"It went very well. A diagnostic test was run and we discussed the results.

Alex telephoned me a couple times to discuss what he found and then explained what needed to be done. We discussed the overall cost and I told him to proceed.

Generator Install questions, answered by experts

Generator size requirements vary wildly among properties, but typical generator sizes are listed below based on home square footage:

  • 1,000 sq ft: 6–9 kW

  • 1,500 sq ft: 7–10 kW

  • 2,000 sq ft: 10–14kW

  • 2,500 sq ft: 12–16kW

  • 3,000 sq ft: 16–20kW+

Unfortunately, home square footage isn’t always a good indicator of generator size requirements. Instead, you should call in a professional to discuss which items in your home you’d like to run via your generator. They can calculate peak and average consumption for those items and then size your generator appropriately for optimal performance.

You can determine what size generator you need by listing the various appliances it will power during an outage. Write down the start-up watt usage, and then add them all together. 

A 7,500-watt generator will run your refrigerator, freezer, well pump, and lighting circuits without a problem. However, you’ll need an extra 3,000 to 4,500 watts to run your water heater and another 5,000 to 25,000 watts to run your electric furnace. In these instances, a whole-home generator is your best bet for running your critical equipment.

You can expect a diesel generator to last for up to 30,000 hours of use, which works out to 20 to 25 years with the proper maintenance, of course. That depends on how much you use it, so a diesel generator used for emergencies a couple of times a year will last a lot longer than a generator that takes over for a faulty electrical grid every month for a day or two. 

When properly maintained, natural gas generators can last a long time, as much as 20 to 40 years. They have relatively few needs compared to generators with other fuel types. However, the generator’s lifespan ultimately depends on how often the generator is used and for how long it’s left running.

Carbon monoxide emissions aren’t only dangerous to human life, but they also harm our planet. While natural gas generators emit lower levels of CO than other fuel sources, there are still ways to reduce emission levels. For example, shop around for an eco-friendly generator that complies with current emission standards. Also, make sure your generator is serviced regularly to avoid CO buildup.
