The proper functioning of your air conditioner unit is central to ensure that your home has a comfortably cool indoor environment during the summers. However, the performance of an AC unit deteriorates over time. On average, an AC unit has a lifespan of 15 to 20 years. Even with such a lifespan, most AC units start losing in terms of efficiency from 10 years onwards. When the efficiency dips below a certain point or the unit needs expensive repairs too often, having the unit replaced is often a viable option.
When you are replacing an AC unit or getting a new unit for any other reason, it is important to make the right choice. This involves more than choosing the right company – you also need to consider a number of other factors to make sure that the unit you get is suitable, effective, and efficient. Here is a look at some of these factors.
Size and Capacity
The size or capacity of an AC unit is obviously a key consideration when purchasing one. You will need some guidance to determine the right size for a given space. In general, the larger a space is, the greater is the size or capacity you want. At the same time, the outdoor temperature conditions and the location of the room with respect to sunlight play a role as well. If the house has plenty of shady trees outside, you may need an AC unit with a lower capacity. In contrast, a unit with a greater capacity will be required if direct sunlight hits the target room.
SEER stands for Seasonal Energy Efficiency Ratio. The SEER rating is simply an indicator of the energy efficiency of an AC unit. The higher the SEER rating, the more energy-efficient the unit. Most modern units have SEER ratings between 13 and 21. When purchasing a new AC unit, you can use the SEER rating as a guide to choose energy-efficient models. The energy efficiency of a unit also translates into lower energy bills and possible tax rebates in the long run.
The evaporator coils of an air conditioner use a refrigerant which circulates through the coils and cools the indoor air. There are different types of refrigerants. Some, like R-22 which is also known as Freon, are being phased out due to its adverse impact on the environment. So availability is a major problem with R-22.
If you purchase an air conditioning unit with R-22 refrigerant, you will end up paying hefty amounts whenever you need a refrigerant top-up. You can avoid this by investigating a bit about refrigerants when purchasing an AC unit and ensuring that you get one that uses a more readily available type of refrigerant.
Stages of Operation
Some AC units come with a single-stage operation. This means that whenever you turn them off, they run at full power. Other units come with multi-stage operation. So when you require less amount of cooling, such a unit may run at lower power. Single-stage AC units typically consume more electricity and are less efficient compared to multi-stage units.
The noise produced by an air conditioner can range from negligible to significant. The noise for a given unit is typically measured in decibels, or db. You may want to consider the decibels of noise produced by a unit before you purchase it. If you end up buying a unit that is great in every other way but makes a lot of noise, your new unit can quickly become a hassle.
The actual price of an AC unit is naturally another important consideration when you are purchasing one. The size of the unit is directly proportional to its price. Also, a model is likely to have a higher price tag if it has a whole range of features. So you can expect multi-stage units to cost more than single-stage units.
