Air Duct Testing and Sealing in Staten Island, NY

Because the ductwork of a home is mostly kept out of sight, it’s hard to know when something is wrong with it, such as air leaks. This is why we recommend having regular duct testing with professionals every few years. This routine precaution will discover if your ventilation system is losing air, leading to drops in pressure, wasted energy, and even reduced indoor air quality. Technicians can repair these problems with duct sealing.

When Should You Test Your Ducts?

We recommend duct testing every 3 to 5 years, or when you have reason to suspect the ducts have damage. If you’ve experienced a rise in heating and cooling costs, heard rattling sounds from the ducts, or noticed musty and humid air wafting from the vents, it’s wise to have the ducts tested as soon as possible.

If you want to know how to test ducts, the answer is simply to call professionals. This process requires special equipment to pressurize the ventilation system and then use gauges to measure the speed at which the pressure drops. Our technicians can determine how much leakage is in the ductwork based on these measurements—and how to then proceed.

The Problem with Leaky Ducts

You may wonder why this is even necessary: why ask how to test ducts when it doesn’t sound like it’s a big deal? But air leaks in ducts are significant problems. Tests have shown that a ventilation system can lose up to 30% of the air moving through it due to leakage. That means almost a third of the air that you have already paid to heat or cool doesn’t even get to the living spaces, instead escaping into unoccupied spots in the house. The loss of air creates a drop in pressure as well, and this affects comfort around the home.

Leaks in ducts can lead to an increase in dust and other pollutants entering the ventilation system and getting into the house, lowering air quality. The extra pressure placed on the HVAC system also lowers its service life and can lead to an early replacement. If your ducts suffer from air leaks, it’s vital to have the leaks sealed.
