Schedule ServiceDuctless Mini Split Installation: Efficient Cooling and Heating Without the Ductwork
A ductless mini split is a heating and cooling system that doesn’t require ductwork to distribute air. Instead, it consists of two main components: an outdoor compressor and one or more indoor air handlers, connected by a small conduit. These systems allow for zoned climate control, meaning you can set different temperatures in different rooms, improving comfort and energy efficiency.
Mini split systems come in different configurations, including:
- Single-Zone Mini Splits: Perfect for heating and cooling one room, such as a bedroom or home office.
- Multi-Zone Mini Splits: Connect multiple indoor units to one outdoor compressor for whole-home comfort.
Whether you’re adding air conditioning to a historic home without ductwork or improving temperature control in an addition or garage, a ductless mini split could be the ideal solution.
Benefits of Installing a Ductless Mini Split
A ductless mini split gives you control over your home’s comfort like never before. Here’s how a mini split system works to make your home more efficient and enjoyable:
Energy Efficiency and Cost Savings
Mini split air conditioners and heat pumps use advanced inverter technology to adjust energy output based on demand, reducing wasted energy. Because they don’t rely on ductwork, they also avoid the energy losses that occur in traditional HVAC systems, helping homeowners save money on heating and cooling costs.
Zoned Climate Control
Unlike central air conditioners, ductless systems allow you to set different temperatures in different rooms. No more fighting over the thermostat! Each air handler operates independently, so everyone in your home can enjoy their preferred level of comfort.
Compact, Versatile Design
A ductless air conditioner is sleek and designed to blend into your space. Units can be mounted high on the wall, recessed into the ceiling, or even placed as floor units—giving you more flexibility than traditional HVAC systems.
Improved Indoor Air Quality
Without ducts collecting dust, mold, and allergens, ductless mini split air conditioners can help improve indoor air quality. Many models include advanced filtration systems to reduce allergens and pollutants further.
Quiet Operation
Mini split air conditioners are significantly quieter than traditional HVAC systems. With indoor units operating at as low as 19 decibels, they’re ideal for bedrooms, nurseries, and home offices where noise can be a concern.
How Are Ductless Mini Splits Installed?
Installing a ductless air conditioner is faster and less invasive than adding or extending ductwork for a traditional HVAC system. Here’s how it works:
- A small hole (about 3 inches) is drilled in the wall to connect the indoor and outdoor units.
- Refrigerant lines, electrical wiring, and a drain line are fed through the conduit.
- The indoor air handler is mounted on a wall, ceiling, or floor, depending on your preference.
- The outdoor compressor unit is securely placed in a location that allows for proper airflow.
- The system is tested, adjusted, and fine-tuned for optimal performance.
What Does a Mini Split Cost?
The cost of installing a ductless mini split depends on the number of zones, the type of system, and your home’s specific needs. At Thiele, we believe in transparent pricing—we’ll provide a detailed quote upfront, along with information on financing options, warranties, and available discounts.

Schedule ServiceDuctless Mini Split Repair: AC and Heating Issues, Solved
Ductless mini splits are built to last, but like any heating and cooling system, they need a little help from time to time. Maybe your unit isn’t cooling as well as it used to, your energy bills are creeping up, or your system just isn’t responding like it should. The good news? Most problems are fixable—if you catch them early.
Signs That You Need a Mini Split Repair
Your ductless mini split is designed to be low maintenance and highly reliable, but even the best systems can run into issues. Here’s how to tell if it’s time to call in the pros:
Weak or Uneven Cooling or Heating
Does your mini split air conditioner seem to be running, but your room still feels too warm (or too cold)? It could be low refrigerant, a clogged filter, or a blocked coil making your system work harder than it should.
Your Energy Bills Keep Climbing
If your energy bill has spiked and there’s no extreme weather to blame, your mini split might be overcompensating for a hidden issue. This could be anything from a failing compressor to restricted airflow—either way, it’s best to have it checked.
Your System Won’t Respond to Adjustments
If adjusting the temperature on your mini split AC doesn’t seem to do anything, you could be dealing with a faulty thermostat, sensor, or control board issue. If the system won’t turn on at all, it might be an electrical problem that needs immediate attention.
Ice or Water Buildup on the Indoor Unit
Notice ice forming on the evaporator coils or water pooling under your indoor unit? These are warning signs of low refrigerant, poor airflow, or a clogged drain line. Letting it go too long could lead to major damage to your system.
If you spot any of these signs, schedule a ductless mini split repair and we’ll take care of it—fast.
When Is a Mini Split Replacement Needed?
Even with great maintenance and timely repairs, every mini split system has a lifespan. Most ductless mini splits last 12 to 15 years, but if yours is starting to struggle, it might be time to weigh the cost of repairs versus replacing it altogether.
Here’s when it might make sense to replace your mini split AC:
- Your system is over 12 years old and losing efficiency.
- You’re calling for repairs more often than you used to.
- Your home isn’t staying comfortable, even after tune-ups.
- Your energy bills are going up, even though your usage hasn’t changed.
At Thiele, we’re not here to push a new system on you if you don’t need one. We’ll give you honest recommendations, whether that means repair work or a full system upgrade. Book an appointment now for your mini split repair and we’ll see what needs to be done.
