Ductwork is the delivery system for your air conditioning: the supply ducts that carry cold air to each room and the return path that brings house air back to the air handler. The equipment gets all the attention, but the ducts decide how much of that cooling actually reaches your bedrooms.
Why ductwork matters in South Florida
This is the most overlooked problem in our market. Around 85 percent of the homes we evaluate that were built or ducted in the R-22 era have duct systems sized wrong for a modern high-efficiency system. Today’s equipment moves air differently than the systems those ducts were designed around, so a brand-new unit attached to old, undersized ducts is strangled from its first day. Add Florida attics that hit 130 degrees, where every duct leak sucks in superheated air, and ducts routinely explain the hot room, the high bill, and the system that never seems to shut off.
Signs of a ductwork problem
- One or two rooms that never cool no matter what the thermostat says.
- Vents that whisper in the far rooms and blast near the air handler.
- High bills paired with a system that runs constantly.
- Dust that returns immediately after cleaning, a hint of return-side leaks.
What Kyzar checks
A duct evaluation is part of every replacement we quote, because installing new equipment on a bad duct system wastes the money you just spent. We measure static pressure, check sizing against the equipment’s airflow needs, and inspect for leaks and crushed runs, then show you what we found.
