Beat the Heat: Essential Standby Generator Maintenance to Keep Your Texas Home Powered Through Scorching Summer Heat Waves
When Texas temperatures soar above 100 degrees and the power grid strains under peak demand, your standby generator becomes a lifeline for your family’s comfort and safety. But like any critical home system, generators require regular maintenance to perform reliably when you need them most—especially during the brutal heat waves that regularly challenge North Texas communities.
Why Heat Wave Preparedness Matters in Texas
Summer temperatures in North Texas are frequently over 100 degrees, with dangerous heat waves that strain the power grid and exacerbate health problems. Challenges from heat waves or cold snaps cause stress on the grid, which can lead to outages. When ERCOT issues conservation alerts and rolling blackouts threaten your neighborhood, a properly maintained generator ensures your air conditioning keeps running, your refrigerated medications stay cool, and your family remains safe.
Heat-Specific Generator Maintenance Challenges
Texas heat creates unique maintenance challenges that homeowners must address proactively. At around 104 degrees fahrenheit, many diesel generators must be derated, or operated at a lower output level than their rated maximum. Safeguarding your standby or continuous generator during extreme heat is important not only for the life of the generator, but to guarantee that performance is not affected.
Hot weather intensifies several maintenance concerns:
- Air Filter Contamination: Hot, dry months mean dust (even from as far away as Africa at this time of year), and dust means clogged air filters and fuel filters, which mean more wear and tear on your diesel generator as it has to work harder to put out power.
- Battery Performance: The terminal connections also need to be checked to ensure they’re tight, as loose connections can generate excess heat, which is the last thing you want in the summer!
- Cooling System Stress: Insufficiently lubricated bearings can cause your generator to fail in the heat.
Your Pre-Heat Wave Maintenance Schedule
Be sure to design your generator maintenance schedule at the beginning of hurricane season (August to October), and winter weather season (late October to early March). For example, scheduling your bi-annual professional technical visits in late March/early April and late September/October will ensure that your backup generator is at full operational capacity for each of these trouble seasons.
Monthly Tasks (April through September)
In the hotter months, consider switching to weekly exercising to ensure everything is working well. During peak summer months, increase your attention to:
- Weekly exercise runs instead of monthly
- Visual inspection of air intake areas for debris
- Battery terminal inspection and cleaning
- Coolant level checks
Semi-Annual Professional Service
Recommended professional service frequencies for a diesel generator will depend on its usage and run time. As a general guide, you should aim to perform a complete preventative inspection and service on your generator once every 6 months or every 400 hours of operation.
Professional maintenance should include:
- Replace the air filter. Replace the fuel filter. Replace the generator oil and oil filter. Replace the spark plugs.
- Make sure there is the correct concentration of coolant. If necessary, flush the entire cooling system.
- Load bank testing is a critical part of preventive maintenance that verifies your generator can perform reliably under real-world electrical loads. Rather than waiting for a power outage to discover performance issues, this controlled test safely simulates full-load conditions to uncover hidden problems such as overheating, fuel system weaknesses, or battery failures.
Summer-Specific Maintenance Tasks
Either try to schedule your annual load bank test for the summer, or move to a biannual schedule, with one test in summer and one in winter. This ensures your generator can handle full electrical loads during peak cooling season when your air conditioning system demands maximum power.
Professional vs. DIY Maintenance
For all standby generator maintenance, it is important to follow the manufacturer’s recommendations. Proper maintenance should only be performed by trained and qualified personnel. While homeowners can perform basic visual inspections and keep the area around their generator clear, cleaning the fuel and oil filters are more complicated and probably best left to professionals, but they’re also important to keep your unit at optimal performance levels.
