"New Era HVAC was amazing! I own a small business that has a very challenging environment to work around. Jared was extremely professional and minimized the disruption to our routine. We have large warehouse heaters. A few years ago we had one installed by another company. They left a huge mess, took 2 1/2 days to do the work and had no regard for disrupting our business. In contrast, when Jared replaced the second one he was done in one day, left the area clean and neat when he left, and was extremely accommodating with us. We have also had a tankless water heater replaced by New Era and had the same experience. Professional, honest, and reliable - you will not find a better company out there!!"

"I had a great experience from start to finish with this company. They were able to install my new AC unit quickly, which I was thankful for, considering how hot it has been. Throughout the entire process, they were transparent with their pricing, explained everything clearly, and never made me feel pressured. Dylan and Tristan were incredibly knowledgeable, professional, respectful, and kind. They took the time to answer all of my questions and made sure I understood what was being installed and why. I was honestly pretty stressed about having to replace my AC unit, but they made the entire experience easy and worry-free. I would absolutely recommend this company to anyone looking for honest, reliable HVAC service. Their customer service and quality of work exceeded my expectations, and I couldn't be happier with the experience."
