5 Signs Your Furnace Needs a Tune-Up

May 1

Furnace acting up? Don’t wait for it to break down in the middle of a cold snap. Regular tune-ups keep your HVAC system safe and efficient, but how do you know when it’s time to call in the pros?

Here are five signs your furnace needs some TLC.

1. Unexpected Spikes in Energy Bills

If your usage hasn't changed but your bill has gone up, your furnace could be losing efficiency. This often happens when filters are dirty, parts are worn out, or airflow is restricted.

2. Inconsistent Room Temperatures

Does one room feel like a sauna while another is freezing? Your furnace may be struggling to distribute heat evenly due to duct issues, clogged filters, or aging components.

3. Weird Noises or Odors

Clanks, bangs, rattles, or musty smells are red flags. These can signal loose parts, ignition issues, or even mold in your ducts.

4. Frequent Cycling

Short cycling (turning on and off frequently) can mean the heat exchanger is overheating or your thermostat isn’t working correctly. Both reduce efficiency and add wear and tear.

5. It’s Been Over a Year Since Your Last Tune-Up

Even if everything seems fine, annual tune-ups are crucial. They prevent breakdowns, improve efficiency, and keep your warranty intact.
