Daugherty Heating & Cooling has been keeping Plainfield homes and businesses comfortable since 1978. We serve Plainfield and the surrounding Hendricks County communities with residential and commercial heating and cooling, from a single-family home that needs a furnace tune-up to a multi-unit property that needs a full system replacement. Clear communication from the first call to the final test is how we work every time. Honest quotes. Code-compliant work. Reliable comfort. Call (463) 262-2951 for a quote.
Over the years, we've seen every kind of furnace, AC, and heat pump, and we know what it takes to keep them running through Indiana's full range of seasons. We handle AC repair and service, furnace repair and replacement, heat pump service, ductwork repair and sealing, thermostat and smart-control installation, indoor air quality and air filtration, seasonal maintenance, and emergency service. Whether you're a homeowner managing your own comfort, a landlord keeping tenants warm in winter, a property manager juggling multiple units, or a business owner who needs reliable climate control, we handle it all. We take pride in the HVAC work we leave behind, and that shows in every job we complete. We're ready to get your heating and cooling running again.
Whether this is your first HVAC repair or your tenth, a system that stops cooling in the middle of an Indiana summer is never a small problem. When your AC is blowing warm air, cycling on and off without cooling the space, or not running at all, we diagnose the cause and get it sorted. That means checking the condenser and compressor, testing for refrigerant leaks, and working through airflow and duct issues that might be robbing you of comfort. A spring AC tune-up is one of the best ways to catch small problems before the heat arrives. If your system stops working in the middle of the season, same-day service is available. Call (463) 262-2951 and we will get someone out.
A furnace that stops working in January is an emergency, not an inconvenience. When you have no heat in the house, we respond fast. We diagnose furnaces that are not heating, blowing cold air, short-cycling, or shut down entirely. Work is performed by qualified HVAC technicians who know how to trace the problem and fix it correctly. Beyond emergency calls, a fall furnace tune-up is the smartest way to head into winter. Annual maintenance keeps the equipment running efficiently and helps avoid the breakdowns that always seem to happen on the coldest nights of the year. Call (463) 262-2951 to schedule service or request a quote.
Heat pumps are a practical fit for Indiana's mixed climate, providing both heating and cooling from a single system. When a heat pump stops heating in winter or stops cooling in summer, we diagnose the issue and restore performance. We handle heat pump maintenance, emergency repair, and seasonal checks. If your system is struggling to keep up or running but not conditioning the air the way it should, call us and we will take a look. That service naturally connects to heat pump installation as well, which we cover in the regional services section below.
Leaky or damaged ductwork quietly drives up energy costs and leaves some rooms too warm and others too cool. We repair and seal ductwork so your system delivers conditioned air where it is supposed to go. A thermostat upgrade, including a smart thermostat that learns your schedule and adjusts automatically, is one of the simpler improvements that pays off quickly in comfort and efficiency. On the air quality side, we install whole-home air filtration and air purification systems that work with your existing HVAC equipment to reduce dust, allergens, and airborne particles. Better filtration makes a real difference, especially in older homes where duct systems have accumulated years of buildup. We'll take care of the system from here.
Hendricks County gets the full Indiana experience: hot, humid summers and winters that can push well below freezing. That combination puts real demands on heating and cooling equipment, and it shapes which services matter most in this area. The three services below come up regularly in Plainfield because of exactly that climate reality.
When equipment is old enough, repairs stop making financial sense. Repeated breakdowns, rising energy bills, and systems that simply can no longer keep up are all signs that replacement is the right move. Indiana's four-season climate means you need both a furnace and an air conditioner performing reliably, so a full system replacement often addresses both at once. We walk through the assessment with you, help you choose equipment that fits the home or building, and handle the installation with qualified technicians who test the system before they leave. For pricing, the right answer depends on the equipment, the home, and what is already in place. Call (463) 262-2951 for a quote and we will give you a clear number.
Heat pump adoption is growing across Indiana as homeowners look for a single system that handles both heating and cooling efficiently. In Hendricks County's temperature range, a properly sized heat pump performs well through most of the heating season and keeps cooling costs manageable in summer. For additions, garages, sunrooms, or spaces without existing ductwork, a ductless mini-split system is often the cleanest solution. We size, install, and commission the equipment so it runs correctly from the first day. If you are weighing a heat pump against a traditional furnace-and-AC setup, call us and we will walk through the options with you. Call (463) 262-2951 to get started.
Indiana summers are humid, and that humidity follows the air indoors. High indoor humidity makes a home feel warmer than it is, strains the air conditioner, and creates conditions where mold and mildew can take hold. A whole-home dehumidifier integrates directly with your existing HVAC system and manages moisture across the entire house, not just one room. The result is better comfort, better air quality, and less work for your cooling equipment. We handle the installation and calibrate the system to the home. Prompt response, even for last-minute comfort calls, is something we make a point of. Call (463) 262-2951 to schedule an assessment.
