Generator Maintenance Checklist for Tacoma Homeowners 

A functioning whole-home generator is essential to the safety and comfort of homeowners in Tacoma, Washington. With unpredictable weather and the chance of severe storms, a standby generator can be a lifesaver.  

Keeping your generator in working condition requires regular maintenance. Luckily, we’re going to provide a generator maintenance checklist so you can be prepared for the next power outage. This guide will share five generator upkeep tips for Tacoma homeowners, along with a seasonal maintenance schedule and more home comfort tips 

Why Generator Maintenance Matters in Tacoma’s Weather 

Tacoma, Washington, sometimes sees inclement weather such as severe storms that lead to power outages. Whole-home generators are essential to keeping you and your family safe and comfortable during a storm.

When the power goes out, a whole-home generator can restore power to lifesaving medical equipment, your refrigerator, your HVAC system, and more.  

Tacoma generator maintenance ensures your whole-home generator is ready to kick in when needed. Neglecting maintenance can result in system failure, leaks, electrical issues, and costly repairs.  

 Tacoma’s unpredictable weather means that your generator should be ready to do its job at all times, especially during the winter. Maintain your generator’s efficiency and effectiveness by following this winter generator checklist.

Step 1: Inspect Fuel Quality, Fuel Lines, and Storage 

First, you’ll want to check the fuel system for quality, quantity, and signs of degradation. Cold temperatures often thicken fuel, making it less efficient. This weakens the generator’s overall performance. Be sure your fuel is fresh, stabilized, and stored properly.  

Look for cracks, leaks, and brittleness in the fuel lines to confirm they are secure. Ensure your generator has an adequate supply of fuel and that it is winter grade, if using diesel.  

Step 2: Check Oil Levels and Look for Leaks 

Next, check to make sure that the cold hasn’t thickened your generator’s oil supply. Use the dipstick to check the oil level and fill it up if it’s running low. Be sure to use the manufacturer-recommended oil type for cold temperatures for the best results.  

When inspecting the oil, look for leaks around gaskets, seals, and the oil filter. Small leaks can lead to big problems, especially in the wintertime. Prevent engine damage or shutdowns during freezing weather by addressing any leaks immediately.  

Step 3: Test the Battery, Cables, and Electrical Connections 

Winter’s low temperatures can be tough on batteries. Check your battery health and charge level before the winter season. Inspect battery cables for signs of corrosion, fraying, or loose connections.  

Clean buildup with a battery-safe cleaner. Look for discoloration, exposed wiring, or wear that could impact your generator’s performance. Tighten electrical connections for reliable cold weather operation.  

Step 4: Inspect Coolant, Airflow, and Outdoor Placement 

Check your generator’s coolant levels and top them off, if needed. Ensure the coolant mixture is appropriate for freezing temperatures to prevent damage to internal components.  

Then, inspect vents, intakes, and exhaust paths for blockages or debris to ensure proper airflow. Clear any snow, ice, or debris from these areas to allow air to flow freely. When these areas are blocked, shutdowns and overheating can occur.  

Also, confirm that the generator has enough space for air to circulate around it.  

Step 5: Run a System Test and Monitor Output 

After you’ve inspected the major components such as the battery, fuel, oil, and coolant levels, perform a full system test to confirm it’s ready for winter use. Start the generator and let it run long enough for it to reach its normal operating temperature. Listen for unusual sounds, monitor vibrations, and check that gauges and lights show normal readings.  

Verify that the generator produces the correct voltage and frequency when running. Pay attention to any fluctuations in power output as they can indicate underlying issues that should be addressed promptly.  

Seasonal Maintenance Schedule for Tacoma Homeowners 

Now that we've shared the generator maintenance checklist, let’s discuss when to provide backup generator care.  

Tacoma’s climate brings a mix of rain, windstorms, freezing temperatures, and occasional snow. Following a seasonal generator maintenance schedule ensures your unit is ready year-round. Here’s a seasonal maintenance guide for your whole-home generator.

When to Call a Professional Generator Technician 

Many seasonal maintenance tasks can be performed by homeowners. However, some issues require an expert generator technician. Calling a professional ensures that issues are handled promptly and safely.  

Contact a professional if you notice:  

  • Strange noises or smoke
