Attic Insulation & Duct Sealing

Upstairs 5–8 degrees hotter than downstairs? AC never shuts off? High summer bills? That's usually not 'just the AC.'

We tighten the attic, seal the ductwork, and stop throwing conditioned air into a 130° attic.

If this sounds familiar, it's probably the attic

  • • Bonus room or game room is always the hottest room in the house
  • • Master bedroom or upstairs stays warm at night even with the thermostat low
  • • AC runs nonstop in the afternoon and the bill is still high
  • • Dust and insulation fibers blowing out of ceiling vents
  • • Comfort changes room to room just walking down the hall

These are airflow and leakage problems, not 'just old equipment.'

Why this happens in North Texas attics

Supply ducts leaking cold air into a 130° attic instead of into the room

Return leaks pulling 130° attic air back into the system

Insulation that's thin, uneven, or tunneled through by past trades

Long duct runs to upstairs rooms that are undersized for the load

If the system is fighting the attic, it will lose. You feel that upstairs first.

We measure the loss before we quote the fix

  • Static pressure and airflow to the problem rooms
  • Duct leakage rate
  • Insulation depth and coverage
  • Attic temperature and delta T at the supply

What 'fixing the attic' usually looks like

  • Seal exposed seams and connections in supply and return ducts so you stop cooling the attic
  • Add/level blown insulation to bring coverage where it should be, not patchy piles
  • Correct or upsize runs feeding hot rooms
  • Air seal obvious penetrations so attic air stops dumping into living space

This is permanent work, not a portable fan in the hallway.

What it usually costs

Duct sealing: typically $1,500–$3,500
Attic insulation correction: typically $2,000–$6,000
Full attic performance package: typically $4,000–$10,000+

(air sealing + duct seal + insulation + airflow correction)

You see the outcome in actual room temperature, not in guesswork.

Common Questions

Can you fix just one hot room?

Often yes. Sometimes that room's duct run is undersized or leaking. Sometimes the insulation above just that room is trash.

Do I need a new AC to solve this?

Not always. Many homes waste cold air into the attic. Stopping the waste can stabilize temps without full system replacement.

Will this lower my bill?

Sealing duct leakage and air sealing the attic cuts energy waste. That means the system runs less to hold the same temperature.

Does this help resale?

Buyers in this area notice upstairs comfort first. A house that actually holds temp upstairs is easier to sell.

Your attic is bleeding comfort and money
