Houston Weather and HVAC Load
In a normal year, Houston racks up 1,222 heating and 3,279 cooling degree days (NOAA 1991-2020 normals). Cooling carries most of the load, which is why compressors and condenser fan motors wear out faster here than in northern cities. Count on roughly 5 nights below 32°F and 109 afternoons past 90°F in a typical year.

Houston Housing Stock
Half the homes in Houston were built before 1981 (Census ACS median), so the typical house is about 45 years old. A lot of these homes are on their second or third system by now. The ductwork is usually original, and leaky joints are common. About 385,000 households here own their home, 42% of the occupied total. The median home value is $253,400, and median household income is $62,894. We use both figures to adjust labor and pricing for this page.
Between 2020 and 2025, NOAA's Storm Events Database logged 28 hail days and 44 days with damaging thunderstorm winds in Harris County. The largest hail reported was 2 inches across. Hail flattens the thin aluminum fins on condenser coils and cuts airflow. After a big storm, take a look at the outdoor unit; homeowners insurance often covers the damage. Harris County also had 9 tornado days in that period.

Plan on $330 to $750, with most jobs near $560. Equipment efficiency, house size and the condition of the ducts and wiring decide where your quote falls.
When is the best time to schedule air duct cleaning in Houston?
Between late fall and early spring. With 109 days over 90°F, Houston contractors are booked solid all summer, and off-season jobs are easier to schedule and negotiate.
Does duct cleaning lower energy bills?
Not by much. Sealing leaky ducts makes a much bigger difference to efficiency and comfort.
How often should ducts be cleaned?
There's no set schedule. The EPA recommends cleaning when there's visible mold, pests or a lot of debris, not on a routine basis.
