Start with the decision you need to make

Use this air duct cleaning guide to separate the homeowner question, the evidence available, and the next professional step without guessing at unsupported details.

Build a useful decision record

  • Write down the current system or comfort context.
  • Separate observations from assumptions about the cause.
  • Keep professional findings and written estimates together.
  • Use the same questions when comparing next-step options.

Use official evidence for equipment facts

ComfortGauge uses the approved research packet to support equipment facts while keeping its own decision methodology separate from those factual sources.

What the reviewed evidence adds

  • Heating and cooling guidance: ENERGY STAR heating and cooling guidance includes filter care, system maintenance, duct sealing, replacement decisions, and proper installation.
  • Duct-cleaning context: EPA does not broadly recommend routine duct cleaning and emphasizes correcting underlying moisture or contamination causes when they are present.
  • Indoor-air-quality context: EPA indoor-air guidance emphasizes source control, ventilation, filtration, and building-system maintenance as broad indoor-air-quality factors.

Information to keep for the next step

  • The exact question or symptom that started the decision.
  • Recent maintenance or repair history.
  • Professional findings or written estimates already received.
  • The outcome you want to improve, such as comfort, reliability, or planning clarity.

Use ComfortGauge to choose the next step

ComfortGauge separates low-risk observations, professional inspection triggers, and longer-term decision support. Use the linked tools and guides to organize the next step rather than treating this page as a substitute for an on-site diagnosis.
