All About the Lennox ML195 Gas Furnace

Posted: 2020-02-11

The average lifespan of a home gas furnace is between 15 and 20 years. If your existing unit is around this age or so, you might want to consider replacing it with a new one for several reasons.

First, an old furnace lacks efficiency so it tends to work overtime to keep your house warm. This results in higher energy bills and frequent repairs. If you notice a significant increase in your heating and repair costs, it could indicate that your current unit is about to retire and would require a replacement.

Second, inconsistent heating or hot and cold spots is another issue an old, inefficient furnace produces. If you have an old furnace, you may be suffering from uneven heat distribution — some rooms are considerably warmer than the others.

Finally, it is very normal for a furnace to create some noise when it starts or while running or when it shuts down. However, if those noises begin to be excessively louder, it may be time to shop for a new unit. These sounds are signs of certain parts within the furnace, which are deteriorating and needing replacement. The problem is that as furnaces get older, finding replacement parts gets more and more challenging.

If you notice any of these warning signs, you may have come to a point where getting a new furnace would make more sense than trying to keep your old, inefficient unit.

For professional help, call your preferred heating company in White Bear Lake MN. Four Seasons Air Specialists is a good place to inquire.

This article highlights the Lennox ML195, one of the models in the Merit Series of furnaces.
