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'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.

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 looked long a hard at geothermal technology first and then focused our energies on the Waterfurnace brand, which I've heard and read great things about. Next came finding a local company with the experience and service standards I expected (lots and high level). While I got squirmy answers from other vendors, JK provided the answers I was looking for which in essence is "if something isn't right, we'll fix it". That's every part of the installation. That's important to me as most installers don't cover/handle issues with the wells which is a big part of the cost of installing geothermal.


A few notes on our installation: we went with the 7 Series, which was about a $7-8k premium over the 5 Series which is still the bigger seller. Our system used the Intellizone-2 zone controller to feed air to three zones. We also replaced our water heater and our electrical panel and those costs are reflected in the price above. We also had the extra water tank added to collect hot water from the system. Also included was the removal of the oil tank (yahoo!). Lastly, our price included drilling the two wells (forget the depth, but know they're deeper than the 5 series needed) and a rough grade.


Starting with the salesman, I received very quick and thorough replies from the initial contact thru project startup, when a project manager became my contact. I never felt pressured and always felt he was listening to our needs. We used PA Help loan program and JK worked well with them to get the loans approved. This process wasn't the easiest thanks to some confusion with two loans instead of one, but only needed an extra phone call to resolve.


When the project started, the project manager does a walkthrough to assure we all understand the requirements for the zones, placement of the three thermostats, etc. the company was flexible with scheduling around our vacation. Also, even though they subcontract the oil tank removal and the well drilling, JK does all the scheduling. You will get a call from the well drillers to confirm the times and provide some info on what to expect. Our project manager stayed in touch with us and was there after the install for some minor questions we had. During the install he was there the first day and came back the last to wrap up.


The well drillers were professional and there when they promised. They set up a silt fence to protect against runoff - lots of grey sludgy water when drilling deep. The drilling is LOUD...wear ear plugs and/or headset when watching. I watched a lot because it was a cool process. All of their joints are heat fused, which is the strongest. The trench dug to the house was done to avoid tree damage. They even removed a shrub that was protecting the now-gone ac unit. At the end, the yard is rocky (we have a lot of shale), but evened out and graded away from the house.


The crew who came for the oil tank were quick and efficient and obviously had done such jobs hundreds of times. They dug from the outside to remove the pipes that came in for filling the oil tank. Then they went inside to actually remove the oil tank. When removing they took extra care not to bang walls or make a mess. Finally, they filled the holes in the concrete foundation wall where the oil fill pipes came into the house. They used filler inside the wall and concrete patches a few inches deep at both sides. This is the only part of the job that I asked the project manager to come back and fix. He personally came back with a bag of concrete took off the inside patch remove the filler and fill the entire wall with a concrete mix at no extra charge.


The actual install for everything inside was also done with attention to detail. The person doing my install personally owned a 7 Series geothermal system at his own house, which provided me with some level of comfort with his knowledge of the system. All work, from running new ducts in the basement, to the configuration of the heat pump was done with my requirements in mind. If they weren't sure of my preference, they asked. It was a good crew, and treated me with loads of respect and patience - if I'm spending this kind of money I'm going to ask a few questions. On the last day, when the schedule was tight, they brought in a third man to assist and keep to their plan. The primary two-man crew had one expert installer and one person helping (and getting the experience to become their next expert).


All in all, it was a great investment and one I would only have made with JK Mechanical.

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.

Things went great.  This is the second time I have had them in for major work and I couldn't have asked for better service either time.  The employees were friendly, new their jobs and made a couple of good suggestions that saved me space.

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.
