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. In addition to repairing and sealing existing ductwork, we can completely replace outdated duct systems with newer, more efficient materials. Modern ductwork provides a tighter seal, helping reduce air leakage and improve overall system performance. In many cases, newer duct materials also offer a higher R-value, enhancing insulation and increasing energy efficiency throughout your home or business.

FAQ
Duct Sealing questions, answered
How much can duct sealing save?
It varies by how badly the ductwork is leaking, but recovering air lost to a hot attic can meaningfully cut a Florida cooling bill — and just as importantly, it will reduce the humidity level within the home.
How is duct sealing different from duct cleaning?
Duct cleaning and duct sealing address two different issues. Duct cleaning removes dust, debris, and other contaminants from inside the ductwork, while duct sealing focuses on closing leaks, gaps, and disconnected joints that allow conditioned air to escape and unconditioned attic air to enter the system.
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 of work and price in a free in-home estimate first.
