AC, Furnace & Plumbing Services in St. Charles, MO

Performed a heating tune-up on one furnace, including inspection of the system and replacement of the 16x25x1 pleated air filter to restore proper airflow. Verified thermostat operation by cycling the system in heat mode with the fan set to auto, confirming the unit responded to the call for heat and the system operated normally at completion.

Performed scheduled maintenance on a 20–22 kW Generac standby generator, including inspection of the system and associated electrical service components. Verified the utility meter, service entrance conduit, and main distribution panel, confirming breaker, lug, and conductor connections were secure and in sound condition, with all equipment found intact and operational.

Evaluated the scope for new receptacle installations in the unfinished basement, garage, and exterior, including assessment of the existing service entrance and meter enclosure. Inspected the basement's poured concrete foundation walls, vapor-barrier-covered framing, and exposed floor joist cavities to determine feasible routing for new branch circuits and surface-mounted conduit. Documented the exterior meter and service conduit conditions to support load evaluation and planning of GFCI-protected outlet locations.

Performed a seasonal tune-up on a 20-year-old gas furnace, including electrical testing with a digital clamp meter to verify component operation and amperage draw. Inspected the system and replaced the air filter with a new 20x25x4 3M Slim Fit pleated filter, installed per the airflow direction arrow, to restore proper airflow and system efficiency.

Performed a tune-up on two furnaces (under 10 years old) in the basement, inspecting the air handler cabinets and filter housings. Pulled and inspected the pleated air filters, which were mostly clean with no heavy debris buildup, and verified the condensate drain piping and floor drain area for proper drainage. Systems were left operating normally.

Cleared a slow-draining double-basin kitchen sink by removing the strainer baskets and inspecting the disposal, P-trap, and slip-joint drain assembly, then flushing the lines with water to confirm unrestricted flow with no leaks at the connections. Replaced the aging garbage disposal and reconnected the discharge elbow and drain plumbing. Removed the utility sink and capped off the associated lines.

Responded to a no-cool call on a single, under-one-year-old system. Inspected the air handler cabinet, including the control board (status LED active), low-voltage wiring harness and connectors, blower motor module, and cabinet insulation, and found no visible damage, loose connections, frost, or ice. Documented the condition of the control wiring and blower assembly for warranty records.

Performed a second-opinion diagnostic on a gas furnace reported to have a cracked heat exchanger. Removed the upper access panel and inspected the burner compartment, gas manifold, inducer assembly, and wiring harness, and documented the unit's condition with photographs. The unit shows no visible frost, ice, or major external damage, though dust and grime are present in the burner area, and an existing red-tag "STOP" notice remains posted at the unit.

Performed a seasonal heating tune-up on a 3-year-old Lennox furnace, inspecting the furnace interior, combustion components, wiring, and condensate/venting connections for proper operation. Also inspected the Aprilaire whole-house humidifier, confirming the unit, water supply line, and drain tubing were clean and in good condition with no rust or leaks. Noted whitish, crusty buildup and discoloration at the joints of the adjacent iron piping, which is recommended for further evaluation.

Performed a seasonal tune-up on one furnace, including inspection of system components and verification of heating operation. Checked the digital thermostat settings and confirmed proper heat call and fan function. Inspected the galvanized supply ductwork and flexible duct connections, noting surface rust at the seams and collar joints, with all collars secured by screws.

Replaced the failed heat exchanger on the furnace under warranty, resolving the no-heat condition. Removed the old heat exchanger, installed the new unit, and reconnected the gas valve and associated piping and wiring. Inspected the cabinet interior, which showed rust and corrosion around the heat exchanger access plate, and discarded the failed part.

Performed a heating tune-up on one furnace, removing the blower compartment access panel to inspect the control board, wiring harness, blower motor, and air filter. Measured blower motor amperage with a true RMS clamp meter, recording 6.70 A AC, and verified operation within normal parameters. Noted light dust and debris in the blower cabinet and confirmed wiring connections and safety labeling were intact.

Inspected the existing main electrical panel to evaluate whether it could support the addition of a tanked electric water heater. The panel interior was found to be congested and disorganized, with numerous conductors crisscrossed throughout the enclosure, some copper conductors showing fraying or splayed strands, and brittle insulation near the top of the panel. Given the panel's condition and limited available space, a panel replacement is recommended before installing the new water heater circuit, and the estimate was prepared for the customer's review.

Performed a heating tune-up on one furnace, including inspection of the flame sensor, which showed carbon buildup and tarnishing that can cause flame-sensing and ignition issues, and inspection of the 20x25 pleated air filter, which showed light dust loading and minor frame wear. Verified system operation and airflow, and noted past moisture staining and rust residue near the condensate drain piping and PVC fittings for monitoring.

Performed a heating tune-up on a 9-year-old furnace that was operating normally, inspecting the blower assembly, gas valve, wiring connections, and ductwork. Noted surface rust and corrosion around the inducer/blower housing mounting flange and lower seam, as well as on the gas supply pipe, and recommend monitoring these areas for further deterioration. System was left operational.

Delivered a replacement 20x25x4 pleated media air filter to the customer as part of their preventive maintenance agreement. The filter was left at the residence for installation, and no damage or defects were observed on the unit upon delivery.

Responded to a report of a rear-room electric baseboard heater producing insufficient heat while the bathroom unit operated normally. Inspected the circuit wiring and supply cabling in the accessible crawl space, which showed significant spray foam overspray on the framing and cables, and evaluated the baseboard heater's power delivery and operation to diagnose the reduced heat output.

Performed seasonal tune-ups on two systems, a furnace and an air conditioning unit, including inspection of the heat exchanger, burner assembly, condenser coil, and electrical connections, and verification of proper operation through heating and cooling cycles. Confirmed the smart thermostat was calling for heat and responding correctly to the setpoint, and verified the carbon monoxide monitor was installed and functional. Documented the equipment data plate and component condition with photos for service records.

Removed the existing UV lamp assembly from the supply plenum and sealed the resulting opening with a 10x10 sheet-metal access patch, secured with fasteners around the perimeter. Installed and commissioned the new APCO X air purification system, and recorded the unit serial number for warranty registration and inventory receiving.

Inspected the furnace and associated ductwork on the single unit, documenting findings with photos. Identified corrosion and rust staining along the galvanized supply trunk and elbow joints, including a cracked seam at a duct fitting with rust bleed-out that indicates air leakage and moisture-related deterioration. Recommend sealing or replacing the compromised duct section to restore proper airflow and system efficiency.
