For homeowners and property managers who want it done right, we offer a complete lineup of residential and commercial HVAC services across Greenwood and the surrounding Johnson County area. From a quick repair visit to a full system replacement, work performed by qualified HVAC technicians every time, no shortcuts.
When your air conditioner stops cooling, blows warm air, or quits entirely on a July afternoon, we diagnose the problem fast. We service all makes and models, covering condenser and compressor issues, refrigerant leak diagnosis, and airflow problems that leave some rooms cooler than others. If your system is struggling to keep up or cycling on and off, give us a call before a small issue becomes a full breakdown.
A furnace that stops heating in January is not something you wait on. We repair gas furnaces, electric heating systems, and hydronic boilers used for radiant space heating. Whether your furnace is blowing cold air, short-cycling, or simply not turning on, we find the cause and fix it. We keep your home comfortable in every season.
An outdated thermostat can cost you real money in wasted energy. We install programmable and smart thermostats that give you better control over your comfort and your utility bills. Zoning systems are also an option for homes or buildings where different areas need different temperature settings.
Leaky ductwork sends conditioned air into your attic or crawlspace instead of your living areas, and most homeowners never know it is happening. We inspect, repair, and seal ductwork to restore proper airflow and help your system run more efficiently. It is one of the more impactful upgrades you can make without replacing any equipment.
Greenwood summers bring heat and humidity, and that combination can affect the air inside your home as much as the air outside. We install whole-home air filtration systems, air purifiers, and humidity-control equipment to improve what your family breathes every day. One call, and a technician is on the way.
Johnson County sits squarely in Indiana's four-season climate zone: cold winters that push furnaces hard, and hot, humid summers that do the same to air conditioners. Systems here do not get a long break between seasons, and the humidity that builds through summer is a real comfort and air-quality issue, not just a minor inconvenience. These are the services that come up most often for homes and buildings in this area.
Some homes need a full system replacement. Others just need a tune-up. When a repair estimate climbs past what the equipment is worth, or when an aging system keeps failing season after season, replacement is the smarter call. We walk you through the options honestly, size the equipment correctly for your home or building, and handle the full installation. You can expect a thorough removal of the old system, proper installation of the new one, and a full check of airflow and performance before we leave. Straight answers about your furnace, AC, and ductwork, no surprises.
Heat pumps are gaining ground across Indiana as homeowners look for efficient year-round heating and cooling from a single system. A properly sized heat pump handles both seasons without the fuel costs of a gas furnace alone. We install traditional ducted heat pumps as well as mini-split and ductless systems for additions, garages, or spaces that do not have existing ductwork. We stand behind every system we service, and installation is no different.
Indiana summers are humid, and a standard air conditioner can only do so much. When indoor humidity stays high, it affects comfort, air quality, and even your home's structure over time. A whole-home dehumidifier connects directly to your HVAC system and pulls excess moisture out of the air automatically. We size and install the right equipment for your square footage, and we pair it with air filtration where it makes sense. The result is a home that feels cooler, breathes cleaner, and runs more comfortably all summer.
Comfort problems don't wait, and neither do we. Whether your furnace goes out on a January night or your air conditioner quits in the middle of an August heat stretch, we make same-day service available for urgent situations. No heat and no cool are both real emergencies, and we treat them that way.
We answer when you call. We arrive when we say. We leave it running right.
Call (463) 444-9782 when your system is down and you need help today.
Don't let a small problem turn into a no-heat night or a no-cool afternoon. A seasonal tune-up catches the issues that build quietly over months: worn contacts, dirty coils, low refrigerant, restricted airflow. We run a thorough inspection and service in the spring before cooling season starts, and again in the fall before you are depending on your furnace every day. Both visits include cleaning, calibration, and a full check of the components that fail most often. Regular maintenance also keeps your system running efficiently, which matters when equipment is working hard through a full Indiana winter or a humid Greenwood summer. Let us handle the install and the permits.
Greenwood homeowners count on us for everything from a single-room comfort problem to a full system replacement. We work in single-family homes, older homes with aging equipment, and new construction where the system needs to be set up right from the start. Whatever the situation, you get a team that knows the local housing stock and the climate it operates in.
