Differences Between Centralized And Decentralized HVAC
Posted on: 29 November 2022Share
A centralized HVAC system cools or heats air at a central location and distributes it to other house parts. A decentralized HVAC has individual units in different parts of the house for independent heating and cooling. Below are some critical areas in which the two HVAC systems differ.
Space Utilization and Aesthetics
One of the best things about a centralized system is that you can create a dedicated place for it. Say you have a part of your house that you are unlikely to use. Alternatively, maybe you have space where you can create an additional room. You can install a centralized HVAC in that space and have it out of the way.
An out-of-the-way installation means the unit and its accessories don't have to interfere with your home's décor. Centralization also means you can maximize the uses of other parts of your house.
Consider two forms of efficiency when comparing centralized and decentralized HVAC systems. First, consider energy efficiency, where the decentralized system rules. With a decentralized system, you can customize your heating and cooling needs depending on each zone's needs. For example, you can heat and cool the upstairs rooms independently of the lower ones.
Secondly, a decentralized system also cools and heats your home more efficiently than a centralized system. Again, the reason is that decentralization allows each part of the HVAC to target independent heating and cooling to different parts of the house.
Your HVAC system will need regular maintenance and perhaps repair at some point. A decentralized system can be challenging to maintain and repair because the different parts of the system are scattered all over the building. Contrast this with a centralized HVAC where the contractor can easily work on the system because all its components are in the same place.
One of the best things about a decentralized system is that you don't lose service to the entire house if one part of the system malfunctions. For example, you can lose cooling in the kitchen and still enjoy the service in the bedroom. This situation is impossible with a centralized system where a system failure affects the whole building.
Centralized HVAC typically has higher initial costs than decentralized HVAC. For example, you need ductwork running to and from the HVAC unit irrespective of the house size and layout if you opt for a central system. The duct material and installation labor increase overall HVAC installation costs.
Whichever option you choose, get an experienced HVAC contractor for the installation. After that, use regular maintenance to care for the system, and it will serve you efficiently for a long time.
