Owned and operated by Doug Reinhardt
Hello — I'm Doug, founder of Patel Comfort Systems. We've been quietly building a reputation around Hamilton County for 12 years. About 70% of our work comes from neighbors recommending us, and that's how we like it. We don't subcontract anything out — every person on your property wears our shirt and is on our payroll. I'd be honored to earn a place on your speed dial. Demo listing

Five stars all the way. Doug and they installed a Mitsubishi mini-split in our bonus room above the garage, and they picked up after themselves every single day. We've already recommended Doug to two neighbors.

Five stars all the way. Doug and they replaced our 20-year-old furnace right before a deep freeze.

Average overall. Doug and the team installed a Mitsubishi mini-split in our bonus room above the garage, and they wore booties in the house without being asked. Fine for a basic job, not sure for anything complex.

Quality work, fair price. Doug and they set up a whole-home humidifier and we finally don't get nosebleeds in winter, and they made sure our dog was comfortable around the crew. Would call them again without hesitation.

Solid work overall, would use again. Doug and they redid our return air ducts and the difference in airflow is night and day.

Dependable and easy to work with. Doug and they replaced a cracked heat exchanger and explained exactly why it failed, and they took the time to answer every question we had. Would call them again without hesitation.

Phenomenal. Doug and they installed a new variable-speed AC and the upstairs is finally comfortable.

Just outstanding work from start to finish. Doug and they diagnosed a ductwork airflow issue that previous companies just sold us on a new unit for, and they picked up after themselves every single day. Ten out of ten — this is how it should be.

Quality work, fair price. Doug and they added a smart thermostat and walked my dad through how to use it.

We're customers for life now. Doug and they redid our return air ducts and the difference in airflow is night and day, and they stuck to the original quote with no surprise add-ons. If you're on the fence, just call them.

Couldn't be happier with how this turned out. Doug replaced our 20-year-old furnace right before a deep freeze, and the whole crew left the worksite cleaner than they found it. They also left the worksite cleaner than they found it, which we really appreciated. Ten out of ten — this is how it should be.
