Traditional air conditioning units are now becoming a thing of the past. With air conditioning units that are more energy-efficient and easier to maintain, it's no wonder why homeowners are making the switch to modern air conditioners.

Here are answers to some frequently asked questions about modern air conditioning systems to shed more light if you're considering making a switch:

How Many Types of Modern AC Units Are There?

Modern AC units consist of central air conditioners, ductless air conditioners, and geothermal heat pumps.

A central air conditioner is a system that uses air ducts to distribute cooled air throughout your home. The air is cooled by a refrigerant, with a fan that helps circulate the air. Central AC units are usually more expensive to install but are also quite energy-efficient.

A ductless air conditioner (also known as a mini-split air conditioner) is a system that doesn't require air ducts. The air is cooled by a refrigerant and circulated with a fan, but the air isn't distributed throughout your home –– instead, it's circulated in one specific area. Ductless units take up less space and are easier to install.

A geothermal heat pump is a system that uses the earth's natural heat to warm your home in the winter and cool it in the summer. These systems are very energy-efficient, but they're also quite an investment since they require special equipment to be installed.

How Do Modern AC Units Differ from Traditional Ones?

The main difference between modern and traditional air conditioners mainly has to do with refrigerant. Conventional air conditioners use refrigerants with chlorofluorocarbons (CFCs), which are harmful to the environment. When CFCs are released into the air, they contribute to the depletion of the ozone layer.

Modern air conditioners use hydrofluorocarbon (HFC) refrigerant, which doesn't damage the ozone layer. HFCs are also quite efficient, so your air conditioner will use less energy and save you money on your energy bills.

Another difference between modern and traditional air conditioners is the size. Traditional air conditioners are usually much larger than modern ones, so they take up more space inside your home.

Modern air conditioners are smaller and more compact (like ductless systems), which makes them more aesthetically pleasing and easier to install. They also have a lower carbon footprint, which makes them more eco-friendly.

Modern AC units are also equipped with HEPA air filters, which can remove up to 99.97 percent of air contaminants. These air filters are great for people with allergies or asthma, as they can help to improve the air quality inside your home.

If you want to switch to a modern air conditioning system but aren't sure which one is right for you, be sure to speak to a residential air conditioning contractor. They'll be able to assess your needs and recommend the best air conditioner for your home.
