Generator Installation and Repair in Spokane, WA

When a winter storm takes out power in Spokane, you lose more than the lights. A gas furnace still needs electricity to run its blower and controls, so a long outage in January quickly becomes a no-heat emergency. When a windstorm swept through the region in December 2025, around 80,000 Avista customers lost power at the peak, and some waited days for it to come back. Cougar Heating, Cooling, Plumbing & Electrical has licensed electricians who install, repair, and maintain standby generators so your home keeps running when the grid doesn’t.

Why Homeowners Need a Backup Generator

A backup generator repair keeps the systems that matter most running during an outage:

  • Heat. Furnaces, heat pumps, and boiler circulators all need power to operate.
  • Pipes. A cold house in a multi-day outage puts pipes in crawlspaces and exterior walls at risk of freezing.
  • Water. Homes on wells in Mead, Chattaroy, Clayton, and rural North Idaho have no water without power to the well pump.
  • Sump pumps during late-winter snowmelt.
  • Medical equipment, refrigerators, and home offices.

Portable generators can cover a few essentials, but a permanently installed standby generator starts automatically within seconds and can power your whole home. Not sure which fits? Our licensed electricians will help you compare. If you use a portable unit, keep it well away from the house and make sure your carbon monoxide detectors are working.

Generator Installation Process

  1. Load assessment. We list what you want powered and calculate the size you need, including the startup surge from motors like your furnace blower or well pump.
  2. Fuel source. Natural gas where service is available, or propane for homes without a gas line.
  3. Placement. The unit goes on a level pad with proper clearance from windows, doors, and vents, above typical snow depth.
  4. Transfer switch. An automatic transfer switch disconnects your home from the utility before the generator powers it. This prevents backfeeding, which can injure utility crews working on the lines.
  5. Permits and inspection. We pull the required permits and schedule inspection.
  6. Startup and walkthrough. We test the system under load and show you how it works.

Standby generator cost depends on the unit’s size, the fuel type, how far it sits from your gas line and panel, and whether your panel needs an upgrade. You’ll get upfront pricing after the load assessment, before any work begins.

Older or full electrical panels sometimes need a panel upgrade first. Many homeowners also add whole home surge protection at the same time.

Generator Repair & Maintenance

A generator that hasn’t run since last winter may not start when you need it. Call us if yours:

  • Fails its weekly self-test or won’t start
  • Shows a fault code or warning light
  • Runs rough, surges, or shuts down under load
  • Starts, but the transfer switch doesn’t engage

Annual maintenance before winter covers oil and filters, battery testing, a transfer switch check, and a load test. You get upfront pricing before any repair begins.

Generator Installation and Repair in Spokane, WA FAQs​

It depends on whether you want to power the whole house generator or just essential circuits. We calculate your actual load, including motor startup surges, before recommending a size.
Natural gas offers continuous fuel where Avista service is available. Propane works well for rural homes and stores indefinitely, though you’ll want a tank large enough for a multi-day outage.
Yes. Permanent standby generators require permits and inspection. We handle both as part of the installation.
No. Backfeeding through an outlet is dangerous for you and for utility workers. Use a transfer switch or interlock, never run a generator in a garage or near windows, and keep working carbon monoxide detectors on every level.
A generator keeps power on, but it doesn’t stop voltage spikes. Pair it with whole home surge protection for full coverage.
