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.

Additional Duct Services

Aside from finding duct leakage, Waldrop takes any necessary steps to improve your ductwork. Our technicians use the latest tools and methods to provide:

  • Air Duct Cleaning: Air duct cleaning isn’t required or recommended regularly, but it can help reduce air pollution in your home. Cleaning HVAC ducts can eliminate dust, pollen, mold, bacteria, pesticides, and volatile organic compounds. It can also eliminate odors from tobacco smoke, cleaning products, paint fumes, and organic sources. Duct cleaning can also reduce wear and tear on your HVAC system so that you may save on improved efficiency, fewer repairs, and a longer system lifespan.

  • Air Duct Sealing: Duct leak testing allows our technicians to determine if you need air duct sealing. Duct leakage can reduce airflow, introduce musty odors from unconditioned spaces, and reduce comfort. To resolve these issues, we can seal leaks from the outside with metallic tape, or use Aeroseal, which is a material blown into ductwork to seal small gaps and poor connections from the inside. It stops air from escaping without having to physically access hard-to-reach areas.

Noah S. Dan & Hayden are the absolute BEST!!!! Noah came and checked my septic tank and told me it needed to be pumped. He answered my many questions with great knowledge about different options available to me. This was on Friday after 4p.m. He quickly called Dan and Hayden to see if they could do one more. Otherwise, I would have been without a bathroom until Monday. The professionalism in which each handled their job was impressive not to mention the kindness shown to a senior adult. They should be labeled the A-TEAM (AND Given a raise!!!!!!!!)
