Does duct cleaning help indoor air quality?
It can help when ducts contain heavy dust, construction debris, or visible buildup. Filter quality, sealing, and system maintenance also matter.
Can ductwork cause rooms to be too hot or too cold?
Yes. Poor duct sizing, leaks, restrictions, or unbalanced airflow can create uneven comfort even when the equipment is working.
Do you install new ductwork?
Yes. ChillTech installs and improves residential ductwork for forced-air heating and cooling systems.
