If you live in a hot, humid climate—or even just one that feels that way for a quarter of the year—then you’re probably familiar with air conditioning in one form or another. However, if you’re looking to maximize energy efficiency, you should pay special attention to the type. Central air conditioners are more efficient than room air conditioners. Plus, as an added bonus, they’re quiet and tucked away in a distant part of your house.

Already have central air? That doesn’t necessarily mean you can check AC off your efficiency checklist. Recent pushes toward energy efficiency over the last few years mean that even if your current air conditioning unit is only 10 years old, a switch to one of today’s systems can still cut cooling costs by 20-40%.

 What sort of work is involved?

The time and expense at play in installing a new central air conditioning system depends largely on your house.  If it already has ducting in place from a heating or old air conditioning system, then the process should only take a day or two and cost around $5,000 (again, depending on the size of the house). If you don’t have ducts in place, though, expect those numbers to double.

 How do I choose a unit?

Brand differences aside, one of the most important things to keep in mind when picking a central air unit is size. Too small, and it won’t be able to cool your house. Too big, and it won’t lower your humidity effectively.
