Ardmore Fresh Air | HVAC

Many homeowners ignore the air leaks within their residences, through which heat may escape during winter and could enter during summer. In short, these things make life harder for your Heating, Ventilation, and Air Conditioning (HVAC) system. Around 10% to 30% of utility costs are wasted due to these nuisances.

These may also serve as entryways for allergens and bugs or insects. The best thing to do then is to locate them and seal them.

Getting To Work

As of this moment, you may be confused as to what classifies as a leak. Basically, it is any gap or crack that leads to the outside of your home, or towards space not intended to be served by your HVAC.

Spotting large holes is easy, but finding tiny cracks and gaps may be tricky and are the usual culprits as they can be numerous but go unnoticed by most until you actually make an effort to find them.

Doors and windows almost always have gaps in them. Check your door and see if it has one beneath it. You may easily solve this problem with a door sweep. Examine its sides and check for slits. You may patch these up with weatherstrips that are rather simple to use. Caulk can be used on cracks around window frames. These are cheap and isn’t complex. See to it that you purchase ones that are paintable as not all are.

Leaks may also be found elsewhere, like on your walls. To better locate them have someone else help you. At night shut off all the lights inside your home. Have that person go outside and shine a flashlight at different parts of the house while you check from within where the light may be visible. Make sure to mark any openings that you find so you won’t have to perform this again.

If you're not a big fan of the dark, on a windy day feel different sections of your wall. Try and see if you can notice a breeze come on your skin. That’s a sign of a leak. This is better done with wet hands as they become more sensitive to the touch of wind.

For air ducts, you’ll want to have your HVAC turned on for this one. You may also use the feel method on this with your hands. An incense could also be another option. Light it up and see if you sense its smoke being blown away as you hold it close to the around the duct enclosure. This may signify a leak that should be patched up with mastic or foil-faced tape.
