Responded to service call for kitchen sink clogged drain causing water to back up under sink when garbage disposal activated. Diagnosed significant grease buildup in the drain system. Successfully cleared blockage using drain snake, restoring proper drainage and eliminating backup issues.
Performed scheduled bi-annual maintenance on 24-year-old Lennox high-efficiency furnace. Replaced air filter and conducted comprehensive inspection, noting some spots on heat exchanger that are not penetrating at this time. System appears operational with recent draft motor replacement from previous year.
Diagnosed system with insufficient heating and poor airflow caused by severely clogged evaporator coil. Performed thorough cleaning of evaporator coil mounted above furnace to restore proper airflow. Conducted comprehensive furnace inspection with heat exchanger integrity check, followed by successful test run confirming restored heating performance and proper system operation.
Responded to no heat complaint on 21-year-old Lennox furnace (CM: 2025). Customer had previously cleared exhaust blockage which restored system operation. Inspected control board indicator lights (2 amber, 1 green) confirming normal operation status. Observed significant ice buildup on outdoor unit and drainage pipe. No additional repairs needed as system was functioning properly at time of service.
Responded to service call for leaking exterior hose bibb causing ice formation along foundation despite closed interior valve. Diagnosed faulty hose bibb as source of the leak. Replaced defective hose bibb to eliminate water leakage and prevent further ice accumulation and potential foundation damage.
Diagnosed system showing pressure switch code on 2-year-old Lennox furnace that was cycling briefly before shutting down. Inspection revealed frozen exhaust venting on rooftop as root cause. Successfully thawed ice blockage in vent pipe, drained the venting system, and verified proper system operation through multiple test cycles.
Diagnosed Lennox furnace with intermittent heating failure due to pressure switch tripping. Determined the unit was not properly pitched, causing condensate drainage issues that blocked the pressure switch hose during extended operation. Attempted to adjust pitch but could only correct side-to-side alignment; recommended installation crew return with appropriate tools to properly pitch the furnace forward to ensure proper condensate drainage.
Responded to service call for boiler making popping noises during operation. Diagnostic inspection revealed sediment buildup in heat exchanger, likely caused by hard water and lack of system flushing maintenance. Discussed remediation options with homeowner including system flush service. Recommended complete boiler tune-up to ensure optimal performance. Homeowner will review estimate and confirm service decision.
Responded to service call for completely clogged toilet that was unresponsive to plunging attempts. After assessment, advised customer of snaking procedure required to clear blockage, but customer elected to attempt clearing the clog independently due to cost considerations.
Responded to service call for a 15-year-old Trane 80% furnace experiencing intermittent burner shutdown with 2-blink code (excessive ignition attempts). Performed comprehensive diagnostic inspection including heat exchanger, combustion system, ignition components, and filter; furnace operated normally during visit with no observable issues. Second service company to evaluate with same findings.
Responded to warranty call for laundry drain backing up. Diagnosed clog in 3" drain under concrete. Issue requires specialized equipment beyond scope; referred customer to drain cleaning company. If problem persists after professional drain cleaning, recommendation is to replace old cast iron piping.
Diagnosed 5-year-old furnace failing to produce heat due to a faulty igniter that was not functioning during startup sequence. Further inspection revealed significant deterioration of the secondary heat exchanger with multiple pinholes present, rendering the unit unsafe for continued operation. Customer was shown the damaged components and elected to seek additional quotes for furnace replacement.
Replaced non-connecting Honeywell Pro Series thermostat with new unit after troubleshooting connection issues. Successfully established internet connectivity, allowing customer to control heating system via mobile device as requested. System now functioning properly with heat cycling as intended.
Responded to no heat call for 1-year-old natural gas furnace. Diagnosed limit switch fault code; found limit switch stuck open despite cool system. Observed heat exchanger was in good condition, but discovered Merv 13 filter clogged with white residue from ultrasonic humidifier. Replaced faulty limit sensor and air filter, restoring normal operation. Advised customer about humidifier options and recommended using distilled water if continuing ultrasonic humidifier use.
Diagnosed and serviced 10+ year old Westinghouse furnace (Model M3RI 060A AW) with intermittent no-heat condition. Found completely plugged condensate drain causing water backup into collector box and inducer motor, which triggered the inducer motor limit to shut down system operation. Cleared blocked drain line to restore proper drainage. Inspection revealed advanced rust on heat exchanger, leaking collector box, and corroded burners causing inconsistent ignition across all burners. System is operational after service but showing significant age-related deterioration.
