Difference Between 14 SEER and 16 SEER (With Table)

Before buying something, it is better to know certain things about it. Some things don’t require that much care and maintenance, but some do. Electronic equipment does require a sufficient amount of care and for that, the person buying the appliance should know what will make the appliance last longer. When someone wants to buy an air conditioner, the first thing they should notice about it is the SEER rating.

14 SEER vs 16 SEER

The main difference between 14 SEER and 16 SEER is that 14 SEER models have single-stage compressors, while 16 SEER models have two-stage compressors. This impacts the efficiency and performance of the models immensely, and another main difference is that 16 SEER is more energy-efficient than 14 SEER. SEER stands for Seasonal Energy Efficiency Ratio and it determines, measures, and calculates the efficiency of air conditioners.

14 SEER vs 16 SEER

14 SEER was probably one of the oldest SEER models and nobody prefers using them nowadays because these models are some of the least efficient since the technology has developed a great deal since they were first created. 14 SEER models are used in areas where the climate is chilly or cold. After all, they cannot run for a long time without issues.

16 SEER is currently the most bought and preferred, because they have a two-stage compressor, and they are efficient every day. They are more environmentally friendly, cost-friendly, and certainly more energy efficient. Though 16 SEER costs more to install, it is worth it, because it reduces the humidity in the home to a great extent.

Comparison Table Between 14 SEER and 16 SEER

Parameters of Comparison14 SEER16 SEER
Comfort Level14 SEER models offer less level of comfort than 16 SEER models. 16 SEER models offer more comfort and if someone is looking for models that cool the house faster and offer more comfort, 16 SEER models will provide that.
Energy efficiencyAccording to data and information obtained, 14 SEER models use more units of energy than their successors like 16 SEER models. 16 SEER models use about 13 to 15% less amount of energy than 14 SEER models, but this can depend on many other factors.
Cost efficiency Using a 14 SEER costs more than using a 16 SEER model regularly, but the maintenance and installation cost is slow. While maintenance and installation costs are higher than 14 SEER models, the electricity bill is certainly lower when 16 SEER models are used.
Sound levels14 SEER models are noisier than most of the other models. 16 SEER models run much quieter than 14 SEER models.
PerformanceMost of the 14 SEER models are single-stage models.Some models of 16 SEER models are now built with two-stage air conditioners.

What is 14 SEER?

A person can buy 13 SEER and 14 SEER air conditioners if they want, but if they must run the air conditioner year-round and expect more efficiency, it is better to choose 16 SEER AC. When somebody resides in an area which is cold most of the time and they don’t switch on the air conditioner often, it is better to buy a SEER 14 model. When the budget is low or the energy efficiency of the house is low, SEER 14 will suit the criteria better. The maintenance and installation cost of 14 SEER models is low comparing the 16 SEER models.

Since most of the 14 SEER models have single-stage compressors, it can affect the temperature balance and dehumidification the model provides. In 14 SEER models, the humidity reduces very slow and gradually, and it takes longer for the cooling to spread throughout the house.

What is 16 SEER?

Nowadays, 16 SEER and 18 SEER are bought more, and what SEER air conditioner a person buys depends on where they live, their budget, and the overall climate in their area. 16 SEER must be maintained properly so that it can stay efficient for a long time and if the AC is going to run all day and one wants to save money, it is better to install 16 SEER. It contains many features that are not present in the old SEERs like 14 SEER.

When the air conditioner must be switched on constantly and keep running, it is wise to choose SEER 16 models and a lot of money can be saved. 16 SEER models reduce humidity in the house faster than 14 SEER models. 16 SEER models can also cool a large area of spaces faster than 14 SEER models and this impacts the performance of the AC.

Main Differences Between 14 SEER and 16 SEER

  1. There are few differences between, so when buying them, a person should decide which model suits their home and the overall climatic condition in their area.
  2. 16 SEER uses less energy than 14 SEER models. 14 SEER models consume about 15% more energy to run than 16 SEER models and this impacts the electricity bill a great deal.
  3. 16 SEER models have two-stage compressors, while most of the 14 SEER models have only single-stage compressors and this can change their performance.
  4. 16 SEER models adapt to the environment and the climatic conditions inside the house and run accordingly, while 14 SEER models do not, since they do not have a two-stage compressor.
  5. 16 SEER models run more quietly and they can run for long periods without making any noise or consuming more energy, but 14 SEER models cannot run for extended periods without any compromise.
  6. 16 SEER models are more cost-efficient, but both the SEER models are equally economically friendly.


It is always a tough decision to choose between 14 SEER and 16 SEER models since both the models have their advantages and disadvantages. It all depends on the amount of area that should be covered, the level of cooling required, the surrounding temperature, the size of the unit, and much more.

Every buyer and every home is different, so it is better to buy consult an HVAC for assistance and guidance in the entire matter of choosing, buying, and maintaining an air conditioner. They will help the buyers understand which SEER rating model suits their house or office better.
