Frequently Asked Questions About
Air Duct Sealing in Virginia

People often look for DIY solutions for expensive problems. Unfortunately, duct sealing isn’t something you should attempt on your own. Although you can find mastic sealant at most hardware stores, you shouldn’t try to use the sealant to seal the ducts from inside. In the process of attempting to seal the ducts, you could cause harm to the ducts or the system in general.

First, you might notice high energy bills. If you have a sudden spike in your electricity use and have no explanation for it, you should think about speaking with an HVAC technician. Air could be leaking out of your HVAC system, which makes it work even harder to keep your home comfortable.

On your own, there is a way for you to check for leaky ducts. You can take your hand and place it up to the seams in your ductwork. If you feel air coming out, you have a leak. But this isn’t the best way to check for leaks because you could end up missing a few leaks. The only truly effective way to check for duct leaks is to call a professional.
