空调的风管系统具有以下特点：
（1）层高的问题比较突出一般中央空调使用在商场、电影院、写字楼等公共场所，这些地方的层高一般都比较高，因此层高的问题不是很明显，基本上都能满足中央空调风管系统安装、使用和维护的需要。但对于家用中央空调，由于它使用的地方很多时候层高低于3m，一般在2.8m左右，这就要求它配置的风管应尽可能少的占用层高空间。
（2）风管加工要求方便家用中央空调风管系统的加工量不大，但规格多，因此只能进行现场加工。由于家用中央空调风管的施工场地一般都比较小，且施工点比较多，因此不适合采用大型机器设备制作。另外，每户家用中央空调的风管安装位置都可能不同，不像写字楼、商场等，每层的布置基本固定，很多时候都需要进行现场定位，而且安装时还需要根据具体情况临时加工管道配件，如弯头、大小径等，因此要求风管的加工非常方便。
（3）对噪声的要求比较高家用中央空调主要使用在居住环境，因此对噪声的要求比较高。根据《中华人民共和国住宅设计规范》的要求，住宅卧室、起居室（厅）内的允许噪声昼间应小于或等于50分贝，而夜间应小于或等于40分贝[3]。风管机的机外余压一般为80~250Pa左右，噪音比较大，这就要求家用中央空调的风管系统加装有消声装置或自身具有较好的吸声功能。
（4）对风管强度的要求可适当降低中央空调使用的场合，如商场、办公楼等，经常可以遇到大空间，因此要求风管具有较高的强度。家用中央空调使用场合的跨度一般都比较小，通常都小于4m，这就使得对风管强度的要求可适当降低。另外，家用中央空调风管系统的通风量比较小，通风管道要求的口径也比较小，这也可以适当地降低对风管材料的强度要求。

水中央空调和其它空调形式一样，有着严格的安装规范，一般在安装水系统中央空调时，施工人员和现场工程师非常注重水的问题。空调漏水的最大隐患来自供水压力，如果水管或PPR管无法承受水压，极有可能出现漏水，因此，中央空调水系统管路安装工艺显得非常重要
