Warranties & Guarantees Guaranteed results, backed in writing, from Phoenix duct & attic specialists

You choose the targets. We build the plan from your home's measurements. We put our name on the result.

Four guarantees, one warranty

Guarantees That Prove It, Not Just Promises.

Every number we quote is taken in your home before any work is proposed, and the plan is built from it. That is what lets us guarantee results instead of effort. Which guarantees go into your plan, and how big each target is, is decided with you.

  • Each guarantee has a target you choose, written into your plan
  • Each one is built from the measurements we take in your home
  • If a result falls short, what we do about it is written down too
(602) 675-6827

Free Duct & Attic Assessment, about 2 hours, with you present. We do not sell or service HVAC equipment.

Why we can do this and most can’t

A guarantee is only as good as the measurement behind it.

We measure every room, every vent, every door and the attic before anything is proposed. The guarantees are built from those measurements, with our name and your targets on them.

  • 4GuaranteesYou pick which ones, and the target for each
  • 1Warranty20 years on our labor, on every job
  • 1AssessmentEvery reading taken before a dollar is spent
  • 100%Money-BackIf a promised result falls short, we make it right or refund it

Your Assessment Report

The Plan Isn’t Guessed. It’s Built From Your Numbers.

This is what an assessment report looks like. Watch the Target column land, one line at a time, and the guarantee each target feeds light up. Plans that include the written report carry your rooms and your readings.

Sample assessment report in four sections: room-by-room airflow as found and the target set for each, the system, the attic, and the guarantees written into the plan. Sample values are illustrative.

A · Room by room

How much air reaches each room, against what the room needs.

Measured at every vent before anything is proposed. The master bedroom was getting about half of what it needed. That is the room that never cooled. The plan’s target is nearly all of it.

B · The system

How much cooling the ducts lose on the way, and whether a closed door starves the room.

Leakage is tested on the whole duct system, the air temperature is read at the vent, and room pressure is tested with the door closed. The plan’s targets: air 8° colder at the vent, and a bedroom that no longer pushes its air into the attic.

C · The attic

How much heat the attic pushes into the house, and how much of it the ducts have to fight.

Insulation depth at twelve points, the wall tops where attic air gets in, and every duct rated by condition. The plan: the attic sealed and covered, and the ducts protected or replaced.

D · Written in

Every guarantee in the plan, sized from the readings, with you in the room.

The guarantees themselves are written into your plan: each target you chose, the reading it was sized from, and your signature next to ours. If a result falls short, tell us and we make it right, and the 100% Money-Back Guarantee stands behind the rest.

Every as-found line is a measurement you watched us take. Sample values are illustrative; when your plan includes the written report, it carries your rooms, your readings and your photos.

The Four Guarantees

Each Guarantee Has a Target You Choose, Built From Your Home’s Numbers.

Pick one, several or all four. Each one is written into your plan with its target, built from your assessment, and backed by the full terms below. Tap a target to see how the guarantee reads for you.

  • Guarantee 1 of 4

    Comfort Guarantee · Room or Whole-Home

    “The rooms in your plan hold a consistent, comfortable temperature with the thermostat at its normal setting, doors open or closed.”

    Your target: which rooms?

    What the guarantee says

    We guarantee the room(s), system or your entire home as described nearby will remain within 3°F of the thermostat set point, every day of the year measured in the center of the room 4 feet above the floor.

    Described in your plan as: the one or two rooms you called about (Room Comfort)

    • If it falls short

      We return to revise and/or rebalance your system at no cost to you.

    • How long

      1 year from the date your project is completed.

    • What the terms measure

      Room temperature against the thermostat set point, in the center of the room 4 feet above the floor. If a room falls short, tell us and we make it right.

    Full terms: prerequisites and exclusions
  • Guarantee 2 of 4

    Energy Savings Guarantee

    “Your HVAC system uses less energy after our improvements, by the amount you choose.”

    Your target: how much lower should your HVAC utility costs be?

    What the guarantee says

    We guarantee your energy savings, calculated as your HVAC utility costs (electric plus gas if an AC/furnace system or electric only if a heat pump system) for (a) the 12-month period prior to our installation, less (b) the 12-month period following our installation (i.e. your “energy savings”) will equal or exceed the projected energy savings provided below.

    Projected energy savings in your plan: 30%

    • If it falls short

      We pay double the difference between your actual energy savings and the 30% projected in your plan.

    • How long

      Through one month after the utility bill that completes the 12 months following our installation.

    • What the terms measure

      Your HVAC utility costs for the 12 months before our work against the 12 months after it, as the terms describe. If the savings fall short, we pay double the difference.

