As the summer months approach, you may find yourself needing to replace an old or failing air conditioning system. When buying a new A/C unit, there are a number of factors to consider, such as power, efficiency, and reliability. As a licensed Bryant® installer, we wanted to compare the features of their new top-of-the-line Evolution® Series central air conditioning systems so that you can make an informed decision when choosing which model is best for your home’s needs.
The BRYANT Evolution Series Lineup
The Evolution Series represents Bryant’s top-of-the-line residential central air conditioning with units that range from single-stage to multi-stage cooling while maintaining quiet operation and extremely high energy efficiency.
As their flagship model, the Evolution 189B has a capacity range from 2-4 tons, extremely quiet 56db operation, a SEER rating of 19, and a 5-stage rotary compressor for variable cooling stages – all in a smaller footprint than any comparable model or anything else in the evolution line. The Evolution 180B, offered from 2-5 ton capacity, is a two-stage cooling unit that boasts and impressive SEER rating of up to 21 and quiet 66db operation. The Evolution 187B is also a 2-5 ton capacity, two-stage cooling unit with a SEER rating of 17 and 70db operation. The series is rounded out with the Evolution 186B, which is available in 1.5-5 ton capacities as a single-stage cooler with 68db operation and a SEER rating of 16.
All Evolution Series models are compatible with Bryant’s Evolution® Connex™ Control, which features a touchscreen LCD and Wi-Fi® controllability.
The SEER Rating System
The Seasonal Energy Efficiency Ratio (SEER) is a rating system devised to represent the efficiency of an air conditioning system. The SEER rating is calculated by dividing the cooling power, which is measured in British Thermal Units (BTUs) by the total energy consumed in watt-hours. In other words, the SEER rating indicates how much cooling can be achieved for a given amount of power. Therefore, a higher SEER rating indicates a more efficient system.
In 2005, the U.S. government instituted federal standards requiring all new systems to have a SEER rating of 13 or higher, though this baseline was updated in some states to a rating of 14 in 2015. An Energy Star® rating is awarded to units that have a SEER rating of 14.5 or higher.
Older units, which often have a SEER rating of 9 or even lower were grandfathered in under the newer federal guidelines. However, replacing one of these older units with a more modern, energy-efficient unit can bring substantial savings. For example, upgrading an older unit with a SEER rating of 9 to a new unit with a SEER rating of 13 would yield a 30% efficiency improvement – and a savings of about $300 a year. The Bryant Evolution Series have SEER ratings ranging from 16 to 21.
One-Stage, Two-Stage, and Multi-Stage Air Conditioning
An air conditioning system functions by circulating a coolant through different pressures to help control the temperature of the air flowing into the home. One-stage cooling units are essentially either on or off, while two stage units operate at a high or low level when on, depending on the need of the home. Multi-stage cooling units, like two-stage, have high and low level operation but with other grades between so that the work load on the compressor, condenser, and motors can stay more constant without heavy fluctuations. This has the benefit of ensuring more consistent air temperature while placing less stress on the system.
Think of it like riding a bike on flat ground as opposed to up and down hills. The flatter the surface, the easier it is to maintain a consistent speed without burning out. Similarly, multi-stage air conditioners can keep a constant temperature with greater efficiency and with less wear on the overall system.
So, Which BRYANT Evolution Series Central Air Conditioning Unit is Best for You?
All Bryant Evolution Series models are extremely energy efficient and will offer long-term savings over an older unit. The main distinguishing feature between each is the SEER rating and cooling operation. Though the 180B offers the highest SEER rating of the series, the 189B’s variable cooling system is both quieter and likely to offer the most consistent comfort with fewer temperature fluctuations throughout the day – which translates to less overall work and more long-term savings. It also has the smallest footprint, making it a potentially easier install for some space-limited designs, however it is only currently available up to a 4-ton capacity (though this is more than enough cooling capacity for most homes). The 180B, as stated, has a 21 SEER rating and has a 5-ton capacity option for the largest of homes. The 187B offers a large capacity and a strong SEER rating with quiet 2-stage operation, while being a little more budget-friendly than the 180B or 189B. The 186B, offering single-stage operation, represents the most budget-conscious option while still maintaining an above-average SEER rating and quiet operation.
