Daikin-TMi

What Daikin-TMi does

Daikin-TMi is a privately held regional HVAC distributor and service provider headquartered in Chesterfield, Missouri, operating across Missouri, Kansas, and Illinois since 1966. The company distributes Daikin-branded commercial and residential HVAC equipment (including VRV variable refrigerant volume systems, ductless systems, inverter heat pumps, and Daikin FIT all-electric systems) to a network of HVAC contractors, dealers, and building owners, supported by an OEM and aftermarket parts division operating under the ASG sub-brand.

The company is organized into five operational divisions — Residential, Commercial, Parts, Controls, and Service — with more than 75 factory-trained technicians providing 24/7 emergency repair and maintenance coverage. Daikin-TMi also sells open-architecture building controls and integrated smart-building systems (energy dashboards, HVAC automation, security, lighting, toxic gas monitoring) that are positioned against vendor-locked competitors, and operates physical training centers in St. Louis and Kansas City alongside a mobile Daikin Roadshow Trailer for field contractor education.

Revenue is generated through four primary streams: HVAC equipment distribution (hardware sales), OEM and aftermarket parts/hardware sales, professional service and maintenance contracts, and managed building-controls solutions. Go-to-market is B2B channel-driven, combining direct field sales with territory managers serving a dealer/contractor network and direct enterprise accounts. Pricing is quote-based and negotiated; no public pricing tiers are disclosed. The company has 101–250 employees across five physical locations (Chesterfield HQ, Dardenne Prairie warehouse, Chesterfield ASG warehouse, Lenexa KS, Wichita KS). No funding rounds, M&A activity, ownership changes, or public leadership disclosures appear in the source material.
