We Recommend Based on Reliability

Dunn Electrical Service chooses to work with only two generator manufacturers for a reason. When it matters most you can rely on Briggs & Stratton brand generators to deliver power when your service area experiences a power outage. You can shop based on price however, we recommend based on experience.

Dunn Electrical Service stands behind these recommendations based on hands-on experience being on-site with customers when an (alternate brand) generator fails to deliver power in an emergency. Your safety and the convenience of having continuous power is a matter of reliability and confidence rather than which generator is the lowest price. Lower priced products can often set you up to fail when it matters most. Call or contact us to today to discuss your needs, so we can make a solid recommendation to meet or exceed your emergency power needs.
