"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."

"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."

"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."
