Key takeaways:
- Ensure your generator can power the things you care about the most.
- Prioritize your oil, fuel, and battery before a cold front.
- Scheduling a professional generator inspection is the safest and most reliable option.
You don’t need to live in North Texas for long before realizing winters can be sneaky. One week you’re grilling, and the next you’re dealing with a frozen driveway and a struggling power grid. Like with Winter Storm Uri in 2021, when homes across Texas went without power for consecutive days because the grid wasn’t prepared for the record-breaking, freezing temperatures.
This means regular generator maintenance in North Texas should be a priority if you want a reliable backup, even if you don’t lose power that often. Use this guide as your practical checklist for completing your home generator’s winter preparation correctly.
1. Inspect Fuel Supply and Storage Conditions
Most generators run on diesel, natural gas, propane, or gasoline. If you have a standby unit connected to a gas line, you don’t need to store fuel yourself, but you should have a professional test the supply lines as part of a proper generator inspection in Dallas.
Propane can last indefinitely if stored outdoors and upright in an approved tank. However, gasoline and diesel have a limited shelf life, so it would be safer to get rid of them rather than risk clogging your engine with old fuel.
2. Test the Battery and Charging System
If your generator won’t start, it’s probably because the battery failed. Cold weather impacts your battery’s performance, so a pre-winter inspection is essential. Confirm that the battery has enough power, and have a technician remove any corrosion (white or green buildup).
For standby units, test your auto-start feature by turning off the main power source and allowing the generator to start automatically. If it delays or doesn’t start at all, the battery or charging system might be the reason. As a general rule, you should replace the battery every 2-3 years, even if it hasn’t failed.
3. Change the Oil and Inspect Filters
Just like a car, your generator also requires oil changes to keep the engine healthy. This is often an overlooked step, but it’s a crucial part of generator maintenance in North Texas. If you haven’t had a recent standby generator service, consider doing both an oil and air filter change.
The most reliable approach for oil selection is to follow your generator’s manual. However, for cold weather, it will usually specify a low-viscosity (thinner) oil, such as 5W-30, to allow for quick flow during startup.
4. Run a Full Load Test
To test if your backup power system is ready for winter, run it under load for 20-30 minutes. This means powering the appliances you would usually use during an outage for at least half an hour and verifying that the generator doesn’t lag or make any unusual sounds or smells.
You should also test your transfer switch. For manual switches, shut off the main power and flip the transfer switch to the generator position, and confirm that power is being supplied. For automatic switches, turn off the main breaker and check that the generator starts automatically.
5. Check Vents, Enclosures, and Electrical Connections
Since generators live outside, it’s no surprise that they’re prone to dust, debris, and even ice buildup. Clear any buildup around the unit (especially the vents) to make sure it has enough airflow to prevent overheating while it runs.
Also, ensure that any weather-resistant enclosures are still intact, and confirm that the wiring and insulation are still in good condition and free from any signs of rodent activity like droppings or chewed wires.
6. Review Your Coverage: What’s Actually Powered?
Many mistakenly believe their generator can power their entire home, but that’s not always the case. In most instances, a generator is only wired to specific circuits. For example, your generator might power your TV and lights, but not your AC or washing machine.
So, you need to decide which appliances you 100% can’t go without. If your current generator setup can’t cover must-haves like medical equipment, HVAC systems, or security systems, it’s time to talk to a licensed electrician about an upgrade.
7. Schedule a Professional Generator Inspection
More complex issues, such as engine misfires, failing sensors, or alternator wear, are difficult to spot without a trained set of eyes and proper tools. Getting a preventative maintenance check is far less stressful (and cheaper) than an emergency repair during an ice storm.
