According to ENERGY STAR, about 20–30% of the air moving through a typical duct system is lost to leaks, holes, and poor connections. In Orange County homes — especially with ductwork running through hot attics — that means higher bills, rooms that never get comfortable, and more dust. Professional duct sealing fixes it, with flat-rate pricing, HERS duct-leakage testing, and no upsells. We are family-owned, licensed (California CSLB #1062690), and rated 5.0 stars across 200+ reviews.
Signs your ducts need sealing
- Energy bills higher than they should be for your system’s age
- Some rooms never reach the temperature you set
- Excess dust, even after you change the filter
- Whistling or air-rushing sounds from the ducts
- Ductwork running through a hot, unconditioned attic
How our duct sealing works
- Inspect & test — we locate leaks and measure duct leakage.
- Seal — we seal joints and connections with mastic and proper materials, not just tape.
- Verify — a HERS duct-leakage test confirms the improvement and keeps the work code-compliant.
What you get
Lower energy bills, more even room-to-room comfort, less dust, and a system that does not have to work as hard — which extends its life. You get a flat-rate quote before any work begins.
Duct sealing questions
How much can duct sealing save me?
Because 20–30% of conditioned air is commonly lost to duct leaks, sealing can meaningfully cut cooling and heating costs. The exact savings depend on how leaky your ducts are now, which we measure before and after.
Do you test the ducts?
Yes — we run a HERS duct-leakage test so the improvement is measured, not guessed, and the work is documented to code.
