Short answer: A whole-home surge protector mounts at your panel and limits voltage spikes before they reach your AC, appliances and electronics; a standby generator keeps selected circuits running during an outage. Call 602-835-5455 and we'll connect you with an independent contractor who installs both in Maricopa.
Is a whole-home surge protector worth it in Arizona?
For many Maricopa homes, yes. Monsoon season brings lightning and utility switching surges, and modern AC systems, pool pumps, appliances and EV chargers all contain sensitive electronics. A panel-mounted surge protective device (SPD) is the first layer; plug-in surge strips at TVs and computers are the second. Current electrical codes also require surge protection when a home's service is replaced or upgraded, so it often gets added during a panel upgrade.
Standby and portable generators
- Standby generator: permanently installed, starts automatically through a transfer switch. Needs a fuel supply, a pad and a permit.
- Portable generator with an inlet and interlock: a lower-cost way to power essential circuits safely. Never backfeed a house through a dryer outlet.
- Battery backup: often paired with solar; quiet, no fuel, sized to the circuits you want to keep on.
Generator installs that involve a gas line also need a licensed gas contractor; the electrical contractor handles the transfer switch and wiring.
Choosing what to back up
Most households pick a short list of essential circuits: refrigerator, some lighting, internet, a few outlets, and sometimes the air handler. Backing up central AC in an Arizona summer takes a much larger generator or battery system, so decide early whether that's a must.
Frequently asked questions
Does a whole-home surge protector protect against a direct lightning strike?
No device can promise that. It limits the far more common surges from nearby strikes and utility switching.
How long does a surge protector last?
SPDs wear with each surge they absorb. Many have an indicator light; check it after major storms and replace the unit when it shows a fault.
Do I need a permit for a generator?
Yes. Permanently installed generators and transfer switches need electrical permits, and gas connections need their own.
