Duct Sealing Service in Cape Coral, FL
Duct sealing closes the gaps, loose joints, and failed mastic connections in your supply and return duct system. When ducts leak, you're paying to cool your attic instead of your living space — and rooms farthest from the air handler feel warm no matter how low you set the thermostat. Sealing is done with mastic compound or metal tape, not standard duct tape which dries out and fails within a year or two.
Cape Coral AC Repair Co provides duct sealing service for homeowners across Cape Coral, FL. Call for a free inspection and a written quote before any work begins.
When to Call
When You Need Duct Sealing Service
- Two or three rooms in your Cape Coral home stay noticeably warmer than the rest of the house
- Your electric bill climbed significantly even though usage habits haven't changed
- You can feel air blowing in the attic near duct connections when the system is running
- The system runs almost continuously but can't bring the house down to the set temperature
How It Works
Our Process for Duct Sealing Service
- 1
Pressurize and Locate Leaks
We run the system and use a smoke pencil or pressure testing to find where air is escaping before any sealing begins.
- 2
Access Duct Connections
Attic access is usually required to reach trunk lines and branch connections — we work methodically from the air handler outward.
- 3
Apply Mastic Sealant
Mastic compound is brushed onto joints and gaps, then mesh tape is embedded for connections that have significant separation.
- 4
Retest Airflow
After sealing, we check room airflow and system static pressure to confirm the repairs made a measurable difference.
Cape Coral Context
Why this matters in Cape Coral
Attic temperatures in Cape Coral regularly exceed 140 degrees in summer. Any conditioned air leaking into that space is essentially wasted, and the heat gain from poorly sealed ducts forces your system to work much harder than it should.
Straight Talk
About pricing & scope
Scope depends entirely on how extensive the leakage is and how accessible your ductwork is in the attic. Older systems with flex duct that's shifted or collapsed take longer to address than systems with rigid metal trunk lines.
