I'm a homeowner and a general contractor. I had a hard time finding good quality HVAC company to perform furnace maintenance. JNL came recommended from one of my customers. I called JNL and was surprised how easy and efficient the scheduling process was. They put me on their schedule and followed up with email as promised. On the day of service I received reminder call. The crew showed up on time, they were professional, knowledgeable, inspected and cleaned the furnace. They also offered me few options on future pro active service, which I accepted. The furnace is running smoothly, quieter and more efficient then before. I highly recommend this company and plan on using them in the future.

Called later in the evening with an AC problem and left a message with their service. I promptly received a call back at 8:05 in the morning and they were able to schedule a technician to my home the same day. He arrived promptly within the service window they had stated. The technician(Zach) was able to answer my questions confidently and professionally. He diagnosed my problem and offered a temporary solution while a quote for parts and labor were being prepared for more permanent repairs.

Can't recommend JNL enough. We recently moved into our home and quickly discovered we needed to replace our HVAC. We received JNL as a referral from a family member. Kurt was a pleasure to do business with, and has been working closely with us to provide details to our home warranty company. Their technicians are experienced, professional and friendly. Highly recommend JNL!

Kurt’s team of technicians are always prompt and professional. These are people you feel comfortable having work in your home. I would recommend JNL to anyone for basic maintenance, repair work or system replacements and upgrades as they are mindful about costs and always deliver value with their recommendations. Not everyone can check all of these boxes like JNL does.

Very friendly and professional service performed on my AC system that went out suddenly. They worked hard to accommodate my crazy schedule with sending someone out to fix it. I definitely will be calling them again if more service is needed. With boiler heat and 2 AC systems im sure it won't be long.

Highly recommend them for heating & air conditioners. Did such a great job for my condo that we used them to replace furnace at my parents' home when basement flooded. Excellent service for simple maintenance too - have them out twice a year to make sure everything stays in tip top shape. Just had a/c clean-up today & whole place even smells better!

Watching TV last night and the house seemed warm. Went to check thing out — first the thermostat, then the HVAC in the basement. Looked like the fan was not going on. Called JNL this morning and I’m now sitting in a cool house. Very satisfied with the prompt, friendly service. And a real person answered the phone!

We recently moved to our house and asked JNL to complete an annual maintenance and install a Nest thermostat. The technician that came out was great. Very professional and courteous. After installing the Nest, he walked me through the set up (including iPhone app) and showed me how to use it. The annual maintenance went smooth. Overall great service and very reasonable prices. We will be using them again in the future.

Extremely professional tech they came out. He could have done what I thought was wrong and charge me an arm and a leg longer other companies that I have used in the past. Instead he found the root of the problem with my unit that three other companies have missed. I highly recommend this company and will continue to use them from now on. Thank you for your honesty and hard work. Air works 100% better.

I value JNL so very much. We have used them for 17 years and they are always quick to come right out. For years we have had Andy and value his insight on how to handle repairs when needed and our cleanings. Respectful of our home and took proper measures with PPE during this Covid 19 times we find ourselves.

My last 3 visits I have had parts replaced as my heating and air conditioner and they are 10 years old. I plan that being proactive with a maintenance schedule will extend my units while giving me peace of mind .

We had JNL replace our air-conditioning unit. From the first contact they have been professional and helpful. They did the work in a timely manner and even came back and replaced our air conditioner circuit breaker. We have nothing but positive remarks for their service and feel we have gotten the best value for our money.
Our 33 year old furnace finally quit on us in the midst of a global pandemic. Kurt (the owner) quickly came out and assessed our situation and had Kevin install our new furnace the next day. The entire team was responsible, reliable, and respectful of our house and our safety during this time. We will absolutely be referring JNL to anyone looking for a similar service.

Andrew, our JNL installation tech arrived on time, not only very professional but also friendly. He answered all our concerns and was very patient with all of our questions. He did a wonderful and thorough job not missing any details the installation of a new furnace. He was very careful to put down drop tarps and the clean up was great. He wore covers on his shoes each time he entered into our home. We would recommend JNL to all our friends and family. New have also had plumbing work done by JNL and Paul gave us the same attention as did Andrew. Thank you JNL for giving us assurance that when we call for help you are there 24-7 with a great team of technicians and all the follow up you provide.

I came home from a business trip to find the furnace no longer working. I called JNL and received a call from the On Call Technician within 10 minutes. After reviewing options, it was determined that a new furnace was needed. Curt came out the next morning and presented options, gave an honest opinion of what was best, and told me he could have a tech out the next business day to perform the install. Andrew was on time, very professional, and got the old furnace removed and the new furnace up and running in a few hours! JNL Climate Control is AWESOME and I would recommend them to anyone!

I've been a loyal customer of JNL for a few years now. My furnace fan induction motor was starting to fail. Andy came out with the replacement part and had it changed out quickly. It really helped getting a preferred customer discount as every bit helps. I highly recommend that you sign up for the annual PM program for your furnace and AC. Great company, owner, and employees.

Great experience with JNL for my full HVAC system install in August. Equipment was 30 years old and original to the house so we had a new American Standard AC and HE furnace installed along with a whole home humidifier. They were very professional, on time and did great work. Kept the work area very clean and explained everything they did. All work was completed in one full day as promised. Very reasonable price compared to the various other companies I had out for a quote. They also did some plumbing work for us and we were very happy with that as well.

I have been a customer of JNL for over 15 years and I have found the technicians to be knowledgeable and very helpful. I have had on two occasions the need for a technician to return after a service call was completed and I never felt like I was inconveniencing them. I was reminded that I am paying for a service and they want to ensure 100% satisfaction. The office staff tries to give you the earliest possible appointment, but if they are booked they explain why.

Replaced my air conditioning unit & heating furnace at my home. Service & professional both superb & price competitive. So replaced both at my rental house as well. Outstanding!So many companies to choose from, but the difference for me was owner of JNL Climate Control. Honest, reachable, was calling on a neighbor when we met & my air conditioning was out. Not working again after a paid service call from another company. John from JNL Climate Control did an emergency repair on a very hot day immediately. Followed up with very competitive quote & no charge for giving me temporary air conditioning on hot day! WOW!!!

JNL has always been a class act. I called them yesterday on a Sunday with an in operable air-conditioner. I wanted service for Monday since I was not going to be home yesterday. They tried to come out right away to fix my unit but I told them Monday was fine. The technician came out today and was very professional and efficient and took care of my problem right away. He even took the time to clean my air conditioner which was not requested at the time I placed the call. He gave me a courtesy call when he was on his way and was very punctual. Their prices are very fair and beat out their competition. I would recommend and have been recommending them to everyone I know. You won’t be disappointed!

Having been serviced by JNL Climate Control for 4 years I was very happy with the swiftness of them in replacing my A/C when it died during a heat wave recently. The servicemen were very knowledgeable & considerate of my property. They cleaned up completely after installation of both the A/C & furnace. I highly recommend this company.

We have used JNL for a couple of years now and I am so glad that we switched companies! Their office staff is very nice as are their technicians. Our tech arrived earlier than expected, but he did call to confirm that it would be okay. He did a great job checking the system, cleaning the outside unit thoroughly and leaving everything in order. I love how the techs with JNL always wear shoe covers too. This is an A++++ company.

I appreciated his honesty and certainty about what would be needed in the future. Thank you for bringing me comfort in the temperature and financial expenses. I recommend JNL climate control to anyone looking for honest and dedicated workers.
