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.

Professional and timely air conditioner maintenance. Also attentive to personal safety with a mask. We make sure to purchase an annual service agreement which covers the cleaning and check up of our AC unit and furnace.

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.

Two coworkers recommended JNL. So I had JNL install a new furnace and AC last December and they returned in May to check out AC performance. The installation is very professional, the equipment is working great, and the technicians have always been courteous and tidy.

I received an email that the technician was on his way and he was punctual, professional and took time to explain what he was doing and explained the condition of our units. Will definitely use JNL Climate Control again.

We are very happy with JNL. They installed our a/c and furnace 4 years ago. We have them come regularly for spring and fall check ups and they are always friendly and professional and their prices are very competitive. We highly recommend JNL.

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'm very pleased with the service I've had from JNL over the years They came highly recommend to me and I also recommend them to others. Our recent furnace install was preformed professionally and promptly. When I came across an issue that required involvement of the manufacturer, the folks at JNL really went above and beyond for me.I highly recommend JNL for all HVAC and plumbing work.

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!

My heat went out on a Saturday morning and it was a cold one. I called JNL and received a call back from a technician within 30 minutes. We were able to get the furnace back up and running and the house was warm again within an hour or two. Great people. THANK YOU!!!

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.

I had JNL install a new furnace, humidifier, and thermostat on 12/23/19 and was very satisfied. The two installers were very professional and did an awesome job. The owner even showed up to inspect work. I would highly recommend JNL Climate Control!

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.

Extremely professional service. We’ve used JNL Climate Control for more than 10 years and always get knowledgeable, experienced service. We recently had JNL replace our furnace, AC, hot water heater and humidifier. Big job! We are very happy with all the products and service we received. Andrew and Jason were great! Very skilled and conversational regarding every detail. I highly recommend this company for all your HVAC needs.

Service technician prompt and courteous. My furnace is nearing the end of its life, but there is no push from JNL for me to replace it. They are willing to nurse it along. I appreciate that. I have been a customer for many years and know JNL to be very trustworthy.

The plumber was courteous, very professional, and very competent. The work was done in the time he estimated and the price was reasonable. I will be calling him back to install a new faucet 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.

Zach entered the house with slippers and respected every space he worked. He took time to explain the status of my air conditioner, was honest, and thoroughly cleaned the areas. 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.
