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.

Gavin and Aiden came to replace a toilet but discovered a clogged drain, then a pump that didn’t work and finally they replaced a faulty outlet that ran the pump. They went the extra 5 th mile to really solve the problem. They were both very professional and just terrific, hard workers who really care about their work. Waldrop is lucky to have them both!

Milton was very professional in his efforts to help me locate a water leak in my bathroom. Unfortunately we will have to do more research to find the problem but can’t blame him.

Paris, John and Lorenzo came out today and installed a split unit at my house. It was an easy process. The only noise was drilling all the holes in the house they needed. They were done at exactly the time they approximated. The area was cleaner than when they started. Extremely knowledgeable and friendly. Would definitely recommend them to anyone who needs a hvac system installed.
