Improve Efficiency and Reduce the Need for HVAC Service By Sealing Your Air Ducts

Air Conditioning

If your heating and air conditioning is not as efficient as it used to be, you could be losing conditioned air through your air ducts. Air duct leakage is one of the most common reasons that homeowners lose efficiency in their HVAC system and require HVAC Service. In fact, as much as 20 percent of your energy could be lost in your duct system. Cracks in the ducts and broken seals are the main causes of leaks and lost energy-efficiency. Closing registers in rooms that you don’t use can further reduce the efficiency of your heating and cooling system and result in air leakage.

Indoor air quality can also be affected by air duct leakage. If you or your family has unexplained respiratory problems that seem to worse inside your home, leaks in your air ducts could be the problem. When ducts are not tightly sealed, dust and other allergens can get into your ventilation system and get blown into your home through your registers. Some homeowners may think that they need their ducts cleaned when they really only need them properly sealed. By sealing the ducts, you may reduce respiratory symptoms if you or a family member has asthma or allergies.

Depending on how much air you are losing through your ducts, your energy bill may be higher than normal while your home is less comfortable. Because the air coming from your heating and air conditioning units is not reaching the livable space in your home, your equipment has to work harder to keep you comfortable. This lost efficiency can cause premature aging of your equipment and higher monthly energy bills. Your HVAC Service technician can assess your air ducts to determine if they are leaking and seal the leaks so your heating and air conditioning systems run more efficiently.

Advantage Service Company uses the Aeroseal system to find and seal leaks in air ducts. The computerized system can diagnose leakage issues within a home’s duct system and seal leaks that are not readily accessible to the technician.
