Trusted Commercial HVAC Contractors in Cincinnati

Noah did a great job doing our Fall/Winter HVAC checkup today! He was very prompt, checked everything thoroughly and made sure we had no questions afterward. We appreciated his professionalism and kindness throughout. Highly recommend JonLe!

So happy with Jonlee and the technician that solved the gas leak in my furnace. They were able to fit me in and were onsite within 2 hours!! Phenomenal!

Was timely, courteous, and reasonably priced. Provided a clear diagnosis. Couldn’t fix because my system appears to be obsolete 😭😭😭

They have done a lot of work for me over the years. They don’t replace things that don’t need replacing. They give a fair price and do great work

excellent service!

JonLe Heating and Air Conditioning serviced my furnace. I could not have been happier that the problem was relatively minor. They were professional fast and reliable. I will use them from now on. Its hard to trust any company but I feel I have found a reliable source for my needs.

Used these folks for years. Service is great and professional.

JonLe installed a whole house humidifier. They were responsive, answered all my questions, and the customer service was excellent. Technicians showed up on time, were professional, and cleaned up after themselves. I even purchased their maintenance plan. Great company and I’m happy to give them my business going forward.

Called JonLe to fix furnace. Thermostat was calling for heat and fan was running, but no combustion. Technician arrived within 2 hr and identified problem as the inducer motor not working. It had seized. He was able to manually get it turning again and lubricated it to get it running. He recommended ordering a replacement because it would likely fail again. I agreed and he returned next day to install the new one. Furnace is working great. Have used JonLe for 20 yr as they installed the furnace when we built our house. Very satisfied with their service plan on my furnace and air conditioner. Happy to recommend them.

We have a maintenance plan with the same technician for our home and a condo. They are efficient and easy to schedule.

The technician seemed very thorough, explaining everything he checked. He showed pictures of the unit and what he checked and mentioned things to look for. My husband was impressed with his work ethic.

Called at 9am because furnace was not working properly. They had it fixed and running within 5 hours of my phone call. Reasonable price. Great service.

Cory did an excellent job maintaining our heat pump and humidifier.

Matt with Jonle did a great job servicing my furnace and boiler.

Jonle was responsive to our emergency situation. Service tech was thorough and took all steps necessary to solve the problem.

We have been using Jonle for 20+ years. Technician (Mark Johnston) performed our annual furnace maintenance this past week. He was on time, courteous and thorough. Once complete, Mark showed us pictures of the inside of our furnace and explained the services he performed, including changing the filter (I provided) and the humidifier pad. Overall we were pleased as always.

Service Technician Tim Feldman does a great job in maintaining the equipment. Always friendly and has good answers for any question. Maintenance contract went up 18% in 2025.

Excellent and timely.

Todd was great to work with. He was really straightforward about the options we had and what would be the best deal.

I have had our furnace/heat pump check-ups and service done by JonLe (merged with Tri-County) for over 20 years and counting. From the HVAC installers (2/3 units replaced over these years). I have my summer and winter services BOTH done annually, using your Annual Service Agreement. Many of my services have been performed by Technical Engineer Steve and he has "ALWAYS" done professional jobs. He's great at trouble shooting, explaining and a "GREAT ASSET" to the JonLe Company; great skilled professional people with people skills is always a plus for any Company. I have recommended JonLe to family and friends that have also had great experiences. From Dave, Dennis, etc who installed my latest HVAC unit in recent years unit to Steve you have quality experienced staff. Again, Steve is a GREAT asset to your Company and one reason, I have continued service with JonLe; and recommended your Company to family and friends. Other HVAC services constantly are trying to expand their business with less expensive deals, etc. but I have remained a satisfied loyal customer; feel very comfortable that our HVAC system is always in top condition. I do wish everyone at JonLe a GREAT end of year Holiday's too; stay safe and well!

Quick response and follow up

Matt was great, did a great job, professional and fast

I have used JonLe Heating and Cooling for a number of years at me previous residence and now at my current location. They have always given us the highest quality service and professionalism from installation of a entire hvac system to yearly maintenance. I have always highley recommended them to friends and family.

We called Jonle because our furnace was not producing much heat. A technician came by the same afternoon and fixed the problem. He was professional, courteous and extremely knowledgeable. He took the time to explain the problem to us and answered all of our questions. Highly recommend! Good folks!

