Leaky ducts can waste up to 30% of the air you pay to heat and cool. Green Home Services seals ductwork for San Antonio and Austin homes, improving comfort, lowering energy bills, and keeping your air cleaner.
Small gaps and leaks in your ductwork let conditioned air escape into attics and wall cavities before it ever reaches your rooms. We locate and seal those leaks so your system delivers air where it belongs. The payoff is more even temperatures from room to room, lower energy bills, and less dust and unconditioned air being pulled into the system.
Ductwork is the delivery network for your entire heating and cooling system, and when it leaks, everything suffers. Industry studies show leaky ducts can waste twenty to thirty percent of the conditioned air moving through them, air you have already paid to heat or cool, letting it escape into attics, crawlspaces, and wall cavities. The result is uneven temperatures, rooms that never feel comfortable, higher energy bills, and more dust and contaminants pulled into the system through the gaps. Professional duct sealing closes those leaks, so conditioned air reaches your living spaces, temperatures even out, efficiency improves, and your air stays cleaner. For many homes, the energy savings make sealing pay for itself over time.
