What's an Air Conditioning Dry Charge?
Over the past decade, both the U.S. and Canadian governments have instructed that all manufacturers of air conditioning equipment phase out production of the refrigerant R-22 (Freon) or Hydrochlorofluorocarbons (HCFCs). These refrigerants have been commonly used in air conditioners and heat pumps for the last several decades. The recommended phase-out mandates are anticipated to have the HVAC industry turn to a more earth friendly refrigerant with a technical label R410A. R410A has been proven to be safer for the environment.
In late 2010 the majority of air conditioning companies began manufacturing Air Conditioning and Heat Pump units, without adding refrigerant at the factory. These systems are more commonly called “dry charged units”. These A/C units can legally be sold and installed then your local HVAC contractor (such as Levy & Son Service Experts) can charge the unit with R22. R22 is still legal for AC repair or service for a short time longer. The reason for these Dry Charged Units is to offer the greater Dallas area a more simple and relatively inexpensive replacement option for central air conditioners and heat pumps. However, these units also bypass the spirit of the mandates, which was to wean the industry off less eco-friendly refrigerants.
Dallas 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 looked upon as a replacement “part”. As a result, condensers or heat pumps intended for use in a replacement R-22 system are often referred to as “Dry Charge” or “Nitrogen Charged” systems. Here 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?
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 that speaks to 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 Dallas homeowners that Dry Charge units do not. A few of the benefits include:
- Improved energy efficiency for reduced cost of comfort
- State-of-the-art technology to lower humidity
- Current production refrigerant solutions guaranteeing longer life and extended availability of refrigerant
- Expanded warranty periods for even greater 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 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, however, it can only be used as a repair to an existing system.
What about the warranty?
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 significantly.
How expensive will R-22 get in the next few years?
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 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.