Timely response and great service, highly recommended

Great experience. I called Jonle because the previous owner of the home had their maintenance done through them, and figured if anyone would know my furnace it would be them. The tech (Tim Feldman) called roughly 30 minutes before arrival. He was friendly and was able to diagnose the issue with my furnace quickly and able to explain to me what was wrong and what the fix was. He was able to get my furnace running properly quickly, which is a life saver during the winter!

We have used Jonle to preform our annual HVAC maintenance for several years and to install our new furnace and AC. They are very professional, knowledgeable and dependable. I would definitely recommend them!

JonLe installed our furnace, house A/C, and an additional A/C unit for the upstairs bedroom. They come annually to do a checkup. Friendly employees, professional work, excellent service.

Mr. Sheppard did a FANTASTIC job. He took his time, was happy, friendly and respectful he explained what he was doing, explained our humidifier, air cleaner and thermostat (we just moved into a new home and no papers were left.) We would like to have him our system in the spring.

I really like Jonlee because of their professionalism during my regular seasonal checks for ac/ furnace . I purchased my furnace from them years ago and I was pleased with them giving me comparable products and prices to choose from with a patient and seamless experience. Jonlee has always shown me and my home respect by arriving on time and their cleanliness.They always arrive with shoe covers . Their service is reliable and costs are reasonable which has the same furnace running for years.

I had a broken furnace that was unsafe to run for the upcoming winter season. JonLe was the second company that I called to get a quote from and they were much more affordable than the competition. They were quick to get me the quote and gave me plenty of financing options to choose from. The scheduling was effortless and the installation was quick and professional. I'm so pleased with my new furnace. <3

Jason did a great job of checking and cleaning our system!

Great service, on time, very affordable. Thanks for keeping us warm!

I have been a client of JonLe for the past 20+ years; they are awesome. Because of their regular maintenance on my system, the life of the unit was extended approximately five more years than expected. Great company!

Tech was very quick and knew the problem right away.

On time. Knowledgeable and friendly technician. Been using Jonle for well over 25 years. Use the Silver Plan to get both heat and AC maintenance.

Steve Rains provides fantastic service!

Great service today by Matt. He was very thorough and friendly

Professional and easy to work with.

JonLe is a great company! They have been there for me whenever I've needed them. That's loyalty to their customers that you don't see very often anymore. Good job JonLe!!!

We had our furnace/heat pump winter check and service done by Matt, he was great, explaining what he checked and offering details about how well the units are running and that we were ready for the winter season. We have used Jonle since we moved to our new condo in 2016 subscribing to their Energy Savings/Preventive Maintenance Service Plan. It provides twice per year check up services by their friendly, knowledgeable service technicians. They explain what they have cleaned and checked and how your units are running which is helpful. The few times our unit needed a replacement part or repair, it was explained clearly; the repair was done promptly and the pricing was very reasonable. With Jonle, we feel very comfortable that our HVAC systems are always in top condition.

Been with JonLe since 1999. Very responsive and very good service. Wil and Tim the techs have been excellent .

Great service. the technician came punctually. Very friendly, very knowledgeable. Great service, no complaints.

Great service. On time with clear communication through the whole process. Great company!

Every technician we have encountered over the years has been friendly, competent, and thorough. It is very reassuring to know that someone is keeping an eye on our system to spot issues before they get worse.

The price that I indicated covers me for 12 months and two maintenances each year. It also results in reduced costs if I do end up having an actual problem as well as I promise that somebody would be at my home within an hour.

Excellent service performed by your technician. Heating maintenance on my 24 yr old system which Jonle has kept running flawlessly for that time.

professional, friendly, on time. Explained everything

Replacing an entire HVAC system is incredibly stressful. Not just because of the cost, but also the fear of being taken advantage of or making a really bad situation even worse. Our experience with JonLe, however, could not have been better. We would gladly give this review 10 stars if we could. First, Frank (a former installer now in sales) and our lead installer, Jared, have been with the company for 30 and 16 years respectively. Their experience showed immediately from the first visit. They pointed out simple improvements to the water line for the humidifier plus the ductwork with ways to increase airflow that have already made a huge difference in the performance of the new system. The price, warranty, and service agreement were all better than the four other Cincinnati companies we spoke with. JonLe also offered the most favorable financing terms on a new Carrier system, along with helpful information about a tax credit we can claim before the end of 2025. The best part of the entire experience was the installation by Jared and Sam. It took three days because they took their time and did things right. I’ve included photos of their craftsmanship. Thank you for turning a VERY stressful situation into a much easier one. Both in terms of the final product and the cost. You truly exceeded our expectations.

Noah was on time, checked furnace and explained what he was doing. Very satisfied.
