Some homes need a full system replacement. Others just need a tune-up. Either way, we have the experience and the tools to get the job done correctly the first time.
We cover the full range of residential and commercial heating and cooling work:
All of that work is performed by qualified HVAC technicians who know the equipment and know how to leave a job right. We keep your home comfortable in every season.
Comfort problems don't wait, and neither do we. When your furnace goes cold in the middle of the night or your air conditioner stops cooling on the hottest afternoon of the year, you need a technician who can actually show up today. We make same-day and emergency service available for urgent no-heat and no-cool situations, including evenings and weekends when a problem simply cannot wait until Monday morning.
We keep you posted from the first call until your system's running again. You will know who is coming, when they are arriving, and what they found when they get there. One call, and a technician is on the way.
Here's what most people get wrong about their HVAC system: they assume the cost question only gets answered after the work is done. That is not how we operate.
Before any repair, tune-up, or replacement begins, we give you straight answers about your furnace, AC, and ductwork, no surprises. The normal first step is a diagnostic or service-call inspection so we can tell you exactly what is going on and what it will take to fix it. From there, you get a clear estimate covering parts and labor before we proceed. Whether you are asking about furnace repair cost, AC repair cost, heat pump repair cost, or a full system replacement, you will know the number before we start.

Johnson County sits squarely in four-season Indiana weather. Summers are hot and genuinely humid. Winters bring real cold with freeze risk that pushes heating systems hard. That combination drives demand for reliable cooling, whole-system replacement cycles, heat pump adoption, and humidity control. The services below are the ones that come up most often in this area, and they are the ones we have built the most experience around over the past five decades.
When a furnace or central air system reaches the end of its useful life, replacing both units together is often the smarter move. Aging equipment loses efficiency, drives up utility costs, and starts failing at the worst possible times. In a climate where you genuinely need both heating and cooling to perform every year, a mismatched or worn-out system is a real problem. We handle full whole-home HVAC replacement, new furnace installation, and new AC unit installation, and we size and select equipment that fits your home and your budget. We stand behind every system we service, and that starts with getting the installation right.
Heat pumps have become a strong choice for Indiana homeowners who want efficient heating and cooling in a single system. A well-sized heat pump handles the moderate cold of a typical Greenwood winter efficiently and keeps the home cool through summer without a separate cooling system. We install and replace heat pumps for both ducted and ductless applications, including mini-split systems for additions, sunrooms, or spaces that need independent comfort control. We also provide ongoing heat pump repair and service to keep installed systems running at peak efficiency year after year.
Indiana summers bring humidity that a standard air conditioner alone cannot always manage. High indoor humidity makes a home feel warmer than it actually is, strains the cooling system, and can affect air quality over time. A whole-home dehumidifier works alongside your existing HVAC system to pull excess moisture out of the air consistently, not just when the AC happens to be running. We install whole-home dehumidification and humidity control systems, and we tie them into your existing equipment and thermostat so everything works together. Better humidity management is also a meaningful indoor air quality upgrade for families who deal with allergies or respiratory sensitivities.
Call today. Scheduled tomorrow. Comfortable by the weekend.
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 would otherwise become emergency calls. We perform spring and fall maintenance visits that cover the full system: refrigerant level and leak diagnosis, airflow measurement and correction, evaporator coil and air handler inspection, thermostat calibration, and a check of all the components that wear over time.
An annual HVAC inspection keeps your system efficient, extends equipment life, and gives you a clear picture of what is in good shape and what needs attention before it fails. We take pride in the HVAC work we leave behind, and that includes the routine maintenance visits that most people do not see but that make a real difference in how long a system lasts.
Let us handle the install and the permits.
For homeowners and property managers who want it done right, we bring the same standard of work to commercial accounts that we apply to every residential job. We service and repair commercial heating and cooling equipment, including rooftop units, commercial AC systems, and commercial heating systems for offices, retail spaces, and multi-unit properties. We also work with zoning and comfort-control systems for buildings that need different temperatures in different areas. If you manage a property in or around Greenwood and need a reliable HVAC contractor who shows up and follows through, give us a call.
We have been doing this work in Greenwood since 1976. That is fifty years of serving Johnson County families, landlords, and businesses, and every job in that time has carried our name on it. When you call us, you reach a local person who knows the area and takes your comfort seriously. Every job is handled by qualified HVAC technicians who know what they are doing and who care about the outcome.
We serve Greenwood and the surrounding communities throughout the county and the broader south Indianapolis area, including Bargersville, Whiteland, New Whiteland, Franklin, Trafalgar, and Edinburgh. If you are nearby and need heating or cooling help, we are your neighbors.
We keep your home comfortable in every season.
When you call, you reach a local person who can answer questions and get you on the schedule. We confirm the appointment window, let you know who to expect, and keep you posted as the visit approaches. You will not be left wondering whether anyone is actually coming.
For standard service calls, we typically schedule within a day or two depending on the time of year. For urgent no-heat and no-cool situations, we make same-day service available, including evenings and weekends. Call (463) 444-9782 and we will tell you exactly what we can do for your situation.
Check your thermostat settings and make sure the system switch is in the correct position, then check whether a tripped breaker has cut power to the unit. If those steps do not resolve it, call us. A system that will not start at all is exactly the kind of problem we handle on a same-day or emergency basis.
We provide a clear estimate covering parts and labor before any repair or replacement begins. The normal first step is a diagnostic or service-call inspection so we know exactly what the system needs. From there, you get the number before we proceed, not after.
If the technician finds additional problems during the inspection, we explain what was found and what it will cost to address before doing any extra work. We give you straight answers about your furnace, AC, and ductwork with no surprises. Nothing gets added to the scope without your approval first.
The most common factors are the age and condition of the equipment, the availability of parts, and whether related components like ductwork or the air handler need attention at the same time. A thorough diagnostic helps us identify those issues upfront so you are not caught off guard. We walk you through the full picture before any work begins.
We keep you posted from the first call until your system's running again. That means you know who is coming, when they are arriving, and what they found once they are on-site. If anything changes during the job, we tell you before we act on it.
The technician will introduce themselves, ask about what you have been experiencing, and then inspect the system before recommending any work. You will get a clear explanation of what was found and what it will take to fix it. Work performed by qualified HVAC technicians means the job is done correctly and the system is tested before anyone leaves.
Yes. We work with homeowners, landlords, property managers, and light commercial building owners throughout Greenwood and the surrounding Johnson County area. The same standard of work applies whether we are servicing a single-family home or a multi-unit commercial property.
We pick up the phone. We arrive on time. We check before we leave.

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.
