Typically speaking, most forced air heating and cooling systems lose around 25% of energy to air duct alone. Metal and stretchy-plastic ventilation can only be insulated so much to prevent cool air leaking into a sizzling summertime attic, or a freezing Wintery attic’s air from entering the warm Heating and A/C system. Although different degrees of insulation in weird brands and quality levels are available, there is always going to be some degree of leakage through the material. But that doesn’t cover everything with air duct and leaks. Much of the time there are tiny hairline cracks or times where there are joints in your ventilation system in the places where a section of metal air duct connects to another, or anywhere there are welded joints, for instance. One of the smartest, easiest, and quickest ways to find leaks in the air duct is via a smoke test. Smoke tests utilize a small smoke candle or cartridge that is put inside the air duct for the test and is allowed to pass through the air duct while the program cycles. As the smoke moves through the Heating and A/C program and directly into the building, a separate tester watches from inside the attic or the crawlspace where the ducts are located. The purpose is to monitor for occasions where smoke would be seen flowing out. If there is a big enough crack or leak, considerable amounts of smoke will be seen immediately. These tests are straightforward and can be done without a professional if the directions are closely followed. Once the leak is located, repairing it will be less of a headache for the next HVAC company that will come over to service the problem.
