Whether you’re upgrading an outdated system or installing central air conditioning for the first time, our team ensures a seamless process from start to finish. We help you select the right air conditioning unit based on your home’s size, SEER (Seasonal Energy Efficiency Ratio) rating, and cooling needs, ensuring powerful, even cooling for years to come.

A struggling air conditioner can quickly make your home uncomfortable, especially in the peak of an Indiana summer. If your AC unit is blowing warm air, making loud noises, or cycling on and off too often, it’s time for professional air conditioner repair. Our expert technicians diagnose the issue, whether it’s low refrigerant, a frozen coil, or an electrical problem, and restore your air conditioning system quickly.
Air Conditioning Maintenance
Routine air conditioning maintenance extends the lifespan of your system and helps prevent costly breakdowns. We recommend scheduling an AC tune-up in the spring to get your air conditioning unit ready for summer. Our AC maintenance tune-ups include cleaning the coils, checking refrigerant levels, tightening electrical connections, and ensuring proper airflow to keep your system running strong.
Air Conditioning Replacement
If your air conditioning system is over 10–15 years old, struggles to keep up with cooling demands, or needs frequent repairs, it may be time for an air conditioning replacement. We install high-efficiency air conditioners that provide better cooling while lowering energy bills. Our team helps you choose the best air conditioning unit for your home and ensures a smooth installation with minimal disruption.
Schedule ServiceHeat Pump Services
A heat pump provides year-round heating and cooling, making it an energy-efficient alternative to traditional HVAC systems. Instead of generating heat, it transfers warmth in and out of your home to maintain the perfect indoor temperature. We have all the heat pump cooling services you need in the Indianapolis area.
Heat Pump Installation
Thiele Heating & Air Conditioning installs air-source and geothermal heat pumps, helping you choose the best system for your space. We handle everything in your heat pump installation—from proper system sizing to expert installation—so you get even temperatures, reliable performance, and lower energy bills.
Heat Pump Repair
A heat pump should switch between heating and cooling with ease, but when something’s wrong, you’ll notice. Weak airflow? Inconsistent temperatures? Loud noises? It could be low refrigerant, a malfunctioning sensor, or a failing compressor. No matter the issue, our skilled HVAC technicians diagnose the problem fast and get your system running right again with a quick heat pump repair.
Heat Pump Maintenance
Because heat pumps run all year, especially in the summer, they need a little extra care to stay in top shape. That’s why we recommend biannual maintenance—once in spring, once in fall—to keep it working efficiently. A heat pump tune-up includes cleaning coils, checking refrigerant, inspecting electrical components, and ensuring smooth operation.
Heat Pump Replacement
If your heat pump is struggling to heat or cool properly, breaking down often, or nearing 15 years old, it’s time to consider a heat pump replacement. Newer models offer quieter operation, better humidity control, and improved efficiency, saving you money on energy bills. Thiele Heating & Air Conditioning will help you choose the right high-performance heat pump and get it installed quickly so you can enjoy better comfort year-round.

What Air Conditioner Is Right for Me?
If you’ve only ever thought about a central air conditioning unit, you’re not alone—but it’s not the only option anymore. There are several types of air conditioning systems, each with unique advantages depending on your home’s layout, energy efficiency goals, and cooling needs. Whether you want a traditional AC, a heat pump, or a ductless system, Thiele Heating & Air Conditioning will help you choose a system that keeps your home comfortable while maximizing energy savings.
Central Air Conditioners
Central air conditioning systems cool your entire home through a network of ducts that distribute air evenly. These systems are ideal for homes with existing ductwork and provide consistent cooling in every room. If you want a powerful, whole-home cooling solution, central air conditioning is a great choice.
Heat Pumps
A heat pump provides both heating and cooling by transferring heat rather than generating it. These systems are energy-efficient and work well in moderate climates like Indianapolis, making them a great alternative to traditional AC and furnace setups. Heat pumps are perfect for homeowners looking for an all-in-one solution that reduces energy consumption.
Ductless Mini Splits
Ductless mini split systems allow for zoned cooling, letting you set different temperatures in different rooms. These systems work well in homes without ductwork, older homes, additions, garages, and sunrooms. If you need customized comfort without the hassle of ductwork installation, a ductless air conditioning system is an excellent choice.
As a Bryant Authorized Dealer, Thiele Heating & Air Conditioning installs some of the most efficient, durable cooling systems available. We also service and install air conditioning equipment from other leading manufacturers, helping you find the best fit for your home’s cooling needs.

