A well-maintained air conditioning unit makes your home more comfortable, and it prevents you from paying for frequent repairs. If you want to buy a new unit for your home, learn about the features of modern air conditioners. Use this guide to get more information about the new air conditioner regulations in 2020.

What Are the Regulations for New AC Units?

A new air conditioning unit uses a different type of refrigerant than older models. For years, hydrochlorofluorocarbon-22, also known as HFCF-22 or R-22, was the refrigerant used in residential ACs. However, this formula causes ozone damage, so the U.S. began phasing it out.

As of Jan. 1, 2020, HFCF-22 is no longer produced or imported into the country. Thanks to these new regulations, all modern air conditioning units will rely on another refrigerant that’s more eco-friendly.

How Do These Regulations Impact Older Units?

Aged units can still use R-22, but its supply is dwindling since it isn’t being produced or imported into the U.S. As a result, finding refrigerant for your old unit may be challenging, and when you eventually find it, it’s going to cost more.

How Do I Find an Energy-Efficient AC Unit?

Many modern air conditioners are designed for improved efficiency, which will reduce your energy costs and usage. Finding an energy-efficient unit is easy, thanks to standardized ratings. First, look for an Energy Star certification—this indicates that the unit optimizes efficiency without sacrificing functionality. Second, check the product’s SEER rating, which determines its cooling efficiency. The higher the SEER rating, the more efficient the unit, so look for a rating at 14.5 or higher.
