An increasingly popular type of air conditioner system available on the market is one that offers two-stage cooling, rather than the industry-standard one-stage A/C compressor. The two-stage system can operate at full speed, which is the single speed in a regular A/C, or a lower speed when outside temperatures don’t require full-on operation. This is the great majority of the time in the Twin Cities area, where our summers are relatively mild. Let’s examine the areas of improved efficiency that you can expect when investing in a two-stage cooling system.
Improved Efficiency
- The two-stage cooling system runs nearly continuously in the lower speed, resulting in improved and consistent comfort levels in your home. Standard A/C systems can produce fluctuations in the inside temperature of your home during the on-off cycle.
- Utilizing the lower-speed setting in the mornings, evenings and on mild summer days saves energy and therefore results in lower energy bills.
- The continuous operation of the system reduces wear and tear that results from the start-and-stop operation of a standard system, resulting in lower maintenance bills and a longer life cycle.
- Humidity control is improved in a two-stage air conditioning system because the coils are able to draw more moisture from the air during the continuous operation of the system. Air filtration is superior for the same reason.
You can save money when using a two-stage A/C because of the increased energy efficiency and the reduced maintenance costs associated with this type of air conditioning system. Investing in an annual preventive maintenance service performed by a qualified and professional HVAC contractor can further extend the service life of your two-stage cooling system and also reduce maintenance costs.
