Performed standard furnace tune-up on residential FRP unit of unknown age. System inspection revealed normal operation with no immediate concerns. Conducted comprehensive maintenance including combustion analysis, gas pressure verification, inspection of heat exchanger, flame sensor, burners, and blower components. Confirmed proper thermostat operation and heating performance. Air filter in good condition; cleaned pressure switch. Documented system with photos showing ductwork configuration and motor assembly.
Responded to no heat complaint at rental property with 18-year-old Coleman furnace. Diagnosed multiple issues including burner ignition failure, condensate drainage problems, and potential heat exchanger concerns based on erratic combustion analysis readings. Performed temporary repairs by clearing orifices, adjusting gas valve, disassembling draft motor assembly to clear condensate trap, and ensuring pressure switches/vacuum hoses were unobstructed to restore heat temporarily until permanent solution can be implemented.
Responded to no heat call for 18-year-old Lennox furnace. Diagnosed stuck high limit switch, temporarily restored operation by manually re-engaging switch through tapping method. Identified root cause as furnace overheating likely due to restrictive filtration. Inspection revealed significant rust and potential heat exchanger breach where primary connects to secondary. Customer opted for temporary repair and scheduled consultation for furnace replacement.
Responded to no-heat call for 20+ year old Buderus boiler with pilot light failure. Diagnosed broken pilot tube causing improper gas distribution and identified significant soot accumulation on burners and pilot assembly. Attempted to source replacement standing pilot assembly but manufacturer only offers intermittent pilot version. Universal assembly installation was unsuccessful due to incompatible pilot tube fittings. Homeowners opted for service advisor consultation.
Responded to service call for radiator system issues. Inspected and found a severely corroded pipe elbow at radiator connection with active leak and significant water damage to surrounding wooden flooring. Replaced deteriorated radiator valve and repiped connection point, followed by bleeding all four radiators in the system to restore proper operation.
Diagnosed and resolved two bathroom sink issues: removed water bottle cap causing clog in main floor sink drain assembly, and replaced damaged components on second floor sink by installing new PVC sanitary tee, p-trap, and drain piping. Addressed leak-related ceiling damage likely caused by improper winterization of the home. Both sinks tested and confirmed fully operational after repairs.
Performed tune-up service on 14-year-old furnace. System operational but required maintenance including filter replacement due to dirt accumulation. Identified and documented stripped gas valve. Electrical testing showed readings within normal range at 25.7V. Recommended monthly filter changes to client.
Responded to emergency call for basement flooding caused by failed condensate pump. Replaced defective pump with new unit from inventory. Identified broken humidifier damper as secondary issue which was causing continuous humidifier operation and contributing to excessive water accumulation in basement.
Diagnosed 15-year-old Slant Fin boiler with no heat issue. Determined gas valve failure - pilot light functioning properly but main burners not igniting despite verified 25V power supply to both ignition module and valve. Currently sourcing replacement part for repair completion.
Diagnosed Luxaire furnace (22 years old) exhibiting no heat condition with board flashing error code for open high limit switch. Successfully restored function by resetting stuck limit switch, but noted it will likely fail again soon. Inspection revealed severely degraded igniter that remains operational for now. Verified heat exchanger integrity with no cracks or damage found. Recommended replacement of high limit switch and igniter to prevent future no-heat conditions. All other components tested and functioning properly.
Performed diagnostic assessment of radiator heating system following customer report of partial heating in upstairs radiators. Conducted thorough inspection of boiler components, control board, and associated plumbing connections. Completed full system flush, bleeding of radiators, and introduction of Fernox treatment to improve circulation and efficiency. Refilled system to proper pressure and verified proper operation of all heating zones.
Successfully completed a 5-hour boiler maintenance service involving the replacement of a malfunctioning pressure gauge and installation of a new expansion tank with shut-off valve. After draining down the multi-level system, refilled the boiler, performed comprehensive air bleeding, and verified proper system cycling and operation to ensure optimal heating performance.
Cleared clogged toilet caused by significant calcium buildup resulting in semi-hard blockage. Successfully restored proper drainage using auger. Advised customer on toilet replacement options due to mineral accumulation affecting performance.
Diagnosed furnace failing to reach thermostat setpoint due to high pressure switch fault preventing second stage operation. Discovered buildup issues affecting collector box, inducer assembly, and secondary heat exchanger. Recommended replacement of affected components and provided customer with estimate for repairs.
Responded to emergency no-heat call for 10+ year old natural gas furnace previously shut down by gas company due to dangerous carbon monoxide readings. Diagnostic testing with Testo analyzer confirmed critical CO levels exceeding 6300 ppm (14,000 ppm air-free), indicating severe heat exchanger failure. Inspection revealed significant secondary heat exchanger clogging, rendering the unit unsafe for operation. Recommended and scheduled complete system replacement due to age of equipment and non-repairable safety hazard.
