The consequences of leaking air ducts can be extremely high, so it\u2019s important to know if your house has duct leakage. You can then arrange for a professional to seal the ducts and restore the integrity of the ventilation system.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Of course, that leads to the question of how to detect if you have duct leakage in the first place. The ducts are well-hidden within a home, so you can\u2019t visually inspect them. But there are other signs you can watch for:<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">A drop in airflow from the vents<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">One of the immediate effects of leaks in the ductwork is that\nit lowers the air pressure in the ventilation system. Ducts must be kept airtight\nto maintain air pressure, and the consequence of a drop in air pressure is that\nthe airflow from the vents will also drop. If you put your hand to the room\nvents and notice the airflow is weaker than normal, it may be duct leaks.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Uneven comfort around the house<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Lower airflow will also mean rooms cool down\/heat up slower, which will lower comfort around the house. This will happen unevenly: certain rooms will still feel normal, while hot and cold spots will appear in others. Duct leaks aren\u2019t the only cause of uneven comfort, but it\u2019s a serious problem no matter what the source.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Odd odors from the vents<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Leaks in the ducts will allow air from closed-in spots of\nthe home to infiltrate the ventilation system, such as between walls and from the\nattic. This will carry a musty and sometimes moldy odor to the rooms. <\/p>\n\n\n\n<h3 class=\"wp-block-heading\">A rise in energy costs<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">The biggest chronic effect that duct leaks have on an HVAC\nsystem is that they place more stress on the blower, heater, and air\nconditioner. Around 30% of the air moving through the ductwork can disappear\nthrough leaks, and this is air you\u2019ve already paid to heat\/cool and push into\nthe ventilation system. The HVAC system will need to put in extra work to\novercome this deficit\u2014and that means energy bills will rise. If you see steeper\nbills to heat and cool your house and you can\u2019t account for the change, you\nprobably have duct leaks.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Solving the Problem<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">If you suspect duct leaks, the next step is to contact our\nprofessionals. We will test the ventilation system to find out if it has leaks\nand how extensive they are. If you do have leaky ducts, the next step for us is\nto seal the leaks. We use a range of methods to ensure your ducts will be\nrestored to airtight condition once more. (By the way, store-bought duct tape <em>isn\u2019t<\/em>\na method we use. This \u201cduct tape\u201d is not actually useful for ducts.) <\/p>\n\n\n\n<p class=\"wp-block-paragraph\">To schedule duct testing and <a href=\"\/duct-services\/duct-sealing-testing\" target=\"_blank\" rel=\"noreferrer noopener\" aria-label=\" (opens in a new tab)\">duct sealing in Modesto, CA<\/a>, call our professionals.
