Our Certified Professionals Find Hidden Duct Leaks And Provide Duct Cleaning And Sealing

Ductwork is a vital part of your HVAC system. It provides a path for cooled or heated air to reach each room and a return flow for your AC/heater to repeat the process. However, a duct leak can reduce efficiency and have other unwanted effects. These can include higher energy bills, reduced comfort, and problems with indoor air quality (IAQ).

The trained and licensed HVAC professionals at Waldrop are experts in leak detection. They also provide high-quality IAQ services in Greenville and Spartanburg Counties. Every solution we deliver resolves leakage permanently, along with the comfort and IAQ concerns it can cause.

Duct Leak Testing

If there’s a duct leaking in your home, you may notice temperature fluctuations from room to room, increased dust, moldy odors from vents, pest infestations, and odd noises. You may also experience increased allergy and respiratory symptoms. When any of these occur, Y’all Call Wally to perform duct leak testing.

A visual inspection of ductwork can help spot holes, tears, gaps between connections, or patches for previous leaks. If you can feel air movement at a duct joint when the HVAC unit is on, there is a leak. An HVAC technician uses a more sophisticated process. It involves sealing all vents except one, sending pressurized air through your ductwork, and measuring the pressure at the unsealed vent; a pressure drop means a leak is present.
