Over the past decade, both the U.S. and Canadian governments have instructed 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 the last several decades. The R-22 and HCFC mandates are suppose to have the HVAC industry shift to a more earth friendly refrigerant with a technical designation R410A. R410A has been proven to be safer for the environment.
In late 2010 most air conditioning producers began manufacturing Air Conditioning and Heat Pump units, without adding refrigerant at the factory. Such systems are more commonly called “dry charged units”. They can legally be sold and installed allowing the HVAC contractor to charge the unit in the field with R22. R22 is still legal for AC repair or service a while longer. The purpose of these Dry Charged Units is to offer the greater Hilton Head Island 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.
Hilton Head Island homeowners should know 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 deemed 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.
Do you recommend purchasing a Dry Charge Air Conditioning System?
Well, it really 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 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 offer benefits to Hilton Head Island homeowners that Dry Charge units do not. Some of the benefits include:
- Increased energy efficiency for affordable in-home comfort
- Modern technology to reduce humidity
- Current production refrigerant solutions guaranteeing longer life and extended availability of refrigerant
- Longer warranty periods for significant peace of mind
- Quieter operation for a more peaceful indoor environment
- Eco friendly refrigerant that protects the environment
- Matched coil solutions for increased 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, however, it can only be used as a repair to 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.
Is R-22 refrigerant going to get really expensive?
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 gradually be reduced, with full elimination of its production in 2020. Until that date, indications are that there will likely be sufficient supply to meet the current demand.
