Cracks and other openings in the doors and windows can cause air leaks in your San Antonio home. When this situation happens, you have to find a way of sealing the openings to avoid losing heat and inflating your energy bills. Here are some of the ways you can detect air leaks.
Use Your Hand
This technique works best on cold days. All you need to do is to heat the interior so that the air inside is hotter than that flowing through the cracks. After heating, place your hand around the areas where you suspect the air is leaking through. Feel around the edges of the windows and doors. If there is a leak, you will feel the cold air blowing on your hands.
Use a Candle
The candle method is used for leaks that are small. These leaks may not be detected by your hand, but a candle will do the trick. Simply light a candle and pass it near the places that are likely to let air inside your house. Pay attention to the flame because when there is a leak, the flame will shake.
Depressurize the House to Find Air Leaks
Just like the hand test, depressurizing works best on a cold day. Just turn off the furnace and turn on all the fans in your house. Once all the fans are running, light a stick of incense and pass it gently near the vents, doors, and windows. If there is a leak, the smoke from the stick will either be blown out or sucked into the house.
Use an Air Leak Detector
Leak detectors work when you point them at the area where you suspect leakages. There are lights that will either turn blue or red depending on the temperature of the air. If there is no leakage, the light on the detector will not change.
These methods also work with ductwork. Simply turn on the HVAC unit and check around the ducts for leaks using the aforementioned methods. To seal leaks you will need to use caulk or some kind of foam sealant. Weather stripping can work with doors and windows.
