Over the past several years, both the U.S. and Canadian governments have instructed that all producers of air conditioning equipment phase out 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 intended to have the HVAC industry move to a more earth friendly refrigerant with a technical label 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. These systems are more commonly called “dry charged units”. They can legally be sold and installed then your local HVAC contractor (such as San Antonio Air Service Experts) can charge the unit with R22. R22 is still legal for AC repair or service for a short time longer. The purpose of these Dry Charged Units is to provide the greater San Antonio 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 help the environment by introducing more environment friendly solutions.
San Antonio homeowners should know that these Dry Charged Units are approved in the U.S. and Canada. Taking advantage of an unclear definition of the outdoor unit in these 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. The following 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 number one thing to do is understand 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 offer benefits to San Antonio homeowners that Dry Charge units do not. A sample of the benefits include:
- Increased energy efficiency for affordable in-home comfort
- State-of-the-art technology to lessen humidity
- Current production refrigerant solutions guaranteeing longer life and extended availability of refrigerant
- Expanded warranty periods for significant peace of mind
- Quieter operation for a more peaceful indoor environment
- Ozone friendly refrigerant for lower impact on the environment
- Matched coil solutions for enhanced 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, with the stipulation that it is repairing an existing air conditioning system.
What about the warranty?
Major manufacturers honor 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 significantly.
How expensive will R-22 get in the next few years?
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 time however, indications are that there will likely be sufficient supply to meet the current demand.
