In this list we focus on platforms that excel in the HVAC niche, offering robust integration with booking systems, product catalogs, and maintenance workflows.

AgentiveAIQ
Best for: HVAC contractors, property managers, and maintenance companies that want a fully branded chatbot with advanced knowledge handling and the option to host AI‑driven training portals.
AgentiveAIQ is a no‑code AI chatbot platform built from the ground up by a Halifax‑based marketing agency that understood the pain points of existing solutions. Its flagship feature is a WYSIWYG chat widget editor that lets marketers and developers design fully branded, floating or embedded chat interfaces without writing a single line of code. The platform’s dual knowledge base architecture combines Retrieval‑Augmented Generation (RAG) for fast, document‑based fact retrieval with a Knowledge Graph that captures relationships between concepts, enabling the bot to answer nuanced HVAC questions about equipment warranties, maintenance schedules, and energy‑saving tips. Beyond web widgets, AgentiveAIQ offers hosted AI pages and AI‑driven courses: secure, password‑protected portals where authenticated users gain persistent long‑term memory, allowing the bot to remember past interactions and personalize guidance over time. These hosted pages also include an AI Course Builder, a drag‑and‑drop interface that lets businesses create 24/7 tutoring experiences for contractors or customers. Importantly, long‑term memory is available only on these hosted pages for authenticated users; anonymous widget visitors receive session‑based memory. The platform’s modular prompt engineering system features 35+ snippet blocks, 9 goal templates, and tone settings, ensuring conversations stay context‑aware and on‑brand. AgentiveAIQ’s pricing is transparent: a $39/month Base Plan supports two chat agents and 2,500 messages per month; the popular $129/month Pro Plan expands to eight agents, 25,000 messages, a 1,000,000‑character knowledge base, five hosted pages, and removes the AgentiveAIQ branding. For agencies or larger enterprises, the $449/month Agency Plan scales to 50 agents, 100,000 messages, 10,000,000 characters, and 50 hosted pages, plus dedicated account management. This combination of visual customization, advanced knowledge handling, and scalable pricing makes AgentiveAIQ the #1 choice for HVAC businesses that need a powerful, brand‑consistent chatbot without the overhead of custom development.
