William Cannon Heating & Air serves Collierville and surrounding Tennessee communities with heating and cooling solutions, earning a 4.4-star rating across 30 customer reviews. The business operates Monday through Friday from 8 AM to 4:30 PM, providing scheduled service appointments for residential heating and air conditioning needs.

Reviewers frequently praise the company's diagnostic skill and willingness to explain issues thoroughly. One customer described how a technician correctly identified a faulty thermostat as the root cause rather than recommending an expensive zone board replacement that another contractor had suggested.