Schedule ServiceDuctless Mini Split Maintenance: Helping Your Heat Pump Stay Reliable
Your ductless mini split works hard year-round to keep your home comfortable. But like any heating and cooling system, it needs routine maintenance to keep running at its best. Skipping maintenance can lead to clogged filters, inefficient performance, refrigerant leaks, and even costly system failures—all of which can be avoided with regular checkups.
A simple tune-up twice a year helps ensure that your mini split air conditioner is operating efficiently, keeping your energy bills low and extending the life of your system. It also helps maintain your manufacturer’s warranty, so if a covered part ever needs replacing, you won’t be left paying out of pocket.
To keep your mini split AC in top shape, we recommend scheduling maintenance twice a year in the spring and fall.
What Maintenance Do Ductless Air Conditioners and Heating Systems Need?
A ductless mini split might seem low-maintenance, but keeping it in top shape takes more than a quick wipe-down. Filters, coils, and refrigerant lines all need professional attention to ensure your system can do its job. Here’s what our technicians focus on during a mini split maintenance appointment:
Cleaning the Filters
Over time, air filters collect dust, pet dander, and debris, which can restrict airflow and reduce efficiency. Dirty filters force your system to work harder, increasing energy costs and reducing comfort. Cleaning or replacing filters every one to three months helps improve indoor air quality and keeps your mini split air conditioner operating at peak performance.
Inspecting Refrigerant Lines
Your mini split AC relies on refrigerant to transfer heat efficiently. If there’s a refrigerant leak, your system may struggle to cool your home, causing higher energy bills and potential compressor failure. During maintenance, we check for leaks, verify refrigerant levels, and recharge if necessary.
Cleaning the Coils
Both the evaporator coil (inside) and the condenser coil (outside) can collect dirt, dust, and grime. When these coils become dirty, your system can’t transfer heat effectively, reducing efficiency and forcing your unit to work harder. Regular cleaning ensures optimal cooling and heating performance while extending the lifespan of your system.
Testing Electrical Connections
A mini split system relies on electrical components to operate smoothly. Loose or faulty wiring, sensors, or connections can cause your system to malfunction, shut down unexpectedly, or run inefficiently. Our technicians thoroughly inspect all electrical components to ensure safe and reliable operation.

Schedule ServiceFAQs: Frequently Asked Questions About Ductless Mini Split Systems
How many indoor units will I need for my home?
The number of indoor units you need depends on your home’s layout and the areas you want to cool or heat. A single-zone system works well for one room, while a multi-zone system can connect multiple indoor units to one outdoor compressor. Our technicians will evaluate your home and recommend the right configuration to provide consistent comfort throughout your space.
How will a ductless mini split impact my indoor air quality?
Ductless mini splits can improve your indoor air quality by eliminating the need for traditional ductwork, which can collect dust, allergens, and other pollutants. Many systems also feature advanced filtration to capture particles and enhance air quality, making them ideal for households with allergy or asthma concerns.
Can a ductless mini split replace a furnace and air conditioner?
Yes, a ductless mini split can replace both a furnace and air conditioner in many Indianapolis homes, providing efficient heating and cooling year-round. Since mini splits function as heat pumps, they work well in most conditions, but Indiana’s extreme cold snaps can reduce their efficiency. For well-insulated homes, a ductless system may be enough, but in sub-zero temperatures, a backup heat source like a gas furnace or electric heater might be needed. Thiele’s experts can assess your home and recommend whether a standalone mini split or a hybrid system is the best choice for year-round comfort.
Can I control a ductless mini split system with a smart home device?
Yes, many ductless mini split systems are compatible with smart home devices and can be controlled through apps or voice commands. Features like Wi-Fi connectivity allow you to adjust temperatures, set schedules, and monitor energy use from anywhere. We’ll help you choose a system with smart capabilities to make managing your comfort even easier.
What is the noise level of a ductless system?
Ductless mini splits are known for their quiet operation. Indoor units typically produce noise levels comparable to a gentle hum, making them ideal for bedrooms and living spaces. Outdoor units are also designed to run quietly, so you won’t have to worry about disturbances inside or outside your home.
How can I improve the energy efficiency of my ductless air conditioner?
To maximize efficiency, clean or replace filters regularly, keep the outdoor unit free of debris, and schedule routine maintenance to ensure all components are functioning properly. Using smart thermostat settings and zoning features can also help reduce energy waste by only conditioning the areas you’re using.
What is the difference between an inverter and non-inverter ductless mini split?
Inverter mini splits adjust their compressor speed based on the cooling or heating demand, which makes them more energy-efficient and better at maintaining consistent temperatures. Non-inverter models run at a fixed speed, cycling on and off, which can lead to higher energy use and less precise climate control. We typically recommend inverter systems for optimal performance.
How can I troubleshoot my ductless mini split?
If your mini split isn’t working properly, start by checking the basics: ensure the power is on, clean or replace the filters, and verify that the thermostat settings are correct. If the issue persists, such as leaking, icing, or unusual noise, contact Thiele for professional assistance. Attempting complex repairs on your own can lead to further damage or void your warranty.
