Daugherty Heating & Cooling has served Plainfield and the surrounding Hendricks County area since 1978. We handle heating and cooling for homes, rental properties, and commercial buildings throughout the region. Same-day appointments are available for urgent repairs, and we provide honest estimates before any work begins. Honest quotes. Code-compliant work. Reliable comfort. Call (463) 262-2951 to schedule service or get a quote today.
A home that heats and cools right is a comfortable home, and that standard applies just as much to a small rental unit as it does to a commercial office or a retail space. We cover the full range of HVAC work: repair, installation, system replacement, seasonal maintenance, and indoor air quality. Property managers and business owners rely on us for the same responsive service we bring to every residential call. We've worked this area long enough to know its homes. From the first call to the final system test, you get clear communication at every step, with work performed by qualified HVAC technicians who take the job seriously. We'll take care of the system from here.
Over the years, we've seen every kind of furnace, AC, and heat pump, and the problems that bring homeowners to the phone are usually the same handful. The AC is not cooling. It is blowing warm air. The system will not turn on at all. Rooms are too warm while others feel fine. Each of these points to something specific, and a proper diagnosis is the only way to get it right.
A service visit covers the full picture: checking refrigerant levels and looking for leaks, inspecting the condenser and compressor, testing airflow, and identifying any control issues. If the system needs a tune-up rather than a repair, we handle that too. A seasonal AC tune-up is one of the simplest ways to avoid a breakdown in the middle of a hot Indiana summer.
Same-day and emergency AC repair are available when the system goes down and waiting is not an option. Call (463) 262-2951 to request an estimate or get a technician on the way. We're ready to get your heating and cooling running again.
Whether this is your first HVAC repair or your tenth, a furnace that stops working in an Indiana winter is a problem that needs attention fast. A furnace not turning on, a system blowing cold air, or a heater that simply will not respond to the thermostat are all situations we handle every week during the heating season.
A furnace service visit starts with a full diagnostic. We check the heat exchanger, inspect the blower and air handler, assess the control board, and trace any error codes the system is throwing. The goal is a clear answer and a clear quote before any repair work begins.
We work on gas furnaces, electric furnaces, and heat pumps. If your system is a heat pump that is not keeping up with the cold, that falls under the same call. Emergency and same-day furnace repair are available when you have no heat and need a technician today. Call (463) 262-2951 for a quote or to get on the schedule. Call and we'll get your heat or AC back on.
Indiana runs the full four-season range. Summers in Plainfield are hot and genuinely humid, and winters bring the kind of cold that puts real demand on a furnace. That combination means the heating and cooling system in a local home works hard in both directions, and when equipment ages out or efficiency drops, the cost shows up fast. The three services below see heavy demand in this area for exactly that reason.
At some point, repair stops making financial sense. A system that is more than 15 to 20 years old, breaking down repeatedly, or running inefficiently is usually a better candidate for replacement than another service call. In Plainfield, the most common replacement scenario is the paired furnace-and-AC swap. Because both systems share the air handler and ductwork, replacing them together often makes sense for efficiency, compatibility, and long-term cost.
The replacement process includes sizing the new equipment to the home, removing the old units, installing the new system, and running a full test before we leave. All installation work is performed by qualified HVAC technicians. Call (463) 262-2951 to request an estimate on a replacement.
A heat pump moves heat rather than generating it, which makes it an efficient option for Indiana's shoulder seasons in spring and fall when temperatures are moderate. For homes that want to reduce reliance on a gas furnace or add cooling to a space that does not have it, a heat pump is a practical choice.
We install heat pumps for new systems and handle heat pump replacement when an existing unit has reached the end of its life. For rooms without ductwork, such as additions, garages, or finished basements, a ductless mini-split system delivers targeted heating and cooling without running new duct lines. We also service and repair heat pumps that are already installed. Call (463) 262-2951 for an estimate on heat pump installation or service.
Humidity is a real comfort issue in Indiana summers. A portable dehumidifier handles one room. A whole-home dehumidifier connects directly to the HVAC system and manages moisture levels throughout the entire house, which makes a meaningful difference in how the air feels and how well the AC performs.
High indoor humidity also raises the risk of mold growth and degrades air quality over time. Pairing a whole-home dehumidifier with a quality air filtration system addresses both problems at once. On the other side of the year, dry winter air is its own issue. We install whole-home humidifiers as well, so the system works for comfort in both seasons. Call (463) 262-2951 to talk through options for your home.
We handle a wide range of HVAC work beyond the services above. Prompt response, even for last-minute comfort calls, is something we take seriously across all of it.
Scheduling an HVAC tech shouldn't be complicated. We keep the process simple: call, describe what the system is doing, and we get a technician scheduled. For urgent situations, same-day appointments are available. For maintenance and planned installations, we work around your schedule.
On pricing, we believe in being direct. A technician visits, diagnoses the issue, and gives you a clear quote before any work starts. You know what the job will cost before we pick up a tool. We take pride in the HVAC work we leave behind, and that starts with honest communication about what the repair or installation actually involves.
Fair price each visit. On time each visit. Code-compliant every time.

A system that is more than 15 to 20 years old, breaking down repeatedly, or driving up energy bills is often a better candidate for replacement than another repair. If you are unsure, a diagnostic visit gives you a clear picture of the system's condition and what the options actually cost, so you can make an informed decision.
The visit includes a full diagnostic, a clear explanation of what the technician finds, and a quote for the repair or service. If the job is approved and completed that day, the labor and any parts used are covered in the agreed price. We do not add fees that were not in the quote.
Call us ahead of time and we will work out the access details together. For outdoor equipment like a condenser unit, access is usually straightforward. For indoor systems, we will talk through what arrangements make sense so the technician can get to the equipment and complete the job.

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.
