Do You Think You Need Duct Sealing? Watch for These Signs.


The ductwork inside the walls and ceilings of your home must stay in top condition, without any leaks or holes. If the ducts are not airtight along their length, it will result in a loss of air pressure, and it will allow heat to either escape or enter the ducts, causing a loss of energy. To restore the integrity of damaged and leaky ducts, you will need the services of a professional duct sealing expert.

If you suspect that your ducts have leaks, contact the indoor air quality experts at Raleigh Heating & Air as soon as possible. We offer multiple services to protect your home’s HVAC system and indoor air, including air duct cleaning, duct replacement, and duct sealing in Cary, NC and the surrounding areas.

However, this brings up a good question: How will you know that you need to have sealing for your ducts? Below are some warning signs for which to look.

A Drop in Airflow From the Ducts

Loss of air pressure because of leaking is one of the first troubles that damaged ductwork will cause. If you detect that the airflow coming from the vents is weak to almost non-existent, then you either have problems with the ducts or with the HVAC system—and you’ll need to call experts to find out which.

Odd Odors From the Vents

Because gaps in vents can open onto closed in areas of the house that contain dust and dirt (crawl spaces, gaps between walls), contamination can start to infiltrate into the ventilation system. This will result in unusual smells emanating from the vents, such as moldy and musty odors. You should have this investigated right away, since it often means that your air quality is suffering.

High Heating and Cooling Bills

Loss and gain of heat, as well as drops in air pressure, will place additional strain on the heater or air conditioner connected to the ductwork. Your utility bills will start to climb when this happens. There are a number of different causes for increases in your heating and cooling bills, but faulty ducts that need sealing are one of the most common.

The longer you wait to schedule duct sealing, the worse the problems will become. The eventual drop in air quality can lead to health issues, so make sure that you call Raleigh Heating & Air for the repairs you need as soon as you sense there are ventilation system problems in your home.
