Completed fall preventative maintenance on commercial Trane rooftop unit per contract agreement. Performed comprehensive system inspection, checked refrigerant temperatures reading 20.2°F, verified filter condition, and documented equipment nameplate information. All components operating within normal parameters with no deficiencies noted at time of service.

Completed new construction HVAC installation including furnace and ductwork system in crawl space. Installed main trunk line with galvanized metal ductwork properly supported from floor joists, along with flexible branch connections for distribution throughout the structure. Applied vapor barrier ground cover for moisture control and installed reflective insulation on foundation walls per code requirements. Exterior work included installation of PVC condensate drain system with proper trap configuration mounted to building exterior, ensuring adequate drainage away from foundation. All ductwork sealed and secured, system ready for startup and commissioning.

Responded to a water leak located under the kitchen sink. Upon inspection, identified the garbage disposal unit as the source of the leak. The existing disposal showed signs of failure at connection points and required replacement. Documented the faulty unit and surrounding plumbing configuration, including the dishwasher drain connection via corrugated hose, PVC discharge piping, and water supply lines. Provided photographic documentation of the defective disposal and cabinet interior for service records.

Completed rough-in installation for new construction HVAC system, including furnace and air conditioning unit placement and ductwork distribution throughout the structure. All equipment was positioned according to specifications and duct runs were installed to ensure proper airflow and system efficiency.

Responded to commercial callback for inoperative condenser fan. Replaced failed condenser fan motor on rooftop HVAC unit and restored system to normal operation. Unit tested and confirmed proper airflow and cooling function upon completion.

Completed spring maintenance on three commercial rooftop units (100, 200, 300) per contract agreement. Performed comprehensive preventive maintenance including filter inspection, coil cleaning, refrigerant line assessment, and electrical connection verification. Units 100 and 200 exhibited heavy debris accumulation on condenser coils and filter screens requiring thorough cleaning to restore proper airflow and heat transfer efficiency. Removed dirt, pollen, and organic matter buildup from mesh panels and top surfaces. Inspected refrigerant lines for proper insulation and secure mounting, noting some algae growth on exterior piping requiring attention. Verified fan operation and checked all mounting hardware for security. All three units tested operational upon completion with improved airflow and no refrigerant leaks detected.

Responded to no cooling complaint on residential HVAC system. Upon arrival, inspected unit and PCB components in basement mechanical area. Diagnosed issue with printed circuit board causing system failure. Replaced defective PCB, verified proper electrical connections, and tested system operation. Unit restored to full cooling capacity with all safety controls functioning properly.

Completed comprehensive spring maintenance on residential HVAC system including Ultra 80 furnace and associated cooling equipment. Performed full system inspection of mechanical components, ductwork, and auxiliary equipment including humidifier and water treatment devices. All units tested and verified operational for upcoming cooling season.

Responded to no cooling complaint in patient room on 3rd floor with thermostat set at 67°F but reading 71°F. Inspected HVAC unit, verified temperature readings with digital thermometer, and examined internal components including blower assembly, wiring connections, and control board. System was found to have operational issues that were addressed, restoring proper cooling function to the space.

Responded to water leak complaint at diffuser. Upon inspection, found evidence of significant condensation and moisture accumulation on blower assembly and surrounding components. Documented conditions with photos showing water droplets on blower housing and moisture staining on ductwork. System appears to have drainage or insulation issue causing condensate to reach diffuser instead of draining properly through designated drain lines.

Completed full HVAC system retrofit installation including new furnace and air conditioning condenser unit. Positioned outdoor AC unit against exterior brick and wood siding with proper clearances, installed refrigerant line set, established electrical disconnect, and mounted unit on stable pad. System installed per manufacturer specifications with all components operational and ready for use pending completion of financing documentation.

Responded to no cooling complaint on rooftop unit. Found system low on refrigerant charge.
