Geothermal Services

JK Mechanical taps into the free energy source buried in your backyard. We take advantage of stable temperatures underground, in a pond, or well, to keep you comfortable while minimizing monthly costs. Geothermal heating and cooling operates on electricity but relies on the earth’s thermal energy to maintain perfect year round temperature in the average-sized home for a dollar a day.

What Our Clients Say

“A tale of two service calls. 15 years ago JK Mechanical installed two geothermal units in our house, replacing our old oil burner. Back then, they were pioneers in the area in geothermal, and great to deal with! A couple of hiccups in startup, but they stood behind the work admirably. Fast forward to last week, the cooling stopped, and we had family coming in to visit. Had to get it fixed so I called JK and was scheduled for the next day, 8/29. The technician got to our home, and I showed him the unit and explained the situation. First was the thinly veiled chastisement and guilt fest for not having a maintenance plan in place, and after that was over, I asked “yes but can you fix it?” He asked for a moment to look around, so I left him with the unit. After a few minutes he called me down and said the refrigerant was low and he would need to do a leak test and replace some expensive parts and presented me with an estimate to sign for around 4K. I said for that money I’d better look at a new unit. I then asked him as a stop gap measure (it was hot) what would happen if we replaced the refrigerant and added a stop leak as they had done a couple years ago to the second unit in the attic. He said it was a “gamble”, but he would write up another estimate. A few minutes later, he produced another estimate for 1900 bucks to add 6lbs of refrigerant and stop-leak. At this point I realized this tech wasn’t going to repair anything and feeling a little scammed I said why don’t we part company, and I’ll pay you for your time. He put the panel back on the unit and said he needed to go to his truck. After about 20 min. I went out to the truck and said can I pay you; I need to leave. He presented me with the final bill for $309, which included his extended diagnostic charge. I signed it and drove away. That evening, I called my plumber and asked, “who do you know?” He said he would use Constant Comfort Solutions as he really trusts them. Long story short, they were at my house the next afternoon. I left Hunter, the technician from Constant Comfort Solutions with the unit and within 15 minutes he showed me a pic of where the leak was, said he could solder it up and add refrigerant for $749. About an hour later it was done, Hunter was paid, and the house is cool again. I know my geothermal units are near the end of their expected service life. And I’m sure JK has many satisfied customers. But based on the difference experiences of the back-to-back service calls last week, we’ll be moving on…”

“I want to write a review in regards to Mr. Steve Moyer that came out to do the yearly maintenance on my generator. Mr. Moyer was excellent and knowledgeable. He was attentive to my all questions and went through verbally everything he was doing to the generator with me. He took the time which I found to be very valuable and excellent customer service. Please make sure he is the maintenance guy you send out to my house for future upkeep a service.”

“JK Mechanical is an amazing company! Recently, following a downed tree on our property during a severe storm, we needed to have our electrical meter reinstalled on our home. Their service, from beginning to completion of the job, was professional. Steve and his team, Ashley and Jen in the office, all assisted with getting the job done and in a very timely manner during a trying situation. JK Mechanical went the extra mile and beyond. I would highly recommend this company for your electrical needs.”
