One of the most important systems to consider when planning or managing a multifamily apartment building is the HVAC system. People have different preferences in terms of temperature control, and calibrating an HVAC solution that will keep everybody satisfied is critical. Developers and property managers have two primary options to choose from when it comes to cooling and heating installation: centralized and decentralized. Find out more about each choice below.

Centralized HVAC

A centralized HVAC system supports multiple units in a multifamily building. Four-pipe and geothermal systems are two popular types. A four-pipe system consists of two supply lines and two return lines, with one pipe in each pair for hot and cool water. The pipes run through air handlers, and the water inside them regulates the air temperature before it's pumped into the building. In contrast, a geothermal system uses heat transfer between the air and the ground to control the temperature, much like a heat pump.

Cooling and heating installation for centralized systems is more expensive. However, these systems are more efficient, which can save money in the long run. Due to the higher installation costs, centralized HVAC makes the most sense for larger multi-family properties, such as mid- and high-rises. When selecting the type of centralized HVAC system, note that geothermal systems cost more to install but are more efficient, cutting heating and cooling costs up to 70%. 

Decentralized HVAC

Decentralized HVAC systems allow each unit in a multifamily property to directly control heating and cooling. Packaged thermal air conditioners, PTCAs, and self-contained systems are two popular decentralized options. PTCAs are self-contained forced-air systems that are installed through a wall, with heat sinks and vents inside and outside. Self-contained systems deliver hot and cold air via independent units, each with its own heating and cooling mechanisms. The equipment can be installed on an exterior wall or in a closet.

Decentralized HVAC systems are more cost-efficient to install but less energy-efficient than centralized systems, making them an ideal solution for smaller multifamily buildings. Many renters prefer this option because it gives them direct control over heating and cooling within their personal space. Mini-split units allow for zoned heating and cooling, so people can control the temperature in different areas of their home according to their preference.
