Thiele Heating & Air Condtioning

We’ve been helping Indianapolis and Central Indiana stay comfortable since 1883. As a locally and family-owned HVAC provider, we value the long-term relationships we build with the people and communities we serve. Our experienced technicians average more than 20 years in the field, bringing practical knowledge to every residential and light commercial heating and cooling job. We focus on responsive service, transparent pricing, and recommendations suited to each property rather than treating a visit as a one-time service call.

Our team installs, repairs, replaces, and maintains furnaces, boilers, central air conditioners, air-source and geothermal heat pumps, and ductless mini-split systems. We work with gas, oil, and electric furnaces and service equipment from all major HVAC manufacturers. As a Bryant Factory Authorized Dealer, we also offer Bryant heating and cooling equipment. For healthier, more comfortable indoor air, we provide humidifiers, dehumidifiers, air purifiers, and other indoor air quality solutions. Our maintenance plan includes priority service, exclusive discounts, and additional benefits designed to make ongoing equipment care more convenient.

When heating or cooling fails unexpectedly, we offer 24-hour emergency repair service. Our technicians travel in fully stocked trucks so we can complete most heating repairs during the initial visit, and new heating installations can often be scheduled for the following day. We serve Indianapolis and Marion County, including Irvington, East Gate, and Devington, as well as communities such as Beech Grove, Speedway, Greenwood, Plainfield, Avon, Brownsburg, Fishers, Mooresville, Carmel, Noblesville, Zionsville, and Westfield. Whether you need routine maintenance, help with a small equipment problem, or a complete system replacement, we’re ready to help you find an appropriate solution for your home or commercial space.