Learn MoreWhat to Look for in an Air Conditioning Company
There’s no shortage of HVAC companies in Fishers and the surrounding Central Indiana area, but not all of them deliver the same level of service. When your comfort is on the line, you want to feel confident you’re choosing a company that won’t cut corners or leave you second-guessing.
If you’ve been disappointed by your current provider—or stuck with the one who installed the system before you bought your home—you don’t have to settle. The right HVAC partner will earn your trust with every visit, not just show up when it’s convenient for them. Here’s what to keep in mind when choosing the best air conditioning company for your home:
Proven Experience With Local Homes and Air Conditioning Systems
Look for a team that knows how to work with homes just like yours. Companies with deep roots in your area understand the regional climate, building styles, and common system issues—and they’ve likely seen and fixed it all before.
Certified Heating and Cooling Technicians Who Keep Learning
Make sure your HVAC techs are certified, insured, and trained to handle the latest equipment, tools, and safety protocols. Ongoing training is a sign they take their craft seriously.
Clear Communication and Honest Pricing
Great service isn’t just about fixing the issue—it’s about how you’re treated along the way. The right company will explain the work clearly, offer honest quotes upfront, and never pressure you into repairs or upgrades you don’t need.
Full-Service Support Beyond Just Repairs
Whether you need a quick fix, a system tune-up, or a brand-new installation, your HVAC company should be able to handle it all. Look for providers who offer complete service options so you don’t have to juggle multiple contractors.

Schedule ServiceFrequently Asked Questions About Air Conditioner Repair, Maintenance, and More
How do I know what refrigerant is in my air conditioner?
Most air conditioners installed before 2010 use R-22 (Freon), while newer models use R-410A (Puron), a more environmentally friendly option. You can check your system’s nameplate and user manual or contact Thiele Heating & Air Conditioning, and we’ll identify it for you.
How much does it cost to install air conditioning?
Air conditioning installation costs vary based on factors like system size, efficiency rating, and home layout. A ductless system or central air installation will have different price points. Thiele provides upfront quotes and financing options to make your new AC installation affordable.
What does the SEER rating of a central air system mean?
SEER (Seasonal Energy Efficiency Ratio) measures how efficiently an air conditioner converts electricity into cooling over a season. The higher the SEER rating, the more energy-efficient the system. Modern units range from 14 SEER to 25+ SEER, helping lower utility costs.
How often should I service my air conditioning system?
Your AC unit should be serviced at least once a year, ideally in the spring, to ensure it’s clean, running efficiently, and free from potential issues before peak cooling season. Thiele offers a maintenance plan for routine tune-ups and savings on repairs.
What size air conditioning system do I need for my space?
Choosing the right AC size depends on square footage, insulation, and climate. Too large, and it short cycles; too small, and it struggles to cool efficiently. Our technicians perform detailed load calculations to recommend the best system for your home.
What are the different types of air conditioning systems you can buy?
The most common AC options are central air conditioning, heat pumps, and ductless mini splits. Central AC is great for whole-home cooling, heat pumps provide both heating and cooling, and ductless systems are ideal for zoned comfort without ductwork.
Can any home have central air?
In most cases, yes—central air conditioning can be added to nearly any home. Homes with existing ductwork typically make the process easier, but even homes without ducts can often be retrofitted. If ductwork isn’t practical for your layout, we can recommend alternative solutions like ductless mini splits.
What is a cheaper option for an air conditioning system?
If you’re looking for a more budget-friendly cooling solution, ductless mini splits are often a cost-effective alternative to full central air systems—especially for smaller homes, additions, or homes without ductwork. They’re efficient, flexible, and quick to install.
Can I install an air conditioning system myself?
Installing an AC system requires specialized tools, refrigerant handling certification, and knowledge of local building codes. A DIY installation can lead to safety risks, improper performance, and voided warranties. Trust the professionals at Thiele for expert AC installation.
