3 Warning Signs That Indicate It’s Time To Repair Your Furnace

As we move further into the cold winter months, the strain of constant use on your furnace is only going to increase. As it does, it’s important to recognize that the chances of your furnace breaking down or developing one or more serious issues is only going to increase. Your furnace is an incredibly important part of your home and plays a vital role in keeping your home warm and comfortable for you and your family throughout the winter months.

With that being the case, it’s important to make sure that you’re on the lookout for any early warning signs that might indicate furnace trouble so you can get a professional in and get the repairs you need before your system fails. To help you in identifying exactly what these are, our team of Wisconsin Rapids HVAC contractors have taken the time to put together this short list highlighting several signs that might indicate your furnace is struggling. This will help decide when to make the call to a professional and get the furnace repairs you need right away.

Unusual Noises

Like any other appliance, your furnace is going to make noises while in use from time to time. That said, it’s a good idea to familiarize yourself with the types of noises that are common for your unit to better identify when something sounds off.

If you begin to hear any strange and sudden noises that you’ve never noticed before, like groaning, banging, or any whining, it can be an indicator of several issues. These issues range from an unbalanced belt to an air leak, an ignition issue, or it could be a sign that some part of your system needs to be replaced. If you hear any strange new noises coming from your home's furnace, the best thing to do is call in a professional HVAC technician right away and have them give your system a full inspection to identify exactly what the issue is and the best way to resolve it.

You Aren't Getting Warm Air

Anytime you go to turn up your furnace dial and you notice that you either aren't getting as much warm air as you should, or you aren't getting any at all, it’s a clear sign that you’ve got a problem on your hands. A lack of heat could be an indicator of multiple different issues, especially if your system still sounds like it's running but just isn't pumping out any warm air.

A lack of warm air could be due to a malfunctioning thermostat, leaking ducts, or even an issue with your pilot light. Whatever the case may be, it’s important to call in an HVAC specialist and get to the bottom of the issue quickly so you can restore your home to the right level of comfort and prevent any further wear on your furnace.

Yellow Pilot Light

When your furnace is functioning properly, your pilot light should have a blue flame. If your pilot light flame is yellow, it’s usually a sign that there’s an issue in your combustion process and your system might be producing carbon monoxide. Carbon monoxide leaks can be deadly, and they aren't something you want to take any chances with. Take a peek at your pilot light every so often during the winter months, and if you notice that your flame has gone from blue to yellow, make the call to your trusted HVAC technician immediately so they can inspect and correct the issue.
