Common questions

Why is my upstairs always hot in summer?

Usually a combination of duct leakage, undersized returns, and long duct runs losing cool air before it arrives. Duct sealing and balancing often fixes it for far less than a new system.

Is duct sealing worth the money?

If your ducts run through an attic, crawlspace, or unfinished basement — very often yes. Sealing typically pays for itself in energy savings, and the comfort improvement is immediate.

Do you do duct cleaning too?

We assess honestly first: many homes don't need cleaning, they need sealing. If cleaning is genuinely warranted (post-renovation dust, pest issues), we'll tell you and handle it properly.
