Plumbing, Heating, AC & Electrical Services in Madison, WI

Diagnosed a furnace short cycling issue where the unit would shut down immediately after ignition. Found the pressure switch hose loose and reconnected it, then verified the pressure switch ports were clear of obstruction. Performed a basic cleaning and system check, and confirmed the furnace now completes normal heating cycles.

Performed a prepaid maintenance visit on the Lennox gas furnace, including cleaning and a full operational check of the unit, flue connection, gas piping and shutoff valve, and condensate/PVC drain line. Inspected the Honeywell bypass humidifier, humidistat, and associated drain and supply tubing at the supply plenum, and verified the ductwork and refrigerant line connections showed no signs of rust, frost, or damage. Equipment was found in good working condition and operating normally at the conclusion of the visit.

Performed a heating maintenance tune-up on a 4-year-old Goodman gas furnace, including cleaning and a full operational inspection of the unit. Verified the condition of the PVC intake/exhaust venting, condensate drain line, gas piping and shutoff valves, and electrical connections, with the unit operating normally and no deficiencies noted.

Diagnosed a no-heat condition on a 10-year-old furnace and found a large hole in the flue vent connector at the chimney, creating a combustion venting hazard. Installed a new chimney liner and re-vented the furnace and water heater into the new liner, then restored both appliances to operation and verified proper heat output.

Performed a boiler tune-up and safety inspection, including a combustion analysis of the flue gases with a digital analyzer, and checked the gas train, controls, and pressure gauge for proper operation. Noted a heavily stained and sediment-filled water sight glass and corroded fittings, and recommend glass replacement and further evaluation of the system piping.

Performed a furnace clean and tune-up on a gas furnace in a basement mechanical space, including inspection of the cabinet, PVC intake/exhaust venting, ductwork connections, and electrical conduit. Inspected the refrigerant line set, insulation, and connections at the air handler panel and confirmed no frost, ice, or active leaks. The system was checked and found in good condition, ready for the facility's state inspection requirements.

Diagnosed a 41-year-old furnace exhibiting a clunking noise and short-cycling shutdowns. Inspection of the supply plenum and ductwork revealed heavy frost and condensation buildup on the galvanized sheet metal, along with surface rust on the adjacent support framing, indicating age-related deterioration. Due to the unit's age and condition, replacement was recommended, and the customer has scheduled a follow-up in-home estimate for a new system.

Gained access to the Burnham Independence boiler by forcing open the thermostat lock box, as no key was available. Replaced the non-functioning pressure gauge and tested system operation. The boiler ran, but the new gauge still showed no pressure reading, so the cause of the missing reading remains unresolved and further diagnosis of the gauge connection or system is recommended.

Performed a seasonal tune-up on a 2019 Lennox 70,000 BTU furnace, including a cleaning and full operational inspection. Verified safe, efficient combustion using a calibrated combustion analyzer, with flue gas readings of CO at 7 ppm, CO2 at 6.9–7.0%, and O2 at 8.7%, all within normal operating range. The furnace is operating properly and is ready for the heating season.

Performed prepaid maintenance inspection and cleaning of the heating and cooling system. Measured temperature differential at 20°F in cooling mode and 34°F in heating mode, both within normal operating range. Testing revealed the capacitor reading 25 µF versus the 30 µF rating, so it was replaced, and the unit was verified to operate properly.

Performed a tune-up on a 2016 Goodman gas-fired furnace, including cleaning and inspection of the burner compartment, gas piping, wiring, and condensate drain system, and replaced the air filter. Noted surface corrosion on the gas piping and debris buildup around the furnace base, and verified the unit was operating properly upon completion.

Responded to a furnace water leak complaint and found the condenser coil heavily soiled. Cleaned the condenser coil and ran the system to verify operation. Noted corrosion on the brass refrigerant service valve and fittings, along with rust and moisture staining on the surrounding cabinet panels.

Responded to a no-cooling complaint on a 1985 A/C system that was tripping the fuse at the disconnect. Inspected the Ducane gas furnace/air handler, ductwork, and associated condensate drain, gas, and electrical connections, and found no visible rust, frost, or major damage at the indoor unit. The repeated fuse failure indicates an electrical fault in the aged outdoor condensing unit, likely a shorted compressor, failed capacitor, or shorted contactor. Given the system's age, further diagnosis and repair or replacement options are recommended.

Responded to a no-heat call on a 2022 Lennox gas-fired furnace, verifying operation with the smart thermostat and performing a basic cleaning and safety check of the unit. Combustion analysis was performed with a handheld analyzer, showing CO at 12–14 ppm, CO2 at 5.3%, and O2 at 11.6%, confirming the furnace is firing and operating within safe combustion parameters. Electrical measurements were taken with a clamp meter, and the furnace was left operating normally.

Performed a cleaning and operational inspection on the Goodman furnace, including a basic cleaning of accessible components and verification of safe, proper operation. Conducted combustion analysis with a calibrated analyzer, recording CO at 21-22 ppm, CO2 at 5.3%, and O2 at 11.6%, with all readings within acceptable operating parameters. No deficiencies or required repairs were identified during the service.

Performed a boiler tune-up and safety inspection, including cleaning and checking the unit's components and operation. Inspection of the flue vent connection at the masonry wall revealed significant rust and corrosion at the pipe collar with perforations and deteriorated surrounding mortar, which should be repaired or replaced to ensure safe venting.

Responded to a leaking A/C unit and found the condensate drain was clogged, causing water to leak inside the furnace cabinet. Cleared the blockage and cleaned the drain assembly to restore proper condensate drainage. Performed a brief furnace tune-up while on site.

Diagnosed a no-heat and no-cooling call with a thermostat displaying "No Power" despite fresh batteries, and found the thermostat wiring had been incorrectly terminated. Rewired the Honeywell thermostat to the proper terminals, restoring power to the display, then cycled the system and confirmed the Ruud Silhouette II furnace started and ran a normal heating cycle. Inspected the furnace and air filter during the visit, with no additional issues noted.

Replaced the boiler sight glass and installed a new pressure gauge. The old gauge snapped off at the fitting, so the corroded, rust-packed remainder was drilled out and the port re-threaded with a tap to accept the new gauge. Both the new gauge and the existing pressure control (pressuretrol) gave inaccurate readings, with the gauge showing 5 psi on a dry system. The pressuretrol tab was adjusted to restore operation, but actual cut-out pressure could not be verified, so further diagnosis and gauge or control replacement are recommended.

Performed a routine furnace tune-up, including basic maintenance and inspection of the unit. Verified safe, efficient operation using a Testo 310 combustion analyzer, with readings of 4.8% O₂, 9.02% CO₂, and 5.4 ppm CO, all within normal operating parameters.
