Reinstalled the outdoor condenser unit on its pad and reconnected the refrigerant line set, rebrazing the copper joints to the service valves. Connected manifold gauges and temperature clamps to pressurize the system, check for leaks, and verify proper operation and refrigerant line temperatures. Noted the existing line set insulation is frayed and degraded and should be replaced.

Performed pump down procedure on residential AC condenser unit located near electric meter, recovering refrigerant into the condenser for system preservation. Disconnected and removed condenser unit from gravel pad adjacent to building foundation to facilitate property work. Unit secured for reinstallation upon completion of exterior renovations. Coordinated with customer for service timing and confirmed work scope as first phase of two-part project.

Completed comprehensive BFMA tune-up service on 11-year-old furnace system including full inspection of heating components, blower assembly, and heat exchanger. Performed humidifier maintenance with #35 pad replacement and utilized inspection camera to verify ductwork integrity and internal system conditions through attic access point. All equipment tested and confirmed operational with recurring maintenance services established for continued system performance.

Responded to service call for boiler system requiring glycol addition. Picked up glycol from headquarters and proceeded to location. Upon arrival, inspected the heating system boiler unit with green top section and gray body, noting the circular pressure gauge and existing plumbing connections. Successfully added glycol to the boiler system to ensure proper freeze protection and heat transfer efficiency. Verified system pressure readings on gauge after glycol addition. Documented equipment condition with photographs showing the boiler unit, associated copper piping, brass valves, and electrical connections. System operational upon completion of service.

Completed comprehensive BFMA tune-up service on 7-year-old heating system including furnace and boiler maintenance. Performed full system flush and refilled with fresh glycol solution throughout entire hydronic heating system. Inspected and serviced garage heater unit, verified all connections, pressure gauges, and operational components. Evaluated sump pump system responding to audible alarm condition and assessed functionality. All equipment tested and confirmed operating within manufacturer specifications upon completion.

Completed installation of two UV light assemblies to enhance indoor air quality and sanitization within the HVAC system. Applied reflective foil insulation to second floor ductwork to improve thermal efficiency and reduce heat transfer in the attic space. All components were properly secured and tested for optimal performance.

Performed comprehensive duct cleaning on two separate HVAC systems. Pre-service inspection revealed heavy accumulation of dust, debris, and particulate matter throughout the ductwork, with significant buildup on interior surfaces, seams, and ceiling portions showing dark discoloration from extended use without maintenance. Thoroughly cleaned all accessible ductwork using professional equipment to remove contaminants and restore proper airflow efficiency.

Responded to after hours call for no heat condition. Upon arrival, found blown fuses in outdoor disconnect serving HVAC system. Replaced two cylindrical fuses in fuse holder and verified proper electrical connections at junction box. Inspected furnace interior components including gas line connections, ductwork, and control wiring. System tested and restored to normal operation.

Completed comprehensive BFMA tune-up on newly installed HVAC system consisting of two air conditioning units, two furnaces, and two humidifiers, all less than six months old. Performed full system inspection and maintenance protocol on all equipment with no trouble found; all units operating within manufacturer specifications and performing as expected.

Replaced faulty motor drive assembly on HVAC unit after diagnosing control board and motor component failure. Staged replacement parts were installed, electrical connections were properly terminated using wire nuts, and all wiring was secured to circuit board terminals. System was tested and restored to full operational status.

Responded to emergency no-cool call on recently installed residential air conditioning system affecting entire home. Upon arrival, performed diagnostic testing on 2-3 month old AC unit using multimeter and gauge set to identify system failure. Inspected air handler, evaporator coil assembly, and furnace components with panels open to access internal wiring, circuit boards, and mechanical systems. Verified electrical connections at junction box and control boards, checked condensate drain lines and PVC piping configuration, and tested system operation. Documented equipment condition and diagnostic findings with photographic evidence of internal components and testing procedures performed on the HVAC installation.

Completed routine BFMA tune-up on two furnaces with no reported issues; both systems operating normally. During inspection, identified failed thermal fuse component which was replaced to ensure continued safe operation. All systems tested and confirmed heating properly upon completion.

Replaced failed inducer motor and ignitor assembly on residential boiler system. Verified proper operation of combustion blower and ignition sequence upon startup, ensuring safe and efficient heating system performance.

Responded to repeat no cooling call with senior technician. Upon arrival, found Infinity thermostat displaying Error 177.04, indicating communication failure between control board and system components. Inspection of air handler revealed significant corrosion and rust damage on metal housing surrounding control board assembly, with moisture intrusion evident throughout cabinet. Corroded metal surfaces and deteriorated cabinet condition compromising electrical connections and contributing to intermittent system failures. Documented control board wiring connections and cabinet condition with photos. Error code and physical damage indicate need for control board replacement and cabinet repair or replacement to resolve recurring cooling failures.
