Duct Sealing Serving Rivergate — Aeroseal & Mastic
Duct leakage in Rivergate 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 Rivergate different for HVAC
Rivergate sits in commercial corridor with a mix of housing eras. It's close enough to the Atlantic that salt air is a real factor in condenser lifespan, with HOA rules vary — we'll check yours before we quote exterior work. Locals know the area by landmarks like Rivergate Plaza, Publix #1378, Veterans Park at Rivergate.
ductwork condition depends on the original build year.
- Salt-air corrosion is a real thing here. Condenser coils in Rivergate tend to pit and leak 3-5 years sooner than inland units. We inspect for green copper oxide at every visit.

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