Purchasing a home generator is a smart investment, especially for Long Island homeowners who face unpredictable storms, grid overloads, and harsh seasonal weather. But making the wrong decision can cost you time, money, and peace of mind. If you’re thinking about buying a generator on Long Island, be sure to avoid these seven common mistakes that homeowners often make.
1. Choosing the Wrong Generator Size
One of the biggest mistakes homeowners make is selecting a generator that’s too small—or unnecessarily large—for their needs. A unit that’s too small won’t power all your essentials, while an oversized generator can lead to wasted fuel and higher installation costs. A professional load analysis is essential to ensure your generator matches your actual energy requirements. Commander Power Systems helps you determine the right size based on your home’s systems, from HVAC and lighting to appliances and security features.
2. Failing to Plan for Fuel Source and Availability
Not all generators run on the same type of fuel. Some use natural gas, others propane, and some diesel. One of the most common home generator mistakes is not considering what fuel is readily available or practical for your property. For example, if your home doesn’t have a natural gas line, a propane tank may be a better choice. Understanding fuel logistics ahead of time helps avoid operational issues later on.
3. Skipping the Site Assessment
Many homeowners make the mistake of purchasing a generator before consulting a professional. Without a proper site evaluation, you risk poor placement, inefficient wiring, or exposure to flooding and ventilation issues. A thorough on-site assessment identifies the safest and most effective location for your unit and lays the foundation for a reliable installation.
4. Forgetting the Automatic Transfer Switch (ATS)
A generator is only part of the equation. You also need an automatic transfer switch that detects power loss and turns on the generator instantly. Skipping the ATS means you’ll need to start the generator manually—an inconvenience during dangerous storms or nighttime outages. Every Commander Power Systems installation includes ATS integration to ensure seamless performance when the power goes out.
5. Overlooking Maintenance and Service Plans
A generator isn’t a one-time purchase—it’s a system that needs regular maintenance to remain dependable. One of the most overlooked parts of any generator buying guide is post-installation care. Oil changes, filter replacements, and load testing are crucial to ensure your unit is always ready. Commander Power Systems offers preventive maintenance plans that keep your generator in peak condition year-round.
6. Choosing Price Over Quality
It’s tempting to go with the cheapest option, but not all generators—or installers—are created equal. Buying a low-cost unit or hiring an unlicensed contractor can lead to performance issues, safety hazards, or costly repairs down the road. Trust an experienced, certified team like Commander Power Systems to install high-quality equipment backed by expert support and long-term service.
