Standards That Never Change.

Serving Dayton Since 1950

Korrect Plumbing, Heating & Air Conditioning, Inc. has been a Dayton institution since 1950. Founded by N. Ivan Patterson and C. Edwin Hunn as a family business grounded in Christian values, we’ve grown into one of Ohio’s most trusted plumbing and HVAC installation companies, while never losing sight of what made us trusted in the first place. We’re a fourth-generation, family-owned business, and that history isn’t a marketing line. It’s the reason our standards don’t change based on the size of the job, the heat of the season, or what a competitor is willing to do.

Our team of licensed, NATE-certified technicians serves homeowners and businesses within approximately 20 to 25 miles of downtown Dayton, performing residential and commercial HVAC services, full-service plumbing, drain and sewer solutions, water treatment, and bathroom remodeling. We’re a Carrier Authorized Dealer and we bring that depth of product knowledge and technical training to every service call, from a $199 toilet repair to a quarter-million-dollar commercial project.

We do not use commission-based salespeople. We do not surge price after hours. We do not manufacture urgency or recommend work that is not warranted. Our technicians are focused entirely on solving your problem accurately, explaining your options honestly, and completing the work with the craftsmanship this company was built on.

When something breaks in your home, the last thing you need is a company you can’t trust. We’ve been the company Dayton trusts for 75 years, and we intend to keep it that way, one job at a time, one honest conversation at a time. The difference between Korrect and the companies that have entered this market in recent years isn’t a branding claim. It’s visible in how our technicians work, what they’re trained to do, how they price the job, and what they do when something isn’t right. We built this company on doing things the right way. We intend to keep it that way, as long as there are homes in Dayton that need honest service.

We built this company on doing things correctly, and we intend to keep it that way, one job and one honest conversation at a time.
