Upon arrival, found multiple outdoor condensing units installed on rooftop area. Performed diagnostic evaluation of the multi-zone HVAC system to identify cause of inadequate cooling in upper levels and documented equipment conditions with photos for service records.

Responded to no cooling complaint on second and third floors with significant temperature differential (thermostat set to 65°F but reading 78-80°F). Performed diagnostic evaluation of multi-zone HVAC system consisting of dual furnace units in mechanical room and three outdoor condensing units. Assessed system configuration, zoning controls, refrigerant lines, electrical connections, and ductwork distribution to identify cause of inadequate cooling in upper levels and provided full system replacement estimate.

Completed comprehensive air conditioning tune-up on a 6-year-old outdoor condensing unit. Removed top panel to access condenser coil, which exhibited significant accumulation of dirt, dust, debris, and organic growth with yellowish-green discoloration throughout the fin surfaces. Thoroughly cleaned condenser coil to remove buildup and restore proper airflow and heat transfer efficiency. Performed standard maintenance inspection of all accessible components, reassembled unit, and verified proper operation upon completion.

Completed full HVAC system installation in basement utility area, replacing existing equipment with Trane 6/16 SL280 two-stage variable speed furnace and EL15 single-stage air conditioner, upgraded to 16 SEER efficiency rating. Installed all necessary ductwork connections with metallic silver transitions and elbow joints from furnace unit. Connected electrical wiring and mounted control components on concrete block wall. Applied Lennox instant rebate program and included complimentary water heater installation as part of system upgrade package. Verified all mechanical connections, tested system operation for proper heating and cooling cycles, and confirmed variable speed blower motor functionality. All equipment installed to manufacturer specifications with proper clearances maintained around furnace unit and associated components.

Completed installation of 75-gallon tanked water heater in basement utility area. Initial unit was damaged at the top upon delivery and required return to Ferguson for replacement. Successfully installed replacement unit with proper copper piping connections, secured all water supply lines, and verified system operation with no leaks detected.

Replaced defective TXV metering device in cooling system under manufacturer's warranty and installed a Quiet Check Valve on the sump pump discharge line. System pressures were verified using calibrated manifold gauges, confirming proper refrigerant charge and operational parameters post-repair.

Responded to callback for A/C unit experiencing issues and water leakage following previous service visit. Performed diagnostic inspection of system components in attic installation space. Investigated condensate drain system and evaluated PVC drain line routing. Measured ductwork clearances and assessed flexible duct connections to identify potential moisture intrusion points. Documented HVAC system configuration and drainage assembly with detailed measurements to determine if current issues were related to prior service work or represented new system concerns.

Completed comprehensive BFMA preventive maintenance tune-up on dual outdoor condensing units. Performed standard inspection procedures including cleaning condenser coils, checking refrigerant levels, testing electrical connections, and verifying proper system operation. Both units found to be functioning within normal parameters with no immediate service concerns identified.

Completed furnace replacement in crawl space serving sunroom addition, installing Lennox EL297UH045XV36BK high-efficiency unit.
