If you’re seeking to buy an air conditioner, you’ll notice that they all have a SEER rating. Before making a purchase, it is critical to evaluate the SEER (Seasonal Energy Efficiency Ratio). However, not every customer understands why. Continue reading to learn more about what a SEER rating is and why it matters for your air conditioning system.
What’s a SEER Rating?
The SEER of an air conditioner (or air-source heat pump) is calculated by dividing the unit’s overall cooling output over a season by the total amount of energy consumed. Because air conditioners aren’t constantly running at full capacity, the SEER rating is simply a snapshot of how efficient a certain unit is on average.
The SEER of air conditioners that use less energy while yet providing excellent cooling will be greater. In general, the greater the SEER rating, the more energy-efficient and potentially cost-effective the unit.
When searching for a new AC system, the standardized SEER rating system makes it especially simple to compare different systems. Rather than reading the fine print or relying on manufacturer promises, simply compare the SEER ratings to determine which units are the most efficient.
SEER ratings, on the other hand, simply attest to a unit’s efficiency. They do not consider durability or other aspects. It is critical to do regular maintenance on any AC unit to ensure that it performs properly.
Benefits of a High Seer Ratio or Rating
1. Higher Energy Efficiency
In some conditions, a higher SEER rating gives greater energy efficiency. The minimum SEER for air conditioners is 13, though most current air conditioners have a SEER ranging from 13 to 21. Trane air conditioners are available in SEER ratings ranging from 14.5 to 22. But keep in mind that this is a maximum rating. The efficiency of your system will vary depending on the size of your home, the state of your ductwork, and other factors. Even if your air conditioner has a high SEER rating, it’s still a good idea to adopt additional energy-saving tips during the summer.
The United States Department of Energy imposes minimum SEER requirements that vary by geographical region. The Southwest and Southeast have a minimum of 14, whereas the North has a minimum of 13. A SEER rating of 13 or 14 does not always imply that a unit is inefficient. Most older air conditioning systems have SEER ratings of 8 or 9, so even the lowest available SEER rated system you buy today will be substantially more energy-efficient.
2. Greater Indoor Comfort
Having a higher SEER air conditioning system means you’ll be more comfortable in the summer, especially if you reside in a hot location like the Southeast or Southwest.
Higher SEER systems frequently have two components that improve indoor comfort:
- 2-stage or variable-speed compressor
- Variable-speed blower
Lower SEER air conditioners are often single-stage and only have one speed. This implies that they will frequently turn on and off during mild weather, resulting in uneven cooling or hot and cold regions. You’ll also notice greater humidity levels, making it feel hotter than it is. To eliminate humidity from the air in your home, your A/C must operate for an extended length of time. A single-stage system’s ups and downs do not account for this.
What Is a Good SEER Rating?
There is no such thing as a magic SEER number. Anything over 13 is great. Because replacing an aging 8 SEER system with a 16 SEER unit will considerably cut the cost of cooling your home.
Don’t forget to look into tax benefits and manufacturer rebates, which can help you save money on a high SEER system. You can also feel good about consuming fewer fossil fuels, which means emitting fewer greenhouse gases.
