8 Myths About R-410A Refrigerant - Part One

There are a lot of misconceptions about R-410A Refrigerant. We're here to dispel the confusion!

We'll be breaking this information into two posts. Here are Myths 1-4!

Myth 1: The higher pressures of R-410A are unsafe.

Actually, air-conditioners that use R-410A are specially designed for the higher pressures of R-410A. These systems have typically been rigorously tested by their manufacturers, as well as by independent safety testing laboratories such as Underwriters Laboratories.

Many dealers of air-conditioning equipment are not educated on the benefits of this new refrigerant, and some use the “high pressure” argument to convince consumers not to buy a product which the dealer isn’t properly trained to install or service anyway.

With over a million R-410A based air conditioners operating worldwide, and nearly a decade of field testing and product history, there is no evidence to suggest that R-22 systems are any safer than systems that contain R-410A.

Myth 2: The higher pressures of R-410A cause air conditioners to break down more often.

Evidence shows this is not only untrue, but that R-410A air conditioners can be remarkably more reliable than air-conditioners that use R-22.

First, air-conditioners that use R-410A are designed to be heavier-duty, with a thicker compressor shell. Usually this results in smaller, sturdier pieces of equipment that vibrate less, putting less strain on the piping connections that are the source of most leaks.

Second, most air-conditioner manufacturers require their technicians to be fully trained on R-410A before they can sell or service that manufacturer’s R-410A equipment. As a result, the dealers and technicians that offer and install R-410A are often better trained and have the right tools to give you a more reliable installation.

One major air conditioner manufacturer who has been selling air conditioners for over 50 years tells us that their R-410A air conditioners and heat pumps are the most reliable systems they’ve ever introduced!

Myth 3: R-22 will remain cheap and available.

This is wishful thinking on the part of many service technicians. R-22 is being phased out globally, and the manufacturing plants that make R-22 in Europe, North America and other regions will eventually be shut down or converted to make other chemicals.

In 2003, the U.S. EPA implemented an allocation program which limits both the companies who can make and import R-22, and the amounts that they each can make or import. This essentially “capped” the supply of R-22 in the U.S.

The EPA has laid out the below schedule for phasing out HCFCs including R-22:

• January 1, 2004: The Montreal Protocol required the U.S. to reduce its consumption of HCFCs by 35% below the U.S. baseline cap.
• As of January 1, 2003, EPA banned production and import of HCFC-141b, the most ozone-destructive HCFC. This action allowed the United States to meet its obligations under the Montreal Protocol. EPA was able to issue 100% of company baseline allowances for production and import of HCFC-22 and HCFC-142b.
• January 1, 2010: The Montreal Protocol requires the U.S. to reduce its consumption of HCFCs by 75% below the U.S. baseline. Allowance holders may only produce or import HCFC-22 to service existing equipment. Virgin R-22 may not be used in new equipment. As a result, heating, ventilation and air-conditioning (HVAC) system manufacturers may not produce new air conditioners and heat pumps containing R-22.
• January 1, 2015: The Montreal Protocol requires the U.S. to reduce its consumption of HCFCs by 90% below the U.S. baseline.
• January 1, 2020: The Montreal Protocol requires the U.S. to reduce its consumption of HCFCs by 99.5% below the U.S. baseline. Refrigerant that has been recovered and recycled/reclaimed will be allowed beyond 2020 to service existing systems, but chemical manufacturers will no longer be able to produce R-22 to service existing air conditioners and heat pumps.

Myth 4: R-410A isn't the final refrigerant, and other new refrigerants are coming.

Every major air conditioner manufacturer in the United States has selected R-410A as its choice to replace R-22 in new equipment, and there are at least a dozen brands of R-410A air conditioners or heat pumps available today, with more coming soon.

Why? In less than 3 years the U.S. Department of Energy will require a 20% increase in the minimum efficiency of new home central air conditioners. This means that air conditioner manufacturers will have to find ways to increase the efficiency of their air conditioners. One easy way is to use a more efficient refrigerant, and because the refrigerant 410A is at least 5% more efficient than R-22, manufacturers can use R-410A to help them meet these energy efficiency goals.

In other countries like Japan where the phase-out of R-22 is further along than in the U.S. and Canada, the refrigerant R-410A is used extensively. The United States is expected to follow their lead, allowing R-410A to become the global standard. Honeywell is the world leader in developing and manufacturing non-ozone depleting refrigerants, and we’ve never seen anything like R-410A, and neither have our customers!
