Hydro-Temp

What Hydro-Temp does

Hydro-Temp Corporation is a U.S. manufacturer of geothermal and water-source heat pump systems founded in 1975 by Mike Jones in Pocahontas, Arkansas, with a current headcount of 11-50 employees. The company designs and builds residential and commercial HVAC equipment spanning 0.5 to 250 tons capacity, including the VStar variable-capacity series, 3Star multi-stage series, single-speed entry-level units, large commercial VSX and Tandem systems (up to 60 tons), H.O.T. high-output water-to-water units, Corner Console classroom products, and DOAS/MAU outside-air systems. Hydro-Temp holds U.S. Patent # 4,249,390 (issued 1981) for a full condensing on-demand hot water recovery unit that recovers waste heat from cooling operations to generate domestic hot water, and it was an early mover in integrated zoning, multi-stage, and variable-speed geothermal technology, earning ENERGY STAR Most Efficient recognition for four consecutive years (2013-2016) on the VStar Series.

The company generates revenue primarily through hardware sales of geothermal and water-source heat pumps distributed via a U.S.-wide certified dealer and distributor network, supplemented by direct engagement on design-build custom solutions for unique commercial, healthcare, and education applications. Hydro-Temp serves residential, commercial, education (including Net-Zero and Net-Zero Ready school projects), healthcare, and outside-air customer segments, with documented installations at Methodist Olive Branch Hospital, Kosair Children's Medical Center, Richardsville Elementary (the first Net-Zero public school in the U.S.), Marion Junior High, the University of Louisville, and the Colorado State Capitol. The go-to-market combines dealer-channel sales, direct design-build contracting, partnerships with electric cooperatives and utility incentive programs, and outreach through industry publications such as ASHRAE and High Performing Buildings Magazine. Sister company Air-Flo Company provides licensed mechanical contracting services in Arkansas, Missouri, Tennessee, Mississippi, and Alabama, complementing manufacturing with installation capability. The company has remained founder-aligned and privately held through 2024, when it secured $10,850,000 in funding from the U.S. Department of Energy.
