About Tequesta
Manual J Load Calculation & Manual D Duct Design in Tequesta, FL.
In Tequesta, the view often decides the cooling load. Homes along the Loxahatchee River and the Intracoastal tend to have large windows and sliding doors facing the water, and rooms on that side work much harder than the rest of the house. Older ranch homes in the village core may have added Florida rooms or enclosed porches, while newer homes in Cypress Creek have better windows and insulation and may need less capacity than their size suggests. Sizing by square footage misses all of that. Swift runs Manual J load calculations in-house for the systems and duct projects we install in Tequesta, so equipment is matched to how each home actually gains heat and moisture. That room-by-room picture also shapes a Manual D duct design that gives the high-load rooms more air and keeps every bedroom within 3°F of the thermostat. In humid riverfront air, correct sizing matters for moisture control as much as for temperature.
About this service
Manual J Load Calculation & Manual D Duct Design in Tequesta
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 Tequesta.
The Manual J for a Tequesta home starts with measuring each room and recording every window and door by size, direction and glass type. Riverfront and Intracoastal rooms with large openings get special attention, as do enclosed porches and Florida rooms. We check ceiling heights, attic insulation and duct location, and include upgrades like impact windows. With those inputs, we work out how much heat and moisture every room takes on. Manual S uses those loads to choose equipment with the right capacity and solid dehumidification, so the house stays dry in waterfront humidity. Manual D turns the loads into duct sizes, with dedicated, properly sized supplies for the rooms that face the water and return paths for every bedroom, and checks the total duct resistance against what the blower can deliver. Manual T guides register choices. We go over the design with you before work starts, and after installation we verify the airflow in every room of your Tequesta home.

Got questions?
Frequently asked questions
Large windows and sliding doors let in a lot of solar heat, especially when they face south, east or west. Manual J calculates each room's load from its actual glass area and direction, so riverfront rooms in Tequesta get the airflow they need instead of the same duct as an interior bedroom.
Yes, and it often does after upgrades. Impact windows, a newer roof or added insulation can lower a Tequesta home's load. A right-sized system runs longer cycles, controls humidity better and usually costs less to run than an oversized one that short cycles. We will show you the room-by-room numbers so you can see why.
Yes. Enclosed porches and Florida rooms usually have more glass and less insulation than the rest of the house, so they carry a higher load. We calculate them separately in the Manual J and give them properly sized supplies and a return path in the Manual D design for your Tequesta home.
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.
