Common questions
How do I know if my ducts are the problem?
Rooms that are always too hot or cold, high energy bills, dusty registers, or a system that runs constantly are all signs. A static pressure test tells us for sure.
Do you clean ducts?
Yes — we clean registers and accessible ductwork, but honest talk: most homes don't need a full duct cleaning. We'll tell you if yours actually does.
How much of my ductwork usually needs work?
Varies a lot. Many homes just need sealing at a few key joints; others have crushed or disconnected sections that need replacement. The inspection tells us exactly what.
Will this improve my energy bill?
Usually yes. Sealed ducts can reduce energy waste by 20-30%. Bill impact depends on how leaky your ducts are today and how you use the system.
Can you do this without opening walls?
In most cases yes. We work through attic and crawlspace access. When wall access is required, we tell you before the work — no surprises.
