What AC Heating, tepelná čerpadla - chytré řešení pro Váš dům does

AC Heating is a Czech designer and manufacturer of air-to-water heat pumps serving residential, multi-family, municipal, and commercial building customers since 2006. Founded by Michal Fiala and Lubomír Kuchynka and operating under the legal entity KUFI INT, s.r.o., the company manufactures its Convert NG MINI, Convert NG One, and Convert AW product lines at its facility in Letkov near Plzeň, complemented by its proprietary xCC (xCascade Control) smart regulation system developed in-house since 2009. The xCC platform integrates weather-based predictive control (PREDICTherma), spot electricity price optimization, FVE (photovoltaic) inverter communication, and remote diagnostics via the AC Connectivity service. Since 2022 the portfolio has been extended to photovoltaic (FVE) installations, enabling combined heat pump and solar offerings for customer energy independence.

The business operates on multiple revenue streams: one-time equipment sale and installation of heat pumps and FVE systems; 7-year full warranty and post-warranty service; free subsidy-application support (NZÚ, Kotlíková dotace, Čistá energie Praha); and a regulated 'Teplo jako služba' (Heat as a Service) managed-services model where the company designs, builds, finances, and operates heat-pump boiler rooms on multi-family and municipal sites, charging customers only for consumed heat under multi-year contracts. Go-to-market is sales-led with dedicated field sales representatives segmented by customer type (family homes, apartment buildings, heat supply contracts), supported by a B2B partner portal, a Plzeň showroom, and active presence at trade events (For Arch, Dny malých obcí) and digital marketing channels (SEO, Facebook, Instagram, YouTube, referral program).

Across roughly 120 employees, AC Heating has completed 12,248+ household installations and 241+ multi-family building projects in the Czech Republic, with historical exports to Slovakia, Germany, Belgium, England, and Ireland. The company holds a 4.9/5 Google rating and 98% Refsite recommendation rate, and its Convert NG One received the Red Dot Award 2025 and German Design Award 2025. The company is privately held, self-funded with no disclosed external investment rounds, and operates exclusively as a Czech-registered entity.
