Ductwork is used to move hot and cold air throughout a home. Proper duct insulation and sealing are key to keeping your home comfortable and your energy bills low. It is extremely important for the efficiency of your home’s heating and cooling systems that you have properly insulated ductwork.
Duct Leak Inspection
Leaking air ducts are a major source of energy loss. Faulty duct systems are responsible for leaking 20% of the air that passes through holes, poorly sealed or connected joints, and fallen ducts. If you experience stuffy rooms that never feel comfortable, are hard to heat and cool, or have high utility bills you likely have poorly performing ducts.
REenergizeCO uses both a blower door test and a CFM test to detect any leaks in your home’s ductwork. These tests are done by sealing the registers of the home and raising the pressure of the air in the ducts to measure the amount of leakage in the system. If the ductwork is tightly sealed, less air will need to be forced into the system to raise the pressure of the air in the ducts. Sealing ducts can increase efficiency and may even reduce the size of the heating or cooling system you need to control the temperature of your home.
Benefits of Insulating Air Ducts
Because we live in Colorado, we experience very cold winters and hot summers. In fact, summer and winter temperatures seem to come and go on a daily basis. Due to our ever-changing climate, properly insulated ductwork throughout your home is essential to keeping your home comfortable year-round.
Some benefits of having properly insulated ductwork include:
- The energy we use in our homes can be bad for the environment. Properly functioning ductwork can reduce your impact on the planet because your home will consume less energy monthly.
- Properly insulated ductwork helps with everyday comfort throughout all seasons.
- People with an allergy or respiratory issues will benefit from properly sealed air ducts because they can help minimize exposure to harmful fumes, pollutants, allergens, etc.
- Properly insulated air ducts serve as a barrier against problems such as backdraft in which harmful gases like CO2 produced by appliances within the home are pulled back in instead of released outside.
- Malfunctioning ducts cancel out the work of your heating and cooling system by up to 20%.

How Do I Know If My Ducts Need To Be Insulated?
Below are some questions you can ask yourself to identify if there are problems with your ductwork:
- Do I have high summer and winter utility bills?
- Are there rooms that never seem to be the same temperature as the rest of the home?
- Is my home constantly dusty or “stuffed up”?
- Do I own an older home? If your home is over ten years of age, your ducts may need to be replaced or reinsulated.
Have You Ever Said, “I am not getting enough air into a room.”?
This is a popular statement from homeowners. The explanation to this statement is: it is not as much about supply air as it is about return air. Most homes in Denver have adequate supply air registers; they lack enough return air to pull the hot air out in the Summer or cycle enough air in the winter. Adding return air ducts, or transfer grills to make direct paths to return air grills is usually the answer. We can do pressure diagnostics in an energy audit to determine if your duct system is balanced.
Consider Inspecting Your Ductwork
If you have any ductwork going through unconditioned space (crawl space and attic space) you need to have it assessed. Leaking ductwork in unconditioned spaces allows AC and heat out of the distribution system and out of the house. Leaking ductwork in the conditioned space still heats or cools the structure, but if your ductwork is leaking in a crawlspace or attic space, you’re losing money.
