Duct Sealing Serving Southern Oaks — Aeroseal & Mastic
Duct leakage in Southern Oaks homes can waste 20-30% of your cooling before it reaches a register. We run a CFM25 pressure test before we touch anything, seal the leaks with mastic or Aeroseal where appropriate, then retest and show you the numbers.
What makes Southern Oaks different for HVAC
Southern Oaks sits in traditional subdivision with many homes built in the 1960s-1970s. It's inland enough that salt-air corrosion is minimal, with no HOA, so exterior unit placement and screening are up to you. Locals know the area by landmarks like Southern Oaks Middle School, NE Saint James Dr, St Lucie River north fork.
original flex ductwork from the 1970s is still in many homes here — leaks add up.

Common questions from Southern Oaks homeowners
How much duct leakage is normal in Southern Oaks?
Energy Star target is under 4 CFM25 per 100 sq ft. Most pre-2005 homes test at 3-5x that. Post-seal we're usually back to target.
Aeroseal or mastic?
Depends on access. Exposed attic runs: mastic. Inaccessible chases or wall cavities: Aeroseal. Often both on the same job.
Will I actually see a utility bill difference?
If your test shows 20%+ leakage, yes — typically 8-15% summer savings. If leakage is low already, the ROI isn't there and we'll say so.
