Leaky air ducts are a problem with almost every home (old or new) that has ductwork. These leaks cause energy waste resulting in higher utility bills, poor indoor air quality, and uneven temperatures throughout the home. At Northern's One Hour Heating & Air Conditioning®, we recommend AeroSeal Duct Sealing. The AeroSeal system uses aerosol injected particles to seal 100 percent of any duct leaks, up to 5/8-inch. Consider these factors when calculating duct sealing cost.
Advantages of Sealing Ducts
Sealing ductwork offers several advantages to the homeowner:
- Better indoor air quality
- Even temperature distribution
- Less energy waste, leading to lower utility bills
Air quality is improved by keeping pollutants from entering your duct system and being circulated through your home. Sealed ducts also lead to more comfortable and even temperatures throughout your home, especially in those rooms furthest from the HVAC unit. Equally important is energy efficiency and money savings.
Manual Duct Sealing
In addition to the aerosol injection system, ducts can be repaired manually. This is a necessity for any gaps or holes larger than 5/8-inch. The problem with a manual repair, however, is that it can be difficult to find leaks that are hidden in walls and other non-accessible areas. The primary method a pro seals leaks are through the use of mastic and duct tape.
Complete duct sealing costs will vary based on a number of factors such as the size of the house, the complexity of the job, and whether a manual or aerosol system is chosen. Although aerosol injection might seem more expensive at first, it is competitive with a manual repair job that involves removing walls to access interior ductwork. For smaller jobs with easily accessible ducts, manual repair may make better sense. Whatever method you choose, the cost can pay for itself through money saved in reduced utility costs.
