The Generator Buyer's Checklist: What to Ask Before Making a Purchase

A 2022 report by Electrek showed only 15% of American homes had backup power sources like standby generators, yet demand for reliable backup power keeps growing. Blackouts happen unannounced, causing food spoilage, stopping security systems, and making homes vulnerable. A reliable generator is more than a convenience; it is a necessity. Before buying, here is what to ask.

Why do I need it?

Determine the generator's purpose, which drives size and budget. First decide what it will power, then calculate the wattage of appliances such as washing machines and dryers, refrigerators, cookers, electronics, lighting, water heaters, and security systems. Also consider how often you will use it, whether for long-term supply or short outages.

How much does it cost?

Understand the total cost, from the unit itself to transportation and installation. Compare prices from several sellers and ask for a long-term cost estimate covering fuel, maintenance and servicing, installation, and insurance. If budget is tight, consider a refurbished unit, but test it first; buying off-season in spring and early summer can also save money, and do not forget to ask about discounts and rebates.

What fuel does it use?

Fuel type drives efficiency and runtime. Diesel is efficient and long-lasting but pricey and higher-emission; gasoline is affordable for smaller portables but less efficient with a shorter shelf life; propane burns cleaner and quieter but lowers runtime due to lower density; natural gas needs no storage but is not for portables. Weigh safety and storage, cost, sustainability, availability, and environmental impact.

How loud is it?

A loud generator makes your home uncomfortable and can draw fines or neighbor complaints. Get it tested at idle and full power, read decibel ratings, and research owners' reviews to understand real noise levels.

What size of generator do I need?

Power output determines size. An overly large unit wastes energy and money, while the right size prevents overloads and protects sensitive devices. Other size factors include usage requirements, fuel type, starting vs running watts, and portability. Sizes range from small portables to medium home/business units to large residential/commercial models to extra-large units for factories and hospitals.

Does it have a warranty?

A warranty covers repair costs and often includes quality maintenance. Ask about parts and labor, manufacturer's, installation, and extended warranties.

What safety features does it have?

Functional safety features prevent fire hazards, carbon monoxide poisoning, electrical shocks, and appliance damage. Look for a carbon monoxide sensor, automatic low-oil shutoff, circuit breaker protection, remote start and auto-transfer switch, spark arrestor, and GFCI outlets.
