Corna Heating and Air has been the go-to HVAC contractor in Ocala for 25 years. Since 2001, we have handled heating, cooling, installation, repair, and maintenance for homeowners, landlords, property managers, and commercial clients across Marion County. We've serviced and replaced systems all over these neighborhoods, and the work we did on day one is the same work we stand behind today. Residential HVAC. Commercial HVAC. One number for both.
We are a local HVAC company homeowners rely on, and that reputation did not happen by accident. It came from showing up on time, explaining the problem clearly, and doing the job right. Give us a call and we'll get the comfort back.
Noticing uneven temperatures or a spike in energy bills? Those are the calls we get every week, and they almost always point to something we can diagnose and fix. We cover the full range of heating and cooling work: AC repair and service, heating repair, heat pump service, full system installation and replacement, ductwork repair and sealing, thermostat and smart-control installation, indoor air quality, seasonal maintenance, and emergency service when your system goes down at the worst possible time.
We work on single-family homes, rental properties, small businesses, office buildings, retail spaces, and restaurants. Whatever the property type, the job is the same: find the problem, explain it in plain terms, and fix it correctly. That means honest recommendations on repair versus replacement, never an upsell. We are not here to sell you a new system if your current one can be repaired at a reasonable cost. We will tell you which option makes more sense and let you decide. Leave the heating and cooling to us.
Dealing with an AC that can't cool? In Ocala's heat and humidity, a system that is struggling or has stopped working is not a minor inconvenience. It is a comfort and safety issue, especially during the long Florida summer. We handle the full range of AC work: AC not cooling, AC blowing warm air, AC stopped working entirely, central air repair, evaporator coil cleaning and repair, condenser and compressor service, refrigerant leak diagnosis, and AC unit replacement when repair is no longer the right call.
We offer same-day and emergency AC repair for situations that can't wait. Whether your system quit overnight or started blowing warm air in the middle of the afternoon, we provide prompt response, even for last-minute comfort calls. New AC installation and central air replacement are also part of what we do, and we will walk you through the options before any work begins. Your system is in good hands with us.
The hardest part of an HVAC problem is knowing when to call, and with heat pumps, the signs can be subtle at first. Heat pumps are the workhorse of comfort in central Florida. They handle both heating and cooling from a single system, which makes them the right fit for this climate and the most common equipment we service in Marion County.
We repair, service, and replace heat pumps of all makes and models. If your heat pump is not heating, not cooling, short-cycling, or making sounds it should not be making, our technicians will run a full diagnostic and tell you exactly what is going on. We also install new heat pump systems and ductless mini-split systems for homes or spaces where traditional ductwork is not practical. Zoning and comfort-control options are available for customers who want more precise temperature management room by room. Work is performed by qualified HVAC technicians who know this equipment inside and out. We're ready to get your heating and cooling running again.
Comfort problems don't wait, and neither do we, which is why we look at the whole system, not just the unit. Leaking or damaged ductwork is one of the most common reasons a system works harder than it should and still falls short. We handle duct sealing, ductwork repair, and full ductwork replacement when needed. In Florida's heat, leaky ducts drive up energy bills fast and put unnecessary strain on the equipment.
Thermostat issues are another frequent culprit. If your thermostat is not responding, reading temperatures inaccurately, or simply needs an upgrade, we install programmable and smart thermostats including Nest and Ecobee models that give you better control and can help reduce energy use over time.
Indoor air quality is a real concern in a climate like Ocala's, where homes stay closed up and humidity levels run high for much of the year. We install whole-home air filtration systems, UV air purifiers, air scrubbers, and whole-home dehumidifiers to keep moisture and airborne contaminants under control. A comfortable home is not just about temperature. We're ready to get your heating and cooling running again.
What sets our technicians apart is straightforward: they have done this work for years, they take it seriously, and they treat your home or building with respect. Every technician we send out has hands-on experience across the full range of HVAC work, from routine maintenance to full system replacements. They carry the tools to diagnose accurately, explain findings clearly, and complete the job without cutting corners.
We have been building this team since 2001, and the standard has stayed the same throughout. When a technician shows up at your door, they are there to solve a problem, not to run up a ticket. That consistency is what keeps customers calling us back year after year.
Seasonal maintenance is one of the most straightforward ways to avoid an expensive repair call down the road. A proper tune-up covers the filter, coil cleaning, refrigerant level check, airflow test, and blower and motor inspection. We catch small problems before they become big ones and make sure the system is running at its best heading into the season ahead.
