Pre-Storm Generator Check
Do not wait for a storm warning to find out your generator will not start. Run this walkthrough before every storm season to confirm your standby system is ready to deploy.
- 1
Verify the generator is in AUTO mode on the main control panel.
- 2
Check the oil level. Generac standby units require oil changes every 200 hours or annually, whichever comes first.
- 3
Inspect the battery. A weak battery is the leading cause of standby failure. Replace every 2–3 years.
- 4
Run a manual exercise. Use the transfer switch test mode to simulate a utility outage. The generator should start, the transfer switch should click over, and power should restore inside 10 seconds.
- 5
Confirm all critical circuits (sump, refrigerator, medical equipment) are on the generator load side.
- 6
Check the propane or natural gas supply. Confirm tank level or confirm the gas line is unobstructed and the isolation valve is open.
- 7
If any step fails, schedule a maintenance visit before the storm season. PM contract clients receive priority scheduling.
Common Questions
Half my house lost power, but my neighbors are fine?
This usually indicates you've lost one "leg" of your incoming phase power, or the main breaker is beginning to physically degrade. Check your main panel for tripped circuits. If none are tripped, contact us immediately for a diagnostic. The grid incoming line may be compromised.
Why does my breaker keep tripping when I use an appliance?
The breaker is doing its job by terminating power before too much heat builds up in the wire. The appliance is drawing more amperage than the circuit is rated for. Do NOT continuously reset it. You need a dedicated high-amp circuit installed.
Do I actually need a Generac system?
If you rely on medical equipment, have sub-pumps that protect finished basements from flooding, or run remote business servers, a Generac is not a luxury. It gives you real peace of mind for your home. It detects grid failure and auto-deploys in 10 seconds.
