Reviews of local pros in Cincinnati, Ohio

Matt was beyond professional and his attention to detail is unmatched. Not only professional, but personable to the point we will miss his presence like a good friend! I work as a chief engineer at a Hilton Garden Inn in Mason and all we use is Jansen at our hotel for all of our HVAC needs and they excel with their work at the hotel also. Would highly recommend this company. Everyone we spoke with exceeded our expectations with professionalism. Five stars

Very responsive for weekend service! My A/C died while I was away and it was 90 degrees inside. I called Jansen at 6pm on a Sunday and they had someone at my house within 90 minutes. Jeffrey fixed the issue and waited to make sure it did not recur.

We had Brayden R come out for our visit and he did a great job! He took his time and checked everything out, he truly went above and beyond. I felt like he was being so honest and he just gave me a trustworthy feeling about his diagnosis.

I can’t imagine using any other Heating & Cooling company than Jansen!! I have been a grateful customer for decades utilizing their Club Membership…I know when Brett comes to tune up my air and furnace, the job is professionally completed and I can rest easy until the following year when he arrives again. Peace of mind is a huge comfort!

Stephen is very knowledgeable and shows attention to detail and a commitment to excellence in all aspects of maintaining my two HVAC systems.

May, 2025, Stephen suggested adding 3 lbs. of refrigerant and stop leak. The repair cost was $700, but I don’t have the money to replace the air. I’m prolonging the inevitable. In 2024 Justin told me my air conditioner was leaking fluid. It was 15 years old. Duke records validate it was using more electricity compared to previous year. Jansen has kept my Carrier furnace running perfectly for 26 years. Very honest and trustworthy company! Fine people working there. I have to ponder replacing both, but I’m hesitant now because of refrigerant change. I trust them to tell me the truth.

Feb., 2014, the coldest day of winter, my furnace went out. They came in the middle of the night and tried to fix it. The heat exchanger died. They could have tried to sell me a new furnace then. Instead they told me it was a manufacturing recall and under warranty. It cost me nothing to replace. I couldn’t do business with anyone else!

We were very pleased with the service Justin provided. He was very polite and knowledgeable. Plus he didn’t try to badger us into buying a new unit even though ours is 30 years old. He did give us some suggestions when we’re ready to buy a new one. We will definitely call Jansen again!

Tom was polite and professional. He offered their membership perks and other services that may benefit us but he was not pushy. He also came out on less than a day notice to check our carbon monoxide. Very positive experience overall- we may see them again soon!

Representative Stephen Davis did a wonderful job of diagnosing the problem. His kind and encouraging attitude made the visit excellent.

We had an old and failing central AC system in the house we just bought and we hired Jansen to replace the whole system. They helped us choose a system that works best for us, at the best price. DJ went above and beyond with explaining what system he would suggest for our house and spent time talking about the benefits of different options. He was very prompt on answering any questions we had before the install. During the install, the workers found many unexpected issues with how our old system was installed (incorrectly and not up to code) and they were able to fix everything for the new system and do it right. They were very helpful with explaining everything throughout the whole process! They also spent time cleaning up everything after they were done and you couldn't even tell any work was done once they left (other than our house was finally cooling down). I would trust them again for any of our HVAC needs going forward. We got quotes from multiple other companies and Jansen was the only one we felt weren't trying to nickel and dime us or trick us into getting a more expensive system. Plus, they were able to get us scheduled quickly for both the estimate visit and the install.

Brayden was outstanding! He knew my system well. He used his diagnostics tools to show how my AC was performing. The bottom line is my 2 story home with a basement will struggle to cool the 2nd floor on very hot days. Unfortunately, very hot weather has become a regular occurrence and I may need a 2nd AC system to achieve the level of comfort I would like on very hot days.

Stephen Davis was my tech today. It was so hot and I was at a loss when the AC capacitor suddenly went out, and then we were quoted close to $1500 upon initial diagnosis. What can you do? It's summer, and you have to get it working!

One of the parts that was needed was back at the shop, so he had to return back and then come back to the house to finish the job. About 20 minutes into the repairs, I heard a knock at the door, and it was Stephen, huge smile, despite being drenched due to working outside in the heat, to tell me one of the parts he was sure needed replaced was actually working fine. And, it was actually an issue with some wires that were inexpensive to fix, compared to the $700 part I was expecting to pay for. Despite this, he still gave me the option to either replace the part, or to hold off. He then told me the shop could hold on to the part for a few days, in case something did go bad, but that he felt pretty confident that things were running great, so I decided to hold off.

