Plumbing, Heating & Air Conditioning Service in Fenton, MO

Performed a heating tune-up on a 4-year-old Lennox gas furnace with an attached Aprilaire whole-house humidifier, inspecting the furnace components, venting, ductwork connections, and humidifier water supply and drain lines. All equipment was found in good condition with no visible signs of leaks, corrosion, or ice, and the system was left operating properly.

Performed seasonal heating maintenance on the furnace and replaced the 20x25x4 pleated air filter with a new one. Inspected the Aprilaire whole-home humidifier mounted on the supply duct, verifying the duct connection, wiring, water supply tubing, and drain line were intact and free of leaks, cracking, or corrosion. System left operational with no deficiencies noted.

Responded to a reported gas shut-off at the furnace due to a suspected failed gas valve and inspected the unit and associated black iron gas piping, shutoff valves, and flexible gas connector for leaks, corrosion, and proper connections. Documented the condition of the gas supply piping and valve assembly serving the system, and verified the supply was secured and safe at the time of service.

Rewired the existing fluorescent light fixture, including replacing the supply conductors and verifying proper connections at the fixture. Identified the corresponding circuit at the main breaker panel, confirmed circuit labeling, and tested the fixture for correct operation following the repair.

Returned to the site and cleaned the condensate drain lines, removing the heavy biological buildup and residue from the clear drain tubing that had restricted flow. Serviced the humidifier and reassembled the drain connections, verifying that the PVC fittings, tee, and clamp were secure and the drain assembly was free of blockage.

Responded to a partial circuit power loss, inspected the main service panel and branch circuit breakers, and traced the affected circuit to a GFCI receptacle that was loose and not seated flush in a damaged wall opening. Inspected the receptacle wiring and connections for faults or loose terminations, and restored power to the affected circuit. Note that the drywall around the device is torn, and the receptacle remains without a cover plate and requires proper securing and wall repair.

Replaced the failed compressor on the outdoor condensing unit under manufacturer parts and labor warranty, with the original unit retained per warranty requirements. After the swap, connected a digital manifold gauge set and verified system operation on R410A, with suction and discharge pressures stable and the unit running properly in both heating and cooling modes.

Responded to a non-responsive thermostat complaint on a two-unit system and inspected the Lennox S40 smart thermostat. The blank display was resolved and the unit is now powering on and showing normal system status, though the thermostat setup remains incomplete and requires finalizing through the manufacturer's setup process.

Responded to callback for an AC system not cooling. Inspected the outdoor condenser and found the coil fins coated with dirt, dust, and leaf debris, restricting airflow. Opened the electrical compartment and performed electrical diagnostics on the run capacitor and contactor using a clamp meter, noting loose, unterminated wire ends and cobweb debris in the control section. Documented findings with photos and recommended coil cleaning and wiring/component repairs to restore proper cooling operation.

Performed a heating tune-up on the furnace, including inspection of the blower and air handler cabinet, and verified electrical operation with a true RMS clamp meter, measuring approximately 6.2 A AC draw. Inspected the pleated return air filter and found it clean, with no visible damage, debris, or restriction. The system was left operating normally.

Completed heating tune-up on basement furnace unit. Performed comprehensive system inspection including burner assembly, heat exchanger, blower motor, and all safety controls. Verified proper thermostat operation and system cycling, confirmed gas valve functionality, and ensured all electrical connections were secure and within manufacturer specifications.

Completed comprehensive heating tune-up and maintenance on a 15-year-old Snyder furnace and 16-year-old Goodman unit located in basement. Performed full system inspection, verified proper ignition sequence and burner operation with clean blue flame pattern across all burners, tested safety controls including pressure switches, inspected electrical connections and wiring harness, checked thermostat operation and calibration, and confirmed all components functioning within manufacturer specifications. System operating safely and efficiently with no deficiencies noted at time of service.

Completed comprehensive tune-up service on 13-year-old furnace unit located in interior mechanical closet. Performed full system inspection, verified proper operation of air handler components, checked ductwork connections, and confirmed thermostat functionality with Nest control system. All equipment operating within normal parameters upon completion of preventive maintenance procedures.

Responded to callback for no cooling on Trane AC unit, same issue as previous visit where leak repair and recharge were performed. Upon arrival, inspected compressor, refrigerant lines, and condenser coil assembly. Verified system operation and assessed warranty eligibility for recurring cooling failure on 2-year-old unit.

Completed comprehensive heating tune-up on basement furnace unit, performing standard O10 maintenance protocol. Conducted electrical diagnostics using clamp meter and multimeter to verify amperage draws and system voltage readings, confirming all electrical components operating within manufacturer specifications. All safety checks passed, system tested and left in proper working condition.

Completed preventive maintenance tune-up on basement furnace unit. Performed comprehensive inspection of blower motor assembly, noting moderate rust and corrosion present on mounting hardware and fasteners. Verified all electrical connections, checked airflow, inspected ductwork, and confirmed system operational parameters are within acceptable range for continued service.

Responded to service call for intermittent lighting issues in multiple rooms requiring switches to be toggled several times before fixtures would illuminate. Inspected electrical system including main service meter and connections; documented existing electrical infrastructure with no visible damage or loose connections observed at meter enclosure. Customer advised that further diagnostic testing of interior switch circuits and fixture connections would be required to isolate the source of the intermittent operation.

Completed heating maintenance tune-up on 12-year-old furnace system. Performed comprehensive inspection of all heating components, verified thermostat operation at 71 degrees, inspected ductwork and condensate drain system in attic installation, and confirmed all equipment operating within normal parameters.