Landlords, property managers, and light commercial building owners have different needs, and we understand that. Tenant comfort depends on fast scheduling and reliable follow-through. We work with rental property owners and apartment managers across Johnson County who need responsive service without the runaround. We take pride in the HVAC work we leave behind, and that applies to every property type we service.
We serve Greenwood and the communities around it, including Bargersville, Whiteland, New Whiteland, Franklin, Trafalgar, Mooresville, and the broader Johnson County area. Most of these areas are a short drive from our base, and we can typically get a technician out quickly when the schedule allows. If you are nearby and need HVAC service, give us a call and we will get you on the schedule.
Gene Ray Heating & Cooling has been serving Greenwood and Johnson County since 1976, which means we have been at this for nearly fifty years. We are locally owned, and when you call, you reach someone who knows this area, knows the equipment that runs in these homes, and can give you a straight answer about what your system needs. We take pride in the HVAC work we leave behind, and that has been true since the beginning. Every job is handled by qualified HVAC technicians who know what they are doing and do it right. One call, and a technician is on the way.
We make same-day service available for urgent no-heat and no-cool situations, including evenings and weekends. Call (463) 444-9782 and describe what is happening, and we will tell you how soon we can get someone out. Emergency calls get priority attention because we know they cannot wait.
A no-heat situation in winter, a no-cool situation during a heat stretch, or a system that has shut down completely and will not restart are all genuine emergencies. Unusual smells, sounds that indicate a mechanical failure, or a system that is running but producing no conditioned air can also warrant an urgent call. When in doubt, call us and describe what you are seeing.
Common signs include the system short-cycling on and off, uneven heat across the home, a noticeable rise in utility bills without a change in usage, or the system running constantly without reaching the set temperature. Strange sounds or smells during operation are also red flags. Any of these symptoms are worth a service call before the system fails completely.
The technician starts by reviewing what you have noticed and then inspects the system from the thermostat to the air handler and the outdoor unit. They check refrigerant levels, airflow, electrical connections, and the condition of key components before identifying the cause. That diagnostic process is what allows us to give you an accurate estimate before any repair begins.
We inspect the evaporator coil, blower motor, air filter, and drain components, and we check for any signs of restricted airflow, ice buildup, or wear on moving parts. Thermostat communication and control wiring are also checked as part of the visit. The goal is to understand how the full system is performing, not just the part that triggered the call.
An air conditioner that runs without cooling is often dealing with low refrigerant, a dirty evaporator coil, a failing compressor, or a restriction in airflow. Some of those issues are straightforward repairs. Others, especially a failing compressor in an older system, can make replacement the more cost-effective option. We diagnose the cause and give you a straight answer about what makes sense.
A frozen evaporator coil is usually caused by restricted airflow, a dirty filter, or low refrigerant. When the coil ices over, the system cannot transfer heat effectively and cooling drops off sharply. If you notice ice on the indoor unit or refrigerant lines, turn the system off and call us. Running a frozen system can damage the compressor.
A heat pump replaces a separate furnace and air conditioner with a single system that handles both heating and cooling. During installation, we remove the existing equipment, size and install the new heat pump, connect it to your existing ductwork where applicable, and test the full system before we leave. For homes without ductwork, we install ductless mini-split systems that work the same way.
A full replacement starts with a thorough assessment of your home or building to make sure the new equipment is sized correctly. We remove the old system, install the new one, check all duct connections and airflow, and test heating and cooling operation before we consider the job complete. Permits are handled as part of the process, and we walk you through what was done before we leave.
Leaky ducts send conditioned air into unconditioned spaces like attics and crawlspaces, which means your system works harder and runs longer to reach the set temperature. Undersized ducts restrict airflow and create pressure imbalances that cause uneven temperatures and added wear on the equipment. Sealing or replacing problem ductwork can make a significant difference in both comfort and efficiency.
Older homes often have uneven temperatures from room to room, drafts near windows and exterior walls, and HVAC equipment that was never sized correctly for the actual square footage. Aging ductwork with leaks and an outdated thermostat that does not communicate well with the system make those problems worse. We assess the full setup and recommend the right combination of repairs, upgrades, or replacement.

How do I know if my furnace or AC needs to be replaced rather than repaired?
Age and repair history are the two biggest factors. If a system is more than 15 years old and has needed multiple repairs in recent seasons, replacement often costs less over time than continuing to fix an aging unit. We look at the condition of the equipment, the cost of the repair, and what a replacement would realistically cost, then give you a straight answer so you can make the call with full information.
