Received a quote from Jim for a furnace install, tried to set up an appointment with him, but he would never return my call nor answer any messages. Completely ignores potential business opportunity. It's unfortunate for Rons mechanical.

Make sure you ask for one of their experienced techs, they have a couple of space ghosts working there. On a good note responsive, showed up when they said they would.

I have used Ron's Mechanical several times and have always had a more than satisfactory experience. Tommy, the technician who replaced the blower motor on my furnace, was very friendly and professional. He also offered advice on how to extend the life of this motor. Thanks Tommy!

Tuesday late afternoon my AC went out! I was referred to Ron's and messaged through Facebook- I received a response shortly thereafter! The next morning Greg arrived right on time - did some diagnostic testing and told me my compressor went out! He replaced it and when he handed me the bill I wanted to give him a huge hug! Since COVID-19 our financial situation has changed, and not for the better. Greg was so pleasant, he even enjoyed meeting my cats! I'll definitely be calling Ron's to get my furnace tuned up for Winter! I highly recommend Ron's Mechanical!

I've been using Ron's Mechanical for about 3 years now for yearly AC / Heating Tune Ups. They are always friendly, on-time, and very competitive with pricing. Everyone who has showed up so far has been very informative and explains everything that either has to be done, needs to be fixed, or has been cleaned etc. When I eventually need a replacement unit, I won't hesitate to hire them.

A++! We needed our gas fireplace serviced and Ron's was the only place that could get us on the calendar quickly. Fixed fast and super reasonable price. Use this local company, they were great!

Ron's Mechanical always goes above and beyond! The day before my son's grad party, our AC was running very minimally. It couldn't keep up with the crazy June heat wave. Even though they were swamped with service calls, they sent someone over and quickly added two lbs of coolant to our unit! Just what the doctor ordered! It saved our party prep and our party! Thanks to the office staff as well for being so friendly!

Tommy was an amazing technician that we had! He was very professional, answered all of our questions we had with great knowledge! Our A/C has been blowing warm air these past weeks especially during this hot humid weather and we needed it fixed asap! Tommy came and got our A/C fixed in a timely manner. We definitely don't regret calling rons mechanical and thankful we met Tommy! We definitely recommend the services to anyone who needs work done. Great customer service as well!

WE had Tommy, the service tech. Last spring he caught a defect in our furnace and warned me to get it checkedearly in the fall. Good thing. It got "red tagged" and we could replace it before the heating season began. Next, they repaired a furnace at the very small church where I work, doing the work for exactly half the other bid. Exact same piece, and labor at half the cost.

And then they recommended redoing a too small coil that should have been replaced when another company installed an A/C unit. Again, Tommy came, did the work quickly then came back in the spring to check the pressures and get us ready for summer. Instead of showing me how to clean the outside unit, he stayed and finished the whole thing. I don't think I'll ever call any other company. And their tech, Tommy, is the best!

Greg Anderson came to my place to help fix my furnace. My furnace would turn on and off and just quite working for many hours. When he got to my place and I explained the situation he knew exactly what it was and had it working within minutes. Greg was also a very nice guy and explained how it worked and what can be done to prevent it. Will definitely recommend and use them again.

My AC froze up the day before going on vacation in June 2015. Ron's Mechanical came out the same day to resolve the issue. Completely stress free. The company also quickly replaced our furnace 1.5 years ago during below zero January weather when the old unit failed. They provided space heaters for us until the furnace install was complete. No issues at all with the installation and it has been working flawlessly since.

Working with this company is a joy. They bend over backward to help and resolve issues. Eventually a new central AC unit will be purchased and installed. I expect to purchase and have installation by Ron's Mechanical.
