Williams Brothers AC and Heat

Williams Brothers AC and Heat has served Ann Arbor homeowners since 2005, operating from 1100 Victors Way in the 48108 zip code. The family-owned business, founded by Duane Kemp, holds a 4.9-star rating across 16 verified customer reviews. Their NATE-certified technicians provide heating and cooling services throughout Ann Arbor and surrounding Washtenaw County, with 24-hour emergency availability seven days a week.

What distinguishes Williams Brothers from other area contractors is their commitment to transparent diagnostics and comprehensive workmanship guarantees. The company offers a 10-year warranty on both labor and parts for new furnace installations, a coverage period significantly longer than industry standard. Their service catalog spans residential and light commercial projects, including complex multi-zone ductwork systems and hybrid heat pump/gas furnace configurations. Same-day service is standard for routine calls, while their around-the-clock emergency line ensures homeowners never face a heating or cooling crisis without rapid response.

Reviewers consistently highlight specific team members who delivered exceptional service. Diana Browning praised technicians Jonah and Bradley for navigating a challenging multi-zone furnace installation, noting that the owner personally intervened to verify ductwork connections. Maddox Coffey described a heat pump replacement where the team declined to sell equipment until confirming the old 20-year-old unit genuinely required replacement, demonstrating the honest, thorough approach that earns repeated customer loyalty.
