Performed comprehensive tune-up on natural gas furnace that was experiencing reduced cycling frequency. Diagnostic testing with Fieldpiece manometer showed pressure readings of 348/358, confirming issues with pressure switch and inducer. Cleaned dirty ports and serviced pressure switch components to restore proper operation. Electrical systems verified functional with multimeter testing.
Responded to a no heat service call for high voltage baseboard heating system that was operating erratically and continuing to produce heat even when thermostat was turned off. Diagnostic testing of wiring, breaker, and thermostat control identified a faulty thermostat that was not properly cutting voltage when turned off. Replaced the manual Honeywell Home thermostat and verified proper system operation after installation.
Successfully installed customer-supplied toilet according to estimate. Removed old unit, properly secured new toilet to floor flange, and confirmed proper water connection and function. New installation is properly sealed and operating as expected.
Performed standard furnace tune-up service and inspection on unit with Nest thermostat and Aprilaire humidifier control system. Identified rust formation in heat exchanger which is functional but approaching end of life. Recommended customer begin researching replacement options for future planning.
Responded to service call for Delta faucet with no hot water flow. Diagnosed issue with flow valve/cartridge that needed replacement. Customer had already disassembled the faucet. Installed new cartridge and reassembled bathroom vanity faucet, restoring proper hot water functionality.
Responded to customer concern regarding heat pump operation during cold temperatures. Verified system functioning properly with ambient lockout correctly engaging gas heat when temperatures drop below setpoint. Explained thermostat symbols and operation modes to customer and adjusted balance points from standard 35-55°F to customer-preferred 38-55°F per request. No system malfunctions found.
Responded to service call for leaking kitchen faucet. Upon inspection, discovered faulty shutoff valves. Installed customer-supplied kitchen faucet with new shutoff valves, connecting the supply lines properly to resolve the leak issue.
Responded to service call for an 18-year-old Carrier furnace experiencing intermittent operation with error codes 12, 13, and 33. Diagnostic inspection revealed draft inducer motor with failing bearings causing squealing and scraping noises, oil leakage from blower motor, out-of-spec blower capacitor, and high limit switch activation despite low temperature readings (approximately 120°F). Heat exchanger inspection showed no cracks but significant temperature stress and rust formation. Reviewed replacement options with homeowner due to multiple component failures and age of system.
Performed furnace inspection on newly purchased home. Identified and replaced failing flame sensor, ignitor, and inducer motor while conducting electrical measurements and system diagnostics on the blower assembly and control board components.
Identified recurring freeze-related split in thin copper water supply line located dangerously close to exterior wall. Replaced damaged copper piping with PEX tubing, rerouting kitchen, laundry, and outdoor faucet supply lines to maintain appropriate distance from exterior wall to prevent future freezing issues.
Responded to callback for Lennox heat pump system where customer reported concerns about fan operation. Verified proper system function with 975 CFM airflow during heating mode and confirmed temperature rise of approximately 1° per half hour, which is within design parameters. Educated customer on normal operation of their new heat pump system and recommended adjusting bedroom register diffuser direction for optimal heating performance.
Resolved excessive noise coming from 5-year-old Carrier furnace blower wheel by addressing high static pressure in the ductwork. Removed blower assembly, modified ductwork to eliminate noise, and recommended installation of less restrictive air filter to improve system efficiency and prevent recurrence.
Conducted comprehensive inspection of 17-year-old Carrier furnace to assess safety and reliability. Major components (igniter, flame sensor, blower wheel/motor, draft motor) tested functional, however multiple holes were identified in the heat exchanger rendering the unit unsafe to operate. Combustion analysis results were acceptable, but heat exchanger deterioration appears age-related. Discussed replacement options with homeowner, including heat exchanger replacement versus full system replacement. Documentation provided for customer decision-making.
Performed scheduled maintenance on two Carrier furnaces (22 years old, model CM: 2025) per agreement. Completed thorough tune-up on both units, inspecting ductwork connections and verifying proper system operation. Equipment is aging but remains in good working condition; recommended continuing regular maintenance schedule.
Diagnosed issue with 20+ year old Slant Fin boiler experiencing continuous operation. Located short in thermostat wire between aquastat relay and main floor thermostat, confirmed through continuity testing. Temporary solution implemented allowing customer to control system via breaker until return visit scheduled for replacement of 2-wire thermostat cable.
