Pro Serv Plumbing, Heating, and Cooling

Pro Serv Plumbing, Heating, and Cooling operates as a family-owned contractor in Wauwatosa, Wisconsin, delivering plumbing, heating, and cooling solutions to residential and commercial clients across the Milwaukee metropolitan area, including Wauwatosa and surrounding communities. The business is led by Jon Weis, a Master Plumber and HVAC Contractor whose technical training originated in the U.S. Air Force, where he learned to maintain plumbing, heating, and cooling systems under military standards. Pro Serv maintains round-the-clock availability seven days a week and holds accreditation from the Better Business Bureau and the Milwaukee Builders Association. The company has earned 257 five-star reviews, reflecting consistent customer satisfaction throughout its years of operation in the local market.

What distinguishes Pro Serv from other contractors in the Milwaukee area is the hands-on leadership of an owner who brings military-quality training to every service call. Jon Weis personally oversees projects and trains technicians to the same rigorous standards he learned in the Air Force. The company offers comprehensive services spanning all three trades under one roof, eliminating the need for homeowners to coordinate multiple contractors when plumbing and HVAC issues overlap. Their 24/7 emergency availability ensures that customers facing heating failures during cold snaps or cooling breakdowns during summer heat waves can reach a qualified technician any time, day or night.

Customer reviews highlight specific technicians who have resolved unusual or urgent problems. Justin addressed a boiler recall issue by sourcing a discontinued part before the manufacturer went out of business, keeping the customer's furnace running reliably. Tom arrived on Christmas Eve with the correct replacement part, solving a heating emergency during the holiday weekend. Andy repaired a gas leak in a newly purchased home while also replacing a non-functional sump pump, taking time to explain the older system's history to the homeowner. These scenarios demonstrate the company's ability to handle complex repairs that require parts knowledge, rapid response, and technical adaptability.
