and verified proper water flow upon completion. All components were reassembled and system tested to ensure full functionality.
