The winter months are still hanging around, and you need your furnace to keep your home warm and cozy.

Your home needs to stay warm for your comfort, so the last thing you’d want is to have your furnace go cold and leave you wondering what went wrong.

Sometimes the warning and signs are not obvious. But paying close attention to your furnace’s performance will prevent a potential breakdown. Here are some signs you need a furnace tune-up.

Signs you need a furnace tune-up

Here are signs to look out for so you can prevent furnace breakdowns from happening –

Poor heating ability

A furnace is meant to provide your home with adequate amounts of heat. When this is not the case, there has to be something wrong with the furnace. Check the thermostat. A defective thermostat could be the reason for poor heating in the house, and a sign you need furnace maintenance


Noisy furnace

When you notice loud or unusual sounds coming from your furnace, it’s cause for concern. It could be as a result of a loose belt, or an ignition issue when it sounds like a bang, clang, or clatter. No matter its frequency, you should get it checked out and serviced right away.


Poor air quality


Beyond the noise, your furnace could have a faulty filter. Less circulation of air in your system can result in poor quality air that can affect your breathing. When you notice this in your home, it might be time you looked into furnace maintenance and getting the filters cleaned out or replaced.

Carbon monoxide leaks

Most gas-powered furnaces release carbon monoxide as a byproduct of the combustion process. However, it’s safely contained within the walls of the heat changer and directed through the furnace’s pipe and out of your home.
This becomes a problem when a leak from the furnaces releases this deadly gas into the air. Carbon monoxide detectors can notify you of this. If this happens, get everyone outside and call the experts ASAP.

Strange smells

The smell of gas or oil is a rather bad sign here, especially when it’s recurrent. It could be a sign of leaking fuel, which is a serious fire hazard. Get furnace maintenance immediately.

Yellow pilot light

There’s a lighting guide that shows the condition of the balance of air and gas in your furnace. The blue pilot light is an indicator that the furnace is running ideally. On the other hand, a yellow light is a case of improper balance of gas. If you notice this, then it’s time for a furnace tune-up.

Increase in gas cost

If your gas bill rises above its normal cost, it could be a result of your furnace consuming more gas to sustain its performance.

An increase in your energy consumption and a simultaneous increase in your energy bills is almost always a consequence of an HVAC component working twice as hard to do its job.

Get the problem fixed to prevent further damages and save yourself a ton of money.

Waiting for warnings before taking steps to act on furnace tune-up can be risky. Preventative maintenance is your best bet to avoid the chances of this happening.

However, if something goes wrong, the above signs should notify you of imminent danger. Recognizing these signs early enough can help you stay safe and warm.
