do window ac units use freon?
308573
Window air conditioning units are used by many to cool apartments, homes, RVs and offices. These units use freon to create cool air. The freon is sent through a sealed tube, and should not run out. However, units get old and can develop leaks.

Cars used to use Freon as a refrigerant, but it's no longer allowed to be made in the U.S., so modern cars use R-134 instead. Most vehicles don't need refrigerant to be added more than every few years unless there's a leak somewhere in the system.

Freon is a gas that's used for cooling. When used in a freezer, it keeps your food cold and the overall temperature below freezing. ... Most modern refrigerators don't use freon anymore. Instead, they use a refrigerant called HFC-134a (1,1,1,2-tetrafluoroethane).

Fan Motor. Window air conditioners normally use a double shaft fan motor with two separate blades attached. One blade is used for drawing air over the cold evaporator coil and re-circulating it into the room.

The good news is that new air conditioning systems made since 2010 no longer rely on Freon. Most newer AC units use a refrigerant called R410A, or Puron. This chemical is an HFC (hydrofluorocarbon), but has been shown not to harm the ozone and, since 2015, has become the standard for residential air conditioning.

Energy Usage A window AC unit can use anywhere from 500 to 1440 watts of electricity to run, while a typical central air unit in the average sized home uses about 3500 watts.

For decades, Freon, also known as HCFC-22 and R-22, was the main refrigerant chemical used in residential air conditioning units and heat pumps. To help protect the ozone layer, the EPA has mandated that the production of Freon be stopped by January 2020. ... Most newer AC units use a refrigerant called R410A, or Puron.

It's generally less efficient. Portable air conditioners often take more BTUs — and therefore use more electricity — to cool the same square foot space as a window unit. This is likely because they generate waste heat indoors instead of outside, creating more overall heat for the unit to deal with.

Air conditioners have circulation systems designed to project cool air away from the units while refrigeration units have circulation systems designed to retain coolant in a confined space. Refrigeration systems circulate cool liquids and gases through a series of tubes and vents.

But rough estimates for how many watts an air conditioners uses are; Central Air Conditioner – 3500 Watts. Central A/C Fan Only – Compressor Off – 750 Watts. Largest Window Units – 1440 Watts.

You'll need to pick a place to vent your air conditioner – you can use an exterior wall, the garage door, or small glass windows. ... With a properly installed vent, the hot air can travel directly from the unit, through the vent and out of the garage.

A window unit AC uses 500 to 1440 watts, while a 2.5-ton central system uses about 3500 watts. That's a lot of power. A floor fan uses only 100 watts on the highest speed, and ceiling fans use only 15 to 90 watts depending on speed and size.

Window AC units are tucked away in a window, making them less noticeable and freeing up morel living space. They also use energy more efficiently, so you can get more cooling power per BTU. The higher the number of BTUs, the bigger the room it can cool.

So how much does freon cost per pound for central air (20)? Air conditioner freon refill cost can run $80-$140 per lb, and about $200-$500 for a whole unit to be recharged.

Freon-based HVAC units that still function properly don't need to be replaced now either. Beginning in 2020, Freon will no longer be produced or imported, but limited amounts will still be available. Older systems can be serviced or recharged with refrigerant using stocks of HCFC-22 until the 2020 date.
