Texas leads the nation in lightning strikes. Learn how whole house surge protection works, what it costs and why it protects your HVAC, appliances and electronics.
Texas sees more lightning than almost any other state, and the grid itself produces smaller surges every day. A single event can take out an HVAC control board ($800+), a refrigerator, or every smart device in the house.
A whole house surge protector mounts at the panel and diverts excess voltage to ground before it reaches your circuits. Power strips protect one device; a panel unit protects everything.
Most installs are $350–$750 including the device and labor — usually under two hours of work. Many HVAC warranties now require one.
Best practice is a Type 2 panel protector plus point-of-use strips for sensitive electronics. If you have solar or a battery, surge protection on the inverter side is also recommended.
