Complete Generator Services
Whole-home standby generator installation including site assessment, load calculation, electrical and mechanical setup, integration with transfer switch, and load bank testing. Automatic — starts within seconds of an outage.
A transfer switch safely connects your generator to your home’s electrical system. We install both manual and automatic transfer switches — required for safe generator use and code compliance.
We calculate exactly how much power your home needs during an outage and help you choose the right generator size — from covering essential circuits to whole-home power.
Routine inspections, fluid checks, battery testing, lubrication, and load testing to keep your generator ready when you need it. Maintenance plans available.
24/7 emergency generator repair service. Rapid diagnostics, on-site repairs, component replacement, and temporary power solutions for longer service needs. Our certified techs restore power fast.
Simulated load testing confirms your generator performs under real conditions — critical for standby generators to prevent wet stacking and verify it can handle your full electrical load when it counts.
What Seattle Homeowners Say
We lost power for three days during a winter storm and decided enough was enough. Day & Nite installed a Generac standby generator and now when the power goes out, we don’t even notice. Worth every penny.
Day & Nite handled everything — the permit, gas line hookup, electrical panel connection, and transfer switch. The technician was professional and kept me informed through every step. Generator works perfectly.
My generator failed during a storm. Called Day & Nite at 11pm and a technician was at my house within two hours. Had it repaired and running before midnight. Outstanding emergency service.
