Top 5 Reasons to Book Your Generator Tune-Up Before Summer Hits

As the warm weather rolls in and Ontario residents gear up for another summer of barbecues, weekends at the cottage, and backyard get-togethers, one thing often gets overlooked: generator maintenance.

Here at Sparks Generators, we know firsthand how vital a properly maintained generator is—especially during the summer months when storms, high temperatures, and increased demand on the power grid can lead to unexpected outages. Whether you own a Generac generator or another brand, booking a tune-up before summer hits is the smartest way to ensure you're protected when the power goes out.

Here are the top 5 reasons why now is the time to schedule your generator maintenance in Barrie and surrounding areas:

1. Prepare for Thunderstorm Season

Summer in central Ontario means more than sunshine—it also means frequent thunderstorms, heavy rain, and the occasional lightning strike. These storms can knock out power for hours, even days. If your generator hasn’t been serviced since winter, there’s a good chance it may not be ready when you need it most.

A tune-up now ensures:

• Your generator starts reliably during the first outage

• Components like batteries and spark plugs are in working order

• Your fuel system is clean and functional

Being proactive could be the difference between a comfortable evening and a costly power emergency.

2. Prevent Heat-Related Performance Issues

Just like people, machines can struggle in the heat—especially if they haven't been maintained. High summer temperatures can cause generators to overheat or experience fuel vaporization issues, particularly if filters are clogged or fluids are low.

Regular maintenance helps by:

• Checking coolant and oil levels

• Cleaning or replacing dirty air filters

• Ensuring your system isn’t overworking or overheating

Don’t let extreme heat catch your generator off guard.

3. Ensure Your Generator is Ready for Summer Travel and Cottage Season

Many homeowners across Simcoe County and Muskoka rely on backup generators at their cottages or rural properties. If you’re heading north for the summer, the last thing you want to deal with is a generator that won’t start during a weekend away.

Before cottage season kicks into full swing, have your unit serviced to:

• Confirm remote-start or auto-start functions are working

• Check propane or fuel supply lines

• Avoid last-minute service calls while you're on vacation

Our team at Sparks Generators can also help with seasonal start-ups and service for portable units you bring to the lake.

4. Avoid the Summer Rush for Repairs

Once the summer heat sets in and outages begin, generator service calls spike across the region. Waiting until July or August to book your tune-up means:

• Longer wait times

• Limited technician availability

• Possible delays during emergencies

By scheduling your maintenance early, you:

• Beat the summer service rush

• Get priority attention and flexible scheduling

• Reduce the risk of costly emergency repairs

5. Protect Your Investment and Extend Generator Life

Your generator is a serious investment—one that plays a key role in protecting your home, appliances, and lifestyle. Like any mechanical system, regular maintenance helps extend its lifespan and ensures it runs efficiently year-round.

At Sparks Generators, a summer tune-up includes:

• Battery and electrical system check

• Oil and filter replacement (if needed)

• Inspection of transfer switch

• Load testing and performance assessment

• Fuel system inspection

• Cleaning and diagnostics

Proper maintenance not only keeps your warranty valid (especially for Generac models) but also ensures your generator stays ready to run for years to come.
