Air Conditioning Tip from AC Express

2-speed AC Unit

Buying a Two-Speed Cooling System for Your Home

Single-stage air conditioners

A single-stage air conditioner is like most light switches – it is either all the way on or all the way off. Single-stage air conditioners turn on 100% when the temperature in your home is warmer than your thermostat’s setting and turn off completely once that setting has been reached.

Two-stage air conditioners

Two-stage air conditioners are more like your typical ceiling fan – they can be completely off, all the way on, or at a medium speed. This is where two-stage air conditioners get their name; they have two speeds (or stages). If your home is extremely warm, a two-stage air conditioner will use the higher speed, but if only a little cooling is needed it will use a more energy-efficient lower speed.

One large difference for Austin residents to consider is Energy Efficiency. While any air conditioner you choose will likely be much more efficient than your old air conditioner, there is a significant difference in energy efficiency between single-stage and two-stage air conditioners.

Two-stage air conditioners, use a lower setting so they run longer and more consistently. A two-stage air conditioner will actually run longer than a single-stage, but use less energy because it is at a lower speed.

We understand that price is an important consideration when replacing your air conditioner, but it should not be the only one. Speak with a knowledgeable AC Express technician and find out if the two-stage model could save you enough money on your energy bills to make the price difference worth it.
