Responded to dispatch for continuously running toilet on ground floor unit. Upon inspection, removed tank cover and found fill valve assembly requiring adjustment. Adjusted standpipe height to correct water level. Tank interior showed extensive rust staining, mineral deposits, and mold growth indicating long-term water exposure and lack of maintenance. Fill valve with red cap and float mechanism were functional but corroded. Black rubber flapper and chain assembly showed signs of deterioration. After adjustment, toilet continued running, indicating additional repair needs beyond initial standpipe adjustment. Tank cover could not be properly reinstalled due to component interference. Documented tank condition showing heavy rust on porcelain surfaces, corroded brass fittings, discolored water, and significant biological growth along tank rim requiring comprehensive cleaning and potential component replacement for complete repair.

Responded to heating system service call and found the ventilation panel had detached from the oil heating unit and was lying on the floor. Inspected the heat exchanger assembly, which showed significant mineral deposits, scale buildup, and corrosion throughout the component and surrounding frame, indicating extended service life and moisture exposure. Documented the condition of the system with photographs showing the deteriorated ventilation panel with accumulated dust and debris, as well as the heavily scaled burner assembly with corrosion around circular openings and ductwork connections.

Completed installation of Daikin Aurora ductless heat pump system for sunroom application. Mounted indoor air handler unit on interior wall, installed outdoor disconnect box with proper electrical connections, and commissioned system for operation.

Completed comprehensive tune-up and maintenance on Lennox propane gas furnace system installed in June 2021. Performed standard inspection of burner assembly, heat exchanger, blower components, and venting system; verified proper operation and combustion efficiency. Addressed ongoing heat pump outdoor sensor issue causing frequent low battery alerts on thermostat, with battery replacement lasting only 10 days between changes; inspected sensor wiring, connections, and thermostat communication for potential power drain or faulty component requiring further diagnosis.

Conducted CPM plumbing inspection and identified a leaking temperature and pressure relief valve on gas water heater requiring replacement. Also observed possible mold/mildew development in shower area and noted properly installed expansion tank connected to water heater system.

Performed diagnostic inspection on an older Arcoaire mini-split heat pump system in sun room that was continuously running to maintain temperature. Inspection of outdoor unit revealed compressor and condenser components showing signs of wear and minor corrosion. Cleaned system components, checked refrigerant levels, and adjusted cycling parameters to improve efficiency and prevent constant operation.

Responded to a no-heat call for a new customer with an aging oil boiler (14+ years). Diagnosed issue with system startup failure after customer's nightly shutdown practice. Inspected connections and operational components in the basement utility area, noting the boiler was shutting down due to overheating caused by improper cycling. Restored heat by adjusting control settings and advised customer against turning system off completely at night, recommending thermostat setback instead for proper operation and system longevity.

Responded to service call for a sewer line backup causing water to back up into basement when fixtures were in use. Investigated approximately 20-foot straight line between house and pit, which had been emptied approximately two weeks prior. Successfully cleared blockage and restored proper drainage function.

Performed routine maintenance on a 10-year-old gas heating system. Inspected burner assembly showing proper blue flame pattern and verified gas connections for safety. Confirmed Honeywell thermostat operation with system maintaining 74° setpoint in heat mode.
