Hvac Service in Florence, Ky, Dependable Repairs And Year-round Home Comfort
Florence is one of Boone County’s largest cities, sitting about 12 miles south of downtown Cincinnati along the I-71 and I-75 corridor. With a population of more than 33,000 and a mix of established neighborhoods, growing subdivisions, and a strong commercial corridor along Turfway Road and US-42, Florence has become one of Northern Kentucky’s most active communities. Residents here take pride in their homes, their schools, and the tight community feel that sets Boone County apart from other Cincinnati suburbs.
It is also a city where your HVAC system earns its keep every single month. Northern Kentucky summers run hot and humid, with heat index readings that regularly push past 100 degrees and humidity levels that make a working air conditioner non-negotiable. Winters in Florence bring weeks of below-freezing temperatures, and the older ranch homes and mid-century houses throughout the city put real demand on furnaces, boilers, and heat pumps. Many Florence homes were built between the 1960s and 1990s, which means aging ductwork, older equipment, and systems that need consistent, qualified attention to stay reliable.
JonLe Heating & Cooling is a family-owned HVAC company that has served the greater Cincinnati and Northern Kentucky area for over 65 years. Our NATE-certified technicians handle everything from emergency furnace repairs to full AC installations with upfront pricing and on-time arrivals.

Hiring the wrong HVAC contractor can cost you more than money. A poorly installed furnace can leak carbon monoxide, which is exactly why we include carbon monoxide alarm installation as part of our safety services. A mismatched AC unit will short-cycle, wear out faster, and drive up utility bills month after month.
JonLe Heating & Cooling is a Carrier Factory Authorized Dealer and Carrier Dealer Hall of Fame member. We hold Ohio HVAC License HV51208 and Kentucky License HM637357. Every technician on our team is NATE-certified, background-checked, and arrives with shoe covers to protect your floors. We have been doing this since 1959, when Jon Leisgang started installing boilers on Cincinnati’s west side. Three generations later, we still run on the same values: show up when we say we will, do the job right, and treat every home like our own.

Common HVAC problems we fix in Florence homes
Florence has a wide mix of housing, from mid-century ranch homes and 1970s split-levels near the older city core to newer subdivisions built in the 1990s and 2000s further out. That housing mix creates specific HVAC challenges. Here are the issues our technicians see most often in this area:
- Uneven temperatures between rooms: Poor ductwork design, leaky ducts, or an oversized system that short-cycles. A furnace maintenance or AC maintenance visit often uncovers the root cause.
- Furnace blowing cold air: A failing ignitor, dirty flame sensor, or malfunctioning limit switch. Common in older furnaces that have not had annual maintenance.
- AC running but not cooling: Low refrigerant, a dirty condenser coil, or a worn-out compressor struggling against Northern Kentucky’s summer humidity.
- High energy bills with no change in usage: Aging equipment, clogged filters, or duct leaks that force your system to work harder. Enrolling in our Energy Savings Plan helps catch these issues before they show up on your utility statement.
- Frequent cycling on and off: An oversized unit, thermostat problems, or restricted airflow. Smart thermostat installation can resolve thermostat-driven short-cycling in many Florence homes.
- Strange noises from the furnace or AC: Banging, squealing, or rattling often points to loose parts, a failing blower motor, or compressor trouble that worsens without attention.
- Dry indoor air in winter: Florence winters pull moisture from your home fast. A whole-house humidifier keeps indoor humidity within the EPA-recommended 30% to 60% range.
If you notice any of these signs, call (513) 662-2282 to schedule a diagnostic visit before the problem gets worse.

Frequently Asked Questions About Hvac Service in Florence, KY
Most standard 1-inch filters should be replaced every 30 to 90 days, depending on factors like pets, allergies, and how often your system runs. Thicker media filters can last 6 to 12 months. A clogged filter restricts airflow, forces your system to work harder, and raises energy costs over time. Ask about our Energy Savings Plan for scheduled maintenance that includes filter checks every visit.
A well-maintained furnace typically lasts 15 to 20 years. Central air conditioners last 15 to 20 years with proper upkeep. Heat pumps generally run 10 to 15 years. Regular furnace maintenance and AC maintenance extend equipment life and help you avoid sudden breakdowns at the worst possible times.
Check your thermostat settings and confirm it is set to "heat." Make sure the circuit breaker has not tripped, and replace the air filter if it looks dirty. If the furnace still will not start, call our team for furnace repair in Florence. Do not attempt to open the unit yourself. If you smell gas, contact your gas utility first, then call (513) 662-2282.
Start with regular filter changes and annual HVAC maintenance. For deeper improvements, consider a whole-house humidifier to manage winter dryness, UV germicidal lights to reduce airborne bacteria and mold inside your ductwork, or a ventilator to bring fresh outdoor air in while controlling moisture. A smart thermostat installation can also regulate humidity and temperature automatically for better year-round comfort in your Florence home.
