Power Surges: The Silent Killer of Your Heating and Cooling System

When we think of power surge protection, most people automatically think to protect their expensive electronics and appliances. We seldom think about our air conditioners or furnaces needing the same protection. Your heating and cooling system in your home is a major investment in comfort. Protecting your assets should be equally important and a priority for any homeowner.

What Is A Power Surge?

A power surge is a very brief voltage spike that occurs on power lines, cable, and telephone lines. These surges can occur when something raises the electrical charge flowing into your home’s electrical wiring, affecting the lighting, appliances, and electrical equipment in your home or business. Reoccuring power surges could potentially damage your electronic appliances over time without you even knowing it. It is important to take the appropriate precautionary measures, in order to avoid the possibility of electrical damage.

What Causes Power Surges?

There are many different factors that can cause a power surge. It can be internal or external.

Some of the most common causes of power surges:

  • Lightning and Electrical Storms

  • Faulty or Damaged Electrical Wiring

  • Downed Power Lines

  • Power Outages

  • Large Appliances Cycling On or Off

  • Power Plant Maintenance

  • Bad Electrical Components

  • Aging Electrical Components

  • Overloaded Charging Component

Tennessee may not be the Lightning Capital of the U.S. but we are in the top 10. We see a great deal of lightning activity. Neglecting to protect your furnace, air conditioning or heat pump system from lightning or electrical surge damage can be an expensive repair.

Can A Power Surge Cause A Fire?

Power surges often times last for a fragment of a second; however, they could potentially be dangerous not only to your electronics and precious possessions but to you and your family as well. Power surges can be powerful enough to potentially start a fire. In order to prevent electrical fires from occurring due to power surges, it is best to have a surge protector connected to your appliances.

How To Fix A Power Surge

Your HVAC and electrical appliances can begin getting damaged with a single power surge. Often times, a power surge is out of your control, such as in the case of a lightning storm or a power outage. Your electrical company would be in charge of "fixing" a power surge in such situations. But there are steps you can take to prevent a power surge from causing damage in your home. Overloaded circuits are a prime example of something in your control that could easily cause a power surge and damage your devices and appliances. You can hire electrical experts to separate areas in your home, which have several electronic appliances, into separate circuits.

Can a Power Surge Damage My Heating and Air Conditioning System?

Your HVAC unit has several electrical components which are sensitive to repeated spikes and surges. Even if your air conditioner or heater does not show obvious signs of damage, these surges can cause damage over time by wearing down your system, making replacements necessary years earlier than you were expecting or planning.

An external power surge can result in an immediate breakdown or destroy your unit. Your HVAC system warranty does not usually cover damage by lightning. Many homeowner insurance policies do cover lightning damage; however, the burden to prove lightning was the cause of the damage is on the homeowner.

Why Should I Invest In A Surge Protection For My HVAC Unit?

Your home heating and cooling system is a valuable investment. Surge protection is inexpensive insurance for protecting your home’s comfort. It helps prevent downtime and lowers the risk of expensive repairs. Additionally, surge protection can prolong the life of your central air conditioning system by monitoring incoming electricity and turning it off if there is an electrical surge or spike. The HVAC surge protector absorbs the electrical surge and sends it to the ground.
