Is Duct Insulation Necessary?

Duct Insulation
Reading Time: 3 minutes

In South Florida, where the climate is hot and humid the majority of the time, it is essential to have an air conditioning unit installed in your home. Air conditioners, by design, are installed to release clean, cool air into a room, and maintain the set air temperature. Unfortunately, in many situations, this is not always the case.

Are you frustrated because your air conditioner is not providing the cool, clean air that you expect or is the air quality, okay, but the unit is so noisy? If you identify with any of the above, you possibly have an air conditioner with ducts that have not been insulated.

Why Do Air Conditioner Ducts Need To Be Insulated?

Although mostly hidden, the air conditioner ducts play a vital role in getting safe clean air into a room, at the correct temperature. Most air conditioner ducts are insulated, for the following reasons:

  • Cost Saving – retention of air temperature
  • Better air quality
  • Prevention of air leaks
  • Noise Reduction

Cost Saving – Retention of Air Temperature

An air conditioner’s function is to remove the humidity in the air, cool it, and distribute it to the rest of the home. The thermostat switches off when the air in the room reaches the desired temperature. Insulated ducts are better at retaining the air temperature during transport, so the room cools quicker. Once the desired temperature is reached, the thermostat switches off, conserving energy, prolonging the unit’s lifespan, and reducing utility bills.

Better Air quality

Non-insulated ducts tend to develop small holes. These small holes allow dust and insects to enter the system, so the air that reaches the room is not as clean as it should be. Contaminated air makes breathing, especially for people with allergies, more difficult.

Non-insulated ducts allow condensation to form, which encourages mold growth. The air that reaches the room may contain dangerous mold spores that could result in severe respiratory illness, especially in asthma sufferers.

Prevention Of Air Leaks

Uninsulated ducts are prone to developing small holes and tears. Any break in the duct system will result in air leakage, with the knock-on effect of the unit having to work harder to deliver the air, at the correct temperature, to the building. Leaking ducts are the direct cause of high utility bills and the reduced lifespan of the unit.

Noise Reduction

Many air conditioners, especially larger industrial models, used in healthcare facilities, factories, and restaurants, can be very noisy. Insulating the ducts has shown to be exceptionally beneficial in minimizing the noise.

How Are Air Conditioner Ducts Insulated?

Air conditioner ducts are composed of a variety of materials and have various ways of being insulated. Art Plumbing, Air Conditioning & Electric install HVAC Insulated Flex hose ducts and insulate them with glass wool material. These double-ply insulated flexible hoses are made of aluminum foil and PET film layers. There are many compelling reasons for choosing this material including:

  • They are competitive and cost-effective
  • They come in a variety of sizes
  • They are shiny and look good in any setting
  • They tolerate temperatures between 20 to 160 degrees Fahrenheit
  • They maintain their structural integrity, yet are compressible and easy to transport.
  • They maintain the temperature of the air in the hose
  • They can be used on both permanent and mobile air-conditioners