Scheduling an HVAC tech shouldn't be complicated, especially when your heat or AC is completely down. We take emergency calls for no-heat situations, AC failures, and HVAC systems that have stopped working entirely. That includes homeowners, landlords managing rental properties, property managers with multiple units, and business owners who cannot afford a day of downtime in an office or retail space. Same-day service is available, and when you call, you reach someone who can actually help. Local crew. Real technician on the phone. Quick to respond. Call (463) 262-2951 and we will get someone out to you.
A home that heats and cools right is a comfortable home, and the same holds true for an office, a retail space, or a rental unit. We work with single-family homeowners on everything from seasonal tune-ups to full system replacements. For landlords and property managers, we handle service calls across multiple units and can set up scheduled maintenance so equipment issues get caught before they become tenant complaints. Commercial clients in the Plainfield area count on us for reliable heating and cooling maintenance, system repairs, and equipment replacement when the time comes. We've worked this area long enough to know its homes. That means we understand the housing stock, the seasonal demands, and what it takes to keep systems running year after year. Call and we'll get your heat or AC back on.
We are based in Plainfield and serve customers throughout Hendricks County and the surrounding communities. That includes Avon, Brownsburg, Danville, Mooresville, Camby, and Clermont, along with the neighborhoods and subdivisions in between. If you are nearby and need heating or cooling service, give us a call and we will let you know we can get to you.
A no-heat situation in winter, a complete AC failure during a heat stretch, or a system that has shut down entirely and will not restart all qualify as emergencies. If the system is down and waiting is not a safe or reasonable option, call (463) 262-2951 and we will get a technician out the same day.
The technician runs a full diagnostic that includes checking controls, testing airflow, inspecting key components, and in some cases tracing error codes the system is throwing. From there, they explain what they found in plain language and give you a quote before any repair work begins.
A system that is more than 15 to 20 years old, has broken down multiple times in a short period, or is no longer keeping up with the home's heating or cooling load is usually a better candidate for replacement. Repeated repair costs add up quickly, and a new system typically runs more efficiently, which reduces energy costs over time.
We start with an assessment of the existing setup and the building's heating and cooling needs, then help you select equipment that fits the space. From there, we remove the old units, install the new system, and run a full test before we consider the job done. All installation work is performed by qualified HVAC technicians.
A heat pump is a practical option for Indiana's mixed climate, especially during the shoulder seasons when temperatures are moderate. If you want a single system that handles both heating and cooling efficiently, or if you are adding comfort to a space without existing ductwork, a heat pump or ductless mini-split is worth a serious look. Call (463) 262-2951 and we will walk through the options with you.
Common signs include the system blowing warm air, running constantly without cooling the space, cycling on and off more frequently than usual, or making noises it did not make before. Any of these points to something specific, and a diagnostic visit is the right way to find out what is actually going on.
A furnace that blows cold air or short-cycles is often dealing with a control issue, a problem with the heat exchanger, or a sensor that is reading incorrectly. These are not issues to ignore, because a furnace that cannot complete a full heating cycle will drive up energy costs and may be heading toward a complete failure. A diagnostic visit will identify the cause and give you a clear path forward.
An AC that runs without cooling is often low on refrigerant due to a leak, struggling with a failing compressor, or blocked by a clogged or frozen evaporator coil. In some cases, the problem is airflow rather than the equipment itself. We diagnose the full system to find the actual cause rather than guessing at a fix.
Unusual sounds are almost always a sign that something inside the system is worn, loose, or failing. Banging can point to a loose component in the blower or air handler. Squealing often means a belt or bearing is going. Rattling may indicate debris in the system or a panel that is not seated correctly. Any of these is worth a call before the problem gets larger.
A frozen evaporator coil is usually caused by restricted airflow, low refrigerant, or a dirty coil that cannot transfer heat properly. When the coil freezes, the system cannot absorb heat from the indoor air, which means the air coming out of the vents stays warm even though the system is running. We diagnose the underlying cause, not just the symptom.
A system that is struggling works harder and longer to reach the temperature the thermostat is calling for. That extra run time shows up directly on the energy bill. If your costs have risen without a change in usage habits, it is often a sign the system has lost efficiency and a diagnostic visit is worth scheduling.
After a repair or installation, the technician runs the system through a full operational test, checking that it heats or cools correctly, that controls are communicating, and that airflow is where it should be. We do not consider the job done until the system is confirmed to be working correctly.
Indiana summers bring genuine humidity, and that moisture follows the air indoors. A whole-home dehumidifier connects directly to the existing HVAC system and manages moisture levels throughout the house, which reduces the load on the air conditioner and improves how the air feels. We handle the installation and calibrate the system to the home before we leave.
We've served this area long enough to know what works, and we bring that experience to every job, residential or commercial. Work is performed by qualified HVAC technicians who show up prepared, communicate clearly, and leave the system running correctly. Fair price each visit. On time each visit. Code-compliant every time. Call (463) 262-2951 to request a quote or schedule service. We are ready to help.
We handle the full range of heating and cooling work for homes, rental properties, and commercial buildings throughout Plainfield and Hendricks County. Whether you need a same-day repair, a seasonal tune-up, or a full system replacement, we show up with the right equipment and give you a clear quote before any work begins.

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.
