What a Power Surge Can Do to Your HVAC System

October 15, 2018

During the summer and fall seasons, thunder and lightning storms are more common in Raleigh, North Carolina. These storms might be exciting to watch from your front porch, but they can create problems in the home. One of these issues could be with your HVAC system, as a power surge can damage some of the components used to heat and cool your home. It’s important to know what to do if a power surge impacts your HVAC system, as well as to understand the risks of continuing to operate the unit.

More Electronic Parts

In the past, a heating and cooling system was more mechanical and had fewer electronic components that could potentially be damaged by a power surge. However, in today’s tech-focused world, just about every modern HVAC system has a number of features designed to improve efficiency and keep air flowing that relies on electrical power. If your power goes out, your system won’t be able to produce heated or cooled air, and those components could get fried as the result of a surge.

Repair or Replace?

If you do experience a power surge at your home, the best thing to do is contact an HVAC technician to take a look inside the unit and determine the extent of the damage. It’s impossible to know exactly what will happen. How much damage your unit sustains will depend on how many electrical components are used, as well as how much power flows through the system during the surge.

You may also wonder whether the heating and cooling system will need repairs or have to be replaced. In many cases, the damage is severe enough that some of the components will have to be replaced. Underlying problems could lead to poor efficiency or cause your system to fail prematurely, which will likely cost more in the long run than having the system fixed when the damage first occurs.
