Experts in Flexible & Sheet Metal Air Duct Leakage Testing, Sealing, and Improvements

Your ductwork system is an often overlooked part of your HVAC system, but it's arguably one of its most important components. If your ducts are poorly designed or leaking through holes, loose connections, and old insulation, you could experience unbalanced heating and cooling throughout your home, notice more dust and pollutants in your home, and lose as much as 20% of your system's energy efficiency. This loss of heating and cooling efficiency means that you'll need to use more energy and make your system work harder to get the level of indoor comfort you prefer. As a result, you pay higher energy bills each month, create more air pollution, and shorten the lifespan of your HVAC equipment.

Preparing Ductwork for Your New Heating & Air Conditioning System

If you are planning to invest in a new heating and/or air conditioning system, one of our NATE-certified HVAC technicians can inspect your ducting system to ensure that it can effectively meet your needs. We identify the type of ductwork you have (usually flexible fiberglass or asbestos), check its condition, look for obvious leaks, assess the design, and discuss your heating and cooling preferences. If you have asbestos ductwork that needs to be removed, we'll have a licensed abatement company safely remove the asbestos before we begin. Manufacturing the new HVAC system itself can take up to two or three days, since it involves carefully installing all equipment, condensers, cooling coils, dampers, ductwork, supply registers, adjustable dampers, filtration systems, and more until they all come together as a singular system custom designed for your home and specific needs.
