Harriman Heating & Air Conditioning

Harriman Heating & Air Conditioning has anchored itself in Farmington Hills, Michigan since 1996 as a family-owned, licensed heating and cooling contractor. With 1,599 verified five-star reviews and a 4.8-star average, the company has earned a reputation that extends well beyond its home base. The crew serves the greater Oakland County corridor, including Ypsilanti and Novi, handling everything from routine seasonal maintenance to full equipment replacements. Extended weekday hours running from 7:30 AM to 8 PM and a three-day weekend schedule make it practical for working homeowners to book appointments without disrupting their workday. The combination of longevity, high review volume, and accessible scheduling positions Harriman as a regional standard for residential comfort systems.

The Harriman team has built a practice around preserving aging residential infrastructure, a specialty that surfaces repeatedly in documented customer experiences. When a furnace fails during a cold-snap window, the crew installs a temporary rental unit so the household does not lose heat while a new high-efficiency Trane system is sourced and scheduled. This bridging strategy avoids the disruption of freezing pipes or water damage while a permanent replacement is coordinated. For homes still running cast-iron radiator systems, the company has demonstrated the ability to assess, repair, and source compatible components for heating setups that predate modern forced-air design. That hands-on familiarity with both legacy and current equipment gives the company uncommon range across the vintage housing stock that defines much of the region.
