About Greenacres
Manual J Load Calculation & Manual D Duct Design in Greenacres, FL.
Many Greenacres homes are running air conditioners sized decades ago for a house that has since changed. A 1970s home in Indian Pines may now have impact windows, a new roof and an enclosed patio, while a newer home near Jog Road may have been fitted with a builder's best guess. Swift runs Manual J load calculations in-house for the systems and duct projects we install in Greenacres, sizing equipment to what each room actually needs. Inland humidity makes this especially important. Greenacres summers are long and muggy, and an oversized system cools quickly, shuts off and leaves moisture behind, which is why so many homes feel cool but clammy. A correctly sized system runs longer, steadier cycles and pulls more water out of the air. From the room-by-room loads, a Manual D duct design sizes every run so the back bedrooms get the air they need. Our target is every bedroom within 3°F of the thermostat.
About this service
Manual J Load Calculation & Manual D Duct Design in Greenacres
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 Greenacres.
For a Greenacres Manual J, we measure every room's floor area and ceiling height, record window sizes, directions and glass types, check attic insulation and duct location, and note upgrades like impact windows or a new roof. We also ask how the home is used, such as how many people live there and which rooms are occupied during the day. The result is a heat and humidity load for each room. Manual S then guides the equipment choice toward systems with the capacity the home needs and strong moisture removal, which matters in Greenacres' humid summers. Manual D sizes each supply and return, places returns so bedrooms aren't cut off when doors close and checks the total duct resistance against the blower's capability. Manual T helps choose registers that throw air across the room. We review the design with you before installation, in English or Spanish, and after the work we measure airflow to confirm your Greenacres system performs as designed.

Frequently asked questions
It might be, but constant running can also come from leaky ducts, low refrigerant or a dirty coil. A Manual J load calculation tells us what size your Greenacres home actually needs, and comparing that with your current system shows whether size is the problem or something else is stealing capacity.
Manual J calculates both the heat load and the moisture load for each room. Manual S then selects equipment that can handle both. In Greenacres, where summers are long and humid, a correctly sized system runs longer cycles and removes more moisture, so the house feels drier at the same thermostat setting.
Yes. Hablamos español. We can walk Greenacres homeowners through the load calculation, the duct design and the equipment options in Spanish, so everyone in the family understands why a certain size and layout were chosen before any work begins. Ask for a Spanish-speaking team member when you book your visit.
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.
