Duct leakage can have a detrimental impact on your indoor air quality. It has also led to cooling and heating system issues in homes throughout the Greenville and Spartanburg area. Over time, air pressure, thermal expansion and contraction, mechanical stress, corrosion, and contamination can lead to issues that cause air leaks. These may come from small holes, poor connections, or tears in your ductwork. Fortunately, our team is trained and equipped to assess the problem and provide an effective solution to duct leakage.

Waldrop provides professional duct sealing services to restore indoor air quality and HVAC efficiency. Y’all Call Wally  today to schedule an appointment.

Sign That It’s Time For Air Duct Sealing

Your home may be telling you there are hidden duct leaks. To correct them, we use non-invasive methods like Aeroseal that avoid breaking through walls or floors to patch peaks in less accessible areas. Y’all Call Wally if you notice any of the following:

  • Increased Energy Bills: A leaky duct can lose up to 30% of the conditioned air in your home. To compensate, your HVAC unit will use more energy.

  • Odors: The air blowing from AC vents may smell stale or musty. The scent is caused by air entering through gaps from crawlspaces, attics, or spaces between walls.

  • Noises: If you hear pinging, rattling, or other unusual sounds from ducts, your ductwork may be damaged and potentially have an air leak.

  • Low Air Flow: So much air may leak that there’s not enough left when it reaches a vent; therefore, it may seem like your AC is hardly blowing.

  • Reduced Comfort/Air Quality: The AC may be unable to provide adequate cooling. Your home may also be dustier and stuffier than usual and fill up with particulates from outside.

How We Seal Air Ducts

When you need duct sealing, Y’all Call Wally. A skilled contractor will use dedicated testing equipment to locate and assess the leak. They will restore the airtightness of your ductwork by using mastic or metallic taps. Leaky ducts can also be sealed from the inside with Aeroseal. The sealing material is sent into your ductwork and naturally binds to small gaps and poor connections in areas that are difficult to access, stopping air from escaping. 

Additional Duct Services

  • Air Duct Cleaning: Dirty ductwork can affect your cooling and heating system and your indoor air quality. Our professionals are licensed and trained to use the latest equipment and techniques to clean and sanitize your ducts and eliminate sources of contamination.

  • Air Duct Replacement: If your air ducts are physically damaged or poorly designed in the first place, we’ll recommend replacing them. Aging ducts can affect the reliability and efficiency of your HVAC system. Duct replacement can be a cost-effective solution in the long run.

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!!!!!!!!)
