I have been a customer of JK Mechanical for over 20 years. In my opinion, they started out great, but lost their way. This review is about the service I received about fixing my 15 year old mini-split unit. History: The outdoor unit is located on a flat roof. I recently had the roof redone and the roofer told me they had to lift the untit six inches to get the new roof material under it. He warned me that this could cause a leak. A very slow leak, but over the course of a year, the unit worked less and less until it finally would not provide hear or cooling. I agreed to have have a technician come out to evaluate my unit and estimate the repair cost. The charge was $150 The technician arrived and inspected the equipmen. He told me bad news. 1. The system was FLAT, meaning that all the refrigerant leaked out. 2. The system uses outdated R22 which is no longer manufactred and remaining stock is very expensive at $300 a pound 4. My system requires 5 pounds so the cost of the refrigerant alone would be cost prohibitive at $1500. 5. The technician called the office to see if they would give a repair cost. They said No. The system is unrepairable. I was ready to install a new minil-split. I got 3 estimates, all around $5000. JKs estimate was $2500 higher. I decided to call another company and they sent a technician out. This is the interesting part! A. He inspected the outdoor unit and said it was obvious where the leak was because of staining at a flair nut. B. He said the system was NOT FLAT and still had some pressure so that evacuation would not be necessary. C, He said that there are drop-in replacements for R22 at reasonable cost. D. My system requires 2 lbs, not 5lbs. He tighted the nut and charged that system and charged me $400 In conclusion, My "unreparable" system was fixed and is working properly for $400. I called JK Mechanical to inform them that I was unhappy and wished to speak to someone in authority. They gave me the human resources person. I explained that their web site talks of unparalled knowlege and expertise, and that my experience was not that. I explained that the JK tech said the system required the outdated R22, but did not tell me about drop-in replacement options. He said that system was flat, and it was not. He said that it required 5 lbs, when it actually requires 2lb. He said that the system was not repairable. It is repaired and is working fine for the last two months. I told her that I was not renewing my service agreement for my home's main HVAC system and that after 20+ years, I was leaving JK Mechanical because my confidence in them was lost. She said that she understood how I felt and would pass along my comments. After paying a service agreement for over 20 years, I thought that recieving a follow-up call would be nice and the mark of a customer focused company. I was wrong. No communication. My confidence in JK is lost. How can I be sure that if my main system breaks, that I'm given the correct advise. The other company earned my business. read more

Terrible I have spent close to $40,000 with this company over the last 25 years having a geothermal heat pump system installed and then replaced with a new system, along with other plumbing projects. Last week I had a water heater that started leaking and was under warranty. Technician stated that I would only pay for labor to replace. Technician was there less than 3 hours and my bill was $890.00. Called to ask why bill was so high and was told they charge $189.00/hr and the rest was for "storage of the water heater and pipe fittings". So $300 to store a water heater and a few pipe fittings in addition to a rate of $189.00/hr Absolute highway robbery Never doing business with this company again read more

Used to be much more responsive, competitive with better service people. Paid them lots of money over the years only to find out they missed some important electrical issues in my heat pump. Paid them a fortune to come out time and time again to find out what the problem was, and they never could. Issue solved when I bought in someone else, who finally diagnosed the problem correctly. This is a vey common issue with businesses in their 2nd generation of upper management. If your comfortable trying one of the "big electrical companies" , I'd try someone else. read more

They used to be responsive with good work at fair prices. Now they do not even pick up the phone to service a generator we paid them $20,000 to install. Greed rules! read more

JK Mechanical's CHRIS JONES, resolved a very long standing HVAC issue in our home. Chris determined that the equipment needed to have refrigerant added (not inexpensive) and ducts in the attic crawlspace replaced. Michael replaced the faulty ducts - heated or cooled air was escaping into the crawlspace rather than getting to its destination. After living in this residence for 28 years and having three other HVAC companies service our units, plus having replaced failed units, our home now holds the temperature that the thermostat is set at. I could not be happier. I just hope the freon doesn't escape! read more

I've used them in the past with very mixed results. I had one of their HVAC folks out for 5 hours trying to diagnose a heating issue with a baseboard upstairs in my home. He couldn't figure it out. Got charged $400. A year later, I got fed up and hired a different company who diagnosed the problem and bled the entire radiator system, fixed the issue. read more

Excellent service, great products. Got a gas boiler, works well, efficient. Jake the service tech was very helpful read more

Wish I could give them a better rating but I can't. They flat rate their HVAC repairs quote based on so many hours to do the job and then they come out and do it in a third of that time - but charge you for all the hours anyway. Furthermore, I have found their products to be unsatisfactory when it comes to ground source heat pumps. WATER FURNACE is their brand they push. That is because you can only buy parts from them for this make. The unit they sold me failed after six years and had to be replaced.There are far better ground source heat pumps on the market that do not force you into a parts and service monopoly. read more

JK Mechanical is a good HVAC business to work with. They installed our geothermal heating system a few years ago and have performed our twice yearly service on the unit since installation. Their technicians are courteous , friendly and very professional. We are very satisfied with their service read more

Excellent service! This company came the same day that I called. Tom explained to me how the user interfacer works and it helped me to better understand the system. He also explained JK Mechanical's Service Contract which is well worth the money. I feel that this company is very service oriented. I highly recommend this company if you need a new air conditioning system. read more

Jim S. was on time and called to say when he would arrive. He checked out the problem and had to put in a work order to have the repair done later due to needed materials and equipment. Mike L. called to say he was on his way and arrived on time and went right to work on the repairs. Mike has proven his abilities as a knowledgeable technician in previous work and I was grateful he was assigned this task. read more

These guys were awesome. We hired them to install our geothermal system and they were amazing throughout the entire process.
