Air Duct Service American Standard Greenville

At Eastergard HVAC, we understand that the efficiency and performance of your HVAC system depend heavily on the condition of your air ducts. Our comprehensive air duct services, including air duct sealing, insulation, and testing, are designed to optimize your system's operation and enhance your home's comfort. Leaky ducts can lead to significant energy loss and inconsistent temperatures throughout your home. Our professional air duct sealing services ensure that every joint and seam in your ductwork is properly sealed, preventing air leaks and maximizing the efficiency of your heating and cooling system.



In addition to sealing, we offer air duct insulation services to further improve your system's efficiency. Proper insulation helps maintain the temperature of the air as it travels through your ducts, reducing energy loss and ensuring that your HVAC system doesn't have to work as hard to keep your home comfortable. Our air duct testing services utilize advanced equipment to detect any issues with airflow or pressure within your duct system, allowing us to identify and address problems before they escalate. By choosing Eastergard HVAC for your air duct needs, you're investing in the longevity and performance of your HVAC system, as well as the overall comfort and air quality of your home.

Air Duct Services

According to the U.S. Department of Energy’s Energy Star program, leaky ducts in attics or crawlspaces can account for 20 percent or more of a home's heating and cooling energy losses. This results in higher utility bills for you and difficulty keeping your house comfortable.


A few signs you may have leaky ducts are if you have:

  • High utility bills in summer and winter
  • Difficult-to-heat-and-cool rooms
  • Stuffy rooms that never seem to feel comfortable
  • Attic, crawlspace, or garage ducts
  • Tangled or kinked flexible ducts in your system

What Can You Do About Leaky Ducts?

Run your system, and check all the ducts and joints you can access. You can seal these yourself with mastic or foil-backed tape. You should also seal around where the duct meets the wall. Duct tape is actually not recommended for ductwork, and any fabric-backed tape will deteriorate over time. If you have questions about appropriate tape call us at 864-235-2935 or talk to a representative at your local hardware store.

Heating & Air Conditioning FAQs

  • What Does HVAC Stand For?

    HVAC stands for Heating, Ventilation, and Air Conditioning. It encompasses the systems used for moving air between indoor and outdoor areas, along with heating and cooling residential and commercial buildings. These systems keep you warm in the winter and cool in the summer while ensuring indoor air quality.

  • How Often Should I Have My HVAC System Serviced?

    It’s recommended to have your HVAC system serviced twice a year: once before the cooling season (spring) and once before the heating season (fall). Regular maintenance helps prevent breakdowns, improves efficiency, and extends the lifespan of your system.

  • How Can I Improve My HVAC System's Efficiency?

    Improving efficiency can be achieved through regular maintenance, such as cleaning or replacing air filters, sealing duct leaks, ensuring proper insulation, and upgrading to a programmable thermostat. Additionally, scheduling professional tune-ups and considering energy-efficient system upgrades can significantly enhance performance.

  • What Does HVAC Maintenance Include?

    HVAC maintenance typically includes inspecting and cleaning coils, checking refrigerant levels, inspecting and tightening electrical connections, lubricating moving parts, checking thermostat settings, and ensuring the system is operating correctly. Regular maintenance helps prevent breakdowns and ensures efficient operation.

  • Why is Regular HVAC Maintenance Important?

    Regular maintenance improves system efficiency, extends the lifespan of your equipment, helps prevent costly breakdowns, and ensures optimal performance. It also improves indoor air quality and can lower energy bills by keeping the system running efficiently.

  • When Should I Replace My HVAC System?

    Consider replacing your system if it’s over 15-20 years old, requires frequent repairs, is no longer efficient, or if you’ve noticed a significant increase in energy bills. Newer systems are more energy-efficient and can provide better comfort and cost savings.
