Guaranteed Results

Airflow Guarantee

What It Is:
We guarantee your system will deliver the correct amount of airflow to every room according to design. Using professional air balancing equipment (flow hoods, manometers, dampers), we test and fine-tune airflow until it matches target performance.

Why It Matters:
Airflow is the foundation of comfort. Without balanced airflow, no amount of insulation or sealing will solve hot and cold spots.

How We Prove It:

• Room-by-room airflow is measured in cubic feet per minute (CFM).
• We take room-by-room heat load calculations to ensure each room gets the proper amount of air.
• Targets are compared to ACCA design standards.
• You receive a before-and-after airflow report.

How It Affects You:

• If airflow falls short in the future, we come back and correct it free of charge.
• Consistent comfort in every room, not just near the thermostat.
• No more “that one room” that never feels right.

Comfort Guarantee

What It Is:
Comfort means different things at different levels of protection:

• Silver & Gold Packages: We guarantee consistent comfort with doors open.

Why It Matters:
Most homes suffer from pressure imbalances — close a bedroom door, and suddenly airflow drops. We eliminate that.

How We Prove It:

• Room pressure measured in Pascals before and after.
• Comfort verified during final walkthrough with homeowners.

How It Affects You:

• Privacy no longer means sacrificing comfort.
• Even comfort whether doors are open or closed.
• Family members stop fighting over “the hot room” or “the cold room.”

Energy Savings Guarantee

What It Is:
We guarantee your system will use less energy after our improvements by eliminating leaks, sealing ducts, and reducing attic heat gain.

Why It Matters:
Heating and cooling can make up 40–50% of your utility bill. Wasting that energy into the attic is like throwing money away.

How We Prove It:

• Measure duct leakage reduction (often 80–90% improvement).
• Document efficiency gains through runtime data and utility comparisons.

How It Affects You:

• Confidence that your comfort upgrades also make financial sense.
• Lower monthly bills, especially during peak Arizona summers.
• Savings that often pay back your investment over time.

Air Temperature Guarantee

What It Is:
We guarantee that air coming from your supply vents will be colder in summer and warmer in winter after our upgrades.

• Silver: Suspended ducts cocooned in Insulated Duct Armor deliver colder temps.
• Gold: Buried ducts retain maximum cold, delivering the coldest possible air.

Why It Matters:
Leaky, uninsulated ducts often lose 5–10°F before air even reaches your vents. That’s wasted comfort and wasted energy.

How We Prove It:

• Temperature probes measure supply air before and after upgrades.
• Average reduction in air temperature loss: 6–9°F improvement.

How It Affects You:

• Shorter runtimes reduce strain and save money.
• Colder, more refreshing air at every vent.
• Rooms reach setpoint faster and stay comfortable longer.

100% Money-Back Guarantee

What It Is:
If we can’t deliver the improvements promised — airflow, comfort, efficiency, or temperature — we’ll make it right or refund your investment.

Why It Matters:
Most contractors say “no refunds.” We remove that risk entirely.

How We Prove It:

• All performance results are documented before and after.
• If targets aren’t met, you don’t pay.

How It Affects You:

• Peace of mind knowing you’ll either get the results or your money back.
• Zero risk in choosing Knights of the Attic.