In the end, the entire job still cost close to $700, but I also saved $700 because of his honesty and expertise. We've had Stephen out here before, and it's always been a positive experience. Today, he went above and beyond. Give this man a raise!!!!!!!

Jansen is the best. Super reliable and fair prices. Today’s fall tune-up was smooth and professional. Stephen and Robert were extremely professional.

Steven D. with Jansen Heating and Cooling did a super job in identifying and solving our AC resonant frequency noise/hum issue. He is the most knowledgable and thorough technician for difficult issues such as ours. Thank you!

I called Jansen with a down system. Christine, their dispatcher, was able to get a tech to my home later that same day. Their tech Brett L. quickly diagnosed the problem, got parts on order and had the system repaired the next morning. Courteous call agents, great technicians and overall a great experience. So impressed I signed up for their maintenance program. Would definitely recommend Jansen.

I had an excellent experience with Devon from Jansen Heating and Cooling! He was incredibly knowledgeable, personable, and thorough. Devon helped with everything from my humidifier and diffuser to both of my furnaces, and took the time to answer all of my questions with patience and clarity. He made the whole process smooth and stress-free. I truly hope I can have him as my technician every time—he’s a great guy and a real asset to the company!

We had a great experience with Jansen Heating and Cooling! They were my second call, I wanted to get another opinion after the first company told me our system needed to be replaced. Brett took the time to show me potential issues the landscaping could be causing with the outdoor unit, before he even started his assessment. After the service call, I received a full (data driven) report that explained everything positive & negative about the performance of our system.

I manage a service focused business and I'm typically critical of other service companies. With that being said, I was very impressed with Jansen. Their Dispatcher was extremely friendly when I called in, their Tech was thorough and knowledgeable, and I feel we received more than what we paid for. I even signed up for their subscription maintenance program.

If you're trying to find the "easy button" to address your HVAC issue, I would definitely recommend Jansen Heating and Cooling.

I called Jansen multiple times between May 26th and 27th to try and get a technician in my home to determine why there was water all over my floor from my HVAC unit (furnace).
On my last phone call of the 26th, which was after hours and after I had called other companies trying to find someone available, I was told that I would be called back in the morning to schedule an appointment. I was not and I had to call myself.
On May 28, a technician was sent to my home and he determined my pump had failed. The drainage pump was replaced and the drain was checked to make sure it was clear.
On June 6, I found water all over my floor again. I called and the technician arrived a day later, said the pump was faulty, and I'd have to get a replacement. He did not have a replacement for me in his truck, and he told me that I could wrap a towel around the pump and it would be okay until another technician was sent. I was under the assumption I would be called sometime in the same week to create an appointment to fix this problem (again, for something Jansen installed and determined broken). I was not called back.
On June 15 I called and was told the only availability was June 24. I made the appointment, trying to be patient as there's a pandemic.

Once I noticed mold and water damage, however, my patience went out the window.

Multiple associates at the Jansen front desk were rude to me when I would call, and did not take me or my concerns seriously. The technicians are nice enough, but their pleasantries does not change the fact that I:

- Paid $457.16 for a water pump to be replaced, which was determined broken on installation by the second technician.
- Was never called by their office to set up a follow-up appointment after the second technician informed me he did not have a pump in his truck.
- Now have damaged floor tiles, water damage in my walls, and damaged trim from the water leaking from the pump that Jansen installed.
- And to top it off, the issue was a ripped tube that took ten minutes for a licensed plumber (unaffiliated with the company) to fix.

As of this time, I have not been issued a refund.

Edit 6/23: Still no refund and no attempt to contact me to correct damage that Jansen's technicians caused. But I'm glad the owner has time to comment on five star reviews.

Devon did my tune-up today and was great—super knowledgeable, helpful with different system issues, friendly, and went above and beyond to make sure everything was tuned up. Great technician! I’ll definitely use them again.

I want to thank Jansen for their speedy response to my parents ac repair. I especially want to thank Brayden for his attempt to find the issue. He went the extra mile to try to get the ac working on a really hot day.

We've been Jansen customers for years, and we'll no doubt continue to be Jansen customers for years to come. They've always been quick to respond, the techs always nail down and fix the problem quickly, and they're very reasonable, price-wise.
