Signs You Need Ductwork Help
Leaky ducts signs are easy to miss because the problem sits in the attic. Watch for these.
-
Rooms far from the unit stay hot: Back bedrooms and far corners get weak airflow when ducts leak or kink. If one room runs warmer than the rest all summer, the ducts are a likely cause.
-
A dusty house: Leaky return ducts pull attic and crawl space dust into the air stream. If you dust often and the filter turns gray fast, a duct leak may be pulling dust in.
-
High summer bills: Ducts in a hot Davis attic leak and lose cooled air before it reaches the room, so the AC runs longer to hit the set temperature and the bill climbs.
-
Flex duct lying flat in the attic: Flex duct that sags, kinks or lies flat cuts airflow to a room. Crushed or flattened runs are common in older Davis attics and need to be rehung or replaced.
-
Rattling vents: Rattles and flutters at the registers can mean loose boots, disconnected runs or too much air pushing through a duct that is too small.
-
A whistling register: A whistle usually means air is squeezing through a small gap or an undersized return. A static pressure reading shows whether the system is working too hard to move air.

Why Ductwork Problems Are Common in Davis
Davis attics bake in summer, so leaky ducts heat the air before it reaches the room. Most Davis homes carry original or patched ducts.
-
Hot attics: Attics can pass 130°F on 100 degree days, and ducts lose cooled air into that heat.
-
Older homes: More Davis homes were built in the 1970s (about 6,200) than in any other decade, plus about 3,400 in the 1960s.
-
Original ducts: Many homes from the 1960s to 1980s still run on original or patched ducts.
-
Long cooling seasons: An average summer reaches 100°F on 15 to 20 days, so weak ducts run hard.
-
Cottonwood and dust: Dust and fluff collect around returns and registers.
Duct Problems We Fix
Most duct trouble falls into a short list. These are the repairs we do most.
Leaky joints
Seams between sections lose air when tape or mastic fails, and we reseal them with mastic.
Crushed or kinked runs
Flex duct that was stepped on or bent gets rehung, straightened or replaced.
Disconnected boots
The boot connects the duct to the register, and a loose one dumps cooled air into the ceiling.
Undersized returns
A return that is too small makes the system work hard, and we add or enlarge returns where needed.
Uninsulated ducts
Bare ducts lose cooled air to the attic, so we wrap or replace them with R8 insulated duct.
Sagging runs
Ducts that hang between joists get new straps and supports.
