When you think about ways to lower your energy bill, the state of your ductwork probably doesn’t make the list. Items that top the list are usually insulation, windows, or a more efficient HVAC system. While all those things will certainly help, you will still pay more than you should in energy costs if you have leaky ducts. While we hear a lot about airduct cleaning, air duct sealing often gets neglected, but not by Atlantic Bay Contracting!
Here’s how air duct sealing can make your HVAC system more energy efficient.
Identify the leaks.
Before we get into the benefits of having a professional seal your air ducts, let’s look at how you know your ducts are leaky.
Take a look. Much of your ductwork is hidden from view, but you can visually inspect the areas that are easily accessible. Check the seams and joints for gaps.
Feel the air. While the HVAC system is one, go to the accessible areas. If you can feel air coming from the joints or seams, you need to seal the ducts.
Call a pro. Professionals have methods to check for leaks in ductwork that are more accurate than what you can do yourself. They have tools to measure airflow and to seal off the ducts, forcing air out of any leaks.
Save energy, save money.
HVAC systems heat and cool a building by directing air through the ducts to the rooms that require temperature control. When there are leaks in the ductwork, the climate control system has to send more air through the ducts to make up for the air escaping from the leaks. According to Energy Star, leaky ducts can make your HVAC system up to 20% less efficient. That drop in efficiency can increase your energy costs but up to 30%. That’s a significant impact and a jump in your heating and cooling costs that you will definitely notice.
Added Benefits of Duct Sealing
Leaky ductwork can cause more problems than just increased energy costs. Leaks in the ducts can also cause mold and poor air quality. When air of different temperatures and humidity levels come into contact, it causes condensation.
That added moisture is an opportunity for mold to grow in areas that you are unlikely to notice for a while. Gaps and leaks in the ducts can also allow the particles that the HVAC system is supposed to filter out to escape back into living and working spaces.
