When winter storms roll through Wynnewood and Villanova, your standby generator becomes your home's lifeline. Cold temperatures, ice, and snow can strain your generator just when you need it most. The good news? A little preparation now means reliable backup power when the lights go out.
Don't wait for the next winter storm to test your generator. Contact Power Watch Systems today at (610) 890-7693 or schedule your inspection online to ensure your system is ready when you need it most.
Why Winter Maintenance Matters
Your standby generator sits outside year-round, quietly waiting for its moment. Winter presents unique challenges that can prevent your unit from starting or running properly during an outage.
Cold weather affects generators in several ways. Engine oil thickens in freezing temperatures, making it harder for your generator to start. Batteries lose power faster when it's cold. Snow and ice can block vents or damage components. Without proper preparation, you might find yourself in the dark during a winter power outage, wondering why your backup system failed.
Regular maintenance keeps your generator reliable. Think of it like preparing your car for winter—you wouldn't skip an oil change or tire check before the first snowfall. Your generator deserves the same attention.
Clear the Area Around Your Generator
Your generator needs breathing room to operate safely and efficiently. Before winter arrives, take a walk around your unit and assess the surrounding area.
Start with these essential clearance tasks:
- Remove leaves, branches, and debris within three feet of the generator
- Trim back any bushes or plants that have grown too close to the unit
- Check that gutters and downspouts don't direct water toward your generator
- Ensure the area has proper drainage to prevent ice buildup
Snow management is critical during winter months. After storms, gently clear snow away from your generator using a broom or soft brush—never use sharp tools that could damage the unit. Keep pathways to your generator clear so technicians can access it if needed. If heavy snow is forecast, consider building a simple shelter or canopy that provides overhead protection while maintaining proper ventilation. Never fully enclose your generator, as it needs airflow to operate safely.
Inspect and Clean Key Components
A thorough inspection catches small problems before they become big headaches. Even if you schedule professional generator services, knowing what to look for helps you spot issues early.
Begin with a visual check of your generator. Look for cracks in the housing, loose wires, or signs of rust. Check all vents and louvers to ensure they're free of obstructions. Examine hoses and connections for wear or damage. If you notice anything unusual, take photos and contact a professional.
Pay special attention to these components:
- Air intake and exhaust vents—brush away dirt and debris
- Cooling system—look for leaks or damage to the radiator
- Fuel lines—check for cracks or loose connections
- Control panel—ensure buttons and switches work properly
- Weather-resistant housing—repair any damaged seals
Don't forget your battery. Cold weather is tough on batteries, and a dead battery is one of the most common reasons generators fail to start. Check battery terminals for corrosion (that white, crusty buildup). Clean terminals with a wire brush if needed. Test the battery charge—most auto parts stores will do this for free if you disconnect and bring it in.
Schedule Professional Maintenance
While homeowners can handle basic upkeep, professional maintenance ensures your generator is truly ready for winter. Trained technicians have the tools and expertise to spot issues you might miss.
Professional maintenance typically includes changing the oil and filters, testing the battery and charging system, inspecting the transfer switch, running diagnostic tests, and checking fuel quality and lines. If your generator hasn't been professionally serviced in the past year, now is the time.
Most manufacturers recommend annual maintenance at minimum. If your generator runs frequently or is older than five years, twice-yearly service provides extra peace of mind. Fall is the ideal time for your pre-winter checkup—before the first big storm but when technicians' schedules aren't yet packed with emergency calls. Power Watch Systems can assess your system's condition and address any concerns before winter weather arrives.
Test Your Generator Monthly
Regular testing keeps your generator ready and helps you catch problems early. Many modern generators include automatic exercise cycles that run the unit weekly for a few minutes. This feature prevents fuel from going stale and keeps components lubricated.
Even with automatic exercise, run a full test monthly. Here's how:
- Turn off several circuits in your home
- Manually start your generator using the control panel
- Let it run under load for at least 30 minutes
- Listen for unusual noises or vibrations
- Check that your selected circuits receive power
- Verify the generator shuts down properly
During your test, watch for warning lights on the control panel. Note how quickly the generator starts and whether it runs smoothly. If anything seems off—strange sounds, slow starting, or irregular running—call for service right away.
Protect Against Fuel Issues
Fuel problems are a leading cause of generator failure. Cold weather makes these issues worse, so addressing fuel concerns before winter is essential.
For natural gas generators, your fuel supply is generally reliable. However, have a technician verify that gas pressure is adequate and connections are secure. If you have a propane generator, check your tank level well before winter. Propane doesn't evaporate in cold weather like many people think, but very cold temperatures can affect vapor pressure. Keep your tank at least half full throughout winter, and consider a tank gauge if you don't have one.
Diesel generators require extra attention in winter. Diesel fuel can gel in freezing temperatures, preventing your generator from starting or running. Add a winter fuel additive designed to prevent gelling. Store diesel fuel properly and rotate it regularly—diesel has a shelf life of about 12 months under ideal conditions, less in varying temperatures.
Consider a Winter Weather Package
Some generators benefit from additional cold-weather protection. If you experience harsh winters with temperatures regularly dropping below 20 degrees Fahrenheit, these upgrades help ensure reliable operation.
A block heater keeps the engine warm, making cold starts easier and reducing wear on components. Cold-weather batteries are designed to perform better in freezing conditions. Some homeowners add a generator tent or shelter for extra protection—just remember that proper ventilation is non-negotiable for safe operation.
If your generator is exposed to severe weather or you've experienced starting problems during cold snaps, ask about these options during your next repair or warranty service visit.
Know When to Call for Professional Help
Some generator issues require professional expertise. Don't wait until a winter storm leaves you in the dark to address these warning signs.
Contact a technician if your generator:
- Fails to start after several attempts
- Runs roughly or makes unusual noises
- Produces visible smoke or exhaust inside the housing
- Shows error codes on the control panel
- Leaks fuel, oil, or coolant
- Fails to transfer power to your home
Strange odors, frequent shutdowns, or rust on critical components also warrant professional inspection. If your generator is more than ten years old and hasn't been evaluated recently, a comprehensive assessment helps you understand its remaining lifespan and whether generator installation of a newer model makes sense.
Create a Winter Emergency Plan
Beyond maintaining your generator, having a winter preparedness plan gives you confidence during storms. Keep a flashlight and basic tools near your generator in case you need to clear snow or check on it during an outage. Store your generator's manual and warranty information in an easy-to-find location. Save your generator service company's phone number in your phone.
Make sure everyone in your household knows where the generator is and how to recognize if it's running properly. While operating a generator should be left to adults, even children should know what the generator sounds like when it's working correctly.
Consider what happens if your power goes out for an extended period. Do you have enough propane or can your natural gas supply sustain your generator for several days? What appliances will you prioritize? Thinking through these scenarios now prevents stress during an actual emergency.

Winter in Pennsylvania brings beautiful snow and cozy evenings—but it also brings power outages. Your standby generator is a significant investment in your home's comfort and safety.
