About Williams Brothers AC and Heat
Williams Brothers AC and Heat has served Ann Arbor since November 2017, earning a 4.9-star average across 16 verified customer reviews. The family-owned company, founded by Daniel Coleman, dispatches NATE Certified technicians throughout Ann Arbor and the broader Washtenaw County region. The firm carries full licensing, bonding, and insurance coverage for residential and light commercial HVAC work, building its reputation one completed job at a time.
What sets Williams Brothers apart is pairing NATE factory certification with round-the-clock emergency availability six days a week. They offer same-day service windows and detailed quotes that give homeowners options to supply their own AC unit or have the company provide one. New system installations include complementary thermostat setup, and they will pick up customer-purchased equipment for a modest handling fee. This flexibility lets budget-conscious homeowners make informed purchasing decisions without compromising installation quality.
Misty Rodgers needed a full AC replacement and worked directly with Craig, who walked her through itemized pricing with and without unit costs included. Craig answered her questions even on a weekend, and the crew completed the installation and new thermostat setup before Michigan summer heat arrived. Another reviewer, Christine Santos, received a high-efficiency furnace when competing companies said the lead time would stretch for weeks. Jeffery expedited her order, and the installation crew treated her Ann Arbor home with care, cleaned up completely, and walked her through the new thermostat. During a scorching summer day, Ruben arrived same-day to restore a failed cooling system, a responsiveness pattern that has kept this reviewer loyal for multiple years.
What Customers Say
All three detailed reviews award 5 stars and each names a specific technician. Misty credits Craig for flexible pricing and weekend availability during an AC replacement. Christine highlights Jeffery for sourcing a high-efficiency furnace faster than competitors promised. Carlos mentions Ruben for same-day emergency service during a heat wave. The consistent thread across reviewers is rapid response, professional communication, and transparent pricing.
