The ductwork in your home is an important part of your heating and A/C system, and faulty ducts can leak as much as 25% of the warm or cool air produced by your heating and cooling system. Duct inspections, repair, sealing, and insulation are recommended energy, saving steps and can cut down on your energy bills. Our experienced team can talk with you to determine the best system for your home so you can enjoy the greatest financial and practical benefits.

Unless you have a ductless mini split system, the air coming out of the vents inside your home could also be contaminated with indoor air pollutants that have gotten inside the ducts installed in attics, crawl spaces, or basements. If you notice excess dust coming out of your vents, this is an indication that there may be air leaks. Regular inspections and maintenance can help prevent health problems from leaking ductwork, and with our reliable Los Angeles heating and HVAC technicians, you can get quality services to keep your home functioning smoothly.
