When it’s time for a new system, our team handles every detail of your air conditioning installation. We’ll help you choose the right size and model based on your home’s layout and cooling needs. Our technicians install to code, follow manufacturer standards, and walk you through how everything works before we leave.

Heat Pump Services

Heat pumps are an efficient, all-in-one solution for cooling and heating your home, but their performance in the summer depends on proper care. When the Indiana heat rises, you want a system that can handle it. Thiele offers full-service support to keep your heat pump cooling strong all season long.

When your system blows warm air, struggles to cool your space, or short cycles, you need expert heat pump repair. We quickly identify the issue—whether it’s a bad sensor, failing valve, or refrigerant loss—and fix it. Most repairs are completed the same day.

Heat Pump Maintenance

Seasonal heat pump maintenance improves airflow, protects internal components, and helps prevent cooling failures. We clean coils, test refrigerant, check wiring, and fine-tune the system so it’s ready for the months ahead. Maintenance also helps reduce energy bills.

Heat Pump Replacement

Older systems lose efficiency and cooling power, especially under heavy use. Our heat pump replacement service ensures you get a properly sized, energy-efficient model that can handle Indy’s summer heat. We remove the old unit and install the new one quickly and correctly.

Geothermal Heat Pump Services

Geothermal heat pumps are one of the most efficient ways to cool a home, using the steady temperature underground to remove heat from inside. These systems run quietly, save energy, and deliver consistent comfort, even on the hottest days in Indianapolis. Thiele offers complete geothermal cooling services—repairs, maintenance, installation, and full replacements.

Ductless Mini Split Services

Ductless mini split systems offer flexible, energy-efficient cooling without the need for traditional ductwork. Some homeowners use them to cool their entire home, while others rely on them for specific areas—like a home office, a finished attic, or a room that’s always too warm. No matter how you use yours, Thiele is here with the cooling services you need to get the most out of your mini split system.

If a mini split stops cooling, starts making noise, or shows an error code, our ductless mini split repair service can get it back on track. We troubleshoot indoor and outdoor components, replace faulty sensors or motors, and restore cool air quickly. Most issues can be resolved without replacing the unit.
