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.

A & L Heating and Air can help you breathe easy. Call us today at 865-856-8797 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 A & L Heating and Air. Find out more about duct testing, duct insulation, and duct cleaning and how they relate to and impact indoor air quality.

Humidifiers and Dehumidifiers

The comfort of your home not only depends on the air temperature but also the amount of moisture in the air.

Cold weather typically means dry, uncomfortable air. Dry air can cause respiratory problems as well as damage wooden furniture. Whole home humidifiers emit water vapor to increase the humidity in your home.

On the other hand, hot weather can mean thick, humid air. This can lead to condensation on your windows, mold spots on walls or ceilings, blistering paint or peeling wallpaper, just to list a few issues. A whole home dehumidifier removes excess moisture from the air in your home.

Humidifiers can improve your indoor air quality as well as positively impact the overall health of your family and health of your home. Controlling the humidity in your home will help protect not only your respiratory system but also your wood floors, furniture and artwork.

Let the professionals at A & L Heating and Air help you decide what’s best for your home! Call us at 865-856-8797 or request service online today.

Heat Pump Repair in Louisville, TN 37777

“Recently, on the coldest nights of the year, with ice and snow covering everything, my heat quit working. Frantically, I called every HVAC service in town, and only one, A and L, said they could help me. The person that I spoke to, I'm sorry I can't remember your name was so kind and helpful.
And Mr Timothy Holler, the technician, was incredibly professional, knowledgeable, respectful, clean and cared about my dog! He was able to quickly diagnose the problem and made the necessary repairs. He also walked me through what I could do if it happened again. And another thing I really liked about this company, is that he didn't try to sell me anything else. I have had other HVAC companies try to do that.
I highly recommend this company and give them 10 Stars!”
