Should I Keep the Furnace Fan On All the Time?

Your furnace fan has two basic settings: Either you can leave it on automatic, or you can switch it to continuous mode. At Axberg, we have found that our customers are sometimes confused about which is the better option. Here’s what you need to know to make the right decision for your Rockford, IL home.

Potential Drawbacks of Continuous Mode

Continuous mode – which allows the fan to run all the time, even when the furnace is not engaged – has only one minor drawback. It uses electricity to keep the fan running and therefore causes slightly higher electric bills. However, the increase is minimal, and with high efficiency motors you may not even notice a difference in your bill.

Potential Benefits of Continuous Mode

The benefits of continuous mode far outweigh this one drawback. First, when you put your fan in continuous mode, you move the air through your home and the furnace filter more frequently. If you install a high-efficiency filter, this can lower the number of allergens in your home, improving your family’s comfort.

In addition, circulating the air can help keep the temperature even in your home, especially if you have a two-story home that tends to be uncomfortably warm in the upper floors.

Finally, running the fan continuously may help extend the motor’s life by preventing multiple stops and starts. While some believe continuous running actually hurts the motor’s life span, turning it on and off is hard on the motor, so continuous mode could help avoid this added stress on the system.

Axberg Reviews
Tuesday, 9/7/2017, We asked Axberg to come and replace some rusting vent pipe and perform maintenance on our furnace. Axberg replaced the vent pipe, cleaned the furnace, then tells us the heat exchanger is cracked and the furnace should be replaced. Axberg was supposed to send a picture of the cracked heat exchanger but didn’t. Wednesday,9/8/2017, I called the Axberg office and tried to explain why I wasn’t happy with the service. Basically, Axberg charges top dollar and in return I expect them to work smart. Smart is not checking the heat exchanger last! I wanted a break on $444 of useless work performed on the furnace. Axberg wouldn’t budge. I pointed out that now my furnace doesn’t work at all and Axberg still wouldn’t budge. Axberg suggested that if spent more money on my furnace to fix the items identified on their invoice then the furnace would work. At this point, I don’t trust their judgment or customer service. Later Wednesday 9/8/2017, I called another local company for a second opinion. My furnace doesn’t work because Axberg forgot to attach the hose to the pressure switch. I get this fact in writing. Made arrangements for a new furnace install next day. Thursday, 9/9/2017. New furnace installed, not by Axberg. Nice. Called my credit card company to dispute the bill from Axberg. Called Axberg again and this time they at least seemed willing to escalate to a supervisor. I understand that sometimes things go wrong and am waiting to see if Axberg is willing to make this right.
