Technician arrived on schedule and proceeded to prep my A/C for summer use. He did a great job and left my yard clean and neat. The unit works great. I won't hesitate to use them again and recommend them to other neighbors who might need a qualified tech to work on their A/C.

Jack Smith came by to look at our unit which was not functioning properly as it didn't cool. He fixed it for less than 15 minutes! He was very courteous, wore a mask and even put on shoe covers when he entered the home which was greatly appreciated since we have a newborn in the house. We couldn't be happier with the service. Highly recommend!

Jack and team came out on a less than 1 day notice as they were wrapping up the day. 5 other companies told me I had to wait until the morning. Jack explained each troubleshooting step, found the root cause quickly. Repaired on the spot and charged a very reasonable price. I will definitely hire again. As a matter of fact, I signed up for the maintenance program.

Jack has done a fantastic job maintaining the HVAC system for our church multi-building campus. His pricing is more than fair especially considering the high level of service he provides and the expediency with which he provides it. Friendly and knowledgeable--a tough combination to beat.

Out of trying to call local Clinton companies, Home Advisor provided us with Smith Mechanical (Local also). Professional, curious, even same day and on time. Repaired same day and more than a fair price for the repair on our Gas Fireplace. Thank you Jack and Staff.
