Ductwork is more susceptible to air leaks than most homeowners realize, then as much as 30% of heated or cooled air can be lost because of holes, cracks and imofficial connections, then having the duct method officially worked on and diagnosed is essential to the operation of the gas furnace and a/c, and duct sealing ensures that the maximum amount of conditioned air reaches the rooms in the home, providing more consistent temperature from room to room, however flaws in the ducts can result in a room feeling boiling or chilly, making it impossible to achieve satisfying comfort, leaks in a return duct can draw dirty air into the method and circulate it through the home; Particulates, pollen, dust and VOCS can be introduced into the breathing air… It’s possible for pests to make a cabin in the ducts… Bacteria and mold inside the ducts aggravates symptoms of allergy, asthma and other health problems, there’s even a safety risk.
If the HVAC duct runs near appliances, a flaw can allow combustion gasses into the ventilation system.
If these gasses are combustible, there is the potential for fire or explosion… When the heated or cooled air is allowed to leak out, energy efficiency suffers. The gas furnace and a/c are required to toil harder and run longer. Along with higher utility bills, the greater wear and tear and shorten service life and increase the risk of repairs. It’s pressing to inspect the HVAC duct and invest in sealing when necessary. Professional sealing processes can reduce leakage down to 2%. The procedure coats the surfaces of the pipes with an antimicrobial compound that resists the growth and spread of toxins.
