Duct Sealing & Insulationin Kendall, FL
Measured duct leakage testing and sealing so the air you pay to cool reaches the rooms.
Duct Sealing & Insulation for Kendall buildings
Forty-year-old attic ducts in Kendall are often grey flex duct with a brittle outer jacket, or duct board with failed tape at every joint. Air lost in the attic never reaches the bedrooms at the end of the run. We pressure-test the duct system and show you the leakage figure before recommending sealing or replacement.
Typical duct systems lose a significant share of their air through leaks at joints and connections. In a Florida attic that means cooled air is lost into a space that is hotter than outdoors, while return leaks draw humid, dusty attic air into the house.
We measure leakage with a duct pressure test before and after the work, so you have a figure to judge the result by.
Why seal the ducts
- Lower run times and electric bills
- More even temperatures between rooms
- Lower indoor humidity
- Less dust entering through return leaks
- A smaller, cheaper system may be enough at the next replacement
How it works
- We pressure-test the duct system and record total leakage.
- We seal joints, boots and plenums with mastic and approved tape.
- We repair or add insulation where it is missing or damaged.
- We retest and give you the before and after numbers.
Duct Sealing & Insulation in Kendall: questions
Is duct sealing worth it on an older home?
Older homes usually benefit most, as long as the duct material itself is still sound. If the ducts are deteriorated, replacement is the better investment and we will say so.
Is a permit required for HVAC work in Kendall?
Installing or replacing air conditioning equipment in Kendall requires a mechanical permit and a final inspection. Permits here are issued by Miami-Dade County, since Kendall is unincorporated and has no city building department. Repairs, maintenance and cleaning do not need one. We file the paperwork and attend the inspection.
Who issues AC permits in Kendall?
Kendall is an unincorporated community, so mechanical permits come from Miami-Dade County's permitting office instead of a city building department. We file the permit, schedule the county inspection and meet the inspector on site.
Why are the back bedrooms in my Kendall house always warmer?
On single-storey Kendall homes the bedrooms are usually at the end of the longest duct runs. Leaky or crushed attic ducts and an undersized return are the usual causes. We measure airflow at each register and fix the duct problem, which is often cheaper than replacing the air conditioner.
