A home that heats and cools right is a comfortable home, and for nearly five decades, Daugherty Heating & Cooling has been the company Plainfield families and businesses call when comfort is on the line. Founded in 1978, we have spent 48 years learning the homes, the seasons, and the people of this area. We've worked this area long enough to know its homes. From a furnace that quits on a January night to an AC that stops cooling in the middle of July, we show up, we diagnose honestly, and we get the system running. We work with homeowners, property managers, and business owners across Hendricks County, and we take pride in the HVAC work we leave behind. Honest quotes. Code-compliant work. Reliable comfort. We're ready to get your heating and cooling running again.
Over the years, we've seen every kind of furnace, AC, and heat pump, and we know what it takes to keep them running well in an Indiana climate that swings from humid summers to cold winters. Our team handles the full range of residential and commercial HVAC work, from a quick repair on a system that's acting up to a full installation when it's time to replace aging equipment. Qualified HVAC technicians handle every job, and every visit is built around honest communication and code-compliant work. Whether you manage a single-family home or a commercial property, we have the experience to take care of it.
When your air conditioner stops cooling or starts blowing warm air, the problem could be anywhere from a refrigerant leak to a failing compressor to a clogged evaporator coil. We diagnose the issue, explain what we find, and give you a clear picture of what the repair or replacement will involve before any work begins. A typical AC visit covers a full system inspection, condenser and compressor service, evaporator coil cleaning and repair where needed, and refrigerant leak diagnosis when the situation calls for it. We also handle new central air installations when a replacement makes more sense than another repair. For urgent situations, same-day service options are available so you are not left waiting through the heat.
Indiana winters are not mild, and a furnace that stops working in January is not a problem you can put off. We handle furnace repairs across all major makes and models, including systems that are blowing cold air, cycling on and off, or simply not turning on at all. When a furnace has run its course, we handle full replacements and make sure the new system is sized and installed correctly for the home. Before the cold season hits, a furnace tune-up is one of the best ways to catch small issues before they become expensive ones. Call and we'll get your heat or AC back on.
Heat pumps are a practical choice for Indiana homes, especially during the shoulder seasons when the weather sits between heating and cooling territory. We service and repair heat pumps that are not heating or cooling properly, making unusual noises, or losing efficiency. We also install new heat pump systems for homeowners who want an energy-efficient alternative to a traditional furnace and AC combination. Our technicians are familiar with the full range of heat pump equipment and can help you figure out whether repair or replacement is the right call.
Mini-split and ductless systems are a strong fit for home additions, older homes without existing ductwork, garages, and any space where running new ducts would be impractical or too costly. We install and service ductless mini-split systems for both heating and cooling, and we can help you figure out whether a single-zone or multi-zone setup makes sense for your situation. If a ductless system you already have is not performing the way it should, we diagnose and repair those too.
When a system reaches the end of its useful life, a full replacement is often the more cost-effective path forward. We handle complete HVAC system replacements for homes and commercial properties, starting with a thorough assessment of the existing setup and the building's heating and cooling needs. From there, we help you select equipment that fits the space and the budget, handle the full installation, and run a final system test before we consider the job done. Clear communication from the first call to the final test is how we approach every replacement project, so you always know where things stand and what to expect. Work is performed by qualified HVAC technicians on every installation, and we hold every job to code-compliant standards. We'll take care of the system from here. Fair price each visit. On time each visit. Code-compliant every time.
We've served this area long enough to know what works, and some of the most common comfort complaints we hear come down to three things: a thermostat that is not communicating well with the system, ductwork that is leaking conditioned air before it reaches the room, and indoor air that is too humid, too dry, or carrying more allergens and particles than it should.
Smart thermostats and programmable controls give homeowners and building managers more precise control over their comfort and their energy use. We install and configure a range of thermostat and smart-control options and make sure the new control is set up correctly for the system it is running.
Leaky or damaged ductwork quietly drives up energy bills and creates uneven temperatures throughout a home. We inspect, repair, and seal ductwork to bring airflow back in line and reduce the energy loss that comes from conditioned air escaping before it reaches the living space.
Indiana's climate swings between high summer humidity and dry winter air, and both extremes affect comfort and air quality inside the home. We handle indoor air quality and air filtration work, including air purifiers, filtration upgrades, and whole-home humidity control for homes that need it. If your air feels off or your system seems to be working harder than it should, it is worth a call to find out why.
Property managers and business owners have different priorities than residential customers. Downtime costs money, tenants and customers notice when the temperature is off, and a slow response from a contractor makes everything harder. We work with commercial clients across Hendricks County on everything from rooftop unit repair and service to boiler repair and hydronic heating work. We understand that a commercial HVAC call often needs to move quickly, and we bring prompt response, even for last-minute comfort calls. Whether you manage an office building, a restaurant, a retail space, or a multi-unit property, we can get a qualified technician on site and get the system back up. Call us to talk through what your property needs and get a straightforward estimate.
Whether this is your first HVAC repair or your tenth, the value of keeping up with seasonal maintenance is something most homeowners come to appreciate after one expensive breakdown. A spring tune-up on your air conditioner and a fall tune-up on your furnace are the two best investments you can make in your system's reliability. We check refrigerant levels, clean components, test controls, and flag anything that looks like it is heading toward a problem. Catching a worn part before it fails is almost always less expensive than an emergency repair.
When something does go wrong, we offer same-day scheduling options and emergency HVAC service for no-heat and no-cool situations. A system that goes down in the middle of winter or during a summer heat stretch is not something you should have to wait days to fix. We keep our schedule flexible enough to respond when it matters. Local crew. Real technician on the phone. Quick to respond.
