When it comes to installing an air conditioning system in your home, you really have two options: window air conditioning units or a central air conditioning system. But, how do you decide which is right for your home? The first place to start is by comparing how the two stack up in cooling capacity, efficiency and cost.
While cost and energy efficiency is key, it’s most important that the system will cool your home, right? For this purpose, central air conditioning systems are often the better choice because they cool more evenly. Programmable thermostats can be used to shut the unit off or adjust the temperature, which can save money and energy. However, window units also have an advantage because they allow you to control the cooling level in each individual room.
The efficiency of central air systems are measured in EER (energy efficiency ratio). In general, central air systems are rated higher, making them more efficient. To be ENERGY STAR certified, a window unit must only have an EER of 9.4-10.7, while a central air system must have a rating of at least 12.
Based on your budget, the biggest factor may be cost over cooling capacity. On average, window air conditioners are less expensive to buy and install than central air conditioners. While window units cost less, if you have a large home to cool, installing a central air system could be more cost effective than running units in several rooms.
Ultimately, the choice to install window units versus a central air conditioning system is based on your budget and cooling preferences. For questions, call the northern Virginia air conditioning repair and installation experts at EasternTech.
