Reviews From Our Clients

Nick came over to resolve an issue from a condensate pump installation and worked dilegently, crawling through a hot attic several times to fix an issue with the hose set-up. Korrect has handled multiple jobs in our home, including replacing a pump, an HVAC blower and a water heater all jobs well done, follow through if an issue, from the first phone call in with admin/the scheduler to the technician.

⭐️⭐️⭐️⭐️⭐️ **Excellent Service from Korrect Plumbing!** We had been dealing with a leaking Wolverine Brass shower faucet, and the cartridge needed to be replaced. I believe the water in our neighborhood is very hard, so I was concerned that the old cartridge would be very difficult to remove because of mineral buildup accumulated over the years. Korrect Plumbing sent Mr. Patrick and Mr Travis to our home this morning, arriving right on time between 8:00 and 9:00 a.m. They did an excellent job! Both Mr. Patrick and Mr. Travis were professional, knowledgeable, courteous, and very careful with the repair. They worked efficiently and did a wonderful job replacing the cartridge. It was clear that they knew exactly what they were doing. We are very happy with the work and so relieved to finally have our leaking shower faucet repaired. We truly appreciate their time, effort, and expertise. A special Thank You to Ms. Kerri for arranging everything and for sending such wonderful technicians to our home. She was so helpful throughout the process, and I really appreciate her excellent customer service. And of course, a big Thank You to Mr. Patrick and Mr. Travis for doing such a great job! We are very pleased with the repair and truly appreciate everyone's help. Korrect Plumbing is lucky to have such great people on their team. I would definitely recommend Korrect Plumbing to anyone looking for professional, reliable, and friendly plumbing service. **Five stars all the way! ⭐️⭐️⭐️⭐️⭐️😊**

First time dealing with Korrect and was very pleased. I called asking for a water heater installation estimate and received it over the phone. Two days later the tank installed without any issues. It was refreshing to deal with a company that doesn’t try to upsell and push extended warranties. I will definitely call upon Korrect for future plumbing projects.

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.
