As always the technician was on time, personable, professional, competent, and did an excellent job. I have been a customer of J.K. Mechanical since 1988 and was never disappointed with their service.

I'd give them an A on everything or I wouldn't continue to be going to them.

I've been using them for almost thirty years. I have them come out twice a year. They have what they call a comfort plan which gives you a premium, so for twice a year it's like $250. I wouldn't continue to go to them if I didn't like them. They've always been very responsive to whatever I need. They replaced our system once at a very competitive price.

JK Mechanical worked with me through the entire process, answering my many questions and taking my preferences into account when recommending a solution to replace an old heat pump with a failed compressor with an entirely new, highly efficient Carrier system. The work was performed promptly, professionally, and cleanly - I am happy with all phases of my interaction with them. Price was a little higher than I (perhaps naively) expected, but on par with other quotes for similarly energy-efficient systems and should easily be recouped in energy efficiency savings over time. Would use them again in the future for sure.

This company was a joy to deal with. I can, and do, wholeheartedly recommend them. We talked with many different geo companies and they were miles above anyone else.
The only issue with them was that they subcontracted the drillings of the geo wells to Eichelbergers. Personally, it
 is ok that they subcontracted out the drilling, it is just who they did that with. If I knew what I know now, I would have asked if they could have used anyone else.
The driller aside,I would still use JK. They were courteous, responsive, and very professional throughout. I don't know how many other ways to say they were awesome, so I will just leave it at that. They were awesome.
Response from JK Mechanical
"[Member Name Removed], With a month under your belt I trust that all things are going well with your new geo equipment. We appreciate your comments, but mostly we are glad you are on your way to lowering the operating costs of your home for many years to come."

The salesperson did not always call back when he promised to but otherwise all went very well and we feel glad that we now won't have to freeze like we did the last time the power went off due to a winter storm.  The work was done by two knowledgable workmen, Gordon and Tim, who were friendly, courteous and efficient. They thoroughly explained everything to us. The unit was installed exactly as promised. We have not had a power outage yet since the install but the unit tests itself once a week as it is supposed to and all seems to be in order and it looks good. I have since called this company for other HVAC repairs and have been similarly pleased with their work.
Response from JK Mechanical
"Thank you for your review and affirmation. We continually seek to improve the experiences of our partners and I have passed along your comments to our electrical team. We wish you the best and are quite confident that you will be most pleased with your automatic stand-by generator. They perform wonderfully."

We purchased our current home in June 2014. JK Mechanical had installed a new heat pump/ac system in the house in 2012. The system needed checked so we called JK since they installed it. The appointment was scheduled forAugust. The technician called to let us know that he would be arriving soon. He was courteous, professional and thorough. He checked the system completely and fortunately everything was fine. He offered us a service contact which included the tune-up for the AC plus a tune-up for the heat pump in 6 months. The price for the contract was $263. We agreed to purchase it. I thought that the price was high but figured since they installed the system that we should stay with them for service. Plan on doing some reseach into pricing for tune-ups from other companies. We made an appointment in January to have the heat pump tuned-up. Again, although a different technician, he called to let us know that he was on his way. He also was courteous, professional and thorough. Overall it has been a positive experience with JK Mechanical and we would recommend them to others.

I was very happy with JK Mechanical, from start to finish. Their driller, Myers Bros, worked in some difficult weather conditions in December to complete the drilling, and then the installation was completed the week of Christmas for the pump, desuperheater, and water heater.  I was on backup heat the first day, and completely running on the geothermal heat pump by the end of the second day.  Everyone was very prompt and professional.
My salesman suggested a different thermostat than I'd originally chosen because the service department wasn't impressed with the way the original one worked with the geothermal heat system.  I noticed after the first or second day that the backup heat was coming on a lot (uses electricity to operate, so quite expensive), and mentioned that to the installers, who were still there working on the water heater & some vents I'd chosen to add.  They adjusted the thermostat so that the backup heat, instead of coming on for comfort, would come on only if the temperature differed by 2 degrees from what was selected.  Immediate fix!  I believe this thermostat was new to the installers, otherwise I'm sure they would've set it that way right off.

The serviceman was very professional and knowledgeable. Appreciative that JK Mechanical was able to come out within 24 hours since the weather was so frigid.

Professional from start to finish. 
Site survey was thorough, they explained everything, answered all questions.
Price was consistent with others except they guaranteed we would receive a $7,500 rebate from the state. That tipped it for us, but after working with them, guarantee or not we would have retained them.
Installation was smooth, excellent communication.
Follow up has been excellent. They actually monitor our system on line and recently called to ask to come out a take a look at it. They thought we might have blown a fuse due to a lightning strike. They came out, confirmed the issue, fixed it and sent no bill.
We have worked with a lot of contractors over the years and none have been better than JK.

Everything was excellent. They were efficient and on time. They cleaned everything up very well. They made for a smoothy transition from oil to gas. Also, I had recommended them to a friend earlier this year, and she was extremely pleased with the installation of her gas furnace and water heater.

I'm not happy with them at all. I’ve been using them for 13 years and they screwed me around too much. Well they sold me what they call a maintenance program where they come out in fall to check your heater and the spring to check your air conditioner and clean it and check everything if okay. You don’t have to pay for that it’s a one time package deal and you pay so much for both services and I said to the guy I had the service before and I said now are you going to call me and remind me or call me with the appointment or do I have to call. They said we will get hold of you and I said are you sure because last time you didn’t and when I called it was too late to do my fall service and you said well that’s too bad that you just out that money. He said oh no we won’t do that well they did that again so I didn’t get my follow up service last fall and now I have to call him now for my spring service before they don’t call me and then I’ll be out that money. There are not holding up from what they promise. They came in to clean my air duct and took my vent of the wall and ripped drywall and mess up my paint – they just cement it and tried to cover it up and the one vent they were suppose to clean because I’ve complained about it and instead of cleaning the one vent they just took it and replaced it with a cheaper vent they had in their truck because my vent knob open and close them or flash vents because I’m in a wheelchair. I mean everything that they’ve done they’ve should I say half-half you know which is not right and because I’m a single woman in a wheelchair they think they can get away with it. I have to use them because I have that contract for the cleaning for the heater and air conditioner because I paid for it. They installed everything in my home when I moved in. I built this place 13 years ago so it’s really disappointing but I have to use them again to finish the contract and after that I will not be using them again.

We had a really good experience after a bit of a rocky start.  Our salesperson was there for us from the first to the last.  He stayed in touch, answered all my question (and there were a lot of them) and responded to my calls and email in a very timely fashion.  The first day the crew was to come to start the install, no one showed.  But they made up for it when they came the next day.  Even the sales person showed up to over see the operation.  They finished the install that day!  I have to say that despite the glitch, everything really went well and I must especially hand it to the sales man who was there for us all the way.    
    I was very pleased overall, and would use this company again when I need service for other equipment that we use to operate this household.
