Surge protectors are a great investment to protect your HVAC equipment.

What is a surge? A surge is a transient electrical fluctuation that happens in a fraction of a second and can cause serious damage to highly vulnerable electric equipment in your HVAC system such as your compressor/condenser, controls, thermostat etc.

What are the causes of surges? Both lightning strikes and local power utility “spikes” can enter your business or home through electrical wiring and attack any components that are connected to them. In Douglas, Lane and Coos counties and the surrounding areas, lightning is not a common occurrence but we often get dips, brown outs, and surges in our power. All of this can harm and shorten the life span of your HVAC equipment. On top of this, the local power companies have been deregulated and that is increasing the problems associated with electrical power quality. The same wiring infrastructures that produce and deliver the power to you HVAC equipment are the same pathways that can destroy these investments. It is also important to know that electrical equipment manufacturers  do not cover lightning strikes or other surges under warranty.

How can you prevent it? First, you need to understand that sometimes nothing you do will prevent equipment damage when lightning makes a direct hit. However, most of the time, you can prevent or at least minimize the damage that occurs by installing quality surge protectors. The proper installation and use of these devices will remove will remove the daily power surges and spikes from the local power utility companies, provide protection from lightning strikes, and increase the life of your equipment as well.
