About

Monon Mechanical was founded by my dad in 2005. I'm Trent, second-generation owner, and we still answer the phones ourselves. About 70% of our work comes from neighbors recommending us, and that's how we like it. I personally walk every job before we start so the homeowner knows exactly what to expect. If you've ever felt rushed or upsold by a contractor, you'll notice the difference right away. Demo listing

Could not ask for better. Trent and they added a smart thermostat and walked my dad through how to use it.

Truly above and beyond. Trent and they installed a new variable-speed AC and the upstairs is finally comfortable.

Very happy with the job. Trent and they redid our return air ducts and the difference in airflow is night and day, and they offered three different options at three different price points. Glad we picked them.

Great experience with one tiny nitpick. Trent and they tuned up our system in October and it ran flawlessly all winter, and they called the night before to confirm. Would call them again without hesitation.

Would recommend to friends. Trent installed a new variable-speed AC and the upstairs is finally comfortable, and the whole crew showed up exactly when they said they would. They also stuck to the original quote with no surprise add-ons, which we really appreciated. Highly recommend with one minor caveat — but no big deal.

Absolutely the best experience we've had with a contractor. Trent and they replaced our 20-year-old furnace right before a deep freeze.

Wish we had gone with someone else. Trent and the crew redid our return air ducts and the difference in airflow is night and day, and they called the night before to confirm. Hard pass.

We're customers for life now. Trent and they added a smart thermostat and walked my dad through how to use it, and they had a clearly labeled truck and uniformed crew. Will be using them for everything from now on.

Job is finished and works fine, just not blown away. Trent and the team diagnosed a ductwork airflow issue that previous companies just sold us on a new unit for, and they sent us photos of the progress while we were at work. Fine for a basic job, not sure for anything complex.

Genuinely good work and good people. Trent replaced a cracked heat exchanger and explained exactly why it failed, and the whole crew took the time to answer every question we had. They also left the worksite cleaner than they found it, which we really appreciated. Would call them again without hesitation.

Decent work, mixed feelings. Trent and the team installed a new variable-speed AC and the upstairs is finally comfortable, and they picked up after themselves every single day. We'd probably try them again, but get a couple other quotes first.

Hands down the easiest home-service decision we've made. Trent redid our return air ducts and the difference in airflow is night and day, and the whole crew called the night before to confirm. They also sent us photos of the progress while we were at work, which we really appreciated. We've already recommended Trent to two neighbors.

Job is finished and works fine, just not blown away. Trent and the team set up a whole-home humidifier and we finally don't get nosebleeds in winter.
