How We Work

Measured, Not Guessed

An equipment visit asks whether cold air is being made. We ask whether it arrives in every room.

Your AC makes the cold air

An HVAC service call checks this part. Usually it is fine.

Your attic and ducts decide how much survives

This is what we measure and fix.

LeaksAttic heatCrushed runsSmall returnsThin insulation

Your rooms get what is left

The hot room, the long runtime, the bill.

What Happens Next

Six steps. Tap one.

Before: a bare flex duct trunk in an Arizona attic During: the same trunk sealed and encapsulated in Insulated Duct Armor foam After: the protected ducts buried under blown-in attic insulation

Before. Bare duct in 140° attic air all day. What we often find, never what we leave.

Damien Mendez at Knights of the Attic did an awesome job balancing our cooling system after the attic portion of the work was complete. Listened to us and made adjustments based on our issues/ needs. Thank you!

Every single one of their employees was personable, polite, punctual, and tidy. We had experience with Nick, Antonio, Jovan, Miguel, and Noah.
Our house is significantly more comfortable. Our master suite is at the far end of the house and used to be 10 to 15° warmer than the rest of the home. We are sleeping so much better, thanks to Knights of the Attic! Highly recommend!

We have had a hot room upstairs since we moved in over a decade ago.  Numerous AC companies told us different things, no solutions.  These guys came out and fixed the airflow, sealed it up and everything is great now.  I wish I called sooner honestly.

    Why Your AC Can’t Keep Up During Arizona Summers
    If your AC runs all afternoon and the house never catches up, the equipment is often not the problem. The return side of your duct system may be starving it for air.

    How to Insulate Your Air Ducts
    Sealing first, then insulation over the outside, then out of the attic air wherever the attic allows. Why the usual wrap falls short, and what we do instead.
