Most Orlando homes have ductwork installed in unconditioned attic spaces where summer temperatures exceed 140 degrees. This extreme heat degrades the adhesive that bonds insulation to flex duct. It causes vapor barriers to crack and peel. It accelerates the deterioration of mastic sealant at connection points. When a duct failure occurs in these conditions, the damage compounds quickly. Cool air leaks into a superheated attic while hot, humid air is drawn into your living space through return leaks. The result is a system that cannot keep up, an indoor environment that becomes uncomfortable within an hour, and energy bills that double or triple.
Central Florida's construction boom in the 1990s and 2000s produced thousands of homes with poorly designed and inadequately sealed duct systems. Many builders prioritized speed over quality. Ductwork was installed by low-bid subcontractors who lacked training in proper sealing and insulation techniques. We see the results every day. Summit HVAC Orlando has built a reputation for understanding these legacy systems and knowing how to repair them correctly.
