Few modern inventions are better than air conditioning, as there’s nothing worse than not being able to feel comfortable during the brutal summer heat. But figuring out which kind of air conditioning system that’s best for you can be complicated, as it turns out there are quite several different options depending on your needs.

Each kind of unit — whether it’s portable, wall-mounted, mini-split or a whole-home system — is going to have its pros and cons around power (BTUs), energy efficiency (SEER), and how well-suited it is to cool your individual square footage. We’ve rounded up the top three picks across each of those four categories with that in mind. Portable and wall-mounted units are easier to acquire. You can get them from most traditional retailers, but mini-split and whole-home units will require professional installation to make sure they’re set up and running effectively. 

Regardless of your cooling needs, there’s bound to be a solution to help you keep cool and carry on as the summer heat starts to roll around. Below, find all the helpful information you need to make you cool as a cucumber.

2. LG Mini Split Air Conditioner

LG is spearheading the way on ducted-based mini split air conditioners, which means the air conditioning unit is housed in existing ductwork close to the vent, which means the interior unit largely remains out of sight and out of mind. Depending on which route you want to go, LG’s units can be installed at greater heights and distances from the outdoor unit than other brands and are based on WiFi, which allows you to place them further apart from one another. The majority of the units are pretty stylish (insofar as you can be with these kinds of things) and come in a variety of different BTU powers.
