Call (737) 378-9016Duct cleaning is one of the most oversold services in home repair, so it is worth knowing when it actually helps. The U.S. Environmental Protection Agency's guidance is that routine duct cleaning has not been shown to prevent health problems, but that cleaning makes sense in specific situations:
Mold growing inside ducts or on other parts of the system, confirmed by looking, not just a smell.
Rodents or insects living in the ductwork.
Enough dust and debris that it blows out of the supply registers.
A remodel or new build where drywall dust and sawdust got into the system.

A very low advertised price for whole-house duct cleaning is a common bait. The crew arrives, finds a problem, and the price climbs. Ask before anyone comes out:
Cedar pollen from December into February, spring oak pollen, and construction dust from a city that never stops building all end up in Austin filters. A good filter, changed often, keeps most of it out of the ducts in the first place. If dust keeps coming back quickly, leaky return ducts pulling in attic air are often the real problem, and sealing them does more than cleaning.

Austin Energy has offered rebates for duct sealing in some of its programs; see Austin Energy rebates. Call and you will be put through to a licensed local HVAC company that can look at the ducts and tell you whether cleaning, sealing or neither is worth it.
There is no set schedule. Cleaning is worth it for visible mold, pests, heavy debris or after construction. Otherwise, good filters changed regularly usually do more.
The EPA says routine duct cleaning has not been shown to prevent health problems. Better filtration and sealing leaky returns usually help more.
Be cautious. Very low advertised prices are a common way to get a crew in the door before the price rises. Ask for a written total first.
In attic systems, leaky ducts are often the bigger problem. Sealing them keeps hot, dusty attic air out of the system.
