Sullivan Furnace, AC Repair & Plumbing

Sullivan Furnace, AC Repair & Plumbing has earned a 4.9-star rating from 208 reviews in Kentwood, Michigan. The contractor operates around the clock every day of the week, providing air conditioning repair, furnace service, and plumbing to homeowners across the greater Grand Rapids area including Kentwood, Wyoming, and Grandville. Customers describe technicians who arrive prepared to explain diagnostic findings in plain language rather than industry jargon.

Reviewers repeatedly highlight the contractors willingness to coordinate additional trades when a single job reveals broader home issues. One customer noted Sullivan arranged electricians for a failing electrical panel during a furnace replacement, saving the homeowner from making separate calls. The team maintains professional demeanor throughout projects, from the initial sales discussion through installation and final system walkthrough.

Matt drew particular praise for arriving on the coldest weekend of the year to diagnose a heating failure, taking time to explain each diagnostic step to a homeowner facing an expensive replacement decision on a 19-year-old system. Chris Fisher completed a full furnace installation during a polar vortex, getting a family warm the same night. For Marcia, whose furnace failed during the coldest week on record, Sullivan provided options and returned the next morning to install a complete new system before competitors could schedule follow-up appointments.
