Heating, Cooling, and Plumbing Services in Chesterfield, MO

Responded to a no-heat complaint on a basement-installed furnace that cycled through heat sequence and displayed fault codes E223 and E229 with the blower not running. Inspected the furnace interior and performed electrical diagnostics with a true-RMS clamp meter to check amperage draw on the blower/inducer circuit and associated wiring, evaluating the gas valve and control wiring harness for proper operation. Findings were documented with photos.

Performed a heating tune-up on one 3-year-old furnace, including inspection of the ignition system and cleaning/servicing of the flame sensor, which showed light wear and discoloration but no breakage or corrosion. Verified safe, proper ignition and operation, and applied a furnace service sticker to the unit as requested.

Performed a heating tune-up on a Lennox condensing gas furnace, inspecting the cabinet, PVC intake/exhaust venting, condensate drain line, and ductwork connections for proper installation and condition, with no visible rust, leaks, or damage. Measured blower motor amperage with a true RMS clamp meter, recording 0.26 A, and verified the unit was operating normally.

Returned to address a water heater pilot light repeatedly extinguishing. Inspected the installation in the utility area and performed draft/pressure testing with a digital manometer to evaluate venting and combustion air conditions as a potential cause of the pilot outage. Verified readings and system operation, and documented the findings with photos.

Responded to a reported sewer vent pipe backup and inspected the exterior sewer cleanout and surrounding drain line, where wastewater was surfacing and running across the pavement. Evaluated the main sewer line for blockage and restricted flow, with the cracked, deteriorated pavement around the access cover noted as a possible contributing factor. Documented site conditions with photos for follow-up recommendations.

Performed a preventive maintenance tune-up on the furnace, inspecting the unit and verifying proper operation through a full heating cycle. Used a digital clamp meter to measure electrical draw and confirm components were operating within normal amperage range, and verified the thermostat was functioning and communicating correctly with the system.

Performed annual heating tune-up on two gas furnace systems, including inspection of the burner assembly, heat exchanger, ignition components, electrical connections, and safety controls, along with verification of proper combustion, airflow, and thermostat operation. Inspected the condensate drain piping and the Aprilaire whole-home humidifier, finding no visible damage, and noted residue staining on the floor near the condensate drain that should be monitored for leaks. Both systems were operating properly at completion.

Performed a heating tune-up on a 2010-model single-unit system, verifying thermostat operation (set and holding at 74°F) and checking ambient humidity and temperature readings near the unit with a digital hygrometer. Inspected the surrounding area and noted heavy rust staining and corrosion on the adjacent surface, which may indicate moisture exposure and should be monitored.

Responded to a main line backup and performed a main drain cleanout, using a drain machine with the appropriate cutting head to clear the blockage and restore full flow through the sewer line. Verified proper drainage by running water through the system and confirmed no remaining backup or standing water at fixtures. The work area was dense with stored items, so access was limited, and the area was left clean and in the same condition on completion.

Performed a heating tune-up on a 3-year-old gas furnace, removing the front access panel to inspect the inducer motor, pressure switch and tubing, gas valve and piping, burner compartment, and wiring connections. Verified thermostat operation by confirming a call for heat with the system set to Heat and the display reading 74° against a 78° setpoint, and the furnace is operating normally.

Completed heating tune-up maintenance on residential forced air furnace located in basement mechanical room. Performed comprehensive system inspection including burner assembly, heat exchanger, blower motor, and electrical connections. Replaced air filter and verified proper operation of all safety controls and venting components.

Completed comprehensive heating tune-up on 2013 basement furnace unit. Performed full system inspection including blower motor, control board, electrical connections, and air filter assessment. Conducted temperature diagnostics and verified all components operating within manufacturer specifications for optimal heating season performance.

Responded to no-cool complaint on ground-level unit U10 where system was unable to maintain setpoint of 72-74°F, with indoor temperature reading 77°F for two days following a recent offline event. Upon arrival, performed diagnostic evaluation of Carrier CVPVA4821XMCSAAA indoor section (manufactured June 2023) utilizing R-410A refrigerant with TXV metering device. Inspected unit components, verified system pressures, checked refrigerant charge levels, and assessed airflow performance to identify root cause of diminished cooling capacity.

Completed routine heating tune-up on 15-year-old Amana furnace system with no reported operational issues. Performed comprehensive inspection of all furnace components, verified proper combustion and airflow, checked gas connections and electrical systems, and inspected air filter condition. System found operating within normal parameters; all safety controls tested and confirmed functional.

Completed comprehensive furnace tune-up on basement unit, including full system inspection, filter evaluation, and thermostat functionality verification. All components operating within normal parameters, with Emerson digital thermostat responding properly to temperature commands. System prepared for heating season with no issues identified.

Completed comprehensive heating tune-up on 3-year-old furnace located in basement. Performed full system inspection including burner assembly cleaning, flame sensor maintenance, air filter evaluation, blower motor lubrication, heat exchanger inspection, and thermostat calibration verification. All components tested and operating within manufacturer specifications with no issues identified.

Replaced evaporator coil on second-floor air conditioning system. Unit had previously received a coil replacement in January, but required another coil change-out. Used refrigerant scale to properly charge system after installation, and retained original defective coil for warranty processing.

Completed preventive maintenance tune-up on Carrier furnace/air handler unit located in utility closet. Performed comprehensive system inspection, verified thermostat operation (Sensi model displaying proper temperature readings), and ensured all mechanical components were functioning within manufacturer specifications for optimal heating system performance.

Conducted site assessment for electric vehicle charging station installation in residential garage. Evaluated existing electrical infrastructure, wall framing, and optimal placement location for charging port relocation, providing detailed estimate as part of competitive bidding process.

# HVAC Tune-Up Completed Performed comprehensive preventive maintenance tune-up on two furnace units located in basement.
