Sacramento Drill Tower

With VRF, we don’t see our customers as much. I visit them every so often. They say, ‘We don’t have to call you anymore. Everything is working fine.’

The Sacramento Drill Tower, Sacramento, California, is two-thirds water tank, one-third offices for the city. When the offices’ old HVAC system failed, a new VRF system from Mitsubishi Electric came to the rescue. The result? Easy maintenance, a 50 percent reduction in energy usage and a total cost savings of 19 percent. For the City of Sacramento, that means $5,000 saved every single year.
