Increase the Energy Efficiency of Your AC with an Attic Fan

Dedicated to providing energy efficiency while promoting the growth of geothermal renewable energy.

We all know that hot air rises, so it logically follows that the attic is the hottest part of our homes. But did you know that allowing that hot air to stay trapped in the attic can decrease the efficiency of your air conditioning? Heat trapped in attics actually radiates down, causing your AC system to work even harder. Ventilating your attic is just one way the experts at Blue Valley Heating & Cooling of Longmont suggests to make your AC more efficient.

Ventilate Your Attic with a Fan for a More Efficient AC

  1. Rooftop Fan- Like their name implies, rooftop fans are installed on top of the roof working to both remove the hot air inside and bring in cooler outside air.
  2. Gable Fan- Actually two fans are installed with this system on opposite sides of the attic, one blowing in air and the other blowing it out.
  3. Attic fans do not have to add to your energy bill either! Since they are most effective during the day, connecting them to solar panels for on-demand use makes the most sense.

An additional benefit to attic fans, besides removing hot air, is preventing the growth of mold and mildew. Ensuring the attic stay well-ventilated will also ensure that the insulation does not retain moisture and become ruined by mold spores, requiring an expensive fix and potential health problems for your family.

A potential drawback to installing attic fans is that your home’s energy efficiency could actually decrease if the attic is not properly sealed off from the rest of the house. Before an attic fan installation, it is recommended to have a professional assessment of the seal between the top floor and attic to guarantee this home improvement won’t have the opposite effect of what was intended!
