5 Quiet Signs of a Disgruntled Furnace

Furnaces come in all shapes and sizes, which means that when they’re encountering problems, they display themselves with different symptoms. Sometimes, a furnace will make a booming noise, and other times it will click rapidly as it tries to start up. And sometimes, unfortunately, a furnace will make no noises at all and will work incorrectly until you detect something else.

What kinds of symptoms could be displayed that aren’t sounds? Well, that’s what this blog topic is going to cover. Heating systems are machines that work exactly as well as their parts require them to. Any slight change in how a furnace would ideally or efficiently work, is usually a sign that something is misaligned, broken, or not set up properly.

Our team can help you when encountering this kind of problem. Before you panic, make sure you schedule an appointment for heating repair in Cedar Rapids, IA with our team. Then, we’ll get into the details!

Constant Starting and Stopping

Here’s the first tip that we’ll give homeowners–if your furnace is constantly starting and stopping to the point where you notice it, then we’ve got bad news. Your furnace likely needs repairs, or a least a good filter change.

This likely means that your furnace isn’t able to heat your home to the temperature it’s supposed to, or that the heat is escaping from somewhere so it can’t keep the heat where it should be. Thus, your furnace will continue to run cycles as components get stressed out and break down over time.

Try changing the air filter first and see if that makes a difference. Then, call our team for repairs.

Strange Burner Flame Color

Contrary to some opinions, the flame inside of your gas furnace should be blue. This means that there’s little to no gas escaping from the system, and it’s a good mix of oxygen and gas being burned together in order to create the most heat and a blue flame.

If your burner is running with a yellow flame, it likely means that some of the gas is escaping due to the burner being dirty or gunked up. This can be dangerous, because it means that some gas or carbon monoxide is leaking out into the rest of your system can could be causing trouble for you and your family.


Rust is never a good sign, and it signifies that components are both encountering moisture in the air and have worn down due to old age. If your system is rusting up to the point where it’s looking a lot older than it should, you might want to get the casing fixed or the whole system replaced.

Excessive Moisture

Moisture can be a big problem for a furnace. The water vapors created from burning gas can condense along the vent pipe and cause a leak to occur around the system. If you’re noticing excessive moisture, we’d recommend calling a professional so they can install a water pump or dehumidifier to deal with it.

High Heating Bills

Last but definitely not least, if you notice a trend on your heating bills that you don’t like, that could mean there’s a problem with your furnace. As a furnace gets less efficient and encounters problems, it burns more gas to create the same amount of heat. This means that a higher utility bill could be a sign of a problem.
