GPS is what their Facebook page calls ‘the 911 of Heating and Cooling.’ If your heat goes out at 2 a.m. or the AC fails on a holiday, the on-call line is staffed. Office hours are Monday-Friday 7:30 to 4:30, but the emergency line never closes.

Honest quotes. No hidden charges. Ever.
GPS Heating & Cooling has been operating out of 2600 Cleveland Avenue in Marinette for longer than most of the houses we service have been standing. The shop has been a Lennox dealer since 1952 — that’s over seventy years of installing, servicing, and modernizing one of the most reliable HVAC brands made. Today the team is led by owner Gerald J. Giese, with John Schramm as president and Steve Petraski as treasurer. Day to day, customers know us by Jerry on the sales side, Randy in the field, and Reid running installs. We hold both Wisconsin and Michigan licenses, so we cover Marinette, Menominee, and the surrounding Northeast Wisconsin region without the runaround. The thing customers say most often, in their own words: honest quotes, no hidden charges. We’ve worked hard to earn that.
