VRF Tools
Free interactive tools built for the people who actually have to deal with commercial VRF systems and NYC compliance regulations. Each tool answers a specific question that comes up routinely in our service calls.
VRF Error Code Lookup
Enter an error code from any major VRF brand (Daikin VRV, Mitsubishi City Multi, LG Multi V, Fujitsu Airstage, Samsung DVM) and see what it means, what is likely causing it, and whether it warrants emergency dispatch. Built for building engineers and facility managers who get called at 2am with a fault display they don’t recognize.
NYC Compliance Checker
Tells you which Local Laws (97, 84, 87, 154) apply to your building based on size, type, and address. Useful for owners, asset managers, and consultants trying to plan compliance roadmaps without combing through the original ordinance text.
VRF Glossary
Sixty-plus commercial VRF, heat pump, and NYC compliance terms defined in plain language. Built for engineers who got handed a VRF system and are now figuring out the vocabulary.
