Ductwork Repair, Sealed With Mastic That Holds
Ductwork is the delivery system. Your AC cools air in one place, then ducts carry it everywhere else in your home. Sounds simple. But ducts leak. They sag. Joints come apart. Insulation breaks down in attic heat that can hit 140 degrees on a Paradise afternoon. The U.S. Department of Energy puts the typical loss at 20 to 30 percent of conditioned air, leaking out into attics and crawl spaces before it ever reaches your rooms. That is air you paid to cool. Money escaping into a hot attic.
Repair work is hands-on, mostly attic work. We measure static pressure across the system first. High static pressure usually means restriction. Low static usually means leaks. CFM at the registers tells us where the loss is happening. We seal leaking joints with mastic, a thick paste that stays flexible and actually holds in Paradise heat, unlike regular duct tape which fails within two summers. We replace flex duct that has been crushed or torn. We reattach runs that came loose from boots, plenums, and trunk lines. We re-wrap insulation jackets where they have split. R-value matters here. R-6 minimum, R-8 if the attic runs hot, and Paradise attics run hot. Most homes do not need a whole new duct system. They need the worst three or four spots fixed properly. Ductwork repair handles the duct system itself, the trunks, branches, and connections. For repair of individual duct components and vents, see our broader air duct repair coverage.
