About J & B Heating & Air Conditioning
J & B Heating & Air Conditioning serves Greendale, Wisconsin as a local HVAC contractor with a 3.6-star rating drawn from 29 customer reviews. The company operates Monday through Friday from 8 AM to 4:30 PM, providing residential heating and cooling services to homeowners throughout the Greendale area. While the company has collected meaningful feedback from nearly three dozen clients, prospective customers should weigh both the positive and critical assessments when evaluating whether to request service.
The company handles emergency repairs and standard maintenance appointments for heating and cooling systems. Based on review accounts, J & B provides same-day service for urgent situations and offers initial estimates over the phone before dispatching a technician. One reviewer noted the company honored the quoted trip fee and labor cost without additional charges, though other reviews raise concerns about warranty fulfillment and post-installation follow-up.
Customer experiences highlight contrasting service outcomes. One reviewer described working with Jon, who arrived same-day during a heating emergency and provided clear communication throughout the repair process, with the quoted price honored. However, another reviewer reported a furnace developing a leak within six months of installation, and a third account described frustration when the company did not honor warranty claims and communicated via text rather than phone calls. These conflicting experiences suggest homeowners should request written warranty documentation and confirm service terms before agreeing to major repairs.
What Customers Say
Three reviews cite contrasting service quality: positive reviews praise same-day arrival and transparent pricing, while negative reviews cite furnace failure within months and warranty disputes. Matthew Fett named technician Jon and awarded 5 stars; two other reviewers awarded 1 star each citing product and warranty issues.
