Claim This BusinessAll-Knight, Inc. has served the Columbus community since its founding, delivering heating and cooling solutions to homeowners throughout Franklin County and surrounding neighborhoods. The company holds proper state licensing for HVAC installation and repair, and maintains a 4.6-star rating aggregated from 63 client reviews, a track record that speaks to consistent service quality. Whether you reside in Clintonville, Westerville, Dublin, or Grandview Heights, All-Knight dispatches certified technicians to diagnose and resolve equipment issues across the full spectrum of residential heating and cooling systems.
Jim and Dustin comprise the core service team, and customer feedback consistently highlights their approach as low-pressure and transparent. Reviewers note that technicians arrive when promised, explain repair options without upselling, and occasionally inform homeowners when replacement isn't yet necessary, a practice that builds long-term trust rather than maximizing short-term invoice amounts. The company maintains 24-hour availability on weekends, a rare commitment in the Columbus market that proves valuable when system failures occur outside standard business hours.
Specific scenarios from recent reviews illustrate the team's responsiveness: a same-day Saturday call resulted in repair arrival within one hour for a family with a newborn, another technician identified an active warranty saving the homeowner thousands on a prospective furnace replacement, and a past visit resolved an issue two previous contractors had misdiagnosed. Technicians bring equipment and parts directly to appointments, enabling on-site resolution rather than multiple trips.
Five of six detailed reviews specifically mention same-day or Saturday emergency response, with Andrea S. receiving service within one hour of her Saturday morning call. Three reviews cite instances where the company advised repair over replacement, saving the homeowner unnecessary expense, a notable pattern distinguishing All-Knight from contractors who prioritize equipment sales.
