Williams Heating & Cooling

Williams Heating & Cooling operates as an air conditioning contractor serving Sullivan, Missouri and surrounding communities. With a rating of 4.4 stars drawn from 47 customer reviews, the company maintains standard weekday hours from 7:30 AM to 4:00 PM, closing on weekends. Reviewers in the area have described interactions with team members including Matt and Bridon, noting their approach to both installation projects and repair diagnostics.

The company handles mini-split system installations, with one reviewer highlighting the WiFi connectivity feature that allows remote monitoring and control through a mobile application. This type of system represents a growing segment in the residential market for homes without traditional ductwork.

Several reviewers share specific service experiences. Carol Hemker described a team that arrived punctually for a mini-split installation, calling the price and quality hard to match elsewhere in the area. Diane Jablonski noted that Bridon arrived shortly after 9:00 AM for a same-day appointment and resolved the issue quickly, describing the technician as clean, courteous, and knowledgeable. In contrast, Mike K. reported a diagnosis that led to a $1,000 part recommendation which did not resolve the issue, and Raymond Roberts described multiple visits that failed to restore heat during cold weather.
