Responded to customer with non-operational Bradford White 72-gallon natural gas water heater. Upon inspection, found unit was leaking and failed to ignite, requiring immediate shutdown with power disconnected and water supply to home turned off. Customer informed of replacement options and HVAC service advisor requested for quote on tankless combi boiler replacement.
Responded to no-heat call for 28-year-old furnace that was blowing cold air and not igniting. Diagnostic testing confirmed failed hot surface igniter (HSI). Replaced defective HSI component and verified proper system operation with combustion analysis using Testo 310 analyzer.
Responded to no heat call for furnace operating 12° below setpoint. Diagnostic testing revealed failed inducer motor with visible corrosion and rust formation on internal components. Successfully replaced inducer motor assembly, restoring proper system operation and heat production.
Responded to service call for one-year-old Carrier heat pump system with ecobee thermostat displaying "action required" notification. Diagnosed issue with auxiliary heat running unnecessarily due to improper temperature threshold configuration. Adjusted outdoor temperature setpoint from 70°F to 40°F to enable proper heat pump operation above 40°F, eliminating reliance on auxiliary heat during moderate temperatures. System now functioning correctly with appropriate staging sequence.
Responded to a no-heat service call for a Lennox unit displaying error code 475. Upon inspection, determined the inducer motor was failing, preventing proper furnace ignition. Replaced inducer motor assembly to restore normal heating function. Previous repair attempts by another company were unsuccessful despite multiple part replacements.
Responded to heat pump malfunction complaint where system was incorrectly operating on auxiliary heat. Diagnosed issue as a closed damper preventing airflow to main level, causing heat pump to only service the upper level. System was functioning within normal parameters but not meeting occupant expectations due to improper damper position. Adjusted damper to "open" position, disabled energy-saving features on Ecobee thermostat to reduce callbacks, and educated homeowner on proper system operation and damper functionality.
Inspected outdoor spigot system and identified non-frost free fixture with a corroded copper supply line and leaking gate valve. Shut off water supply to the spigot and performed diagnostic assessment of the installation. Provided customer with recommendations for replacement of outdated gate valve and installation of frost-free spigot to prevent future freeze damage.
Responded to no-heat issue with 6-month-old Lennox furnace displaying low fire pressure switch codes during call for heat. Diagnostic testing revealed improper venting termination outside was causing moisture accumulation and exhaust turbulence. Modified and reinstalled vent termination to correct airflow, allowing furnace to successfully complete full cycles through both low and high fire operation. System inspection confirmed no additional issues present; repair completed under warranty.
Responded to customer complaint of blower running constantly in an older HVAC system. Diagnosed the issue as a loose wire connection and repaired it. Conducted system verification by cycling through heating and cooling modes with the thermostat, confirming the system now operates properly with fan responding correctly to auto setting.
Responded to service call for no water to home. Diagnosed broken washer valve causing leak. Replaced both hot and cold shut-off valves with new brass fixtures to restore proper water flow to residence.
Performed comprehensive natural gas furnace maintenance including system evaluation, heat exchanger inspection, component testing (blower, inducer, safety mechanisms, flame sensor, igniter), and gas pressure verification. Conducted thorough inspection of venting system and exhaust flue. Tested system operation at multiple capacities, confirming proper functionality with readings verified using Fluke 902FC meter. System currently operating normally.
