What's an Air Conditioning Dry Charge?

April 01, 2015

Over the past several years, both the U.S. and Canadian governments have mandated 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 many decades. The recommended phase-out mandates are anticipated to have the HVAC industry turn to a more environmentally friendly refrigerant with a technical designation R410A. R410A has been verified to be safer for the environment.

In late 2010 reputable air conditioning manufacturers began manufacturing Air Conditioning and Heat Pump units, without adding refrigerant at the factory. These systems are more commonly called “dry charged units”. They can legally be sold and installed which permits your Gainesville area HVAC contractor to charge the unit on-site with R22. R22 is still legal for AC repair or service for a short time longer. The intent for these Dry Charged Units is to offer the greater Gainesville area a more simple and cost effective replacement option for central air conditioners and heat pumps. However, these units also dodge 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.

Gainesville homeowners should understand 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 looked upon as a replacement “part”. These days, condensers or heat pumps intended for use in a replacement R-22 system are usually referred to as “Dry Charge” or “Nitrogen Charged” systems. The following are some Frequently Asked Questions about this recent A/C Dry Charge trend.

Should I buy a “Dry Charge” A/C system?

It depends on a number of things. The best thing to do is determine 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.

Why would I buy a R-410A refrigerant system?

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

  • Increased energy efficiency for affordable in-home comfort
  • Leading technology to reduce humidity
  • Current production refrigerant solutions guaranteeing longer life and extended availability of refrigerant
  • Longer warranty periods for even greater peace of mind
  • Quieter operation for a more peaceful indoor environment
  • Eco 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?

Yes. 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?

Major manufacturers have 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 dramatically.

Will the R-22 refrigerant be expensive to buy?

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 slowly be reduced, with full elimination of its production in 2020. Until that time however, indications are that there will likely be sufficient supply to meet the current demand.
