Honest HVAC. No Surprises.

Fair pricing, non-commissioned techs, and an owner who picks up the phone. Serving Union County & beyond.

Micah and his team were absolutely fantastic. They gave me a straight answer on what was wrong, told me exactly what it would cost, and didn't try to sell me anything extra. In an industry full of upsells, this was refreshingly honest. Will call them for everything going forward.

AC Repair
The installation was immaculate. Every line was perfectly placed, everything was labeled, and they cleaned up completely before leaving. You could tell these guys take genuine pride in their craft. The system has been running perfectly since.

AC Installation
I've used three different HVAC companies over the years. 3N1 is the first one where I felt like they were actually looking out for me rather than looking for ways to charge me more. I will never use anyone else.

Heating Repair
Fast turnaround, showed up on time, and the technician explained everything in plain language. They even helped me register the warranty afterward, which I never expected. Top-notch service from start to finish.

Heat Pump Installation
I had a quote from another company that seemed way too high. 3N1 came out, diagnosed the actual issue, and fixed it for less than half the original quote. These guys are completely trustworthy.

HVAC Maintenance
Called on a hot afternoon when our AC stopped working. Micah was professional, quick, and upfront about the cost before starting. No surprises on the invoice. Exactly the kind of service that's hard to find.

From the free estimate to the final walkthrough, the process was smooth and professional. Micah explained our options without any pressure, and the installation was clean and well-organized. Highly recommend.

Heating Installation
Honest, thorough, and reasonably priced. Didn't try to upsell me on anything I didn't need. Just a clean tune-up with a clear report on system condition. That's all I wanted — and that's exactly what I got.

AC Tune-Up
Installed a mini split in our garage addition. The work was clean, the installation was done in a few hours, and everything has worked perfectly. Micah was great to work with from estimate to completion.
