A clean-cut man enters your house. He's wearing a pressed red shirt, crisp khaki pants, and red shoe covers on his feet. He places a small red mat onto the ground, preventing his tool bag from crimping or scuffing your carpet, hardwood floor, or indoor garden. He hails from Service Plus Heating and Air Conditioning, whose professional technicians travel throughout the greater Indianapolis area to diagnose and treat problems with plumbing and heating and cooling systems. Since starting the company in 2002 with just one service vehicle, Chris and Emily Cunningham have expanded their fleet to 14 trucks fully equipped to replace or repair virtually any HVAC unit, detect leaks or unclog faulty plumbing, or tune up almost any system. After scheduling an appointment online, customers receive a picture and brief bio of their assigned technician so they know exactly whom to expect.
