Responded to no heat complaint on 20-year-old mobile home furnace. Diagnostic testing revealed failed control board and transformer requiring replacement. Visual inspection identified significant dust accumulation on blower motor and potential crack in heat exchanger. Due to age of unit and critical safety components compromised, recommended complete furnace replacement rather than component repair.
Diagnosed and replaced faulty inducer motor on 7-year-old furnace that was producing whining noises and causing system to cycle on and off intermittently. Unit is now operating properly with normal heating function restored.
Performed furnace tune-up for new customer with aging system. Diagnosed faulty thermostat requiring manual tapping to operate. Replaced thermostat and verified proper system operation with voltage testing.
Responded to no-heat call for boiler displaying F005 error code. Performed comprehensive diagnostic service including vent inspection, condensate trap cleaning, and ignitor maintenance. Reset system and confirmed proper heating operation with all components functioning normally.
Diagnosed leaking water heater tank requiring full replacement. Identified non-functioning water softener during water testing. Customer approved installation of new 80-gallon electric water heater with mixing valve and replacement water softener; scheduled installation for Monday.
Performed diagnostic assessment on non-functional 1.5-year-old Lennox mini-split system and determined the system is completely depleted of refrigerant charge, explaining the no heat/cool complaint. Visual inspection of both indoor wall-mounted unit and outdoor condenser revealed no obvious external damage, but system requires leak detection and subsequent refrigerant system repairs to restore operation. Discussed findings with homeowners and recommended follow-up with service advisor to review repair options.
Performed diagnostic evaluation on 15-year-old Lennox furnace as a second opinion after another company tagged unit for compromised heat exchanger. Visual inspection revealed rust on primary heat exchanger eyelets suggesting exhaust leakage, and potential pinholes in secondary heat exchanger. Though unit remains operational, advised customer of risks associated with continued operation. Performed resistance testing and thorough component inspection with no additional issues found. Will follow up with heat exchanger replacement options and Lennox warranty verification.
Diagnosed low water pressure issue in infloor heating boiler system. Increased pressure to 15psi, purged air from loops and pump, and verified pump operation. Set water temperature to 135°F and cycled system to confirm restoration of normal operation for the infloor heating.
Performed scheduled 5-year tune-up on Lennox residential HVAC system. Inspected furnace and air handler components, conducted electrical diagnostics using multimeter (reading 56.5V), and verified proper airflow direction. Noted filter was in marginal condition and replaced it to ensure optimal system performance.
Diagnosed no heat issue on aging boiler system with four zone valves. Found thermostats calling for heat with zone valves opening but failing to activate end switches due to faulty wiring connections. Corrected the issue by rewiring all zone valves, verified proper operation of each zone valve and confirmed all zones successfully activate the boiler. System now functioning normally. Recommended backflow preventer installation.
Responded to no-heat call for aging system (10+ years). Diagnosed multiple issues: failed igniter, noisy inducer motor, and non-functional gas valve. Replaced defective gas valve, restoring proper heating function to the system.
Diagnosed and replaced leaking 1" irrigation ball valve at exterior water supply line. Removed old valve assembly and installed new shut-off valve for the irrigation system. Confirmed proper operation with no leaks after installation.
Responded to service call for HVAC system after power outage. Diagnosed multiple communication errors on zoning system indicated by thermostat alerts including "Lost Communication With Device" and "Zone 2 Temp Sensor Fault." Verified electrical connections at control board, confirmed proper power restoration to system components, checked damper functionality, and validated thermostat settings. System now heating properly with all electrical connections secure.
Diagnosed and provided estimate for toilet flange repair using a 4x3 inside fit flange to replace corroded existing flange. Customer purchased HOROW one-piece toilet; proposed complete toilet installation after cutting out damaged flange section.
Replaced leaking 2017 A.O. Smith electric water heater that showed significant tank corrosion and floor staining at base. Customer accepted replacement estimate after inspection confirmed tank failure. Also inspected toilet with intermittent leak history, which had previously resolved itself.
