Air Conditioner Buying Guide: Key Factors To Look For

Buying an air conditioner (AC) is a significant investment, whether for your home, office, or industrial space. It is important to remember these features so you end up making a purchase that is suitable for you. So read on to know what are the key features to keep an eye on when Buying your next air conditioner.

1. Determine Your Cooling Needs:

Begin by assessing the size of the space you need to cool. The cooling capacity of an AC is measured in British Thermal Units (BTUs). To understand how to go about calculating we’ve provided a basic calculation method for estimation; an AC needs about 20 BTUs per square foot of living space.

For instance, a 500-square-foot room would require a 10,000 BTU unit. Oversized ACs can cool the air too quickly without removing enough humidity, leading to a damp and uncomfortable environment. On the contrary, an undersized unit will struggle to cool the space, running continuously and driving up energy costs.

2. Energy Efficiency:

Energy efficiency is crucial for long-term cost savings and environmental impact. Air conditioners with a high Energy Efficiency Ratio (EER) or Seasonal Energy Efficiency Ratio (SEER) which yields a higher rating means a more efficient unit. Modern ACs often come with Energy Star certification, indicating they meet or exceed US government standards for energy efficiency. Additionally, coolers with inverter technology, which adjusts the compressor speed to maintain the desired temperature that reduces energy consumption are desired.

3. Noise Levels:

ACs can be noisy, especially in quiet residential settings. Noise levels are measured in decibels (dB). A unit with a noise level between 50-60 dB is considered quiet. For bedrooms or study areas, aim for a lower noise level to ensure comfort and peace.

4. Features And Controls:

Modern ACs offer a range of features to enhance comfort and convenience. Air conditioners that have programmable thermostats, sleep modes, and energy-saving settings. Smart ACs with Wi-Fi connectivity allow you to control the unit remotely via a smartphone app are sought-after features. Additionally, advanced filtration systems can improve indoor air quality by removing dust, allergens, and pollutants.

5. Installation And Maintenance:

Consider the installation requirements for each AC category. For example, window coolers are relatively easy to install but can obstruct the view and light. Split systems require professional installation but offer a more aesthetically pleasing and permanent solution. Regular maintenance, such as cleaning or replacing filters, is essential to ensure the unit operates efficiently and has a long lifespan.

One common mistake most do is neglecting to check the voltage requirements of the AC unit. Some require a higher voltage outlet, and failing to provide this can lead to electrical issues or even damage to the unit. Another mistake is overlooking the importance of proper installation. Improper installation can result in reduced efficiency and increased wear and tear on the unit. Lastly, avoid the temptation to buy the cheapest unit available without thinking about long-term operating costs. A higher initial investment in an energy-efficient unit can save you significantly on energy bills over time.