When a system has reached the end of its useful life, we give you a straight answer on replacement. We do not push new equipment on customers who do not need it, but when repair costs are stacking up or a system is simply too old to run efficiently, we will tell you clearly. Full HVAC system replacement includes removing the old equipment, installing the new system correctly, and testing everything before we leave. Honest recommendations on repair versus replacement, never an upsell. Work is performed by qualified HVAC technicians on every job, whether it is a tune-up or a full system swap. We're ready to get your heating and cooling running again.
Comfort problems don't wait, and neither do we. If your system goes down in the middle of the night, over a holiday weekend, or on the hottest afternoon of the year, we are available. No heat, no cooling, system completely unresponsive: these are the calls we take around the clock for both residential and commercial customers.
Same-day service is available for urgent situations, and we make prompt response a priority, even for last-minute comfort calls. We do not leave you waiting when the problem cannot wait. We find it. We fix it. We test the airflow.
Pricing surprises after the job is done are something we simply do not do. Before any work begins, we go over the scope of the job and the cost with you. You know what you are paying before a technician picks up a tool. Pricing varies depending on the job, the equipment involved, and the parts required, but the estimate you receive reflects the actual cost of the work.
Scheduling is straightforward. Call us for a quote or to set up a service call, and we will get you on the calendar. For urgent situations, we work to get a technician out the same day. We keep the process simple because that is what customers deserve.

Yes, leaving the work area clean is part of the job for us. We remove old parts, packaging, and any debris from the work area before we leave. The space should look the same or better than when we arrived.
We stock our service vehicles with the tools and common parts needed to handle most repairs and service calls without a return trip.

| Service Type | What the Service Includes | Common Needs | Things to Know |
|---|---|---|---|
| Thermostat and Smart-Control Installation |
| homeowners looking for better comfort control and lower monthly energy costs | An outdated or miscalibrated thermostat can cost money every month; a smart upgrade pays for itself quickly during a long Florida cooling season |
| Indoor Air Quality and Air Filtration |
| households with allergy sufferers, respiratory sensitivities, or persistent odor and air quality concerns | Florida's year-round pollen and humidity create real indoor air quality challenges; filtration systems work alongside existing HVAC equipment and do not require a separate unit |
| Ductwork Repair and Sealing |
| homes with uneven temperatures, high energy bills, or visible duct damage | Leaky ducts sending conditioned air into the attic are one of the most common hidden causes of comfort problems and high utility costs in Florida homes |
| Heat Pump Installation |
| homeowners replacing older equipment or adding comfort to a space without existing ductwork | Heat pumps handle both heating and cooling from one unit, which makes them a practical and efficient choice for Florida's long cooling season and mild winters |
| Seasonal Maintenance and Tune-Ups |
| any homeowner who wants to avoid emergency calls and keep energy bills in check | In a climate where the cooling system runs nearly year-round, a tune-up before peak summer is the most cost-effective HVAC service there is |
| High-Efficiency Central AC Replacement |
| homeowners with aging central AC systems driving up summer electric bills | Modern high-efficiency units carry significantly better SEER ratings than equipment installed a decade ago; the savings show up on every monthly bill through a long Florida cooling season |
| Full System Installation and ReplacementMost Popular |
| homeowners replacing aging equipment or upgrading to a more efficient system | Systems more than 12 to 15 years old or running on discontinued R-22 refrigerant are strong replacement candidates; we give honest repair-versus-replace guidance before recommending anything |
| Whole-Home Dehumidification and Humidity Control |
| Ocala homes that feel sticky or uncomfortable even when the AC is running correctly | A dehumidifier pulls moisture out of the air continuously, not just when the AC cycles on; it addresses the humidity problem the AC alone was never designed to solve |
| Heat Pump Repair and Service |
| homes running a heat pump for both heating and cooling | Heat pumps are the most common system type in this climate; a reversing-valve problem can cause it to lose one mode while the other still works |
| Heating and Furnace Repair |
| households that lose heat during an Ocala cold snap | Heating calls here are seasonal but urgent when they happen; we keep availability open for those moments even outside peak season |
| AC Repair and Service |
| homeowners and landlords with an AC that has stopped cooling or is underperforming | Florida's long cooling season puts extra hours on equipment; catching problems early keeps repair costs lower than waiting until the system fails completely |
| Emergency HVAC Service |
| anyone facing a system failure during a Florida heat wave or an unexpected cold stretch | We keep same-day availability for urgent calls; calling early in the day gives us the best chance of getting a technician to you before conditions peak |
How do I know if my AC needs a repair or a full replacement?
