Over the past several years, both the U.S. and Canadian governments have mandated that all producers of air conditioning equipment halt production of the refrigerant R-22 (Freon) or Hydrochlorofluorocarbons (HCFCs). These refrigerants have been commonly used in air conditioners and heat pumps for many decades. The recommended phase-out mandates are anticipated to have the HVAC industry move to a more environmentally friendly refrigerant with a technical code R410A. R410A has been proven to be safer for the environment.
In late 2010 reputable air conditioning producers 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 Service Experts Heating & Air Conditioning) can charge the unit with R22. R22 is still legal for AC repair or service for a few more years. The reason for these Dry Charged Units is to provide the greater Raleigh area a more simple and affordable 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.
Raleigh homeowners should be aware 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 now referred to as “Dry Charge” or “Nitrogen Charged” systems. Below 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 number one thing to do is determine what types of HVAC equipment the heating and air conditioning industry has to 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.
Why would I buy a R-410A refrigerant system?
Current R-410A systems offer benefits to Raleigh homeowners that Dry Charge units do not. A sample of the benefits include:
- Increased energy efficiency for reduced cost of comfort
- Modern technology to reduce humidity
- Current production refrigerant solutions ensuring longer life and extended availability of refrigerant
- Longer warranty periods for more peace of mind
- Quieter operation for a more peaceful indoor environment
- Earth friendly refrigerant that protects the environment
- Matched coil solutions for enhanced reliability and guaranteed cooling and heating performance
Are Dry Charge units legal?
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.
Is there a warranty that comes with it?
The majority of manufacturers have established a standard 5-year parts warranty on dry charge units. While this affords 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 refrigerant will probably go up in price. As the phase out process of R22 continues, new R-22 refrigerant production will progressively 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.
