Responded to investigate water leak reported near flue penetration after roofer ruled out roofing system as source. Performed thorough inspection of roof-mounted vent pipe and flue assembly. Documented measurements of the cylindrical metal duct pipe, which measured approximately 7 inches in diameter. Found deteriorated insulation wrap at top of pipe with visible fraying and wear. Identified compromised rubber boot flashing at roof penetration point with signs of age-related deterioration. Discovered significant rust and corrosion on square mounting flange and curb adapter at base of pipe assembly, with brown and orange oxidation present around edges. Noted deteriorating tan-colored coating on flange and aging black rubber gasket seal where pipe meets flange. Determined that water intrusion was occurring at the flue penetration assembly due to failed weatherproofing components rather than roof membrane. Photographed all findings for documentation purposes. Recommended replacement of det

Completed October Comfort Plan clean and check maintenance on 10 rooftop units and 5 garage heaters per scheduled agreement. Performed comprehensive inspection of all RTU electrical components, contactors, relays, and control boards with access panels removed for thorough evaluation. Inspected condenser coils, mechanical assemblies, and valve operations on all rooftop units. Examined garage heater burner assemblies, gas valves, ignition systems, and blower components to ensure proper operation ahead of heating season. Replaced 30 one-inch filters across all units as part of routine maintenance protocol. Verified all electrical connections, wiring integrity, and safety controls functioning properly throughout facility. All systems tested and confirmed operational with no deficiencies noted.

Completed prepaid commercial HVAC maintenance visit at mechanical room location. Replaced 20"x25"x4" media filter in Emerson Electro-air filtration system and verified proper unit operation upon completion.

Completed furnace clean and check maintenance per comfort plan agreement. Performed comprehensive system inspection including internal combustion chamber and heat exchanger examination using borescope camera to assess component condition and identify any potential issues. All accessible areas inspected and system found to be operating within normal parameters.

Completed fall Comfort Plan clean and check on single HVAC system, including inspection of air handler components and blower assembly. Replaced 15x20x1 air filter and verified proper system operation with temperature readings confirming adequate airflow and performance.

Completed commercial preventive maintenance agreement service on furnace and three ceiling-mounted unit heaters in industrial facility. Performed comprehensive cleaning and check procedures per contract protocol on all equipment, including inspection of gas valves, burner assemblies, and heat exchanger components. Documented equipment conditions with photographic evidence showing ceiling-mounted HVAC units with proper mounting and operational gas valve assemblies. Filter replacement information collected for proper sizing and quantity requirements to be billed separately per agreement terms.

Replaced defective gas valve on residential furnace unit under warranty coverage. Accessed furnace interior, disconnected electrical connections and gas supply line from failed valve assembly, removed old component, and installed new gas valve with proper torque specifications. Reconnected gas piping with brass fittings, restored all electrical connections, and performed leak test on gas connections to verify system integrity. Cycled unit through complete heating operation to confirm proper ignition sequence and burner operation. All systems functioning normally upon completion.

Responded to emergency gas leak call at furnace where utility company had already shut off gas supply. Upon arrival, inspected gas valve assembly and associated connections at the heating unit. Identified leak source, performed necessary repairs to gas piping and valve connections, and conducted pressure testing to verify system integrity. Restored gas service and confirmed proper operation of all safety controls and ignition components before returning unit to service.

Completed annual HVAC maintenance inspection on commercial rooftop unit and furnace system. Performed comprehensive tune-up procedures including visual inspection of all accessible components, checked electrical connections, verified proper operation of blower motor and condenser fan, inspected refrigerant lines and condensate drainage, and tested system controls for proper cycling. Unit operating within normal parameters at time of service with no immediate repairs required.

Completed warranty install inspection and documentation for HVAC system. Installed ceiling supply diffuser in commercial drop ceiling grid with proper alignment to existing acoustic tile layout and lighting fixtures. Observed evaporator coil assembly with excessive frost buildup during inspection, indicating potential airflow restriction or refrigerant charge issue requiring follow-up coordination with supervisor regarding insulation placement per warranty specifications.

Responded to no cooling complaint on commercial rooftop unit following power outage. Upon arrival, performed diagnostic assessment of affected AC system and measured supply air temperature at 153°F, confirming lack of cooling. Inspected rooftop condenser unit, electrical disconnect, and indoor air handler components to identify system failure caused by power interruption.

Removed existing York air conditioning unit from roof and completed installation of new 4-ton rooftop air conditioning unit with horizontal furnace mounted inside warehouse. Performed vacuum testing to verify system integrity, established proper refrigerant charge, and confirmed all ductwork connections and mechanical linkages were secure and operational.

Responded to service call for water leak at furnace system. Upon inspection, identified leaking PVC condensate drain piping connected to furnace with compromised purple primer joints at T-fitting connection. Documented existing outdoor condensing unit condition and indoor furnace piping configuration. Assessed PVC drainage system for proper slope and connection integrity at T-junction fitting where active leak was occurring.

Completed comprehensive clean and check maintenance on multiple HVAC systems including two split AC systems, two furnaces, and one hanging heater. Performed electrical diagnostics using clamp meter, verified amperage readings at 499 on outdoor condensing unit, and conducted temperature differential measurements across system components.
