Sealing leaks on your home are much more advantageous than you think. It’s estimated that energy wastage from air leaks on average, could span from 25 percent to 30 percent. Quite alarming especially if you start to realize that this huge chunk of loss equates to an equal amount of expenses.

Leaks can make it hard for your equipment to do their job effectively, but it could also be costing you more money so it would be wise to seal them. The best option would be to have professionals deal with this, especially if the problem lies with one of the HVAC components, but it may be possible for the normal homeowner to perform this as long as they are careful and have the necessary tools.


Gradually your vents will deteriorate and it may develop holes eventually. How soon will depend on its material and how well it was manufactured and maintained. Finding these openings may not be the easiest, but if your patient enough you may check your ductwork segment by segment and use your finger to feel any air coming out. You may also wet your hands so that it becomes more sensitive to the touch of wind.

You may also opt to seal returns and registers and make use of a duct leakage tester, which is basically a calibrated fan that puts a lot of pressure into the ductwork. A blower then measures the tightness by the air and then you may then easily track down where these gaps are located.

You can’t merely use any type of adhesive to seal these. Make sure you have mastic tapes to patch these up easily and properly.

Windows And Doors

Even when your windows and doors are closed, they might not actually be totally shut. The sliding kinds are especially prone to having slits where air may pass through. If you haven’t yet, the best way to tackle this dilemma would be insulation. Even if you already have had your home insulated before, then these may already be worn out and in need of replacement without routine checks from experts.

There are different types of insulation to choose from, and what variety you’ll be needing will rely on where it will be located. Make sure you become familiar with these and take into account that sometimes these may have ramifications in terms of the functionality of your doors and windows. For example your windows might be much slower when you try to close it due to the added resistance brought by the insulation, or a carpet may be dragged by the sweep located at the bottom interior of your door.
