Whole-Home Surge Protection in Ankeny & Des Moines, IA
A voltage spike travels at the speed of electricity. By the time a surge enters your home's wiring, the damage to connected devices has already begun. The HVAC control board that fails without apparent cause three days after a thunderstorm. The smart home hub that starts behaving erratically. The appliance that simply stops working. These are often surge casualties — and they are invisible until the bill arrives.
Whole-home surge protection installs at the electrical panel and intercepts excess voltage before it reaches your circuits. 72 Degrees' licensed electricians install panel-level surge protection for homeowners across Ankeny, Des Moines, Johnston, Waukee, Grimes, and the Central Iowa area. All installations are backed by our satisfaction guarantee.
How Whole-Home Surge Protection Works
A panel-mounted surge protector uses metal oxide varistors (MOVs) to clamp voltage above a safe threshold, absorbing or redirecting the excess energy before it travels down your circuits. Unlike power strip surge protectors — which protect individual devices but provide no coverage for hardwired systems or devices plugged elsewhere — a whole-home device creates protection at the point of entry into your home.
Every circuit in the home draws power through that protected service: your furnace, your air conditioner, heat pump, water heater, refrigerator, sump pump, washer, dryer, and every outlet. A power strip on one appliance cannot accomplish that.
Why Iowa Homeowners Need This More Than Most
Iowa averages over 40 tornadoes per year and ranks among the top states nationally for severe thunderstorm frequency. The Des Moines metro — and the Ankeny, Johnston, and Waukee corridors specifically — experiences multiple significant storm events annually from late April through September. Lightning strikes on nearby infrastructure are among the most destructive surge sources, capable of generating tens of thousands of volts on the power line before the energy reaches your home.
The August 2020 derecho that crossed Iowa from west to east caused widespread power outages across Polk County and the metro, with MidAmerican Energy restoration taking days in some areas. Surge events associated with that storm — both during the event and during power restoration — caused equipment damage throughout the area. Panel-level protection provides meaningful defense against this class of event.
Beyond storm-related surges, internal surges from large appliances cycling on and off are cumulative and constant. Your central air conditioner starting on a July afternoon, your refrigerator compressor cycling — each event is small, but over years they degrade electronics and shorten appliance life. Panel protection addresses both categories.
Surge Protection and Generators
If you're also considering a whole-home standby generator, surge protection is a natural companion installation. Generator startup and utility power restoration after an outage are both moments when voltage irregularities occur. Having panel-level surge protection in place means your systems are protected during reconnection events as well as normal operation.
Frequently Asked Questions
How much does whole-home surge protection cost in Ankeny, Iowa?
Whole-home surge protection installation is one of the more accessible electrical upgrades in terms of investment relative to protection provided. 72 Degrees provides upfront pricing before any work begins. The installation is typically completed in one to two hours. Contact us at (515) 965-7272 or 72degrees.com/contact for current pricing.
What is the difference between a whole-home surge protector and a power strip?
A power strip protects only the devices plugged directly into it. A whole-home panel-mounted device protects every circuit in the home simultaneously — including hardwired appliances, your HVAC systems, and everything plugged into every outlet. The two work best together: panel protection handles large surge events from outside; device-level protection provides a secondary layer for sensitive electronics at individual outlets.
Will surge protection cover a direct lightning strike?
Whole-home surge protection significantly reduces damage risk from nearby lightning strikes that induce voltage on the power line — the most common scenario in Central Iowa. A direct strike to your home or service entrance can exceed the capacity of any surge device. What surge protection reliably defends against is the much more frequent scenario: nearby strikes, utility grid switching events, and storm-related power quality disturbances.
How often does a whole-home surge protector need to be replaced?
MOVs degrade with each surge they absorb. Most quality devices include a status indicator showing when protection capacity has been depleted. Typical service life is 5 to 10 years under normal conditions, though a home in a high-lightning area or one that has experienced multiple significant surge events may need replacement sooner. 72 Degrees can evaluate your existing device during any service visit.
Will surge protection protect my furnace and air conditioner?
Yes. HVAC control boards are among the most common and costly surge casualties — a furnace control board replacement can cost several hundred dollars. A panel-level surge protector defends the circuits feeding all of your heating and cooling systems against incoming voltage spikes. Given the cost of HVAC control board replacement, protection typically pays for itself after a single avoided event.
Can surge protection be installed at the same time as other electrical work?
Yes, and that is often the most efficient approach. If 72 Degrees is already at your home for a panel upgrade, generator installation, or EV charger installation, adding panel-level surge protection at the same visit saves a service call. Ask about combining services when you schedule.
