Heating and Cooling Services for Johnson County Homeowners

Dugan Air covers everything Johnson County homeowners need to stay comfortable, from urgent repairs to full equipment replacements year-round.

Air Conditioning Repair, Maintenance & Replacement

Central Indiana summers bring sustained heat and humidity that put significant strain on aging or poorly maintained cooling units. Dugan Air provides comprehensive air conditioning services for Johnson County homeowners, including:

• AC repair: Refrigerant leaks, compressor failures, frozen coils, electrical faults, and airflow restrictions are all problems our technicians diagnose and resolve accurately across all major brands.
• AC maintenance: A thorough annual tune-up keeps your AC running at peak efficiency through the cooling season, reducing the likelihood of mid-summer breakdowns when demand is highest.
• AC installation & replacement: Free estimates for new central air and ductless mini-splits from Mitsubishi and American Standard, with proper load calculations to ensure your new unit is sized correctly for your home.
