“Exceptional customer service, and extremely efficient. We had our water heater go out on a Saturday! A technician was there within a couple of hours, and gone shortly thereafter - even with a trip to HomeDepot. There was no upselling nonsense, just old fashioned customer service; Brendan W. explained our options thoroughly and walked us through every step of the process. We are so grateful for Brandenburg Plumbing, Heating, & Air.”

Ductwork Services - Sealing, Insulation & Design for Better Comfort
Your ductwork is the hidden backbone of your HVAC system. Leaky or poorly insulated ducts—especially in Texas attics where temperatures can exceed 140°F—waste energy and create uncomfortable hot and cold spots. We seal, insulate, repair, and design duct systems to deliver even temperatures and cleaner air throughout your home.

FAQ
Common Questions About Ductwork
Find answers to common plumbing and HVAC questions from our expert team.
Common signs of leaky ductwork include rooms that are consistently too hot or too cold, higher-than-expected energy bills, excessive dust in your home, and your HVAC system running longer than it should. In Texas, where most ductwork runs through unconditioned attic space, leaks are extremely common and can waste 20-30% of your conditioned air. We use diagnostic tools to test your ducts and pinpoint exactly where the leaks are.
