J & B Heating & Air Conditioning holds a 3.6-star rating compiled from 29 customer reviews, positioning the contractor in the moderate range for local HVAC service providers. Based at 6170 Industrial Ct. in Greendale, Wisconsin, the company has operated continuously since 1968, making it a established fixture in the greater Milwaukee, Waukesha, and Racine County markets. The contractor maintains standard weekday hours from 8 a.m. to 4:30 p.m., Monday through Friday, with emergency callback service available around the clock for urgent situations.
The company distinguishes itself through comprehensive service breadth, handling repairs across all major gas furnace and boiler brands, central air conditioning systems, and offering specialty services such as condenser and evaporator coil cleanings to optimize system efficiency. Residential duct cleaning and whole-home humidifier installation represent notable add-on capabilities that extend beyond standard repair and maintenance offerings. The contractor provides financing options for approved credit applicants and currently promotes a $20 discount on service calls, creating accessible entry points for homeowners evaluating new system installations or significant repairs.
Customer experiences documented in reviews reveal mixed outcomes. Matthew Fett described a positive encounter with technician Jon, who provided same-day service after a heat system failure, delivered the initial estimate over the phone, arrived on time, and completed the repair at the quoted price without upselling unnecessary services. Conversely, John Conlin reported an emergency service call where the technician claimed unfamiliarity with the furnace brand that J & B had sold and installed in 2019, forcing the homeowner to seek assistance from a different company. Another reviewer documented a furnace leak appearing six months post-installation, claiming the company declined to honor its one-year warranty and required hourly payment for service calls.
What Customers Say
Mixed sentiment dominates the 29-review sample: positive feedback emphasizes same-day responsiveness and transparent pricing, while negative reviews focus on product knowledge gaps and warranty fulfillment disputes.
