The 5-Star review is for Tony, the technician who fixed the problem with our furnace. Our furnace was installed in 2018 but had never worked properly. Tony spent the time to diagnose the issue and we finally have a furnace that works as it should.
Our furnace was not giving out enough heat and we called Miller's to send a service technician. Sonny came out the next day, quickly diagnosed the problem, made a few other checks, and fixed it. He was friendly, knowledgable, and completed the work is less than an hour. We will call Miller's again the next time we have an issue.
We had a faulty furnace with a bad inducer motor, and after a truly disappointing experience with another HVAC company (rhymes with Spaz), I found Millers — and what a difference.From the first call, Kelly made scheduling easy and pleasant. Dominic (hope I’m spelling that right) showed up right on time, quickly diagnosed the issue, confirmed the part was in stock, drove to their warehouse to pick it up, and had our furnace fully repaired the same day.The service was fast, professional, and priced very reasonably. I’m seriously impressed — I’ll be calling Millers again for any future HVAC needs and recommending them to everyone I know.
I’ve used Miller’s HVAC several times now, and they’ve become my go-to local HVAC company for anything related to AC repair and heating/cooling service. The first two times, Sonny came out. He’s incredibly knowledgeable and helped diagnose and fix our AC issues in our older home. He added freon, replaced a few parts, and got our system running much more efficiently.A few months later, we hired Miller’s HVAC again for a full ductwork replacement under our house. Their three service techs were fantastic. On day one they took measurements and removed all the old ducting, and on day two they returned to install everything. They worked fast, cleaned up thoroughly, and even caught a blown fuse on our AC unit and repaired it on the spot.The owners, DJ and Kelly, are wonderful, the communication is great, and you can tell this is a small local business that truly cares about quality and customer service. If you need AC repair, ductwork installation, or HVAC maintenance in the area, I highly recommend Miller’s HVAC. They’ve taken great care of us every time!
I’m thrilled to share my experience with Millers Air Conditioning after my recent installation of a new air conditioning unit. They were so quick to come out and give me a quote, and I was impressed that they were able to start the job right away! The team was prompt, professional, and incredibly knowledgeable, making the entire process seamless. I appreciated their attention to detail and dedication to ensuring everything was perfect before they left. It’s refreshing to work with a locally owned family business that truly cares about its customers. If you’re looking for quality service and a dependable product, I highly recommend Millers Air Conditioning!! They’ve definitely earned my trust!
