Is Your Furnace Overheating? Three Telltale Signs

Dec 27, 2019 | Blog

Without giving it much thought, most people expect their home’s furnace to accommodate them with heat as soon as they need it.

It’s no different than a car, a power tool, or any machine that utilizes an engine to work. A heating system can overheat or sustain severe malfunctions that can ultimately trigger a breakdown. In this blog, we at Delaware Heating & Air will explore a few of the most common causes of heating system problems and failures and what you can do to avoid it and correct the issues that it can lead to.

A furnace that overheats during the dead of a Delaware County winter can quickly become a very uncomfortable circumstance for you and your family. So give us a call if you want fast, affordable expert service.

A Furnace That Turns Off Before Completing a Cycle

This is the most prevalent sign of an overheating furnace. An overheating furnace shuts itself down before completing a cycle. This is actually a safety feature of your system. When it begins to shut off like this, it’s doing so to stop lasting damage. The feature is called a high-limit switch. This switch detects an unsafe temperature and shuts down the furnace. Once this starts, it’ll only get worse without servicing.

Burning Smells

A faint burning smell is common when you turn on your furnace after it’s been off for a long while. But this should only last about a half-hour at most. Burning odors that persist, on the other hand, are a sign of something worse. If the latter is happening and the aroma remains past that opening 30 minutes, don’t delay. Give us a call right away.

Strange Sounds Originating from Your Furnace

Unfamiliar humming noises arising from your heating system typically indicate your motor is overworked. If this is occurring, it means it’s about to shut off. When that happens, we strongly advise you shut off your furnace immediately. If you don’t and you allow this to continue, it won’t be long before it shuts off on its own. If that happens, you’ll find yourself without heat in the frigid cold of a Delaware County winter. You can also avoid this by calling us right away.

Final Reflections

If you learn one lesson from all this, we hope that it’s a realization that you can prevent all the above and lengthen the life of your home’s valuable heating system with one simple preventative action.

What’s that action? Schedule yearly checkups with a certified HVAC professional. Don’t skimp out on the significance of routine maintenance. 

As it is often said in the HVAC world, being proactive with your home’s valuable heating system, rather than being reactive, pays off in dividends. Those who believe they are saving cash by skipping a year or so fail to understand that routine maintenance is a wise investment. Just picture it. How much will a new furnace cost you if your furnace dies prematurely in the severe cold of winter in these parts?

It’s not worth it. So give us a call. We’d love to hear from you!
