Responded to no airflow complaint on 10+ year old air conditioning system. Upon arrival, confirmed outdoor compressor was running but indoor unit was not delivering conditioned air to living space. Measured supply air temperature at register showing 65.4°F, indicating inadequate cooling performance. Inspected attic installation and identified failed or disconnected supply duct at plenum connection. Flexible ductwork was found completely detached from main trunk line, causing all conditioned air to dump into attic space rather than reaching occupied areas. Reconnected supply duct to plenum and secured connection properly. Verified airflow restoration at registers and system operation returned to normal. Customer declined further repairs at this time.

Responded to callback for excessive noise from newly installed HVAC unit. Upon inspection, discovered loose electrical connection in control panel causing vibration and audible humming that intensified during operation. Secured wire connections with proper wire nuts, verified capacitor mounting, and tested system operation. Unit now running quietly with no abnormal sounds detected.

Completed full HVAC system replacement in residential basement mechanical room, including installation of new furnace unit with proper ductwork connections and plenum integration. Installed condensate pump, fan-powered humidifier, surge protector, and Ecobee thermostat to provide complete climate control functionality. All equipment properly mounted, vented with PVC piping, and connected to existing ductwork system with metal transitions, ensuring efficient airflow and system operation.

Conducted comprehensive evaluation of 24-year-old Carrier R22 air conditioning system with intermittently failing condenser fan motor. Assessed outdoor condenser unit housed in wooden lattice enclosure and inspected indoor ductwork and plenum assembly in basement mechanical space. Provided detailed replacement estimate for complete AC system upgrade due to obsolete R22 refrigerant phase-out and deteriorating condenser fan motor requiring full system replacement rather than repair of aging equipment.

Responded to service call for AC unit not cooling and making noise upon startup. Inspected outdoor condensing unit and found electrical connections at contactor showing signs of wear and outdoor exposure. Examined capacitor, contactor assembly, and associated wiring within electrical compartment. All wire connections were secured and terminals cleaned. Verified proper voltage and amperage at contactor. Capacitor tested within acceptable range. Unit cycled successfully with normal operation restored and noise eliminated upon startup.

Completed comprehensive cooling check on dual-zone HVAC system consisting of two air handlers and two condensing units per maintenance agreement. Performed electrical diagnostics including amperage readings on compressor and fan motors using digital clamp meter, verified all components operating within manufacturer specifications, and inspected refrigerant circuit connections and safety controls with all systems found to be functioning properly.

Performed comprehensive estimate for replacement of 24-year-old air conditioning system utilizing obsolete R22 refrigerant. Evaluated existing outdoor condenser unit and assessed current installation location, clearances, and refrigerant line configuration. Discussed customer's interest in relocating condensing unit to more optimal position and installing new refrigerant line set to accommodate modern equipment specifications and improve system efficiency.

Completed cooling check on two air conditioning systems. Replaced air filters with 16x20x1 and 16x25x1 filters, performed general service inspection, and conducted change-out-the-winter preparation to ensure both HVAC units are operating efficiently for the upcoming season.

Completed scheduled maintenance agreement inspection on residential split HVAC system consisting of condenser unit and air handler located in attic space. Performed comprehensive visual inspection of air handler control board and power supply components, verifying proper operation of all electronic circuits, connections, and safety systems. Documented equipment condition through photographic records showing control board assembly with intact heatsinks, toroidal inductors, wire harnesses, and digital display functioning normally. Inspected attic-mounted air handler installation, confirmed adequate clearances, proper insulation placement around unit, and verified all manufacturer labels and specifications were legible and intact for future reference.

Completed commercial HVAC maintenance agreement service on rooftop RTU cooling system, two water heaters with circulating and booster pumps. Replaced air filters including two 16x20x1 and one 16x25x1 units, performed system inspection and documentation of all equipment.

Responded to no-cooling complaint on newly installed Mitsubishi mini-split system. Upon arrival, verified electrical connections at disconnect box were properly terminated and system had successfully held vacuum during installation. Investigated 25-foot line set installation and confirmed refrigerant charge levels were at factory pre-loaded specifications. Conducted diagnostic testing of outdoor condensing unit and indoor air handler using manifold gauges to assess refrigerant pressures and system operation. Identified issue preventing cooling mode engagement and performed necessary corrections to restore proper system functionality. Unit tested and confirmed operating within manufacturer specifications upon completion.

Completed routine HVAC maintenance agreement service, including system inspection and replacement of 16x20x1 air filter. Verified thermostat operation and documented equipment condition with photographic records showing proper system functionality.

Completed cooling check on two condenser units as part of scheduled maintenance agreement. Verified system operation, measured supply air temperature at 13.5°F split across vent register, and inspected blower wheel assembly for cleanliness and proper function. All components operating within normal parameters with no deficiencies noted.

Responded to system fault high humidity alert on recently installed thermostat. Accessed fan coil airflow settings and adjusted dehumidify parameters from high to comfort mode. Verified supply air temperature at air handler reading 55°F, confirming proper system operation and resolving the false humidity warning.

Returned to property to investigate reported water leak in HVAC system. Upon inspection of attic space, located flexible supply duct with intact insulation wrapping and adjacent PVC condensate drain line. Examined surrounding areas and discovered deteriorated paper-backed insulation material on attic floor showing significant moisture damage, discoloration, and breakdown. Material exhibited yellowing, flaking, and crumbling consistent with previous water exposure. Documented conditions with photographs showing affected insulation and HVAC ductwork configuration. No active water leak detected at time of inspection from condensate drain line or ductwork connections. Recommended monitoring system for future leaks and advised replacement of damaged attic insulation to restore proper thermal efficiency.

Responded to no hot water complaint on tanked water heater system. Upon arrival, observed blower motor cycling with 3-flash error code indicating thermal cutout (TCO) or pressure switch failure in open position. Diagnosed faulty pressure switch preventing proper ignition sequence. Replaced defective pressure switch assembly and verified proper venting and combustion air supply. Tested unit through multiple heating cycles to confirm reliable ignition, proper flame operation, and hot water delivery restored to normal function.
