Heating and air conditioning in many areas of the country place a greater emphasis on cooling because of their warm climates, but the need for an efficient ductwork system in your home is the same no matter the season. The ductwork is the series of large pipes that channels heated or cooled air from your furnace or air conditioner. Leaky HVAC ducts can account for substantial losses of conditioned air and wasted money every month. To keep your heating and air conditioning system working as efficiently as possible, it’s necessary to properly seal the ductwork in your home. You may have a significant leak in your ductwork if you’ve noticed one or more of the following symptoms:
Unexpectedly high heating or cooling bills Inconsistent heating or cooling, or rooms with unusual conditions such as:
Stuffiness or large amounts of airborne dust and particulates
Difficulty maintaining consistent and appropriate levels of heating or cooling in particular rooms or areas of the house
Ducts that are visibly damaged, loose, detached or missing
Un-insulated or poorly insulated ducts in unconditioned areas of your home, such as crawl spaces, unfinished basements and attics or garages
Leaky ductwork can also be dangerous if carbon monoxide or other harmful exhaust gases escape into your home. That’s why it’s important to have your system assessed regularly by a licensed heating and air conditioning professional in your area.
A ductwork sealing project should include the following:
Check the entire length of the ductwork system for potential leaks or other problems.
Repair or replace any damaged ductwork sections.
Reconnect loose sections and make sure they fit together tightly.
Straighten out any bent or kinked ducts.
Seal holes, cracks or openings in the ductwork.
Ensure secure duct connections at all registers and vents and at the HVAC unit.
Make sure all connections and joints are sealed with mastic which is a specialized sealant for use on ducts, or with metal tape.
Avoid using standard duct tape as the adhesive can fail over time. Insulate ductwork with rigid fiber board or the standard roll insulation.- This helps prevent energy loss through the metal of the ductwork itself.
