# HVAC System Replacement Estimate Summary Responded to on-site service call to evaluate existing HVAC system for replacement. Conducted comprehensive assessment of outdoor condensing unit and indoor air distribution components. Exterior inspection revealed aging air conditioning condenser positioned on concrete pad adjacent to building structure, with existing refrigerant line set, electrical disconnect, and junction box requiring evaluation for replacement compatibility. Indoor assessment documented return air grille placement and existing ductwork configuration within conditioned space. Photographed current equipment installation, refrigerant piping routing, electrical connections, and indoor air handler access points to develop accurate replacement specifications. Provided Red-level priority estimate for complete system replacement with A+ equipment tier recommendations based on current system age, condition, and customer requirements for improved efficiency and reliability.

# Service Report Responded to no-cooling complaint on 15-year-old residential HVAC system. Customer reported thermostat set to 66°F but interior temperature remained at 72°F with warm air blowing from vents. No tripped breakers, no ice buildup on evaporator coil, and system fan operational. Upon arrival, conducted diagnostic assessment of split system located in attic space. Inspected air handler unit with spray foam insulated mechanical room and verified adequate airflow through return vent at floor level. Performed system evaluation including refrigerant pressures, electrical components, and airflow measurements to identify root cause of cooling failure on aging equipment. Given the system's age at 15 years and no-cool condition, provided customer with repair options and recommendations for restoring cooling function to residence with no secondary cooling source available.

Completed planned maintenance on an 8-year-old HVAC system under Platinum Level service agreement (first annual visit). Replaced 24x24x4 filter and documented significant corrosion with moisture accumulation at panel seams, indicating potential refrigerant leakage. Inspected utility room configuration including water treatment systems and associated ductwork to ensure proper system operation.

Responded to no-heat call for 15-20 year old Lennox Elite Series furnace located in damp basement environment. Upon inspection, discovered severely rusted blower motor assembly consistent with prolonged moisture exposure, preventing proper system operation.
