9 Signs That Your Furnace Needs Repair

Signs That Your Furnace Needs to be Repaired

Our colder seasons are here and now is a great time to start testing your furnace. If there are any issues with it, it’s good to know some of the signs to look out for as these may indicate that it’s time to repair your furnace sooner rather than later. Besides being a colder environment that feels like your outside, it is important to make sure that it’s working properly as you may be spending a lot more money per month on your energy bills.

 

So let’s get started with the signs, so you can diagnose yourself if your furnace is in need of being repaired.

 

    • Energy Bills On the Rise

      It might be normal to see your bills be a couple of dollars more each month (especially if the heater was on longer of course), but if usage was about the same and you notice that there’s a significantly higher increase, then there may be something wrong with your furnace as this is unusual. Another reason for this is that your furnace may be old and in need of being replaced. In fact, the U.S. Department of Energy, states that older furnace systems tend to have efficiencies that can range from 56% to 70%, while modern heating systems are able to achieve efficiencies of up to 98.5%! When you consider your utility costs year over year, it is wise to invest in a modern system.

 

    • Furnace is Making Noises

      Of course, it’s normal for any unit to make some sort of noise, but if you start to hear strange loud noises coming from your furnace, it’s important to turn it off and have it checked out right away.

 

  • Your Furnace Isn’t Making Your Home Warm

    If your furnace has been on for a couple of hours and you still notice that it has not really provided much warmth inside your home, then there is definitely something wrong and it may be because of the blower, or your filter may be dirty.

 

    • Your Furnace Thermostat Might Not Be Working

      If your thermostat is not working, you won’t be able to properly provide the heat that your home is in need of. It’s important to check your thermostat to make sure that it’s working. If it’s not, the first thing you should try is replacing the batteries, as it may just be that. If it’s not, then you’ll definitely want to get it checked out sooner rather than later as it can significantly cause your utility bill to increase its cost per month if the thermostat isn’t working.

 

    • Your Furnace Never Stops Regardless of Temperature

      If you notice that you set your furnace at a certain temperature and it never turns off, then there may be something wrong. It may also be that you have your system set to “ON”, instead of “AUTO”. If your system is set to “ON” then it’ll never turn off, so you’ll want to make sure that it’s on “AUTO” to properly test your temperature. If it is on “AUTO” and doesn’t turn off, then there may be something wrong with the fan limit switch and it’ll be important to check it out.

 

    • Your Vents May Be Blocked

      Make sure that you check all of your vents to ensure that there is nothing blocking them such as furniture or curtains. If they’re blocked, it’ll prevent the flow of heat in your home.

 

    • Your Furnace Sounds On, But Isn’t Providing Heat

      If you hear your furnace turns on and yet don’t feel any heat within an hour, then there is definitely something wrong. You’ll want to check the pilot light to make sure that it’s on as this tends to be the issue that causes this. If it is, then you’ll need to either clean or completely replace the light.

 

    • The Furnace Flame Is Yellow Instead of Blue

      If you notice that your furnace’s flame is not it’s typical blue color, then there can be a serious issue going on that could potentially be carbon monoxide or leaking gas. In that situation, you should leave your home and call your local utility company so that they can completely turn off your gas line. It would also be recommended to purchase a new unit as the units age may be what’s causing this issue.

 

  • Your Furnace Turns On & Off Constantly

    It’s normal to hear your furnace turn on and off once and a while if you have it set to “AUTO” but if you start to hear it constantly be on and off then there may be something wrong with it. This is something that is known as “over cycling”, and it may be due to a variety of reasons such as your air circulation is not being right, the thermostat is not working properly, or your filter might be dirty.
