Preliminary research indicates that three of the most common uses of portable temperature control among businesses are construction, emergencies, and events.
- Portable heaters and air conditioners are popular on construction sites, which often do not have permanent heating or cooling until after the construction is finished.
- Temporary heating systems are also often necessary on construction sites to prevent frozen water pipes and to "maintain temperatures necessary for materials to set (such as adhesives)."
- Portable heaters are necessary on winter construction months to "keep materials (such as paint or putty) from freezing overnight, thaw the ground and allow concrete to cure, and — most importantly — keep... workers healthy and happy."
- Orion Building Corp. uses portable heaters during the winter months for their large scale construction projects.
- When building a new outdoor baseball stadium in Washington D.C., contractors used 34 commercial UCI heaters to provide temporary heat during construction.

- In February 2018, the Texas Department of Criminal Justice agreed to install temporary air conditioners during the summer months for prisons that routinely reach extreme temperatures. This was in response to a class action lawsuit settlement.
