Diagnosed Lennox Merit Series furnace with no heat complaint. Verified 24V to gas valve but no gas flow. Visual inspection revealed burn damage on control board at gas valve output connection. Heat exchanger was inspected and cleared. Advised customer that control board replacement is required to restore heating function.
Responded to a no heat service callback where previous service could not identify the issue. Diagnosed furnace failure due to pressure switch activation caused by an obstruction in the exhaust system. Removed rocks from the intake pipe, verified proper pressure readings, and reinstalled exterior components. Unit now operating normally and providing adequate heat to the residence.
Conducted comprehensive furnace tune-up including inspection of burners, gas pressure, flame sensor, and blower wheel motor with no immediate concerns identified. Replaced air filter, cleaned pressure switch, and verified thermostat operation. System is functioning properly with normal air handler operation and heating performance.
Responded to no-heat call for relatively new furnace (< 6 months) exhibiting multiple error codes (E223, E225, E227, E229). Diagnostic testing revealed malfunctioning pressure switches and compromised venting system. Attempted to resolve by forcing system into low-fire mode, but issues persisted. Recommended follow-up service to properly evaluate and correct the venting installation to restore proper operation.
Performed a furnace tune-up on residential system. During heat exchanger inspection, discovered a significant 2-3 inch crack in one combustion chamber. Detected rising carbon monoxide levels with increased temperature operation. Informed customer that heat exchanger replacement or full furnace replacement is required.
Performed annual generator maintenance service including battery check, air filter replacement, spark plug replacement, oil filter change, and complete oil change. Reset maintenance light and verified proper operation after service. Generator is now fully serviced and operational for the coming year.
Performed inspection of reported bathroom leak affecting ceiling below. Accessed plumbing through cabinet access panel to evaluate shower valve system. Observed aged copper supply lines with visible oxidation and standard PVC drain assembly. Provided comprehensive estimate for shower valve replacement to address recurring leak issue that was previously repaired approximately three years ago.
Completed sold repair by replacing defective condensate pump which had failed to operate properly, and performed comprehensive furnace tune-up including inspection of heat exchanger, venting, exhaust flue, and all safety components. System is now functioning normally with proper operation verified through testing on both high and low settings.
Completed routine maintenance on a 15-year-old Goodman natural gas furnace. Verified system is burning safely with good electrical components and connections. Cleaned flame sensor and noted rusting on ignitor which could cause future issues, though currently operational. All amp draws within normal range and condensation drains clear.
Responded to service call for non-operational boiler serving in-floor heating system. Diagnosed issue with year-old unit that was installed by another contractor. Determined boiler was left in standby mode rather than operation mode. Adjusted controller settings to proper operation mode, which resolved the issue completely. System now functioning correctly with all components operating as designed. Installation workmanship appears satisfactory.
Diagnosed non-functioning furnace with condensate pump failure which caused water to back up into the system, resulting in water damage to the inducer and electrical wiring. Performed emergency service by draining the inducer assembly and identified issues with the electrical outlet powering the condensate pump. Scheduled follow-up with electrician and prepared quote for replacement condensate pump and inducer components.
Responded to customer complaint of loud banging noise from vents during furnace operation in a recently installed system. Removed vent diffusers and adjusted accessible ductwork. Cycled system multiple times with no recurrence of noise. Verified thermostat functioning properly at 69°F setpoint with system responding appropriately.
Responded to a service call for a 10-year-old R22 air conditioning system. Diagnosed a refrigerant line set puncture caused by customer's renovation activities (nail penetration). Photographic documentation obtained showing the damage to the wall and line set. Presented repair options and coordinated with service advisor for follow-up system replacement consultation.
Responded to no heat call for 22-year-old Bryant +90 furnace (installed 2003). Diagnostic inspection revealed burnt control board with transformer or relay damage causing complete system shutdown. No evidence of rodent/insect intrusion found. Further electrical components inspection conducted and documented with photos. Furnace requires control board replacement to restore functionality and allow for complete system diagnosis of any secondary damage.
Replaced leaking irrigation valve connected to Well-Xtrol expansion tank system. Inspected copper piping configuration and verified proper function after installation of new valve assembly.
