Indianapolis HVAC Quotes

A new central AC unit in Indianapolis costs between $3,500 and $7,500 installed, depending on the size of your home, SEER efficiency rating, and brand. A 14 SEER system is the baseline, while 16+ SEER high-efficiency units cost more upfront but save 20–40% on monthly cooling bills. Most homes in the Indy metro need a 2.5–4 ton system.

Furnace replacement in Indianapolis typically costs between $3,000 and $7,000 installed, depending on fuel type, efficiency rating, and home size. High-efficiency gas furnaces (96%+ AFUE) cost more upfront but can save $200–$400 per year on heating bills — a meaningful difference during Indiana winters.

HVAC systems should be professionally serviced twice a year — once in spring (AC tune-up) and once in fall (furnace tune-up). Regular maintenance extends equipment life by 5–10 years, improves efficiency by 15–25%, and catches small problems before they become expensive emergency repairs.

HVAC sizing depends on your home's square footage, insulation, window count, and layout. A typical Indianapolis home needs about 1 ton of cooling per 500–600 square feet. A qualified contractor will perform a Manual J load calculation to recommend the right size — oversized and undersized systems both cause problems.

The general rule of thumb: if your system is over 15 years old and the repair costs more than 50% of a new system, replacement is usually the better investment. New systems are 30–50% more efficient than models from 10–15 years ago, so the energy savings alone can offset much of the cost over time.