    Full terms: prerequisites and exclusions
  • Guarantee 3 of 4

    Set-Point Holdfast Guarantee

    “Your home holds its thermostat set point when the outdoor temperature reaches the level you choose.”

    Your target: the set point your home should hold

    Your target: up to what outdoor temperature?

    What the guarantee says

    We guarantee your home will be able to achieve an internal temperature at the thermostat set point defined below, up to the external temperature defined below, measured at the thermostat location.

    Defined in your plan as: 76° inside, up to 110° outside

    • If it falls short

      We return to revise your system at no cost to you.

    • How long

      1 year from the date your project is completed.

    • What the terms measure

      Indoor temperature at the thermostat against the set point, on days up to the outdoor temperature you chose. The plan is built to that load: duct protection, attic insulation and sealing, airflow.

    Full terms: prerequisites
  • Guarantee 4 of 4

    100% Money-Back Guarantee

    “If we can’t deliver the improvement your plan promises, in comfort, energy savings, or set-point holdfast, we make it right or refund your investment.”

    Your target: nothing extra to choose

    What the guarantee says

    If we are unable to satisfy the terms of any of the guarantees included with your purchase and make it right, we will give you your money back.

    Covers: every guarantee you chose above

    • If it falls short

      The full purchase price refunded to you.

    • How long

      1 year from the date your project is completed.

    • What it needs from you

      The prerequisites of your guarantees met, and the chance to make it right first, including access to your home for any extra work or testing.

    Full terms: prerequisites

Honest limits

The guarantee is the target in your plan, measured the way the terms describe.

Typical results we quote elsewhere, such as leakage cut by 80 to 90 percent or air 6 to 9 degrees colder at the vent, are typical results from our jobs, not promises for yours. Your promise is the target written into your plan. We don’t sell or service HVAC equipment, so the equipment itself is not covered, and each guarantee’s terms say what has to be in place for it to apply.

What you keep

Your targets in writing, the photos, and a phone number that answers.

Your assessment report with every reading, the photos and thermal images, your targets and their terms in writing, the 20-year labor workmanship warranty on file. If a number drifts years from now, the assessment report is the baseline we come back to.

Also on Every Job

20-Year Labor Workmanship Limited Warranty

The guarantees are about the result. The warranty is about the work: if a problem ever arises from our workmanship, the labor to fix it is covered, for twenty years.

  • 20 yearsFrom the date of installationDefects in workmanship on all installation work we provided.
  • $0Repair or replace, at no cost to youAny component or installation found defective due to workmanship.
  • TransfersTo the next owner if you sellThe new owner lets us know in writing within 30 days of the sale.
  • 30 daysTo tell us after you notice a defectThen we inspect the work, confirm it, and fix it.

Separate from the four guarantees, which are about the result you chose. The warranty covers the quality of the work itself, on every job, whichever guarantees are in your plan.

Questions

Warranties and Guarantees, Answered

Do I have to take all four guarantees?
No. Which guarantees go into your plan, and how big each target is, is decided with you. A plan can carry one, several or all of them. The 100% Money-Back Guarantee stands behind whichever ones you choose.
Who sets the targets?
You do, from the assessment’s findings. Which rooms, how much lower your HVAC energy costs should be, what set point your home should hold and up to what outdoor temperature. Each target is written into your plan, and the plan is built to it.
What happens if a result falls short?
Each guarantee says exactly what we do. Comfort and Set-Point Holdfast: we return and revise or rebalance your system at no cost to you. Energy Savings: we pay double the difference between your actual savings and the savings projected in your plan. If we still can’t make it right, the 100% Money-Back Guarantee refunds the full purchase price.
How are energy savings measured without promising a dollar figure?
By the HVAC share of your utility costs, as the terms describe: the 12 months before our work against the 12 months after it, as a percentage you chose from 10% to 60%. Typical ranges we quote elsewhere are typical, not your promise; your promise is the percentage in your plan.
Is my air conditioner or furnace covered?
No. We don’t sell or service HVAC equipment, so the equipment itself is not covered, and each guarantee’s terms list what has to be in place for it to apply, including equipment that performs the way its manufacturer says it should. If your equipment needs work, we tell you, and we tell you what the ducts and attic need so the equipment has a chance.
Does the warranty transfer if I sell my home?
Yes. The 20-year labor workmanship warranty transfers to the new owner when they let us know in writing within 30 days of the sale, with proof of the sale and their contact details. The full warranty text is on this page.
What do I actually have in hand when the job is done?
Your plan with your targets and their terms in writing, the photos of the finished work, and the warranty on file. When your plan includes the written assessment report, you keep every reading and thermal image too, and when it includes verification testing, the after-readings sit beside the as-found ones. Either way, the measurements we took are the baseline we come back to if a number drifts years from now.

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.
