The Commercial Heating and Cooling Experts in the Greater Lake Country Area

We’ve provided HVAC service to some of the community’s most recognizable, high-profile businesses and commercial facilities, including Rogers Memorial Hospital, and St. Jerome Church. These successful, well-coordinated projects all resulted from the relationship we had upfront with the design team. We understand the tough demands of construction projects. And we play an active role during both the preconstruction and construction phases—while keeping specifications, and your needs and budget in mind.

Our skilled technicians are dedicated to serving all your HVAC needs. They have a combined 140 plus years of experience doing a variety of commercial work. We pride ourselves on superior customer service. Let us add you to our growing list of satisfied commercial customers by calling to arrange an on-site estimate today.


Commercial Projects We’ve Worked On:

First Bank Financing Center – Oconomowoc

First Bank Financial Center is a full-service, independent community bank that has served Southeastern Wisconsin for more than 150 years. Since being founded in 1859, the bank has expanded to include 12 full service locations. Pat’s Heating has partnered with First Bank as they’ve grown over the years providing new construction, remodeling, and maintenance services to all of its branch locations. The bank is committed to community banking values and focuses its attention on the needs of local families and small businesses while providing exceptional service and sound financial advice.
