Air Duct Sealing: Lower Your Bills & Raise Your Comfort Level


One of the most important systems in your home is your duct system. This network of ducts carries air from your furnace and air conditioner to the rest of your home.

This allows each room to receive the benefits of your heating and cooling system, and it helps keep your home at the preferred temperature.

Therefore, making sure that your duct system is properly sealed and insulated is an important part of home maintenance and will pay off in the long run.

So what are the benefits of a properly sealed air duct system, and how can you ensure that you’re maximizing those advantages? The team at Supreme breaks it down here:

Benefits of a Properly Sealed Duct System

  • Energy Savings – according to Energy Star, about 20-30 percent of air is lost in ducts that are not sealed well.
  • Money Savings – properly sealed air ducts can help reduce utility bills because the air is not being lost through leaks and holes which causes the furnace or air conditioner to work harder to make up for the loss.
  • A More Comfortable Home – keeping your ducts sealed and insulated helps the conditioned air make it to the rooms it is intended for so you don’t have annoying temperature differences and discomfort in your home.

Signs That Your Ducts Are Not Sealed Well

You can check for several things to determine if your air ducts are properly sealed. First, if you have rooms that are particularly difficult to heat or cool, it could be an indication that the ducts in that area need work. In addition, just as well-sealed ducts reduce utility bills, ones that are not well-sealed will make utility bills rise and cost you money. This is especially true in the winter and summer months when the furnace and air conditioner run most often.

Finally, if your air ducts are located in an area of your home such as an attic or crawl space, it is a good idea to check them regularly for leaks or holes, as well as insulate them to avoid wasting energy on spaces that aren’t being used regularly in your home.

How to Seal Air Ducts

The location of air duct systems can sometimes make sealing them on your own a challenge, but here are several things you can do yourself. First, look for places where the air ducts may be leaking. You may find holes within the duct or places where ducts have come loose at the joints. Seal each of these areas to prevent any more air from escaping.

According to the Department of Energy, mastic butyl tape, foil tape, or other heat-approved tapes are preferred for sealing seams and joints over cloth-backed, rubber adhesive duct tape. Make sure that all areas where the ducts connect to each other are well taped to prevent leakage as well.

Professional Duct Sealing Will Pay for Itself in Energy Savings

If you’re looking for a more permanent fix, we suggest hiring a professional in the heating and cooling industry to get the job done right. Many ducts are not easily accessible because they are hidden within the walls and ceilings, but experts have the proper tools and know-how to seal, insulate, and make any needed repairs. In the end, the cost of hiring an expert will be outweighed by the comfort and cost benefits derived from having properly sealed ducts.

Air ducts are one of the most important systems in your home and making sure they are properly sealed will greatly benefit you and your family. If you need help with inspecting and sealing your ductwork, contact Supreme Service Today online or give us a call
