Why Surge Protection for Furnace is a Must-Have

As a homeowner, I understand the importance of protecting my investments, especially when it comes to expensive appliances like my furnace. That’s why I made sure to install surge protection for my furnace, and here are the reasons why it’s a must-have.

First and foremost, a furnace is a complex piece of equipment that relies on delicate electronic components to function properly. A sudden power surge can cause these components to fail, resulting in costly repairs or even complete breakdown of the furnace. With surge protection in place, any excess voltage will be redirected away from the furnace, keeping it safe from damage.

Furthermore, power surges can occur due to various reasons such as lightning strikes, faulty wiring or utility company issues. These surges can happen at any time without warning and can severely damage your furnace. By having surge protection installed, I have peace of mind knowing that my furnace is protected 24/7.

Another reason why surge protection for furnace is necessary is that it can save you money in the long run. As mentioned earlier, a power surge can cause significant damage to your furnace which may require expensive repairs or even replacement. By investing in surge protection now, you are preventing potential costly repairs

My Buying Guide on Surge Protection For Furnace

As a homeowner, I understand the importance of protecting my appliances and electronic devices from power surges. One appliance that often gets overlooked when it comes to surge protection is the furnace. A power surge can damage the furnace’s electrical components, leading to costly repairs or even replacement. In this buying guide, I will share my experience and knowledge of purchasing surge protection for furnaces.

Understanding Power Surges

Before diving into the details of surge protection for furnaces, it is essential to understand what a power surge is. A power surge is a sudden increase in voltage that lasts for a short period, usually less than a second. It can be caused by lightning strikes, utility grid switching, or faulty wiring in your home.

The Importance of Surge Protection for Furnaces

The furnace is an essential appliance in any home as it provides warmth during the cold winter months. However, most homeowners do not realize that a power surge can damage the furnace’s electrical components, such as the control board and blower motor. This can lead to malfunctions or complete breakdowns of the furnace, resulting in expensive repairs or replacement costs.

Types of Surge Protection for Furnaces

There are two types of surge protection devices (SPDs) available for furnaces: plug-in SPDs and whole-house SPDs.

  • Plug-in SPDs: These are small devices that plug into a wall outlet and provide point-of-use protection for specific appliances like furnaces. They are affordable and easy to install but only protect one appliance.
  • Whole-house SPDs: These are installed at your home’s main electrical panel and protect all appliances connected to your home’s electrical system. They offer more comprehensive protection but can be more expensive to install.

Factors to Consider When Choosing Surge Protection for Furnaces

When purchasing surge protection for your furnace, here are some factors you should consider:

  • Type of SPD: As mentioned earlier, you can choose between plug-in or whole-house SPDs based on your budget and level of protection needed.
  • Surge Rating: The higher the surge rating (measured in joules), the better the protection against power surges. Look for an SPD with at least 600 joules of surge rating.
  • Certification: Make sure the SPD you choose is certified by a reputable organization like Underwriters Laboratories (UL) or Canadian Standards Association (CSA).
  • Noise Filtering: Some SPDs also provide noise filtering capabilities that help reduce electromagnetic interference (EMI) from other appliances in your home.

Budget Considerations

The cost of surge protection for furnaces varies depending on the type and brand you choose. Plug-in SPDs typically range from $20-$50 while whole-house SPDs can cost anywhere from $100-$500. Remember that investing in good quality surge protection now can save you money in the long run by preventing costly repairs or replacements due to power surges.

In Conclusion

Surge protection for furnaces may not be something we think about often, but it is an essential investment to ensure our home’s comfort and safety. By considering factors such as type, certification, and budget when choosing an SPD, you can protect your furnace from potential damage caused by power surges.
