Book air duct testing if you notice these signs in your Phoenix or Tempe home: – High electric bills – Rooms that never cool – Weak airflow at the vents – Uneven temperatures between rooms – A new HVAC system going in – Suspected attic leaks
Most leaks we find sit at attic trunk lines, return plenums, and poorly sealed branch connections.

Air duct testing cost in Phoenix depends on four things: square footage, how many HVAC systems the home runs, attic access, and whether sealing is needed after the test. A one-system home tests faster than a two-system home. You get the price in writing before any work starts.
Air duct testing takes about two hours on a normal Tempe house with one system. Homes with two systems run closer to three hours, because each system is pressurized and measured on its own. Sealing and a retest add time on the same visit when leaks turn up.
Yes. Air duct testing is worth running even when your AC cools fine, because leakage shows up on your power bill long before it shows up as discomfort. A system can hold temperature while losing a fifth of its air into the attic. The test tells you which one is happening.
A failed duct leakage test means your HVAC system is losing conditioned air before it reaches the living space. That raises energy bills, leaves rooms uneven, and makes the system run longer than it should. We seal the leaks with mastic and retest on the same visit to confirm the fix.
Yes. Air duct testing is required for most new HVAC installs in Arizona, and the result has to be filed before the job signs off. We run the test, record the CFM25 number, and file the report for your inspector.
