A high-efficiency HVAC system today is very different from those made decades ago.
Consequently, home ductwork systems may not meet the requirements of today’s modern HVAC systems.
Various signs may indicate that a home’s ductwork needs to be replaced. Most HVAC contractors hear complaints from homeowners about rooms that are always too hot or people who sneeze only in certain areas of the house. A ductwork problem can also be indicated by musty smells, excessive ducts, mold and mildew, condensation, frequent cycling, hot and cold spots, and visible ductwork damage. Due to the type of existing ductwork, accessibility, and location of the supply and return ducts, even the type of ceiling material, whether it’s drywall, lath, and plaster or drop ceilings in commercial applications, the cost of ductwork replacements varies significantly between properties. Costs generally range from $350 to $550 per duct run. Many DIY projects have been done in the past. However, this is not ideal. For the proper performance of the equipment and to achieve the desired level of comfort in the conditioned space, ductwork sizing and installation are crucial. In this case, the 18-seer unit you just bought is now a 12-seer unit, reducing efficiency and potentially reducing equipment life. Insufficient or poorly installed ductwork reduces cooling capacity, uses more energy, and affects humidity levels in your house. Your HVAC system is crucial to maintaining a healthy home. One of the most overlooked components of that system is your home’s ductwork. Since it carries air to all parts of your home, the condition of your ductwork can affect your home in ways you might not realize.
