Signs of Common Furnace Issues and What’s Causing Them

Your furnace is essential to keeping your home warm and cozy during our uncomfortable, cold winters. When a furnace is working as it should, you’ll hardly even notice how well it’s doing its job. But when issues arise, your furnace will let you know almost immediately. From weak airflow to strange noises, furnace issues can be common this time of year.

As for what’s causing them, a lot of these issues will happen if you’ve neglected routine furnace maintenance. This essential service is an opportunity for our technicians to catch those issues that are brewing before they bubble over and become a major inconvenience.

1. Inadequate Airflow

When your furnace is working properly, you should notice a consistent flow of air through your vents. If it seems like nothing is happening when you turn it on, that’s a major concern because your home isn’t warming up adequately. In most cases, the problem lies with the blower fan. Your blower is responsible for blowing the heated air through the ductwork, so when it’s broken, you’ll notice a lack of air.

The first thing to check is the air filter. If it’s dirty and clogged, this hinders your furnace’s ability to have a strong airflow output. Change the filter and see if that alleviates the problem. If that doesn’t do it, give us a call to schedule service. You don’t want to keep paying for your furnace to run if it can’t deliver heated air to your home.

2. Cold Air Instead of Hot

Just as bad as weak airflow is when the air coming out of the vents is cold instead of hot! A furnace that’s sending cold air into your home could be caused by a number of issues such as an improper thermostat setting, a dirty air filter, a faulty fan limit switch, or something else entirely. Contact us to restore your furnace’s heating output.

3. Short Cycling

Short cycling occurs when your furnace repeatedly turns itself on and off without completing a heating cycle. This can happen for many different reasons. The important thing to know about short cycling is that not only does it keep your home from reaching your desired temperature, but it’s also incredibly hard on the furnace. This is an issue that should be addressed as soon as possible. 

4. Strange Noises

There are just a few sounds you should hear from your furnace: when it turns on and off and the gentle whooshing sound of air coming from the vents. Other than that, a furnace shouldn’t make unusual noises.

Unexpected and sudden noises can be alarming. Some sounds you might hear from a furnace that shouldn’t be ignored include clicking, banging, booming, screeching, humming, and rattling. If you ever hear any of these noises, give us a call for prompt repairs. One of our NATE-certified technicians will be able to locate the source of the noise and fix it.
