Air Duct Services, VA

Your HVAC system is only as clean and efficient as its individual components. The air ducts in our homes are often overlooked, but they play a major role in system efficiency.

Air ducts are responsible for transporting heated or cooled air throughout your home. Dirty, clogged air ducts can greatly impede the efficiency of your HVAC system, and it can impact the quality of the air you breathe.

Air duct leaks can lead to higher utility costs and unnecessary wear and tear on your unit. When heated or cooled air escapes into unused spaces, such as the attic, your system will need to work harder to reach your desired temperature settings. Our HVAC experts can evaluate your ductwork and recommend the best course of action, with solutions like duct sealing and disinfectant fogging to clear ductwork of issues like mold growth.

The Cardinal heating and cooling team offers professional air duct services, including air duct cleaningair duct sealing and repairs and air duct system replacements.
