About Wohlers Heating & AC
Wohlers Heating & AC has been keeping homes comfortable in Cottage Grove and Madison since 1991, building three decades of steady reputation in Dane County. The company holds a 4.5-star average across 35 verified reviews, reflecting consistent service over time. Their technicians are available Monday through Friday from 7AM to 5:30PM, with Friday hours ending at 3PM, serving residential and commercial throughout the greater Madison area.
What distinguishes Wohlers is their willingness to tackle non-standard installations. Reviewers note the team researched options for a two-stage system despite challenging installation constraints, working until the setup met the customer's exact specifications. They handle equipment from major manufacturers including Rheem, Mitsubishi, and Weil-McLain, with expertise in ductless mini-splits, heat pumps, and geothermal systems. Their Indoor Air Quality services cover whole-house humidifiers, high-efficiency filtration, and air purification, useful in Wisconsin's variable climate.
The customer stories from reviews reveal technicians who show up when it matters most. During a sweltering July day with an infant in the home, Chuck arrived the same day to diagnose a failed AC unit and replaced the component to restore cooling immediately. Another reviewer describes Dave spending time on a cramped basement project, explaining options rather than simply issuing a quote. These specific scenarios, named technicians handling real problems, drive the recurring theme across reviews: responsive, knowledgeable service from a team that's been at this for decades.
What Customers Say
Seven of seven sampled reviewers award 5 stars, with two specifically naming technicians (Chuck, Dave) who provided same-day emergency response or detailed system design. The four-star reviews cite product support and warranty backing rather than service quality issues, indicating consistent workmanship across jobs.
