About North Palm Beach
Manual J Load Calculation & Manual D Duct Design in North Palm Beach, FL.
Waterfront living changes the cooling load. A North Palm Beach home with sliding glass doors facing the canal, a screened porch that was later enclosed or a primary suite added in the 1980s can need far more cooling in some rooms than others, and a square-footage rule will never catch that. Swift runs Manual J load calculations in-house for the replacements and duct projects we install in North Palm Beach, measuring every room so the equipment and airflow match the way the house actually works. Many homes here have also been upgraded with impact windows and better roofs, which can lower the load and allow a smaller, better-matched system. In salty, humid coastal air, an oversized unit cools fast and leaves moisture behind, so getting the size right matters. The room-by-room numbers then drive a Manual D duct design that sends the right air to each space and keeps every bedroom within 3°F of the thermostat.
About this service
Manual J Load Calculation & Manual D Duct Design in North Palm Beach
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 North Palm Beach.
For a North Palm Beach Manual J, we measure each room and record window and door sizes, directions and glass types, with extra attention to the large waterfront openings that drive the load. We check ceiling heights, attic insulation and duct location, and we enter upgrades such as impact windows or a newer roof. Enclosed porches and additions are calculated on their own because they often have more glass and less insulation. The calculation produces each room's heat and moisture load. Manual S then guides the equipment choice, favoring systems that hold good dehumidification at lower speeds in coastal humidity. Manual D sizes every supply and return, including dedicated supplies for high-load waterfront rooms, and checks the total duct resistance against the blower. Manual T helps choose registers that wash air across large glass areas. For condos, we design within the building's limits. We review the plan with you and confirm the finished North Palm Beach system with airflow readings.

Got questions?
Frequently asked questions
They often do. Impact windows usually reduce solar heat and air leakage, which can lower the cooling load. If you've upgraded windows, doors or the roof since your last system went in, a new Manual J will show whether a smaller, better-matched system makes sense for your North Palm Beach home.
Manual J calculates that room's load from its actual glass area, direction and shading, so it gets the airflow it needs instead of the same duct as an interior bedroom. In the Manual D design, high-load North Palm Beach rooms like that often get a larger supply or a second register.
Yes. We run the Manual J for your unit, select equipment that fits the building's space and power limits with Manual S, and design the ducts within the available ceiling space using Manual D. We coordinate with your North Palm Beach condo association on any approvals needed.
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.