Age and repair history are the two clearest indicators. If a system is more than 12 to 15 years old, has needed repeated repairs in the past couple of seasons, or is still running on R-22 refrigerant that is no longer manufactured, replacement is usually the smarter financial decision. We walk through the honest math with you before recommending anything, so you can decide what actually makes sense for your situation.
Why is one room in my home hotter or colder than the rest?
Uneven temperatures usually point to one of a few things: leaky or undersized ductwork, a blower that is not moving enough air, a refrigerant charge that is off, or a zoning issue. In older Florida homes, duct leakage into the attic is one of the most common causes. We inspect the full system to find the actual source rather than guessing at it.
How often should I schedule a maintenance tune-up?
Once a year is the standard recommendation for most systems, but in a climate like Ocala's where the cooling system runs nearly year-round, scheduling a tune-up before peak summer gives you the best protection against emergency calls during the hottest months. If you have a heat pump handling both heating and cooling, keeping it on an annual schedule is especially worthwhile.
Transparent Upfront Pricing
We give you a clear number before any work begins and do not start until you have approved the scope. No surprises on the invoice is something we take seriously on every job.
What does a seasonal tune-up actually include?
A tune-up covers the essentials that keep a system running efficiently and help catch problems early. That means a filter check and replacement, coil cleaning, refrigerant level check, airflow test, thermostat calibration, and an inspection of electrical connections on the unit. The goal is to find small issues before they become expensive failures.
Why does my system keep short-cycling, turning on and off repeatedly?
Short-cycling is usually a sign that something is forcing the system to shut down before completing a full cooling or heating cycle. Common causes include a dirty or clogged filter restricting airflow, a refrigerant charge that is too high or too low, an oversized system that cools the space too fast, or a failing component like a capacitor. It puts extra wear on the equipment and should be diagnosed promptly.
Can you get a technician out the same day?
Yes, we offer same-day availability for urgent heating and cooling calls, including no-cool situations during Florida's hot months. Calling early in the day gives us the best chance of getting a technician to you before conditions peak. Prompt response, even for last-minute comfort calls, is part of how we operate.
Work Performed by Qualified HVAC Technicians
Every repair, installation, and tune-up is handled by qualified HVAC technicians who know this equipment and this climate. All work is done to code.
How does your estimate process work?
A qualified HVAC technician arrives, inspects the equipment, and explains what they found before any work begins. Once we have a clear diagnosis, we give you a firm number and explain the scope. We do not start work until you have approved it. If repair and replacement are both reasonable options, we tell you the honest difference so you can make the call that fits your budget.
Why is my energy bill higher than it used to be even though the system seems to be running?
Rising energy costs with a system that appears to be functioning are often a sign of reduced efficiency. Dirty coils, a low refrigerant charge, leaky ductwork, or a system that is simply aging past its efficient years can all cause it to run longer and work harder to reach the same temperatures. A tune-up or diagnostic visit usually identifies the cause quickly.
Same-Day and Emergency Availability
When your system goes down during a Florida heat wave or an unexpected cold snap, we dispatch for urgent calls and keep same-day availability for situations that cannot wait.
What causes strange noises from my HVAC unit?
Banging or clanking usually points to a loose or broken component inside the air handler or blower. Grinding can indicate a failing motor bearing. Hissing sometimes means a refrigerant leak. Clicking at startup and shutdown is normal, but clicking that continues while the system runs often points to a relay or control issue. Any noise that is new or getting louder is worth having diagnosed before it turns into a larger failure.
Do I need to be home when the technician comes?
Someone over 18 should be present for the appointment. The technician needs access to the indoor air handler, the outdoor unit, and ideally the thermostat. If pets are in the home, securing them before the technician arrives helps the job move faster. Beyond that, there is nothing special you need to prepare.
Is a whole-home dehumidifier worth it if my AC is already working correctly?
In Ocala's climate, yes, for many households. An air conditioner removes some moisture as a byproduct of cooling, but it only runs when it is actively cooling the space. A whole-home dehumidifier pulls moisture out of the air continuously and can be set to a target humidity level independent of the thermostat. If your home feels sticky even when the temperature is comfortable, or if you have had mold or mildew issues in the past, a dehumidifier addresses the problem the AC was never designed to solve on its own.
Every home and every system is a little different. Call (352) 619-9879 and we will give you a straight answer on what your heating or cooling situation actually needs.
