Hotwinter Company was originally established by a group of Fluid Mechanical Engineering students in 1978. The company’s activities covered everything from design to implementation to maintenance of Air Conditioning for buildings and various industries. Our customers were, among others: The Tehran County Ministry, the local Telecom Company, Hepco Industries and the Iranian TV Channel.


Because of our outstanding performance and state of art services, the company became the official wholeseller of the Iran Sarma Afarin Industrial CO. (former Carrier Thermofrig) in both Tehran and Hormozgan, in 1994. Iran Sarma Afarin Industrial CO. is the market leader of Iran’s Air Conditioning industry.

After our excellent reputation had spread all over Iran, we were able to expand our services to customers, both private and state owned, in every part of the country, only a few years later.


Today our services cover all aspects, from design, the choice of appropriate equipment, sales negotiations, installation, maintenance and after sales services (guarantee services).
