About Port St. Lucie
Airflow Diagnostic & Duct Balancing Assessment in Port St. Lucie, FL.
Port St. Lucie homeowners often tell us their AC is fairly new but the house still isn't comfortable. That's usually because the equipment was replaced and the ducts weren't. In the boom-era homes of St. Lucie West, Torino and the western neighborhoods, builder-grade duct layouts send plenty of air to the rooms near the air handler and too little to the bedrooms at the back. In two-story homes, the upstairs runs warm in the afternoon. In older east-side homes, decades of patches have left some runs leaking or disconnected. Humidity makes the weak rooms feel worse. Our Airflow Diagnostic and Duct Balancing Assessment puts numbers on the airflow each room is receiving. It's a paid diagnostic, and we tell you the fee when you schedule. The readings show whether balancing, return-air fixes and sealing will even out your Port St. Lucie home or whether some runs need to be rebuilt.

About this service
Airflow Diagnostic & Duct Balancing Assessment in Port St. Lucie
If some rooms in your home are always warmer or colder than others, the problem usually isn't the size of your air conditioner. It's how the air moves through your ducts. Long or undersized runs, crushed flex, leaky joints, missing returns and dampers set by guesswork all keep air from reaching the rooms that need it. Replacing the AC or adding a smart thermostat rarely fixes that, and closing vents in other rooms often makes it worse.
Swift's Residential Airflow Diagnostic and Duct Balancing Assessment measures what your system is actually doing. We read total external static pressure with a manometer and compare it with your air handler's rated limit. We measure airflow at every supply register with a flow hood or anemometer and compare each room with what its load requires. We run a duct leakage test that pressurizes the duct system to find out how much air escapes before it reaches your rooms. And we take room-by-room temperature readings and scan ceilings, walls and duct runs with a thermal camera.
Then we balance the system: adjusting dampers, correcting register sizes and styles, adding transfer grilles or jumper ducts so closed bedrooms have a return path, and sealing the leaks we can reach. Our target is the same one we design to on new installations, every bedroom within 3°F of the thermostat, consistent with ACCA's Manual RS comfort guidelines.
You get a clear explanation of every reading and of what we changed. If something bigger is needed, such as a new return, duct repairs or a full duct replacement designed with Manual J and Manual D, we'll show you the numbers that support it and give you a price before any further work. The assessment is a paid diagnostic visit, and we quote the fee when you book. Call (561) 685-8408 to schedule.

Local details
Airflow Diagnostic & Duct Balancing Assessment details for Port St. Lucie.
We begin with total external static pressure, read with a manometer and compared with the air handler's maximum. Many Port St. Lucie homes with newer, higher-efficiency equipment show high readings because the original ducts and return are too small for it. Then we measure airflow at every supply register with a flow hood or anemometer, room by room, and compare it with each room's load. The duct leakage test comes next: we pressurize the ductwork with a calibrated fan to see how much cooled air is slipping out into the attic. Room-by-room temperatures and a thermal camera scan show where heat gets in, where insulation is missing and which runs are disconnected. With those results, we balance the system by setting dampers, matching registers to their rooms, adding transfer grilles or jumper ducts for closed bedrooms and sealing reachable leaks. We go over the readings with you and leave a summary of what was adjusted and anything your Port St. Lucie home still needs, with prices for additional work.

Frequently asked questions
A new air conditioner connected to the old ducts delivers air the same uneven way. If the duct to that room is undersized, leaking or has no return path, the room stays warm no matter how new the equipment is. Our assessment measures that Port St. Lucie room's airflow and shows what will fix it.
Over time, yes. When the ducts or return are too small for the system, static pressure climbs, airflow drops and the blower works harder. That can reduce efficiency, raise noise and even freeze the coil. Measuring static pressure is the first step of our Port St. Lucie assessment.
Yes. We measure airflow at every register on both floors and compare each room with its load, which usually shows how much the upstairs is shortchanged. Then we balance the dampers to shift air upstairs and explain whether your Port St. Lucie home needs return or duct changes as well.
Four: total external static pressure measured with a manometer, airflow at every supply register measured with a flow hood or anemometer, a duct leakage test that pressurizes the duct system, and room-by-room temperature readings with a thermal camera scan. We then balance the system where we can and review the results with you.
It's a paid diagnostic visit. The fee depends on the size of your home and the number of systems, and we quote it when you book so there are no surprises. Any balancing adjustments we can make during the visit are included, and any further repairs are priced before we do them.
