About Palm Beach Gardens
Manual J Load Calculation & Manual D Duct Design in Palm Beach Gardens, FL.
Sizing equipment for a Palm Beach Gardens home takes more than square footage. Two-story foyers, walls of glass facing the golf course or the water, summer kitchens, lanais that open to the living room and rooms that sit unused for months all change how much cooling a house needs and where it needs it. Swift runs Manual J load calculations in-house for the systems and duct projects we install in Palm Beach Gardens, measuring every room so the equipment and airflow match the house. The room-by-room numbers also answer bigger questions: whether one system with zoning is enough, whether a second air handler would serve a far wing better, and how much capacity a variable-speed system really needs to hold humidity in check at low speed. From there, a Manual D duct design sizes each run to deliver the right airflow, so every bedroom stays within 3°F of the thermostat. It is the same disciplined process whether the home is in Old Palm or off Burns Road.
About this service
Manual J Load Calculation & Manual D Duct Design in Palm Beach Gardens
Most air conditioners in South Florida were sized with a rule of thumb, so many tons for so many square feet, or simply matched to the unit they replaced. That shortcut ignores what really drives the load in a Florida home: window area and direction, glass type, shading, insulation, ceiling heights, duct location, air leakage and the moisture the system has to remove. An oversized system cools fast, shuts off and leaves the house clammy. An undersized one runs nonstop. And without a duct design, even a perfectly sized system can't get the right amount of air to each room.
Swift Air Conditioning does this work in-house, using the ACCA standards. Manual J is the room-by-room heating and cooling load calculation. Manual S uses those loads to select equipment with the right capacity and enough moisture removal for our climate. Manual D designs the duct system, sizing each supply, trunk and return so the blower can deliver the airflow each room needs. Manual T guides the choice of registers and grilles so the air mixes well in every room.
The design target is the comfort guideline in ACCA's Manual RS: each room within 3°F of the thermostat while cooling. We build every replacement and duct project to the design, then measure airflow and temperatures after installation to confirm it performs.
Florida's energy code calls for heating and cooling equipment in new homes to be sized with Manual S from a Manual J load calculation, and the residential code points to Manual D for duct design. We bring the same discipline to replacements, additions and renovations, because it's what makes a home comfortable. Call (561) 685-8408 to schedule an in-home visit.

Local details
Manual J Load Calculation & Manual D Duct Design details for Palm Beach Gardens.
A Palm Beach Gardens Manual J starts with a detailed survey. We measure each room, including tall spaces like foyers and great rooms, record every window and door by size, direction and glass type, note shading from overhangs and landscaping, check insulation and locate each air handler and duct system. Rooms that open to lanais or summer kitchens are accounted for separately. The calculation gives each room's heat and moisture load. Manual S uses those loads to select equipment, paying close attention to the capacity range of variable-speed and two-stage systems so they dehumidify well at low speed. Manual D then designs the ducts for each system or zone, sizing supplies, returns and trunks against the blower's available pressure, and Manual T guides register and grille selection for rooms with high ceilings. If your plans include a renovation or addition, we design for the finished home. After installation, we verify each Palm Beach Gardens system with airflow and temperature readings.

Frequently asked questions
It depends on the layout and loads. A room-by-room Manual J shows how much cooling each area needs and when. For a home with a far guest wing or a second floor with very different loads, two systems may be simpler and more reliable than complex zoning. The calculation for your Palm Beach Gardens home makes the choice clear.
Tall spaces have more wall and glass area, and warm air collects up high, so they carry a bigger load than their floor area suggests. Manual J accounts for the actual volume and window area, and Manual T helps choose registers that mix the air instead of leaving a hot layer near the ceiling in a Palm Beach Gardens great room.
Yes. We run the Manual J on the home as it will be after the work, then design the ducts with Manual D and select equipment with Manual S. That way the new space is part of the plan instead of being tapped onto an existing duct. Share your Palm Beach Gardens plans with us early and we'll design around them.
Manual J is the ACCA standard for calculating how much heating and cooling each room of a home needs. It accounts for walls, windows and their direction, glass type, shading, insulation, ceiling heights, duct location, air leakage and occupants, and it calculates the moisture load as well as the heat load.
Manual J calculates the loads. Manual S selects equipment that matches those loads, including enough moisture removal. Manual D designs the duct system that delivers the right airflow to each room, and Manual T guides register and grille selection. Used together, they produce a system that's sized right and delivers air evenly.
