Guardian Heating and Cooling

Guardian Heating and Cooling LLC operates as a family-owned HVAC contractor serving West Allis and the greater Milwaukee metropolitan area from two established locations in Mequon and Oak Creek. Founded in 2019, the company holds Wisconsin state licensing and provides heating and cooling services across Ozaukee, Milwaukee, Washington, and Waukesha counties. The business maintains a 4.2-star rating compiled from ten customer reviews, with eight reviewers awarding full five-star feedback. Operating around the clock every day of the week, Guardian Heating and Cooling responds to emergency service calls for both residential households and light commercial properties throughout the Milwaukee metro region.

What distinguishes this contractor among regional competitors is their commitment to transparent pricing and comprehensive service offerings. The company guarantees all workmanship and maintains invoice practices that reviewers consistently describe as honest and un padded. Their service menu spans beyond standard HVAC work to include snowmelt system installations for residential driveways and walkways, in-floor heating using gypcrete methods, geothermal system installation, and professional-grade mini-split systems. They also handle water heater installation and boiler repair and servicing, positioning them as a single source for complete home comfort solutions rather than a narrow specialty shop.

Customer testimonials reveal two named technicians who form the operational core: Steve and Adam, described by repeat clients as a father-son duo who handle service calls personally. Reviewer Gerald Grzeca detailed how this team tackled an extraordinarily difficult removal of a jammed air handler from a two-foot crawl space that two other contractors refused to bid on, disassembling the unit piece by piece to avoid ceiling demolition. Another reviewer, Lynn E., noted Steve arrived a day early to address an urgent need for a household with a disabled child. Steve also returned the following day to verify continued operation. Client Vadim Arutyunyan noted a furnace and AC installation followed by a no-charge service call when the AC developed issues. These scenarios illustrate the team's willingness to stand behind their installations well after completion.
