How To Troubleshoot An Overheating Furnace?

January 27, 20244 min read

A furnace is an integral part of your home's HVAC system, working tirelessly to warm the air in your home, circulating it, and maintaining a cozy environment for you and your family. While a furnace is designed to handle heat, like all machines, it has its limits.

Pushing your furnace beyond these limits could lead to overheating, causing several problems and disrupting your home's heating equilibrium.

An overheated furnace is more than just a nuisance; it is a serious problem. In most cases, an overheating furnace will automatically shut off, leaving your home uncomfortably cold. Furthermore, the furnace would likely have sustained severe damage by the time it reaches this stage, necessitating emergency furnace repair.

In this comprehensive guide, we'll delve into the telltale signs that your furnace is overheating, and how you can troubleshoot these issues. We'll also discuss the steps to take when you need furnace repair in Vancouver, Burnaby, Surrey, Coquitlam, Langley, Maple Ridge, Port Moody, Richmond, British Columbia, and what actions you should take if the furnace continues to malfunction.

Identifying The Symptoms of an Overheating Furnace

Your furnace may give off certain signals when it's overheating or on the brink of overheating. Being vigilant and responding to these early warning signs can save you from a heating disaster in the cold months. Let's take a look at some of these symptoms:

Factors that you can observe in your furnace to identify overheating problems - Ariana Heating & Air Conditioning Ltd

Burning Odor

If you notice a burning scent that's not the typical smell of dust being burnt off when you first turn on your furnace in the fall, you might have a problem. This burning smell could indicate that your furnace is overheating, possibly due to a blocked filter.

Humming Noise

If your furnace is making a humming sound, it could be a sign of a problem with the blower motor. If the blower motor isn't functioning properly, the furnace won't be able to disperse heateffectively, leading to complications. Other noises could also indicate that your furnace is on the brink of overheating.

Furnace Shuts Off

If your furnace shuts off and then fails to turn back on, even when the temperature in your house dips below the set temperature on your thermostat, it's likely that your furnace may have overheated.

Understanding these common furnace problems can be less intimidating once you know how to identify potential issues and understand the steps required for furnace troubleshooting. Armed with this knowledge, you can save time and money by knowing when to seek professional help and ensure that your home stays warm and comfortable this winter.

Steps To Troubleshoot An Overheating Furnace

If you suspect that your furnace is overheating, a quick reset might help you troubleshoot the issue. Here's how you can reset your furnace:

Frequently Asked Questions

Need Help? Find Quick Answers to Common HVAC Concerns

Q: Do I Need to Cover My Heat Pump in the Winter?

No, covering your heat pump during winter is not recommended. These units are designed to operate in all weather conditions, and covering them can restrict airflow and cause moisture buildup, potentially damaging the system. 

Q: How Can I Find the Unit Size That Matches My House?

Determining the appropriate HVAC unit size depends on factors like your home’s square footage, insulation quality, number of windows, and more. A detailed load calculation by professionals can help identify the right unit size for optimal comfort and efficiency. 

Q: Is It Safe to Plant Shrubs or Flowers Around an Outdoor Unit?

While landscaping can enhance aesthetics, it’s important to maintain at least a two-foot clearance around the outdoor unit to ensure proper airflow and ease of maintenance. Regular trimming is advised, especially in areas with rapid vegetation growth. 

Q: Should a Thermostat Be Set to the “Auto” or “On” Position?

Setting the thermostat to “Auto” is generally recommended for energy efficiency, as the fan operates only when heating or cooling is needed. However, the “On” setting can provide continuous air circulation, which may be preferred for consistent airflow and filtration. 

Q: What Do Rating Numbers Mean?

HVAC systems have efficiency ratings like SEER (Seasonal Energy Efficiency Ratio) for air conditioners and heat pumps, and AFUE (Annual Fuel Utilization Efficiency) for furnaces. Higher ratings indicate better energy efficiency, leading to cost savings and environmental benefits. 

Q: What Does AFUE Stand For?

AFUE stands for Annual Fuel Utilization Efficiency, representing the percentage of fuel converted into usable heat by a furnace. A higher AFUE rating signifies a more efficient furnace. 

Q: What Is the Difference Between a Split System and a Package Unit?

A split system consists of separate indoor and outdoor units, commonly used in residential settings. A package unit combines both components into a single outdoor unit, often used in commercial applications or homes with limited indoor space. 

Q: What Does SEER Stand For?

SEER stands for Seasonal Energy Efficiency Ratio, measuring the efficiency of air conditioners and heat pumps. A higher SEER rating indicates greater energy efficiency. 

Q: What Is HSPF?

HSPF stands for Heating Seasonal Performance Factor, assessing the efficiency of heat pumps in heating mode. A higher HSPF rating denotes better energy efficiency.
