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.

Completed warranty return visit to address thermostat programming and verify refrigerant charge on recently installed HVAC system.
