Claim This BusinessMajor Mechanical operates as a HVAC contractor in New Berlin, Wisconsin, delivering heating and cooling solutions to residential and commercial clients across the greater Milwaukee metropolitan area, including nearby Waukesha. The company holds a perfect 5.0-star rating compiled from 58 client reviews, reflecting consistent customer satisfaction in a region where summer humidity and winter temperatures demands reliable year-round system performance.
What distinguishes Major Mechanical is their capacity to pivot between large-scale commercial compressor installations and urgent residential repairs. One reviewer documented a 50-HP industrial compressor replacement completed within a single week, while another client described a same-day furnace restoration following a quick phone call. The company's response flexibility suggests they maintain both the technical expertise and workforce availability to handle projects typically reserved for larger firms.
Customer reviews name specific technicians who handled distinct scenarios. Ron, described as kind and accommodating, assisted a client during the Thanksgiving holiday weekend by connecting them with a specialist who completed boiler repairs that same evening. Jack K performed routine maintenance on a downtown high-rise condenser unit, with one client noting he spent more time on-site checking systems than previous contractors who charged significantly higher rates. These named interactions demonstrate the company's ability to deliver personalized service across different property types.
All 58 reviews carry 5-star ratings, with at least three clients specifically naming technicians Ron, Jack K, or Walter Dosedla who resolved their issues. Holiday weekend emergency response and same-day furnace repair appear in separate reviews, suggesting the company accommodates urgent requests despite standard weekday operating hours.
