Sealing Ducts Can Boost Home Comfort and A/C Efficiency
- May 12, 2014
No one wants to be uncomfortable in their own home when warm weather sets in. However, that’s often the case in the typical home with leaky ducts. Do a little research into sealing ducts this spring, and you may rest and relax in cool comfort this summer with better air conditioning efficiency.
Telltale Signs of Leaky Ducts
The air ducts are responsible for channeling conditioned airflow to all the rooms of the home. When the ducts are leaky, as they are in the typical home, you experience discomforts and higher energy bills. Watch for these signs of leaky ducts:
- Noises – Air leaks are largely caused by loose ducts, and loose ducts rattle and clamor.
- Uneven temperatures – Drafts and hot and cold spots from room to room are indicators of duct leaks.
- Unbalanced airflow – When there are leaks in the air ducts, airflow is often unbalanced from the supply outlets.
If you noticed any of the signs of air leaks, sealing ducts should be high on your spring-cleaning checklist. All the tools you’ll need should be available at your local Aberdeen hardware store, or you can schedule duct sealing along with annual A/C maintenance with your HVAC professional.
If you’re a do-it-yourselfer, make sure you wear long pants and sleeves, a respirator, gloves, goggles and hard hat. Here’s how to seal ducts:
- Loose connections – Wrap all loose duct connections with metal tape. You may also spray the connection with aerosol-based sealant after taping.
- Fallen ducts – Mastic sealant is a gooey, malleable paste that offers superior duct sealing. Felled ducts fell for a reason, so paste and tape them, and perhaps use sheet metal screws, too, for a mechanical bond.
- Holes – Fiberglass mesh and mastic seal small holes and larger duct connection gaps just fine.
- Insulation – Don’t forget the insulation. All ductwork in unconditioned areas of the home, such as the attic or crawl space, should be insulated to hinder heat energy gain/loss.
