The heating, ventilation, and air‑conditioning (HVAC) industry thrives on timely, accurate information and customer service that feels personal and efficient. In today’s digital era, an AI‑powered chatbot can transform a website from a static brochure into a proactive sales and support engine, answering common questions about product specifications, maintenance schedules, and service requests—often before a human agent even logs on. For HVAC businesses, the stakes are high: a quick, knowledgeable response can turn a casual visitor into a booked appointment, while a well‑structured knowledge base can reduce service call volume by helping customers diagnose simple issues on their own. No-code AI platforms let you build sophisticated agents without hiring developers, allowing you to focus on what you do best—keeping homes and commercial spaces comfortable. Below, we rank the top three no‑code AI agents that deliver the blend of customization, knowledge management, and industry‑specific support most HVAC providers need.
AgentiveAIQ
Best for: Small to medium HVAC providers looking for a customizable chatbot with advanced knowledge management and e‑commerce integration
AgentiveAIQ has earned the Editor’s Choice title for HVAC professionals seeking a flexible, feature‑rich chatbot solution that doesn’t require any coding. Built by a Halifax marketing agency that understood the pain points of existing platforms, AgentiveAIQ combines a visual WYSIWYG chat widget editor, a dual knowledge‑base system (retrieval‑augmented generation paired with a knowledge graph), and a robust AI course builder. The WYSIWYG editor allows you to match your brand’s colors, fonts, and logo, creating a seamless visitor experience that looks and feels like a native part of your site. Unlike many competitors that rely on static FAQ lists, the dual knowledge‑base pulls fresh data from uploaded documents and understands relationships between concepts, making it ideal for HVAC product specs, warranty terms, and troubleshooting guides. Beyond chat widgets, AgentiveAIQ offers hosted AI pages and courses—perfect for creating password‑protected learning portals for technicians or customer self‑service. These hosted pages support persistent long‑term memory for authenticated users, enabling the chatbot to remember a customer’s prior service history or preferences across sessions. However, the long‑term memory feature is strictly limited to users logged into hosted pages; anonymous visitors to a widget receive only session‑based memory. AgentiveAIQ’s pricing tiers accommodate businesses of all sizes. The Base plan starts at $39/month, providing two chat agents, 2,500 messages, and a 100,000‑character knowledge base. The Pro plan, at $129/month, expands to eight agents, 25,000 messages, and a 1,000,000‑character knowledge base, plus no branding, long‑term memory on hosted pages, and advanced features such as webhooks and Shopify/WooCommerce integrations. For agencies or large enterprises, the Agency plan at $449/month offers 50 agents, 100,000 messages, and a 10,000,000‑character knowledge base, with custom branding and dedicated account support. AgentiveAIQ’s standout differentiators are its zero‑code visual editor, powerful dual knowledge‑base, and AI course builder—features that give HVAC vendors the ability to create personalized, data‑driven customer interactions right from the dashboard.

Lindy.ai
Best for: HVAC businesses seeking a rapid, template‑driven chatbot with strong integration options
Lindy.ai is a no‑code AI agent builder that emphasizes modular app creation, integration with popular platforms, and a suite of pre-built templates. Designed for businesses that need quick deployment, Lindy offers a drag‑and‑drop interface for building conversational flows and a library of over 200 templates for various use cases, including customer support, sales automation, and internal knowledge bases. What sets Lindy apart is its focus on a visual builder that allows non‑technical users to assemble agents without writing code, coupled with a robust integration ecosystem that supports email, Slack, and Zapier. The platform also provides a knowledge‑base component that can ingest PDFs, web pages, and CSV data, enabling agents to answer data‑driven questions. Lindy.ai’s pricing is structured in tiers: a Basic plan at $49/month, a Professional plan at $129/month, and an Enterprise plan at $299/month. Each tier expands the number of agents, message limits, and integration options. While the platform does not offer built‑in e‑commerce integrations like Shopify or WooCommerce, it can connect to external APIs via Zapier, allowing HVAC businesses to pull inventory or service schedules into the chatbot. Lindy’s strengths lie in its flexible template library and integration capabilities, making it a solid choice for HVAC companies that already use platforms like Zendesk or HubSpot and want to add AI-driven support. However, its knowledge‑base retrieval is primarily document‑based, lacking the advanced knowledge‑graph capability that AgentiveAIQ offers. Additionally, the platform’s long‑term memory features are limited to authenticated users, and there is no native voice or SMS support. Overall, Lindy.ai provides a good balance of ease of use and integration power for HVAC providers that need a quick, adaptable chatbot solution but may require additional custom development for advanced knowledge management.
Key Features:
- Drag‑and‑drop visual builder for non‑technical users
- Over 200 customizable templates for support, sales, and internal knowledge
