Single Stage vs Multi Stage HVAC
Many people are not even aware that there are two different styles of HVAC units for the home. If you’re a homeowner, you will definitely have a heating/cooling system installed in your home, but depending on your HVAC equipment, it may be either a single-stage or multi-stage system. So which one is best for your home?At the most basic level, single-stage HVAC systems only work in one setting. A single-stage HVAC system has only one stage of heating or cooling output. They are either running at full capacity (ON state) or not running at all (OFF state). Single-stage systems are best described as “on-off“.
A multi-stage HVAC system has more than one stage of heating/cooling output. The most common multi-stage system is a Two-stage heating/cooling system – which has two output levels of heating/cooling. A three-stage heating system, for example, means that you get a high, medium, and low setting to choose from, and the same goes for cooling.
How do I pick?
This decision ultimately depends on a few things: your budget and where you live. If you live in an area that has a humid climate with extremely hot summers, a two-stage system makes more sense. On the other hand, if your budget is restricted, a single-stage HVAC unit is the better choice.
