Duct Sealing Serving Tesoro — Aeroseal & Mastic
Duct leakage in Tesoro 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 Tesoro different for HVAC
Tesoro sits in master-planned community with homes built from the mid-2000s onward. It's within a few miles of the coast — not heavy salt exposure, but not inland either, with gated — we coordinate guest access with your gate attendant before the truck arrives. Locals know the area by landmarks like SE Via Tesoro Blvd, Becker Road, St. Lucie River.

Common questions from Tesoro homeowners
How much duct leakage is normal in Tesoro?
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.