Scheduling an HVAC tech shouldn't be complicated. When you call us, you reach someone who can talk through what you are experiencing, help you decide whether it sounds like a repair or a maintenance issue, and get a technician scheduled without a lot of back and forth. When the technician arrives, they will diagnose the system, explain what they find in plain language, and give you a clear quote before any work starts. No surprise fees. No work that begins before you have agreed to it. We explain what the job involves and what it will cost, and we stick to that. We believe that clear communication from the estimate through the final invoice is what keeps customers coming back, and it is the only way we know how to do business.
We are based in Plainfield and serve the full Hendricks County area and the communities around it. If you live or manage property nearby, we are close and ready to help. Our service area includes:
We know these roads and these neighborhoods. We've worked this area long enough to know its homes, and that familiarity shows up in how quickly we can assess a system and how accurately we can estimate a job. If you are not sure whether you fall within our service area, give us a call and we will let you know.
We have been serving Plainfield and the surrounding area since 1978, which puts us at 48 years of local HVAC work. That history means we know the homes, the seasonal patterns, and the equipment common to this part of Indiana in a way that takes years to build.
We work with single-family homeowners, landlords managing rental properties, property managers with multiple units, and business owners who need reliable climate control. Whether it is a routine tune-up for a homeowner or an emergency repair at a commercial property in Hendricks County, we handle it with the same level of care.
Yes, we are locally owned and personally accountable to the community we work in. When you call, you reach a real local person, and when the technician shows up, it is someone who knows this area. That local accountability shapes how we approach every job.
If a customer calls because something is not working the way it should after we completed a job, we take that seriously and address it. We take pride in the HVAC work we leave behind, and that means standing behind it when a question comes up.
Work is performed by qualified HVAC technicians who diagnose accurately, communicate clearly, and complete the job to code. We do not cut corners on the work itself, and we do not leave a job until the system has been tested and confirmed to be running correctly.
Clear communication from the first call to the final test is how we approach every job. The technician explains what they find before any work starts, walks you through what the repair or installation involves, and confirms the system is working before they leave. You are never left guessing about what was done or why.
For urgent situations, same-day appointments are available. For planned maintenance and installations, we work around your schedule. When you call during our operating hours, you reach someone who can get a technician scheduled without a lot of back and forth.

How do I know if my system needs a repair or a full replacement?
A system that is more than 15 to 20 years old, breaking down repeatedly, or driving up energy bills is usually a better candidate for replacement than another repair. If you are not sure, a diagnostic visit gives you a clear picture of the system's condition and what each option actually costs so you can make an informed decision.
What are the signs that my AC or furnace is failing?
Common signs include the system not heating or cooling to the set temperature, unusual noises like banging or grinding, short cycling where the unit turns on and off frequently, and a noticeable rise in energy bills without a change in usage. Any of these is a good reason to call and have the system looked at.
Why is one room in my home hotter or colder than the rest?
Uneven temperatures are often caused by duct leaks, a blocked or undersized vent, or a system that is not properly sized for the home. A duct inspection usually identifies the source quickly. In some cases, a zoning adjustment or duct repair is all it takes to balance the house out.
Transparent Upfront Pricing
We give you a clear quote before any work begins. No surprise fees, no work started without your approval.
How often should I schedule maintenance and tune-ups?
Twice a year is the standard recommendation: a spring tune-up before the cooling season starts and a fall tune-up before heating season. Each visit covers the key components for that season and catches small problems before they turn into expensive repairs.
What does a seasonal tune-up actually include?
A tune-up covers a full inspection of the system's components, filter check, airflow assessment, and a review of any parts showing wear. For an AC tune-up, we also check refrigerant levels. For a furnace tune-up, we inspect the heat exchanger and burner. The goal is to confirm the system is ready to run efficiently through the season.
Can a dirty filter or coil really hurt my system's performance?
Yes, significantly. A clogged filter restricts airflow and forces the system to work harder, which raises energy costs and puts extra strain on the blower and compressor. A dirty evaporator or condenser coil reduces the system's ability to transfer heat. Both are easy to address and worth staying on top of.
Same-Day and Emergency Availability
We are available every day from 8:30 AM to 10:00 PM, including weekends, for no-heat and no-cool situations that cannot wait.
What causes a system to short-cycle?
Short cycling, where the system turns on and off more frequently than normal, is often caused by an oversized system, a refrigerant issue, a dirty filter, or a failing control component. It puts extra wear on the equipment and should be diagnosed rather than ignored. A service visit will identify the cause.
How do estimates and pricing work?
A technician visits, runs a full diagnostic, and gives you a clear quote before any work begins. No work starts until you have agreed to the price, and there are no fees added after the fact. You know what the job will cost before we pick up a tool.
Work Performed by Qualified HVAC Technicians
Every repair, installation, and tune-up is handled by trained technicians who take the job seriously and test the system before they leave.
Do I need to be home when the technician arrives?
For indoor equipment like a furnace or air handler, someone does need to be present or arrangements need to be made in advance. For outdoor equipment like a condenser unit, access is often more straightforward. Call ahead and we will work out the details so the technician can get to the equipment and complete the job.
What is the difference between a heat pump and a furnace, and how do I choose?
A furnace generates heat by burning fuel or using electric resistance, while a heat pump moves heat from one place to another. Heat pumps are efficient during Indiana's moderate spring and fall temperatures but may need a backup heat source during the coldest stretches of winter. We can walk you through the options based on your home's setup and your priorities.
How does whole-home humidity control improve comfort?
A whole-home dehumidifier connects directly to the HVAC system and manages moisture throughout the entire house, not just one room. In Indiana's humid summers, that makes a real difference in how the air feels and how efficiently the AC runs. A whole-home humidifier addresses the opposite problem in winter, when dry air causes discomfort and can affect woodwork and flooring.
