Hvac Service in Ft. Thomas, KY, Dependable Repairs And Year-round Home Comfort
Ft. Thomas is a well-established residential city in Campbell County, Kentucky, sitting just across the Ohio River from Cincinnati. Known for its tree-lined streets, historic homes, and the landmark Tower Park with its commanding views of the river valley, Ft. Thomas has a character that is equal parts quiet suburb and close-knit community. Housing stock ranges from early 20th-century Craftsman bungalows and Tudor-style homes to mid-century ranches and newer construction — a mix that creates a wide range of heating and cooling needs under one ZIP code.
It is also a community where your HVAC system earns its keep every single month. Campbell County summers bring consistent heat and humidity that regularly pushes into the high 80s, making a well-functioning air conditioner something you rely on rather than simply appreciate. Winters in Northern Kentucky drop well below freezing for weeks at a time, pulling moisture from indoor air and placing heavy demand on furnaces, boilers, and heat pumps. Older homes throughout Ft. Thomas need consistent, qualified attention to keep performing safely and cost-effectively.
JonLe Heating & Cooling is a family-owned HVAC company that has served the greater Cincinnati 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. A mismatched AC unit will short-cycle, wear out faster, and drive up your 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 Ft. Thomas homes
Ft. Thomas has a significant number of older homes, including early 20th-century Craftsman bungalows, Tudor-style properties, and mid-century construction. That housing stock creates specific HVAC challenges. Here are the issues our technicians see most often in this community:
- Uneven temperatures between rooms: Poor ductwork design, leaky ducts, or an oversized system that short-cycles before conditioned air reaches every room. A furnace repair or AC repair visit can identify the root cause.
- Furnace blowing cold air: A failing ignitor, dirty flame sensor, or malfunctioning limit switch. Our furnace repair technicians diagnose and fix these issues same day in most cases.
- AC running but not cooling: Low refrigerant, a dirty condenser coil, or a worn-out compressor struggling against Northern Kentucky’s summer humidity. Schedule an AC repair before the problem gets worse.
- High energy bills with no change in usage: Aging equipment, clogged filters, or duct leaks that force your system to work harder for the same output. Furnace maintenance or AC maintenance can often resolve this.
- Frequent cycling on and off: An oversized unit, thermostat problems, or restricted airflow from old ductwork. A smart thermostat installation can also help regulate cycling behavior.
- Radiator and boiler issues: Older Ft. Thomas homes with steam or hot water heating often develop leaks or pressure problems. Our boiler repair service covers all common radiator system faults.
- Dry indoor air in winter: Northern Kentucky winters pull moisture from your home quickly. 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 Ft. Thomas, 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.
A well-maintained furnace typically lasts 15 to 20 years. Central air conditioners and heat pumps run 10 to 15 years. Regular furnace maintenance and AC maintenance extend equipment life and help you avoid sudden breakdowns.
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, contact us for furnace repair — do not attempt to open the unit yourself. If you smell gas, contact your gas utility first.
Start with regular filter changes and annual furnace maintenance. For deeper improvements, consider a whole-house humidifier to manage winter dryness, or UV germicidal lights to reduce airborne bacteria and mold inside your ductwork. A smart thermostat installation can also help regulate humidity and temperature for better year-round comfort.
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 purifiers, UV germicidal lights, and media filters can reduce dust, allergens, mold spores, and bacteria circulating through your ductwork. For commercial spaces, commercial air purification systems provide building-wide coverage. The right solution depends on your home's specific air quality concerns — our technicians can assess your setup and recommend the best option.
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. You will receive clear, upfront pricing before any work begins.

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.

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!

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.

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!

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!

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.

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!
