You May Need HVAC Contractors to Seal Your Ducts

duct-sealing-with-caulkingWhen people think about their HVAC systems, they usually focus on the letters “AC” (air conditioning) and “H” (heating). This makes sense: comfort in hot and cold weather is vital during the year. But we recommend our customer give some thought to the letter “V”—ventilation—as well. A poor ventilation system that allows air to escape through leaks can do serious harm to a household’s heating, cooling, and budget.

Fixing leaky ventilation ducts is a job for HVAC professional with the training and equipment to get the work done in full. We’re a top HVAC contractor for Paramus, NJ and throughout the Tri-State area, and you can trust to us to restore your ventilation system with duct sealing. When we’re done, all the letters in H-V-A-C will put in their best work for your home.

How to tell you need duct sealing

This is the first step. You can’t see the ducts in your home unless you venture into the attic or peer through the grills of rooms vents. Even then, you’re only seeing a small portion of the lengths of ductwork spread through the house. It takes some sleuthing to figure out the ducts are leaky. Here are some clues:

  • High utility bills: It doesn’t matter the season or if you’re running the furnace or the AC; if utility bills take a huge leap, one possibility is air leaks in the ducts. Up to 30% of the air in a ventilation system can get out through these leaks, forcing the heater or AC must to make up the difference. You end up paying for that difference.
  • Odors from the vents: Musty and dusty air can enter ductwork through leaks, leaving a noticeable stale and unpleasant smell.
  • Rattling vents: Damage to the ducts may cause them to rattle or make other unusual noises when air passes through them.
  • Low airflow: Does it seem like less air is coming from the vents than before? Tie ribbons to the vent grills and see if the movement of air causes them to flutter. If airflow is down, it means something is wrong with the HVAC system, and leaky ducts are one possibility.

Duct testing will give you an answer

The way to find out for certain about duct leaks is to schedule duct testing with our experts. This process puts the ducts at high pressure when the vents are sealed off and measures the speed the pressure drops. The faster the drop, the more leaks. We can tell you the extent of the problem and what needs to be done to remedy it.

The professional duct sealer at work

The hands-on work of duct sealing is one for trained HVAC technicians alone. We have NATE-certified technicians who understand the best tools to use for the job, such as mastic sealant and metallic tapes. They will locate all the leaks, access them and seal them, and then perform a second pressure test to ensure they did a thorough job. After they’ve finished the work, you’ll have a duct system back in airtight shape for best performance and energy savings.
