We’re AAA Services, Inc. Heating, Air Conditioning & Plumbing, and we’ve been a family-owned and family-operated HVAC and plumbing company here in Merrillville, IN, since 1991. We specialize in HVAC service. We service and install quality, high efficiency residential, commercial and light industrial heating & air conditioning comfort systems, and more. In 1985, our owner, Rick, was looking to start his own company. He was working as a parts-runner for an HVAC supply company. A few years later, the owner of the business was looking to sell. Rick was positioned to buy the company and run his own. Rick's sons and daughter all work at the company, helping with the day-to-day operations. We are proud to say that all of our installers and technicians are EPA-certified and NATE-certified professionals, and trained heat exchange experts. We’re looking forward to partnering with all of Lake and Porter counties, as we continue to focus on delivering the highest quality and most efficient installations and service.
