Duct Sealing Serving Lake Forest — Aeroseal & Mastic
Duct leakage in Lake Forest 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 Lake Forest different for HVAC
Lake Forest sits in gated active lifestyle community with homes built from the mid-2000s onward. It's inland enough that salt-air corrosion is minimal, with gated — we coordinate guest access with your gate attendant before the truck arrives. Locals know the area by landmarks like St. Lucie West, Crosstown Parkway, I-95.
ductwork condition depends on the original build year.
- Many Lake Forest homes are hitting the 15-20 year mark on their first AC — the window where replace-vs-repair starts to favor replace.
- A recurring pattern we see in Lake Forest: 25-year-old systems needing replacement.
- Summer afternoon thunderstorms shake capacitors loose. If your system short-cycled after the last storm, that's where we'd start.

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