Deciding on the right HVAC system means asking the right questions. Some HVAC systems are available as single split systems or multi-split systems. Both provide efficient solutions for commercial heating, but one might prove to be a better option for you depending on the size of building your heating, and how much control you want for your interior temperature zones, and how much space you have available.
Advantages of a Single Split HVAC System
A single split HVAC system is an excellent choice for smaller commercial buildings, especially those that would benefit from having the option of heating and cooling specific areas. An advantage of choosing a single split system is that you can create heating zones and efficiently regulate the temperature of your indoor environment depending on the specific usage. For example, you can keep storage areas cool to save on energy costs, and ensure private office spaces are warmer so that your employees and customers are always comfortable. You can regulate the temperature of all areas conveniently through one thermostat control panel. Another advantage is that each single split HVAC unit is self-contained so if you have any repair issues, only one region is likely to be affected. From an installation perspective, a single split system can be less expensive than installing a central multi-split HVAC unit. Single split systems do require a separate outdoor unit for each indoor unit that’s installed so they may not be practical for larger buildings.
Advantages of a Multi-Split HVAC System
Most of the benefits of a multi-split HVAC system are comparable to a single split option. You can determine the heating zones, and control the temperature of each with a central thermostat. The main difference is that while these HVAC systems use multiple units indoors, they connect to a single outdoor unit which is designed to operate at variable speeds. This saves energy because the compressor isn’t turning off and on throughout the day as it meets your heating and cooling demand. Instead, the built-in sensors detect the changes in temperature and make small adjustments for smooth and continuous operation. The extra ducting of a multi-split system makes installation cost a little higher, but if the outside of your building has limited space, having just one outdoor unit makes this a better option.
