Do I Need Duct Sealing?

Every component of your air conditioner is equally important in cooling your home efficiently. Even though they are out of sight, the air ducts are a huge part of your HVAC system. Since you don’t see the ductwork day to day, you may not think about whether or not it’s in good condition. But if the sealing on your ductwork begins to fail, it can let cold air out in your attic instead of into the rooms of your home.

Sometimes the holes in ducts are small, but other times they’re significant. If you need duct sealing in West Palm Beach, Fl, our team can help. But first, you need to know the signs that your ducts need to be repaired or replaced.

Buildup of Dust

Dust can come into your home via holes in the ductwork. If you begin to notice more dust than usual, first make sure that all of your windows and doors are closed with sufficient seals. If this isn’t the problem, turn to your AC unit ducts. Small holes can allow dust to get in and blow out through your air vents and into your home. Sealing the AC ductwork can block out dust. 

Allergy Symptoms or Illness

You may not notice the dust, but many homeowners experience an increase in allergy symptoms. This is because dust and other pollutants are entering your home through the ducts even though your AC unit works to filter these allergens out. If you feel like you’re getting sick more often than usual, leaking ducts may be the reason. Sealing your AC ducts can protect your health. 


When you set your thermostat, each area of your home should be cooled equally—or at least close to it. If you have areas of your home that are significantly warmer or cooler than others, it’s a sign that your AC ducts need sealing. This is because holes are allowing cool air to escape instead of making it into your home. Depending on where the holes are, airflow to certain areas of your home may be significantly affected. 

Rising Energy Costs 

If you notice that your energy bills are getting more expensive each month, duct leaks may be to blame. Review your last few bills to check your energy usage. If you’re using more energy without a reasonable explanation, you may need to seal the ducts. If cool air is escaping before reaching your home then your AC unit is working harder to cool your home. By sealing the ducts you can ensure that all of the air is reaching your indoor rooms instead of the attic. This can greatly reduce the amount you spend on energy each month.
