Stop Paying to Cool Your The Colony Attic

Most of the duct in a The Colony home runs through the attic, where summer temperatures climb past 140 degrees. When that duct leaks, sags, or pulls apart at the joints, the cold air you paid for never reaches the rooms, and you end up cooling the attic instead. After 20-plus years, the original flex duct in a lot of homes here is doing exactly that. We seal the leaks with mastic, re-support the runs, and balance the airflow so your house actually gets comfortable. Leaky ducts also pull dust and attic air into your system, so it is worth pairing this with indoor air quality work in The Colony, and an annual AC tune-up keeps the whole system pulling its weight.

What's Going Wrong in The Colony Ductwork

Attic Heat Gain on Long Runs

In a The Colony summer, an unconditioned attic can hit 130-150 degrees. Air moving through leaky ducts up there picks up heat and loses cooling before it ever reaches the room

We seal the connections and add insulation so the cold air you paid for actually makes it to the vents

Aging Flex Duct Pulling Apart

Many homes here from the late 1990s and 2000s have flex duct that has sagged, crushed, or pulled loose at the boots and plenums after 20-plus years

We re-support sagging runs, reconnect blown-off boots, and seal every joint with mastic instead of cheap tape

Hot and Cold Rooms

One room never cools while another freezes, usually a sign of leaks, crushed duct, or rooms starved of airflow

We measure static pressure and airflow, then seal and balance so every room gets its fair share

Money Leaking Out the Ducts

Typical homes lose 20-30% of conditioned air to duct leaks, which on a hot The Colony bill is real money every month

Sealing the system keeps that air in the house and drops your runtime, paying you back through the summer
