If you’re looking for a way to beat the summer heat and save on your electricity bill, an energy efficient home air conditioner is the way to go. But with so many options out there, it can be overwhelming to choose the best one for your home. Before making a purchase, there are a few factors to consider that will help you make an informed decision.

First, consider the size of the unit. A unit that is too small for your home will have to work harder to cool it down, using more energy and increasing your bill. On the other hand, a unit that is too big will cool your home too quickly, resulting in wasted energy and lower efficiency. It’s important to measure the square footage of your home and consult with an expert to determine the optimal size for your AC unit.

Another factor to consider is the unit’s SEER rating. SEER stands for Seasonal Energy Efficiency Ratio, and measures how efficiently the unit uses electricity. The higher the SEER rating, the more efficient the unit is, resulting in lower energy bills. The minimum SEER rating in the US is 13, but the most energy efficient units can have a SEER rating of 21 or higher.

Still not sure which energy efficient home air conditioner is right for you? Ask yourself some questions, such as: How often will you use it? What climate do you live in? What’s your budget? Taking these factors into account will help you narrow down your options and choose the best energy efficient home air conditioner for your needs.
