Checking For Air Leaks

Autumn has been here for a few weeks now, which means winter is just around the corner. We here at Dowd Mechanical Heating & Air Conditioning know that Pennsylvania winters can be some of the worst nature can offer. Your heating and air conditioning system is the first line of defense against the icy chill of winter.

If you have air leaks in your system, you could be facing a 25%-30% energy loss in your home or business, not to mention having to wear your winter clothes inside! Read on to learn how you can check for air leaks yourself and stay warm this cold season.

Do I Have An Air Leak?

Checking for air leaks can be time-consuming, so make sure you set some time aside to get started on this task. There are tell-tale signs to your home losing potential heat. Have you noticed a higher than usual utility bill? Are certain rooms difficult to maintain at the desired temperature? Do you feel you keep having to mess with the thermostat? Do you feel small breezes near window sills?

Air leaks can cause the air in parts of your home to become stuffy and lead to excessive amounts of dust in areas with poor circulation. If you’re experiencing any of these, you may want to consider checking your system for leaks. Not to worry, all you’ll need is a grease pencil and something that emits a trail, like a smoke pencil. If you proceed with a candle and smoke, be very cautious of the flame.

How To Check For A Leak

Sometimes, it’s as easy as visual or physical confirmation. Turn your system on to a setting so that it is running without stopping and then head each of the windows in your home and to where the air ducts are in your home (typically the attic). By placing your hand near the duct joints or window seals, you’ll be able to determine if there’s airflow. Be patient and see if you can feel a cool breeze. This would dictate that cool air is seeping into your home. Larger leaks will be easy to feel in this manner, and you should label any area you find.

If you don’t feel any leaks but still suspect your system is leaking, you can use something like incense, candle (blowing out the flame to emit smoke), or a smoke pencil and hold it to the joints. A leak will cause a disruption in the trail of smoke. If you have utilized these options and still can’t find a leak but are experiencing the symptoms of one, give us a call!
