ALL SYSTEMS HEATING AND COOLING
Rooftop Packaged Unit Installation in Dutchess County
Rooftop packaged units combine heating and cooling into a single self-contained system mounted on the roof, eliminating the need for ground-level equipment or extensive ductwork modifications. All Systems handles the complete installation process including structural assessment, roof penetration sealing, electrical hookup, ductwork connections, and full system commissioning to manufacturer specifications. We manage every aspect from initial load calculations to final testing, ensuring your packaged unit operates at peak efficiency and integrates seamlessly with your existing building systems.
Why Choose All Systems for Rooftop Packaged Unit Installation in Dutchess County
Rooftop packaged unit installation begins with a thorough building assessment to determine load requirements, existing ductwork capacity, and roof structural integrity. Our technicians perform Manual J load calculations to size the unit correctly for your heating and cooling needs, accounting for insulation, window placement, occupancy patterns, and local climate conditions. We then coordinate roof access, prepare penetrations with proper flashing and sealant to prevent leaks, secure mounting brackets to structural points, and establish ductwork connections that balance airflow throughout the building. / The installation process includes connecting refrigerant lines, running low-voltage thermostat wiring, and establishing electrical service from your panel to the unit with properly sized breakers and disconnect switches. We perform system evacuation and nitrogen purging to remove moisture from refrigerant lines, charge the system to manufacturer specifications, and test all heating and cooling cycles before leaving the site. / Final commissioning involves verifying thermostat operation, measuring airflow at supply registers, checking temperature rise and cooling capacity, and training building occupants on system controls. We clean up all debris from the installation, provide maintenance documentation, and explain seasonal filter changes and visual inspection points that extend equipment life and prevent costly failures.
Accurate Load Calculations for Proper Sizing
Undersized packaged units struggle to reach target temperatures while oversized units cycle on and off frequently, wasting energy and wearing components prematurely. We use Manual J calculation software to analyze square footage, insulation values, window solar exposure, internal heat loads, and outdoor design temperatures specific to your location. The result is a unit sized to deliver consistent comfort without energy waste, typically achieving 15 to 25 percent better efficiency than contractor guesses.
Sealed Roof Penetrations and Weatherproofing
A packaged unit on the roof means creating roof penetrations for drainage and condensate lines, creating a potential leak point if not executed correctly. We use heavy-duty flashing, elastomeric sealants rated for temperature cycling, and mechanical fasteners rated for wind uplift per local building codes. Each penetration is tested during commissioning to confirm no water intrusion occurs, protecting the building interior and the structural integrity of the roof below.
Refrigerant Evacuation and Charging Protocol
Moisture inside refrigerant lines causes acid formation, compressor failure, and loss of cooling capacity. We connect the system to certified evacuation pumps and nitrogen purge equipment, removing all air and moisture before introducing refrigerant. The system is then charged by weight per manufacturer data specific to your equipment model and ductwork configuration, verified with gauges on both high and low pressure sides. Proper charging prevents premature compressor failure and maintains peak efficiency throughout the equipment lifespan.
