Comfort complaints usually start in the ducts, not the equipment. These five signs come up again and again.
- One room that never keeps up, in any season.
- Dust that comes back within days of cleaning.
- The system running almost constantly on mild days.
- Visible flex duct that is crushed, kinked or sagging.
- A whistling or roaring return when the fan starts.
Each of them shows up as static pressure outside the manufacturer’s range, which is the number we measure first. Fix the duct and the equipment finally gets to do its job.
