What's an Air Conditioning Dry Charge?

April 01, 2015

Over the past several years, both the U.S. and Canadian governments have instructed that all makers of air conditioning equipment halt production of the refrigerant R-22 (Freon) or Hydrochlorofluorocarbons (HCFCs). These refrigerants have been standardly used in air conditioners and heat pumps for a long time. The R-22 and HCFC mandates are anticipated to have the HVAC industry move to a more earth friendly refrigerant with a technical designation R410A. R410A has been shown to be safer for the environment.

In late 2010 most air conditioning manufacturers began manufacturing Air Conditioning and Heat Pump units, without adding refrigerant at the factory. These units are more commonly called “dry charged units”. These A/C units can legally be sold and installed then your local HVAC contractor (such as Service Experts Heating & Air Conditioning) can charge the unit with R22. R22 is still legal for AC repair or service a while longer. The reason for these Dry Charged Units is to give the greater Naples 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 to wean the industry off less eco-friendly refrigerants.

Naples homeowners should know that these Dry Charged Units are allowed in the U.S. and Canada. Because of the lack of clarity regarding the definition of an outdoor unit in the rules, 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 now referred to as “Dry Charge” or “Nitrogen Charged” systems. Here are some Frequently Asked Questions about this recent A/C Dry Charge trend.

Do you recommend purchasing a Dry Charge Air Conditioning System?

It depends on a number of things. The number one thing to do is learn what types of HVAC equipment the heating and air conditioning industry offers and seek solutions to meet 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.

Top reasons for buying an R-410A system

Current R-410A systems have many benefits to Naples homeowners that Dry Charge units do not. Some of the benefits include:

  • Greater energy efficiency for affordable in-home comfort
  • State-of-the-art technology to reduce humidity
  • Current production refrigerant solutions allowing longer life and extended availability of refrigerant
  • Extended warranty periods for even greater peace of mind
  • Quieter operation for a more peaceful indoor environment
  • Earth friendly refrigerant for lower impact on the environment
  • Matched coil solutions for increased reliability and guaranteed cooling and heating performance

Are Dry Change Air Conditioning Unit legal to install?

Yes. There are no Federal laws or legal restriction on the installation of R-22 or Dry Charge Equipment, with the stipulation that it is repairing an existing air conditioning system.

Does a warranty come with a Dry Charge Unit?

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

How expensive will R-22 get in the next few years?

It is likely that as a result of supply and demand, the answer to this question is “yes – we do anticipate R-22 refrigerant to get pricey”. As the phase out process of R22 continues, new R-22 refrigerant production will gradually 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.
