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 asset 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.

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

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 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. Damage by lightning is not usually covered by your HVAC system warranty. 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.
