Get Your Ducts Sealed Before Heating Season Starts

air-ductConsidering what the entire area just went through, it may seem rather crazy to be thinking about something as seemingly insignificant as HVAC systems. Believe us, though, you’re going to want to make sure these systems work in a couple of months when the weather starts to cool off. As you start to get things back in order over the next weeks and months, it wouldn’t be a bad idea to start making sure that your heating and ventilation systems are in good shape. One of the key components of making sure that your heating system is ready for winter is the ductwork.

The Importance of Healthy Ducts

Even as far as HVAC goes, the ducts may be the bottom of the list of your priorities right now. We understand. Dcuts don’t have moving parts to short out or otherwise ruin. Ducts don’t need electrical or gas work done on them. Hopefully, the ducts weren’t even touched by the floodwaters. However, if you haven’t had them sealed in a while, it might be a good idea to arrange for duct sealing services throughout Brazoria, TX.

Ducts develop leaks over time, just from years of normal use. Expanding and contracting with the temperature of the air causes gaps to form between segments, and things like small animal activity can make their own holes at times. While the individual leaks in the average ductwork may be small, they add up fairly quickly. In fact, the U.S. Dept. of Energy has found that the average centralized forced-air system loses as much as 30% of its total output to duct leaks. That means your climate control systems have to work harder to effect temperature changes, and that means you will have to pay more from month to month.

Duct leaks also allow more airborne contaminants to enter into the system, where they are then circulated around the house. These are things like dust, pollen, dander, viruses, bacteria, and mold spores, which can cause a wide array of different negative health effects. For the sake of your health, comfort, and wallet, it’s a good idea to have your ducts sealed at least once every few years.

The Process

How the ducts are sealed varies slightly, depending on the situation and the personal preferences of the technician. The most common way is to use a substance called mastic to seal the leaks. Mastic is a kind of putty or epoxy shaped to fit the hole that it’s plugging. The mastic can flex and move with the ducts without cracking, which helps to keep the leak sealed. In many cases, regulation metallic duct tape supplements the mastic seal. Unlike the cloth-backed duct tape you’re probably used to (which is ironically bad for actual ductwork), regulation duct tape has a layer of metal in it. This allows it to more closely adhere to the seal, helping to prevent any air from leaking out and protecting the mastic.
