Excellence has been our hallmark since 1947.

Holt Plumbing & Heating was founded by John F. Holt and his wife Edith in 1947. John was a skilled sheet metal worker and welder who honed his skills building B-26 and B-29 airplanes at the Martin Bomber Plant in Omaha, Nebraska during World War II. Edith, who also taught elementary school for many years, served as secretary and bookkeeper for the business.

After the war, they came back to the family farm south of Afton, Iowa. John continued to put his metalworking skills to use, repairing machinery for neighboring farmers. This led to plumbing work and eventually heating, cooling, and even appliance sales.

In 1959, John and Edith officially opened John F. Holt Plumbing & Heating in Afton. In the mid-1970s, their son Lynn, who had been working in the plumbing industry in Des Moines, came back to join them in the family business. In 1977, Lynn and his wife Dixie opened a second location in Winterset that quickly grew to service Des Moines and its surrounding areas. And in 2012, they moved their headquarters to 245 Railroad in Valley Junction. Holt’s business is truly a family affair. Lynn and Dixie’s two children, Ben and Amanda, and Amanda’s husband Josh all work in the business as well.

"Looking for a no fluff, no BS review of Holt? I got you... Over the past 15 years I've been a home owner, We've tried more companies that I could count. Lots of shady businesses out there... We were coming of a brand new HVAC installation just two years ago and the previous company completely botched it. It had problems within a month of installation and they were completely MIA. We ran it as long as we could to try and recoup the some cost, but it was a constant worry. Decided to give Holt a chance and we're so glad we did! Yes, they were more expensive, but it's the classic "you get what you pay for". 100% worth it! It's so hard to find a company that has the perfect mix of quality, punctuality, and honesty and Holt nails it. I genuinely appreciate their level of service and will pay a bit more to have someone I have the utmost confidence in doing the right thing. You should definitely give them a look if you need heating, cooling, or plumbing work."

"I highly recommend Holt! I needed my water heater replaced, and they came out and took the time to discuss all of my options and to make sure that I fully understood everything about the project. They did quality work, with all of the plumbing in traditional copper. That was important to me because I didn't want any of that PEX in my home! My entire basement looks cleaner and tidier because of the work they did! I was also very impressed that they didn't talk down to me as a woman. I like to do my own appliance maintenance and repairs when possible, and they respected my desire to understand everything about the installation and the prospective maintenance into the future."


"We had never heard of Holt Heating and Plumbing until today. We had an emergency and needed service immediately and Holt was available. Israel was our technician and he was amazing! They will have our business for years to come! Thanks Israel and Holt!"


"Holt heating and air conditioning installed our heating and air conditioning system and now we have the maintenance program with them. All the different people we'd have had out to do the semi annual maintenance have been courteous and professional in there attire and speaking to us. I would use them for other services in a heartbeat."


"The best experience you could ever ask for. Nick is very skilled and knowledgeable about his industry. We were in a challenging situation and Holt and Nick were there to help us. Nick is very professional, extremely polite and friendly and very skilled. Thank you all so very much"