Watch for frequent repairs, rising energy bills, uneven heating or cooling, and excessive noise. If your system is over 15 years old and needs a repair costing more than half the price of a new unit, furnace replacement or AC replacement usually makes more financial sense. Contact our team for a free second opinion.
Yes. Whole-house air purification systems, UV germicidal lights, and media filters can significantly reduce dust, allergens, mold spores, and bacteria circulating through your ductwork. For commercial spaces, commercial air purification systems offer higher-capacity solutions. Our technicians can assess your indoor air and recommend the right option for your Florence home or business.
Every home and system is different, so pricing depends on the type of service, the equipment you have, and the scope of work involved. Contact our team at (513) 662-2282 for a detailed quote with no obligation.

We have used Jonle for over 20 years and would not use anyone else. Always knowledgeable, professional and quick to respond to appointment needs!
Jason Goad was an incredibly help to us. He was knowledgeable and thorough. Our air went out Sunday and he was here Monday morning. So we didn’t suffer long! I can’t recommend him and Jonle enough. 5 stars!
I was very pleased with the how quickly a technician arrived. Steve was very friendly, diagnosed the problem, and explained the issue. He was able to put on a new part and was good at explaining in laymen terms what went wrong . I was very thankful for the quick and we efficient service and intend to make another appointment for maintenance.
Technician was prompt, wore shoe protection, and performed the checkup quickly. Not much of a conversationalist however.
Prompt, same day response. Service technician was polite and efficient and finished in an hour
My technician today, Will, performed an exceptional job, checking my HVAC unit at my home. He was professional, polite, friendly, and efficient. He checked all the systems inside and outside, cleaned everything, made a recommendation for a future upgrade and double checked the thermostat before he left. Will wore booties all the time to keep my home clean.
Cory saved the day!! My AC wasn’t cooling and my house was up to 86 degrees. I booked an appointment online (the best thing ever!) in the middle of the night and they were out the next afternoon. Communication on the tech’s arrival was great, I got a call and text when he was on his way. Cory was friendly and explained what our issue was and took care of it quickly! He also explained their maintenance/value plans to keep my system in great shape. So grateful for the quick and professional response. Thank you Jonle team 😊
Jonle Heating & cooling, has been coming to my house for quite awhile. The person that does the work is Chad, & he throughly looks at & tests everything on the furnace unit & the condensing unit outside every 6 mos. So glad my father had them before me.
JonLe/Tri-County Heating & Cooling installed our HVAC systems when we built our house 27 years ago. They have serviced our units ever since. And though we replaced both A/C compressors a few years ago, both furnaces are still doing just fine. These guys have outstanding customer service. Every technician who has ever been to our house has been on-time, friendly, and professional. I cannot imagine having better service. They are the best. Thank you!
Todd showed up at the house promptly very professional very informative. Couldn’t have asked for a better experience thank you, Todd.
Edit: They contacted me a couple days later (and a couple days after the initial review) and did ultimately honor their original quote, so have updated to 4 stars. Dino is a great tech to work with. Original review: Tech was friendly, professional, and seemed knowledgeable. Also used shoe covers indoors, which was appreciated. Low rating is because I was told over the phone (I believe by Barbara, though I was told this by 2 different people by phone and I didn't write down the names) that the price I was quoted was for both A/C and furnace maintenance together in one trip. I was instead told when the tech arrived that price was only for A/C and it would be double that price for both. Miscommunications can happen, though twice on the same day made this feel like a bait-and-switch. Had I known, I would have gone with the other company I got a quote from that offered to do both for a little more than I was just charged for one (since I didn't want to deal with scheduling another appointment). Personally I won't use them for any additional services or recommend them to friends at minimum unless a written estimate is given.
The technician was very professional. On the cost, I am on the gold plan so the cost is nil
We called JonLe heating and cooling in the morning with air conditioning issues. Steve arrived by 1:30 for service. Our unit was fixed within an hour at a very fair price.
Explained everything, very professional, and was on time. I definitely recommend!
I have used Jonle heating & cooling for many years. The installed my new furnace and performs maintenance twice a year. They are reliable, curtious and always do a great job. I can rest easy knowing my furnace is in great condition.
I have used Jonle for several years. They give notice of being on the way, they are always on time, very polite and professional. They do a thorough inspection. I highly recommend them for installation and repair.
Jonle has kept us up and running for years using the Silver Service maintenance for air and heat.
Frank B was great. Very thorough in his review and presentation of our system and options to consider for our final decision.
Professional, priced more than fair, great communication. Highly recommended
The Jonle guys just completed the 2x / year service and were great to work with. From putting booties on before they entered the house, to their quick, efficient and effective work, to their knowledge- all was great. I recommend them all the time!
