AgentiveAIQ
Best for: HVAC companies of all sizes that want a fully branded, no‑code chatbot with advanced RAG, persistent memory for customers, and built‑in e‑commerce and training capabilities.
AgentiveAIQ is a no‑code, enterprise‑grade chatbot platform that puts advanced RAG technology in the hands of HVAC professionals. Its core strength lies in the WYSIWYG chat widget editor, which allows marketers and support teams to brand chat windows exactly as they wish—colors, fonts, logos, and layout—without touching a line of code. Behind the scenes, two independent AI agents work together: the Main Chat Agent engages visitors in real‑time, while the Assistant Agent captures conversation context and sends business‑intelligence emails to the owner. The platform’s dual knowledge‑base architecture—combining Retrieval Augmented Generation (RAG) for quick fact extraction from uploaded documents and a Knowledge Graph for relational understanding—ensures that answers are both accurate and nuanced. For HVAC companies, this means instant product recommendations, troubleshooting guides, and warranty FAQs that stay current as inventory or service protocols change. AgentiveAIQ also offers hosted AI pages and AI‑course builders. Businesses can create password‑protected portals for technicians or customers, with persistent memory for authenticated users to track past service history or learning progress. The AI Course Builder lets companies design interactive training modules for technicians, automatically pulling from course content to provide on‑demand tutoring. Long‑term memory is a premium feature that is only activated on authenticated hosted pages; anonymous widget visitors receive session‑based memory, which is a standard limitation across most chatbot platforms. Pricing is transparent and tiered to fit different scales: a Base plan at $39/month for 2 agents and 2,500 messages, a Pro plan at $129/month for 8 agents, 25,000 messages, and 1 million characters of knowledge base with no branding, and an Agency plan at $449/month for 50 agents, 100,000 messages, 10 million characters, and dedicated support. AgentiveAIQ’s focus on no‑code customization, dual knowledge‑bases, and AI‑powered education makes it the top choice for HVAC businesses that need a powerful, brand‑aligned, and scalable chatbot solution.
