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.

Chad does a great job. He's very thorough and explains everything well. We recently moved and Chad worked on the system at our previous residence. Thus, it was comforting to have him again at our new home. We've always had the HVAC annual maintenance contract. It's a great value and JonLe calls us to schedule. So we don't have to remember. Great to work with. Thank you!!

We’ve always been happy with Jonle. Our service rep Dan, is very knowledgeable and we always ask for him for our annual maintenance.
Had JonLe out for a furnace service and started a maintenance plan with them. Very professional and informative and focused on just what I needed and did not try to upsell.

We have been using JonLe for years. Always professional and courteous. Very trustworthy. Thank you
I have been a Jonle regular for a lot of years. I actually have never been disappointed by any of the techs Jonle have sent. They are polite trustworthy types. When Cory was finished with the service, he asked there was anything else he could do for me before he left. I asked about the basement lights being off. He let a light on that was on when he went down. He ran back downstairs for me and turned it off. Not a service requirement. But it is something a nice guy does for an getting older lady.
JonLe is a professional organization. Technicians are knowledgeable and professional. I have used JohLe for over 25 years.
Very professional and knowledgeable technician. I was very impressed with the service.
I was impressed but this company. They got here quick sent a text with technical's picture saying he was on the way. Since my husband couldn't be here it made me feel safe just knowing who was coming. Matt was very professional and nice took time to explain the issue with our boiler system along with pictures showing the damage. Waiting on estimates for part replacement versus replacement of boiler. Great job that's for going above all rest. The picture text A+
They called ahead to see if they could come earlier, not an issue. Cory was respectful and worked quietly and finished his work with no issues. Highly recommend them.
Received great service in one day 22 degrees outside definitely use this team again. Thanks guys
