Duct Sealing: A Simple Path to Better Comfort, Lower Bills

The climate in Florida makes it hard to predict whether you’ll need to run your heating system or your AC from day to day during the winter. But there’s one part of the HVAC system you use every day, no matter the outdoor weather, and that’s the ventilation system.

A ventilation system with air leaks will mean trouble for your house, no matter if you have the air conditioner or the furnace running. The best way to solve this universal HVAC concern is through professional duct sealing services.

The Problems with Air Leaks

The ductwork in a home is designed to have an airtight seal all the way from where it leaves the air handler on the HVAC cabinet to the point where it meets the duct registers in the room. This applies to the return air ducts as well. This seal is designed to maintain air pressure throughout the HVAC system.

If the ductwork has air leaks, the air pressure in the ventilation system begins to drop. This seriously reduces the efficiency of the HVAC system. The airflow from the vents declines and results in reduced comfort around the house.

According to the U.S. Department of Energy, air leaks in ducts can account for a loss of up to 30% of the air moving through the ventilation system. This means energy going to waste in closed-off parts of the house, such as between the walls and up in the attic. Losing cooled and heated air to these places is a waste of money: the HVAC system will have to work harder to make up for this loss, and this will show up on utility bills. The extra strain places on the HVAC system can also mean more frequent breakdowns and possibly the need for an early system replacement.

The Duct Sealing Solution

You might hear the word duct sealing and think, “Ah ha! This is the true purpose of duct tape!” and run to get a roll of it. But this isn’t duct tape’s true purpose. In fact, duct tape is almost useless on ducts because the temperature changes make the tape brittle and cause it to fall off.

Real duct sealing is a job for HVAC professionals who have the right tools. Sealing ducts starts with duct testing to determine how badly the ventilation system is losing air. The professionals can then begin to target the air leaks to seal them. The most common techniques to make the ducts airtight again are mastic sealant and metallic tapes. (These are the true “duct tapes.”) Once the professionals are finished, they’ll do testing again to see if they’ve succeeded at sealing the ventilation system.

Once you’ve have your home’s ducts sealed, you can expect improved comfort performance from the HVAC system and a return of your heating and cooling bills to normal.
