Knowing When Your Furnace is on the Fritz

Table of Contents

As the bone-chilling Wisconsin cold gets in full swing of things, everyone begins to hunker down. The winter means that it’s time to drink hot cocoa while reading a book, adding layer after layer of clothes before braving the outdoors, and getting ready for the holidays. We all take for granted the warmth and coziness that our homes provide us during the cold. That is until your furnace stops working. Not only will you not be comfortable, but under frigid temperatures, your family and pets’ health are in danger. Don’t worry, even if your furnace completely gives out, Rock Valley HVAC, Inc. will be there in a heartbeat to provide expert furnace services to your home in Southern Wisconsin to get your furnace back in working order.

However, we want to provide you with a few warning signs that might indicate that your furnace is struggling, so that you can prevent complete failure. If you’ve noticed any of the following, don’t wait to contact us immediately! We provide commercial and residential furnace services including furnace repairreplacementcleaning, and more!

Strange Sounds

Have you been hearing weird sounds that go bump in the night? This could be one of two things. Either you have a ghost, which we can’t help you with, or your furnace is calling for help. When you hear pops, rattling, or banging sounds from your furnace, this likely means that a part has shaken loose and needs to be replaced, or your furnace has found itself on its last leg. Either way, don’t ignore it and give our HVAC experts a call.


Unfortunately, furnaces don’t last forever. The typical lifespan of a furnace is around 15 to 20 years, so if this rings true for yours, then it’s time to say your goodbyes and start looking for a new unit. If you have no idea where to start your search, don’t worry, we’ll be able to give you a few options that would work for your home.

Bills Have Gone Through the Roof

Another clear indication that your furnace is giving up is if your monthly heating bills have all of a sudden skyrocketed. Although it will try to keep your home warm, if it is older or isn’t working efficiently, then it is going to work overtime to try and catch up. By doing this, it exerts more energy which will add to your energy bill.


Like most things, your furnace requires a little TLC from time to time. If you’ve neglected it for over a year, then your going to want to have one of our professional HVAC specialists to come out and give it a look. We recommend annual maintenance checks to ensure that your heating unit is in working condition.

If you come home and your house is freezing, it either means that the bills haven’t been paid or your furnace has kicked the bucket.