What does a seasonal tune-up actually cover?
A tune-up is a full inspection of the system, not just a filter swap. We check refrigerant levels and look for leaks, measure airflow, clean the evaporator and condenser coils, test and calibrate the thermostat, inspect electrical connections and controls, and assess any components that are showing wear. The goal is to catch small problems before they become emergency calls and to make sure the system is running at the efficiency it was designed for.
Why is one room always hotter or colder than the rest of the house?
Uneven temperatures usually point to an airflow problem. The most common causes are leaky or disconnected ductwork, an undersized supply register, a dirty coil or filter reducing overall airflow, or a zoning issue in a larger home. We can measure airflow at the registers and trace the problem back to its source rather than guessing.
Transparent Pricing on Every Job
Before any repair or replacement begins, we give you a clear estimate covering parts and labor. You know the number before we start, not after.
How often should I schedule HVAC maintenance?
Once a year at minimum, and twice a year is better if you are running both a heating and a cooling system. A spring visit prepares the AC before summer demand peaks, and a fall visit gets the furnace or heat pump ready before the first cold snap. Staying on that schedule keeps the equipment efficient and gives us a chance to catch issues before they turn into no-heat or no-cool calls.
What are signs of a refrigerant or airflow problem?
With refrigerant, the most common signs are an AC that runs constantly but never quite cools the space, ice forming on the refrigerant lines or evaporator coil, or a hissing sound near the indoor or outdoor unit. Airflow problems show up as weak output at the registers, rooms that feel stuffy, or a system that short-cycles because it cannot move enough air. Both situations call for a technician to diagnose the root cause before any repair is attempted.
Can I do anything myself before calling a technician?
A few checks are reasonable. Make sure the thermostat is set correctly and the system switch is in the right position. Check whether a tripped breaker has cut power to the unit. Replace the filter if it has not been changed recently, since a clogged filter can cause a system to shut down on a safety limit. Beyond those steps, the equipment involves refrigerant, electrical components, and combustion systems that are best left to qualified HVAC technicians.
Same-Day and Emergency Availability
When your heating or cooling goes down and cannot wait, we make same-day service available, including evenings and weekends throughout the Greenwood area.
How does pricing work, and will I know the cost before work starts?
Yes. The normal first step is a diagnostic or service-call inspection so we know exactly what the system needs. From there, we give you a clear estimate covering parts and labor before any repair or replacement begins. If the technician finds additional problems during the inspection, we explain what was found and what it will cost to address before doing anything extra. Nothing gets added to the scope without your approval.
Is same-day service actually available, or is that just a marketing claim?
We make same-day service available for urgent no-heat and no-cool situations, including evenings and weekends. Calling early in the day gives us the best chance of reaching you the same day. During peak seasons, same-day slots fill quickly, so the sooner you call, the better. We will tell you exactly what we can do for your situation when you reach us.
Work Performed by Qualified HVAC Technicians
Every job, from a seasonal tune-up to a full system replacement, is handled by qualified HVAC technicians who know the equipment and care about the outcome.
What does a heat pump installation involve, and is it a good fit for Indiana winters?
Installation starts with a load calculation to size the equipment correctly for the home. We then handle the full installation, whether it is a ducted system tied into existing ductwork or a ductless mini-split for a specific area. A well-sized heat pump handles a typical Greenwood winter efficiently and covers summer cooling in the same unit. We test the system in both heating and cooling modes before we leave.
What causes a system to short-cycle, and should I be concerned?
Short-cycling is when the system turns on and off more frequently than normal without completing a full heating or cooling cycle. It puts extra wear on the compressor and blower motor and usually signals an underlying problem: a clogged filter, a refrigerant issue, a failing component, or an oversized system that heats or cools the space too quickly. It is worth having a technician look at it before the cycling damages more expensive parts.
How long does a full system replacement take?
Most residential system replacements are completed in a single day. The timeline depends on the equipment involved, whether any ductwork modifications are needed, and the accessibility of the installation area. We will give you a realistic time estimate when we review the job, and we keep you posted throughout the process so you know where things stand.
Every home and every system is a little different, so call us at (463) 444-9782 and we will walk you through exactly what your situation calls for.
