Diagnosed and resolved no heat issue on 6-year-old Goodman furnace by identifying faulty low fire pressure switch that was not operating within rated specifications. Verified proper draft and absence of flue blockages, confirmed pressure switch tubing and fittings were intact. Replaced pressure switch assembly and conducted multiple operational tests to ensure reliable system performance. Combustion analysis confirmed proper operation after repair.
Diagnosed issue with 5-year-old two-zone HVAC system where basement zone damper was failing to close when temperature set point was reached. Replaced defective zone motor and damper, ensuring proper alignment during installation to prevent recurrence of the issue. System now functioning properly with ZoneFirst control modules correctly managing both zones.
Performed tune-up inspection on 20-year-old furnace. Discovered significant deterioration including corrosion in inducer and collector box with active leakage. Visual inspection confirmed crack in heat exchanger, documented with photographic evidence. Due to critical safety concerns and extensive deterioration, recommended full furnace replacement.
Performed comprehensive furnace tune-up on 30-year-old RPI II system with intermittent operation issues. Adjusted gas train pressure from 3.94 inWC to 3.34 inWC and cleared accumulated debris from condensate drain line and trap. Verified proper function of inducer motor, capacitor, pressure switch, control board connections, and thermostat operation with combustion CO recorded at 2 ppm. Noted moderate condition of return air filter; system now operating normally.
Performed comprehensive furnace tune-up on 5-year-old natural gas system. Addressed operational issues by cleaning dirty flame sensor, removing spiderweb buildup, clearing unwanted water accumulation from inducer housing, and bypassing control board to restore heating function. Completed system cleaning and replaced air filter to ensure optimal performance.
Performed comprehensive furnace tune-up including verification of pressure switch operation and carbon monoxide testing for safe combustion. Conducted electrical component diagnostics (flame igniter, gas valve solenoid resistance, flame sensor microamp measurement, blower motor capacitor condition) and gas pressure verification/adjustment for proper system operation. All components were reconnected, electrical connections secured, and system operation confirmed with the furnace now functioning properly.
Performed warranty service visit on recently installed Lennox HVAC system to address multiple installation deficiencies. Corrected issues with unsealed fresh air intake tube, uncaulked PVC fresh air tubing, and improperly installed cold air exchange ducting. Noted that according to customer, the new supply installation did not follow agreed plan; submitted install correction form for follow-up work.
Responded to a service call for leaking faucets in master bathroom, upstairs showers, and basement sink. Diagnosed issues including a faulty cartridge and loose connections in the MOEN fixtures. Replaced the damaged cartridge and tightened all supply lines and handles, successfully resolving the leaks.
Installed a 1" ball valve with coupling for an irrigation line to replace a failing water valve. The new valve will effectively control water flow through the line and provide a reliable solution for the customer's system.
Responded to low water pressure issue in kitchen. Upon inspection, identified outdated water heater, broken main service valves, and outdated pressure reducing valve (PRV) as contributing factors. Assessed upstairs bathroom components including toilet, shower valve, faucet, angle stops and supply lines, all requiring replacement. Provided multiple estimates for necessary repairs and ADA compliant toilet installation.
Responded to no-heat call for ICP 80% furnace (28 years old). Upon inspection, identified multiple cracks in both burners and the heat exchanger. Due to significant safety concerns, performed a safety shutdown of the system. Visually demonstrated the damage to customer's daughter and explained the critical hazards. Recommended consultation with comfort advisor regarding replacement options due to equipment age and safety issues.
Cleared clogged kitchen sink where water was backing up into disposal side when using the opposite basin. Inspection of under-sink plumbing revealed improper drain line pitch. Raised and adjusted the drain line configuration to improve flow and eliminate backup issues.
Performed complete furnace tune-up and safety check on 12-year-old Lennox unit. Conducted comprehensive inspection including gas leak detection, pressure switch verification, carbon monoxide testing, flame igniter testing, and gas pressure adjustments for both heating stages. All systems verified operating correctly with no issues found.
Performed annual inspection on two commercial furnace units. Diagnostic testing with multimeter confirmed proper electrical functionality of control module and gas valve. Noted accumulated dirt on internal components and filter. Replaced dirty air filter on one unit to restore proper airflow. Visual inspection of all wiring connections, valve assembly, and mounting components showed no issues requiring further service.
Performed scheduled maintenance on two natural gas furnaces over 10 years old. Inspected blower wheel assemblies and removed accumulated debris to ensure proper airflow. Both systems are operating correctly with all components in satisfactory condition.
