Air & Ducts
Duct Sealing in Gainesville & North Central Florida
Targeted sealing that stops costly air leaks, fixes humidity problems, and lowers your bills.
Overview
Duct Sealing done right
Duct leakage is one of the most expensive problems most homeowners never see, because it is hidden in the attic. In Gainesville’s climate, leaks let conditioned air escape and pull hot, humid attic air into your home — driving up bills and making the house feel clammy no matter how low you set the thermostat. Bertie Heating & Air inspects and seals your duct system to recover that lost air, cut the humidity, and bring your power bill back down.

FAQ
Duct Sealing questions, answered
How much can duct sealing save?
It varies by how leaky the system is, but recovering air lost to a hot attic can meaningfully cut a Florida cooling bill — and just as importantly, it reduces the humidity that makes a house feel worse than the temperature says.
How is duct sealing different from duct cleaning?
Cleaning removes dust from inside the ducts; sealing closes the leaks that waste air and pull in attic humidity. Sealing is what fixes comfort and bills.
Will sealing fix my humidity problem?
Often, yes — when humidity comes from leaky returns pulling in attic air, sealing is the direct fix. We confirm the source during inspection so you solve the real cause.
How long does it take?
Most homes are sealed in a single visit. We will give you the scope and price in a free in-home estimate first.
