Summer Systems

Doing Things ‘the Right Way’

Since 1987, Don London originally started Summer Systems as a HVAC and electrical business that focused on serving banks. London developed an immediate reputation for his attention to detail and consistency with which he delivered high-quality services. He believed in doing things “the right way”.

To this day, Summer Systems enjoys the same reputation. Our company remains committed to delivering top-notch services with market-oriented efficiency. We have used this approach to service our clients in the high-demand world of retail banking for over 20 years.
