Packaged Terminal Heat Pumps
2025-03-12 10:00 - 11:00
Join us as we discuss how upgrading packaged terminal air conditioners to high efficiency packaged terminal heat pumps (PTHPs) can revolutionize multi-family energy use. In this webinar we will dive into the advantages and disadvantages of PTHPs, their applications for both new construction and retrofits, and the growing size of this emerging market.

Heating and cooling systems are one of the biggest costs, and source of emissions, for multifamily properties. Join us as we discuss how upgrading packaged terminal air conditioners (PTACs) to high efficiency packaged terminal heat pumps (PTHPs) can revolutionize energy use in apartment buildings, hotels, and assisted living facilities. These self-contained units are installed below windows inside living spaces, providing efficient heating and cooling.
This webinar will explore the advantages and disadvantages of PTHPs, their applications for both new construction and retrofits, and the size of this emerging market. Learn how PTHPs, with advanced inverter technology and variable speed fans, provide the same in-unit temperature control and outside air as PTACs, while using up to 70% less energy. We’ll also discuss the quick and straightforward installation process, which makes PTHPs a compelling, cost-effective solution for property owners seeking to improve energy efficiency and tenant comfort. Finally, we’ll explore efforts to bring PTHPs to colder climates with models that can work in temperatures well below zero.
Please join us on Wednesday, March 12th to learn more about these simple high-efficiency units that can provide sizeable benefits.
