If you’re considering replacing your central AC unit, the terms single-stage, two-stage and variable-speed are going to come up in your online searches and conversations with contractors. To make the right decision about which central air conditioner is right for you, it’s important to understand how each of these options will impact your comfort and budget.
All of these terms refer to the speeds – or speed, in one case – at which a central air conditioning system’s compressor can operate.
A single-stage central AC system is either on – full blast – or off. There’s no in between. This results in wasted energy and money. Imagine you’re driving, and your only means of maintaining the speed limit is to floor it or take your foot off the gas pedal. That’s single-stage technology.
This is not to say a single-stage system is never the right choice. It is the least expensive type of central air conditioning system to purchase, so if upfront cost is a more important factor to you than long-term operating costs and performance, it may be the right solution. However, if energy- and cost-efficiency are important to you, a two- or variable-speed unit is likely a better fit.
A single-stage system cycles on and off more frequently, while a two- or variable-speed central AC unit runs for longer at lower speeds – cycling on and off much less often. In addition to the energy and cost savings discussed above, this offers important advantages:
