The seasonal energy efficiency ratio (SEER) is the ratio of the total heat removed from the conditioned space during the annual cooling season divided by the total electrical energy consumed by the air conditioner during the same season. So, the higher the SEER rating, the less electrical energy your air conditioner uses to cool your home. Purchasing an air conditioner with a higher SEER rating could be more expensive but save you more money on your electricity bill. (U.S. Department of energy)
To meet the new requirements of SEER2, all air conditioning and heat pumps even the ones that meet current SEER ratings must be renovated by January 1, 2023. In order to achieve this the units must cumply with the new M1 testing procedure. This test will increase systems' external static pressure to better reflect field conditions of the equipment. Why are the region where you live important ?
The U.S. Department of Energy (DOE) enforces SEER2 requirements according to your geographical region. Since people living in southern climates use their air conditioners more often, they require more energy efficient systems. In 2015 the department decided to consider this, and the nation was divided into two main regions (North and South) based on the population weighted number of heating degree days (HDD). States with 5,000 HDD or more are considered part of the northern region, while States with less than 5,000 HDD are considered part of the southern region. The Department of Energy further split the southern region into two regions: “Hot-dry” and “Hot-humid”. The table below shows the minimum SEER value for each region.
In addition to the regional standards DOE also adopted new efficiency standards for other types of central air conditioners, as well as heat pumps.
Why it is important to comply with these requirements?
A higher SEER2 rating will mean lower utility bills and more comfort this is because this units tend to come with features like multi-stage cooling making your residence or business more comfortable. New air conditioners might be more expensive, but the use of a more efficient model means you will save more on every utility bill.
The US Department of Energy predicts the new standard for furnace fans will:

When deciding which air conditioner is the best for you, there are many factors and features that must be taken into account to assess the quality of an air conditioner.
In this article we will give you the keys to know how to choose a good air conditioner that suits what you really need. Taking into account the surface to be cooled and the number of rooms that are going to have an air conditioner is decisive in choosing the right model.
However, almost all models also have a silence option, also called sleep, which consists of the air conditioning progressively reducing the power of the air and at the same time reducing noise, which drops to less than 20 dB. Turn it on during bedtime and you will enjoy a quiet night as well as a comfortable temperature.
Air conditioning equipment, as energy consuming devices, must display an energy label indicating its level of energy efficiency, with a rating in colors and letters from A++ for the most efficient to G for the most energy they consume. The energy rating is determined through the SEER. Since January 1, 2013, the SEER is used as a measure of the energy efficiency of an equipment and therefore it is this coefficient that determines a certain energy rating based on the range where it is located. This regulation establishes the eco-design requirements for air conditioners with a thermal input ≤ 12 kW. One of the novelties of this regulation was the energy rating of equipment based on seasonal energy efficiency, hence its name is Seasonal Energy Efficiency Rating (SEER). For their calculation, the following parameters are considered
This gives a more realistic measure of consumption and its efficiency. In fact, it is not true that the equipment works at 100% every day. The consumption of the equipment when it is turned off or on standby is also evaluated. This factor is also very relevant in real conditions and is often called phantom consumption.
SEER Equivalent Values Factors Influencing SEER Value
An air conditioner with 3 kW of thermal power with a SEER of 8.5 (A+++) will give us 0.35 kWh of consumed power in one hour. (3 kW / 8.5= 0.35 kWh) In AMPLUS AC we work only with equipment that meets SEER (Seasonal Energy Efficiency Ratio) energy efficiency requirements. The minimum standard SEER for air conditioners is 13, though most modern air conditioners have a SEER that ranges from 13 to 21. We work with brands as Trane which offers air conditioners range from 14.5 SEER up to 22 SEER
All air conditioners have a useful life and sooner or later they must be renewed, the important thing is to determine when the right time is. The end of its useful life will depend on the use you have given it, its maintenance, and the quality of the equipment you have installed.
Here we present some keys to determine if the change of your Air Conditioning is necessary Antiquity In general, the device has a useful life of around 15 years, however, after 10 or 12 years it may begin to show failures or high energy consumption. In the presence of the first errors is when its replacement or repair should be reconsidered. Inadequate Performance
Change in the surface of the cooling area In the specific case that the area in cubic meters that is wanted to be cooled, the change to a more powerful air conditioning unit would be necessary. Ecological Issue One of the reasons that may motivate people to change their current air conditioning equipment may be to replace it with one that complies with environmental care certifications. Noise Older air conditioning designs generally cause more noise while using it, with current technology it has been improved to reduce the noise almost completely, being another of the reasons for changing your air conditioning. In all these cases, it is recommended to replace the air conditioning with a new one, since poor operation also means a considerable increase in maintenance cost and electricity bill since the system needs more energy and, even so, it is less effective compared with a new device. In the case of the requirement of new characteristics or properties that only have air conditioners of the latest generation, the change is also the solution. If your final decision is to change your current Air Conditioner, here you have some useful tips:
