Save money, improve air quality, and maintain your comfort with the right HVAC system.
Generally speaking, air conditioning units with a SEER rating of 16 or higher are considered highly efficient. SEER stands for Seasonal Energy Efficiency Ratio, which is the measure of a system’s cooling efficiency. Many premium quality air conditioning systems come with a capacity modulation feature, which allows you to adjust an air conditioner according to your requirements. This helps you save money on your energy bills, have more control over humidity levels, improve indoor air quality, and maintain a comfortable environment in your entire home throughout the year. However, not all modulating air conditioning systems work in the same way.
You will find mainly two types of modulating systems. One type features two stages of capacity, while another type comes with continuous or variable speed capacity. Before you choose, learn about the features and benefits of each type.
If you opt for a two-stage system, you will have mainly two capacity options. The system will use its full capacity during any hot and humid day in the summer, while it will use only 67 percent of its capacity during cooler days.
In comparison, with a variable speed system, you have more capacity options to utilize. If your indoor environment is already quite cool and comfortable, you can set the system to use only 20 percent of its capacity. Correspondingly, you can have the system to use higher capacity of up to 100 percent in a hot and humid day. This helps you avoid unnecessary use of energy. In the end, you save more on you energy bills. Two-stage systems usually come with a SEER rating of between 16 and 18, compared to a SEER rating of 25 or higher in variable speed systems.
The humidity levels in your home should not exceed 50 percent, says The Center for Disease Control and Prevention (CDC). Anything above 60 percent may encourage mold growth and make the indoor environment unhealthy. Controlling humidity levels could be more difficult than controlling the temperature, in most parts of the country. For instance, outdoor humidity levels in parts of the U.S. often range from 80 to 90 percent during the spring and fall months.
Two-stage systems have this capacity to operate longer than the conventional preset capacity systems, meaning that the former offers additional dehumidification. A variable speed system can offer additional benefits. This type of system runs the longest at a low speed and consumes less energy as well. A variable speed system may be your ideal choice in areas with high humidity levels.
Maintaining a Comfortable Environment
Variable speed air conditioning systems help release cool air more often, thus eliminates hot and cold spots, and helps maintain a cooler and more comfortable environment inside your home.
