Whole-Home Generator Cost Breakdown
At NW Generator Pros, we strive for transparency with all of our projects. One of the most common questions we know people have is how much a whole-home standby generator costs - we get it! Here's the thing: every home is different which means every installation is different and so are costs. The low end of the range on average is about $10,000 for a smaller generator and minimal amount of installation work needed. The average of the higher of the range is about $25,000. Again, please understand that this is an average range and there's room for exceptions. Our goal is to make installing a whole-home generator attainable for anyone. With our financing options, most projects start as low as $400 a month. Learn more about financing options and a 0% APR promo offer for those that qualify.
