Are air ducts more prone to leaks than you might realize?

Many homeowners are unaware that nearly 99% of air ducts in homes have up to 44% leakage. According to the Department of Energy, the average home has enough air leakage to be equivalent to leaving a medium-sized window wide open. Fortunately, this doesn’t have to be the case for you. If you haven’t inspected the air ducts in your home recently, it may be worthwhile to consider reaching out to our specialist. We are dedicated to sealing any leaks to ensure your home is comfortable and safe.


The process of crawl space heat duct services can help to improve the efficiency and performance of your HVAC system, reduce energy bills, and improve indoor air quality. It is important to work with a qualified professional who has the experience and expertise to properly install, seal, and insulate your crawl space heat ducts.

the process of crawl space heat duct services

  1. INSPECTION—The first step is to thoroughly inspect the crawl space to identify any issues that could affect the heat ducts’ performance. This may involve checking for leaks, damage, or improper installation.
  2. SEALING & INSULATING—Once any issues are identified, the next step is to seal and insulate the ducts properly. This can involve using specialized materials such as mastic, foil tape, or spray foam insulation to seal any leaks or gaps in the ductwork and prevent air from escaping.
  3. REPAIR– If any sections of the ductwork are damaged or corroded, they may need to be repaired or replaced. This may involve cutting out the damaged section and installing a new piece of ductwork.
  4. VENTILATION– Proper ventilation is essential for maintaining good indoor air quality in the crawl space. This may involve installing vents or fans to circulate air and prevent moisture buildup.

Frequently Asked Questions About crawl space heat duct services

Sweating happens when the heated air touches a cold surface or vice versa. The best option is to insulate your crawl space air ducts. This also improves your HVAC system’s energy efficiency. 

Ductwork insulation in the crawl space is a simple add on if you are getting the entire crawl space insulated. The investment is nothing compared to the return since uninsulated ducts can lose up to 30% of their heating and cooling efficiency. 

Spray foam insulation doesn’t do well around heat sources. We don’t recommend it on air ducts; it is less effective than duct wraps. You can use spray foam insulation to seal around HVAC boots that penetrate through the drywall or around where wrapped ducts connect to the boots, but it’s not recommended on duct work.
