About

Hi, I'm Greg and I started Hamilton County HVAC 26 years ago after my own family had a bad experience with a national chain. I grew up in Hamilton County and went through Carmel schools, so this town isn't just my market — it's home. About 70% of our work comes from neighbors recommending us, and that's how we like it. Quotes are free and there's never any pressure. Demo listing

Truly above and beyond. Greg and they set up a whole-home humidifier and we finally don't get nosebleeds in winter.

Wow — what a refreshing experience. Greg installed a Mitsubishi mini-split in our bonus room above the garage, and the whole crew made sure our dog was comfortable around the crew. They also took the time to answer every question we had, which we really appreciated. We've already recommended Greg to two neighbors.

Wow — what a refreshing experience. Greg installed a new variable-speed AC and the upstairs is finally comfortable, and the whole crew sent us photos of the progress while we were at work. They also had a clearly labeled truck and uniformed crew, which we really appreciated. If you're on the fence, just call them.

Job is finished and works fine, just not blown away. Greg and the team replaced a cracked heat exchanger and explained exactly why it failed, and they offered three different options at three different price points. Fine for a basic job, not sure for anything complex.

Mostly a positive experience with some hiccups. Greg and the team redid our return air ducts and the difference in airflow is night and day.

Solid work overall, would use again. Greg installed a new variable-speed AC and the upstairs is finally comfortable, and the whole crew offered three different options at three different price points. They also wore booties in the house without being asked, which we really appreciated. Glad we picked them.

Job is finished and works fine, just not blown away. Greg and the team added a smart thermostat and walked my dad through how to use it, and they showed up exactly when they said they would. We'd probably try them again, but get a couple other quotes first.

Absolutely the best experience we've had with a contractor. Greg and they installed a Mitsubishi mini-split in our bonus room above the garage, and they showed up exactly when they said they would. Ten out of ten — this is how it should be.

Mostly a positive experience with some hiccups. Greg replaced our 20-year-old furnace right before a deep freeze, and the whole crew had a clearly labeled truck and uniformed crew. They also showed up exactly when they said they would, which we really appreciated. We'd probably try them again, but get a couple other quotes first.
