Indoor Air Quality

Between work and home life, the average person spends about 90% of their time indoors! Indoor air can be 2 to 5 times more polluted than outside air. In fact, the Environmental Protection Agency ranked indoor air quality as a top 5 environmental danger.

A well-insulated home can help with your energy bills by keeping a constant temperature, but that also leads to the same air being recycled through your home each time you run your air conditioner or furnace. Be sure you have proper filtration in place to prevent allergens and bacteria from circulating around your air.

Dean's Shop can help you breathe easy. Call us today at 512-353-4770 and we can put together a plan for your home!

Air Ducts

According to the U.S. Department of Energy’s Energy Star program, leaky ducts in attics or crawlspaces can account for 20% or more of a home’s heating and cooling energy losses. This makes it difficult to keep your house comfortable and can result in higher utility bills. Some signs that you may have leaky ducts include:

  • High Summer and Winter utility bills
  • Rooms that are difficult to heat and cool
  • Stuffy rooms that never seem to feel comfortable
  • Ducts are located in an attic, crawlspace, or the garage
  • Tangled or kinked flexible ducts in your system

Learn more about how you can detect, prevent, and fix air duct issues with the help of the professionals at Dean's Shop. Find out more about duct testing, duct insulation, and duct cleaning and how they relate to and impact indoor air quality.
