Cost of duct cleaning in San Marcos, TX
Factors that affect the cost of duct cleaning:
- The number of return drops: The more return drops you have, the higher the cost of the duct cleaning will be. A return drop is part of your home's ductwork. It guides air from your home to your HVAC system, where the air will be heated/cooled. The air that passes through the return drop usually carries a lot of dust, which means the return drop itself can get really dirty.
- The number of HVAC units you have: If you have more than one HVAC system, then duct cleaning will be more expensive because you will have more ductwork that needs cleaning.
- The nature of the contaminants: If your ducts have contaminants like mold or pests, then the cost of duct cleaning will be greater.
Signs you need duct cleaning
According to the EPA, you may need duct cleaning if...
- You see visible mold growth in your ducts

"I highly recommend this company to anyone who asks"
"Alan was amazing to work with and he was here in less than an hour of our call after hours in the rain! He gave us a diagnostic of our system, a quote on a repair and for a new system so we had options. It was nice to have a service tech who was up front and honest with us and didn't treat us like a number or a paycheck. He worked with us, answered all of our questions, and I highly recommend this company to anyone who asks."
