What's an Air Conditioning Dry Charge?

April 01, 2015

Over the past decade, both the U.S. and Canadian governments have mandated that all makers of air conditioning equipment stop production of the refrigerant R-22 (Freon) or Hydrochlorofluorocarbons (HCFCs). These refrigerants have been typically used in air conditioners and heat pumps for many decades. The recommended phase-out mandates are suppose to have the HVAC industry turn to a more environmentally friendly refrigerant with a technical code R410A. R410A has been verified to be safer for the environment.

In late 2010 most air conditioning companies began manufacturing Air Conditioning and Heat Pump units, without adding refrigerant at the factory. These units are more commonly called “dry charged units”. They can legally be sold and installed which permits your Sharonville area HVAC contractor to charge the unit on-site with R22. R22 is still legal for AC repair or service for a few more years. The intent for these Dry Charged Units is to give the greater Sharonville area a more simple and affordable replacement option for central air conditioners and heat pumps. However, these units also circumvent the spirit of the mandates, which was intended to better protect our environment by moving the air conditioning industry to a more environmentally friendly refrigerant.

Sharonville homeowners should understand that these Dry Charged Units are approved in the U.S. and Canada. Because of some key ambiguities in the written policies, the entire outdoor unit is technically considered a replacement “part”. Today, condensers or heat pumps intended for use in a replacement R-22 system are usually referred to as “Dry Charge” or “Nitrogen Charged” systems. Below are some Frequently Asked Questions about this recent A/C Dry Charge trend.

Does it make sense to buy a Dry Charge Air Conditioning Unit?

Well, it really depends on a number of things. The most important thing to do is understand what types of HVAC equipment the heating and air conditioning industry can offer and seek solutions to address your personal comfort, efficiency and lifestyle needs. Take time to understand the benefits and difference between a dry charge unit and new air conditioning products with R-410A refrigerant.

Reasons to buy an R-410A refrigerant system

Current R-410A systems provide benefits to Sharonville homeowners that Dry Charge units do not. A sample of the benefits include:

  • Increased energy efficiency for affordable in-home comfort
  • State-of-the-art technology to lessen humidity
  • Current production refrigerant solutions guaranteeing longer life and extended availability of refrigerant
  • Extended warranty periods for more peace of mind
  • Quieter operation for a more peaceful indoor environment
  • Earth friendly refrigerant that reduces the carbon imprint that negatively impacts our environment
  • Matched coil solutions for improved reliability and guaranteed cooling and heating performance

Is it legal to install Dry Charge units?

Definitely. There are no Federal laws or legal restriction on the installation of R-22 or Dry Charge Equipment, as long as it is as a repair for an existing system.

Does a warranty come with a Dry Charge Unit?

Most manufacturers have a standard 5-year parts warranty on dry charge units. While this provides industry standard protection on the components it does not provide protection against R-22 refrigerant prices, which are expected to increase substantially.

Will the R-22 refrigerant be expensive to buy?

It is likely that as a result of supply and demand, R-22 refrigerant will become more expensive. As the phase out process of R22 continues, new R-22 refrigerant production will slowly be reduced, with full elimination of its production in 2020. Until then, indications are that there will likely be sufficient supply to meet the current demand.
