Sealing and Maintaining Your HVAC Ducts

Did you know your duct system is the most neglected component of your entire HVAC system? As such, it needs to be maintained in order to operate at peak efficiency. We know, ducts are easy to forget because they're in the walls and ceilings: out of sight, out of mind, right? Well, you'll need to step it up a notch when it comes to maintaining and sealing your duct system to extend the life of your system, keep your energy bills low and keep repairs at bay.
Importance of Sealing
HVAC ducts carry hot and cold air to various rooms throughout your home. To do that job efficiently, the ducts must be sealed up tight to ensure no loss of energy happens. Over time, ducts can develop holes and cracks, registers can loosen and the ducts themselves can rot. What happens when you have holes or gaps in your ducts? You guessed -- the heat and cold air can escape. This costs you more money in energy bills because your system is working overtime just to reach the desired comfort level within the home. This also puts undue stress on your HVAC system, which can shorten its life span. You also run the risk of letting low-quality air infiltrate your home, leading to asthma and allergy flare-ups or worse.
Fortunately, all of this can be avoided with proper sealing and maintenance.
What to Do
An inspection of your ductwork is in order, at least once a year. Sixty-six percent of homes feature leaky air ducts, accounting for 20 percent or more of your home's heating and cooling energy losses, says HGTV. It's best to hire a professional for this job, but if you're a handy DIY'er, you can attempt a few small repair jobs. While you can apply mastic tape -- forget the duct tape -- to small holes that you can see, this isn't an easy option for larger holes or holes that you can't readily see from your vantage point. You can also apply foil-backed tape to any questionable areas, sealing behind registers and grilles and where the duct work meets the wall.

That being said, tiny imperfections, gaps and holes could be letting air through and you don't even know it. Even if you did know about it, it would be near impossible to reach certain areas of your duct work. That's why you need a professional. Here at TDI Air, we'll come in to provide an inspection and tune-up of your duct system, run some tests (i.e., for air pressure) and give you a free quote on the work to be done.
You may need to add insulation to your ducts to prevent heat and cold loss. For example, if you currently have ducts and basement walls that are un-insulated, you should think about getting this job done. Another option is to add more insulation in your attic and go with a smaller HVAC unit for the home. You should also have your ducts cleaned by a professional each year or two to ensure no build-up or blockages have occurred, and that the unit has solid combustion efficiency, air flow and hydronic balance. Change your filters every couple of months to keep them free from debris and the air flowing freely.
