More homeowners are getting serious about saving energy with practical devices and upgrades, such as installing programmable thermostats and sealing air leaks around windows and doors. Find out how duct sealing can play a vital role in your energy-efficiency strategy, so you can better enjoy cooling comfort this summer and years after.
The air ducts are responsible for channeling cooled and heated airflow from the A/C and furnace to the living spaces of your Mid-Atlantic home. If the ducts are loose, leaking air, uninsulated or are of poor design, you’ll have higher energy bills and declining comfort.
Plug the Air Leaks
Duct sealing and insulation can boost A/C and furnace efficiency in the typical home by more than 20 percent. That’s a substantial amount of energy savings and less wear on the HVAC system. Look for these telltale signs that ailing ducts are in your home:
- You hear rattling and clamoring from the outlets.
- You see dirt streaks at duct seams.
- There are hot or cold spots room to room.
- Airflow is unequal from the outlets.
- You have high energy bills.
Loose and leaky duct connections and joints should be sealed with metal tape and a gooey paste sealant called mastic. Some ducts may be inaccessible or in inhospitable locations, like the attic, basement or crawl space. If you or other household member are going to venture into these areas, make sure to wear proper safety gear, or seek the assistance of an HVAC professional if you have concerns or questions.
Cover Your Energy Losses
Duct sealing should be followed by insulation to prevent heat gain/loss through thin metal duct walls. During the duct leak inspection, note any ducts in the attic or other unconditioned spaces that don’t have insulation. These ducts must be insulated. Common insulation for air ducts are fiberglass rolls, rigid fiber board (which are available to help dampen noise) or blown-in foam insulation.