Highly recommend JonLe Heating & Cooling! Our AC froze up a few weeks back. The "other guys" who didn't catch our AC leak during the spring tune-up appointment came out quoting crazy high costs to recharge, crazy high repair estimates, and provided us 4 new AC unit options with little information or context. Then the pressure tactics started the next day: only one unit left in stock, one appointment tomorrow and next available a week out, etc. After a reasonably priced recharge from a friend of a friend, I was able to extend the life of the AC in order to shop around. JonLe Heating & Cooling provided a free second opinion. Frank came out for a visit, assessed the current state, and worked with us to understand our AC concerns in order to quote the correct system for needs. We did not have to debate whether a seer X rated system was worth hundreds or thousands more than a seer Y rated system. Frank recommended and quoted a single system to us, and walked us through the specs and features and throroughly explained the pros/cons and why this system fit our needs. At that point, I was happy to leave the "choose your own adventure" pricing of the other guys behind. Admittedly, I was bracing myself for sticker shock, but feeling confident about spending money on the right system for us. I was pleasantly surprised that the system was not only better spec'd than the other guys "top tier" option, but was also THOUSANDS of dollars cheaper. Win-win! Install went smoothly. Techs were super friendly. Frank even stopped by to check in on the progress midday. And to top it all off, JonLe did not charge a processing fee for using a credit card. All around amazing experience with JonLe Heating & Cooling. Highly recommend!
Quick response! Jason was an excellent service tech. He was informative and efficient. Thank you so much.
Jonle has been servicing my HVAC for years. Also installed my current systems. Always dependable with positive results. Their personnel are always courteous and helpful
JonLe does a fantastic job. Their technicians are very knowledgeable, show up on time and do a thorough review of our HVA system.
Chad is very knowledgeable and was able to identify the AC problem quickly. Highly recommended!
Hello! I'm a little late posting my review because life has been busy. Anyways. I came home from work to a VERY HOT house and immediately knew something was wrong. I contacted JonLe the next morning and they were very helpful, kind and were able to squeeze me in that same morning. Todd S. called to notify me that he was on his way and arrived a short time later. After looking over my unit and listening to my description of what was going on, he quickly diagnosed the issue and told me what part needed to be replaced, quoted me an affordable and reasonable price to repair and got to work. Todd saved the day for me. He stayed a few extra minutes longer to ensure my unit was working properly and that I was able to notice the cold air flowing out. He is absolutely amazing and I am eternally grateful for his assistance and hard work. Thank you, Todd and JonLe!!! They definitely get all five stars from me!
Service arrived in the expected window of time and Cory took his time evaluating since our issue was a bit of a mystery. Cory explained everything in a clear manner. We were given options and with his professional experience came up with a plan with no pressure.
JonLe heating and air conditioning personnel have always been courteous, well qualified and always take care of furnace and air conditioning needs. Steve has been service person whom I always ask for. So he has been servicing my utilities for many years. He is excellent. I always know and feel confident that all will be well after he has done yearly maintenance. Staff whom I speak with to schedule appointments are always very helpful and cordial. They work with my schedule which can be dicey.
Great service. My technician was knowledge and freely shared that knowledge with me so I understood what happened with my unit.
Called on a Monday morning they were here in 30 minutes. I can tell you I have a hot water boiler they fixed street side auto fill valve and a backflow preventer. 2 of the nicest guys, explained in detail very friendly honest open. Office staff was great as well... They even came next morning to readjust something at no charge.. very cool. They are my go to.
Mark was thorough and professional. Did take over a month for appointment
My technician today was Mark Johnston. He was top notch. He is thorough , efficient and always friendly and completes his task in a timely manner. I have been a customer of jonle for years Excellent company.
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.
Have trusted them with our HVAC maintenance & repairs for years. They are thorough, respectful and honest. Will Ross did a great job servicing our AC.
This company always does a good job no matter who they send. Jason did a great job today and explained everything he did etc. All good!
I have been a customer of Jonle for many years and have recommended their services to many neighbors and friends. Their technicians are friendly and knowledgeable. I wouldn't use any other company!
Great service representative. Explained what he was doing, politely and wore shoe covers.
I've been using JonLe for my HVAC services for years and their technicians have always been professional, thorough, and honest. Today, Mark came out to do my annual AC maintenance. He's been here before, and I'm always appreciative of how he goes though everything he inspected and tuned up. He's very knowledgable and offers great advice to keep my system in tip top shape. I would highly recommend JonLe to anyone who needs HVAC service.
I had to have the HVAC compressor replaced. Matt, was the Service Repair man who installed my new compressor. He did an excellent job and had my AC up and running in about 4 hours! I was so thankful! I have used JonLe for over 30 years. They were very accommodating and was able to get my AC up and going on a 90° day! I have always been very pleased with their workmanship and their staff. I was fortunate enough to have the same service man, Dan, for my tune-ups for over a decade. Thank you!
