About Jensen Beach
Manual J Load Calculation & Manual D Duct Design in Jensen Beach, FL.
With the ocean on one side and the Indian River Lagoon on the other, Jensen Beach homes deal with sun on the water, salty breezes and humidity nearly year-round. Rooms facing the lagoon or the beach often have large windows and sliding doors that drive the cooling load, while older cottages near Pineapple Avenue may have little attic insulation and original windows. Remodels and additions have changed many homes over the decades. Swift runs Manual J load calculations in-house for the systems and duct projects we install in Jensen Beach, measuring each room so the equipment fits the home as it stands. Getting the size right matters for moisture as much as temperature here. An oversized system cools fast and leaves the air damp, while a properly sized one runs long enough to dry the house. The room-by-room loads also feed a Manual D duct design that delivers 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 Jensen 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 Jensen Beach.
In Jensen Beach, the Manual J starts with the water-facing side of the house, where large windows and sliding doors usually carry the biggest loads. We record every opening by size, direction and glass type, measure each room and its ceiling height, check the attic insulation and note where the ducts and air handler are. Additions and enclosed porches are calculated as their own spaces. For condos, shared walls and floors are part of the input. Once the heat and moisture loads are known, Manual S guides us to equipment that handles both, with good dehumidification at lower speeds for a coastal home. Manual D then sets the supply and return sizes, places returns so bedrooms stay connected when doors close and keeps the total duct pressure within the blower's capability. Manual T helps choose registers that push air across wide glass walls. We share the plan with you before any work, then confirm the airflow and temperatures in your Jensen Beach home once the system is running.

Frequently asked questions
We calculate the load of each room from its actual window and door area, direction, glass type and shading. Water-view rooms in Jensen Beach often have large openings and carry heavy afternoon loads. Manual J captures that, so those rooms get enough capacity and airflow instead of being treated like an interior bedroom.
Manual J calculates the moisture load along with the heat load. In Jensen Beach, with water on both sides, that moisture load is significant. Manual S then selects equipment that removes it well, so the house feels dry and comfortable instead of cool and clammy.
Yes. We run the Manual J on the cottage as it will be after the renovation, including new windows, insulation and any added rooms, then design the ducts with Manual D and recommend equipment with Manual S. Planning it early keeps your renovated Jensen Beach cottage comfortable in every room.
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.
