What's an Air Conditioning Dry Charge?
Over the past 10 years, both the U.S. and Canadian governments have mandated 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 many decades. These mandates are expected 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. 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 for a short time longer. The purpose of these Dry Charged Units is to give the greater Fort Worth area a more simple and affordable replacement option for central air conditioners and heat pumps. However, these units also circumvent the spirit of the mandates, which was to help the environment by introducing more environment friendly solutions.
Fort Worth 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”. Today, 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.
Do you recommend purchasing a Dry Charge Air Conditioning System?
Well, it really depends on a number of things. The most important 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 Fort Worth homeowners that Dry Charge units do not. Some of the benefits include:
- Greater energy efficiency for reduced cost of comfort
- State-of-the-art technology to lessen 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 for lower impact on the environment
- Matched coil solutions for enhanced reliability and guaranteed cooling and heating performance
Are Dry Change Air Conditioning Unit legal to install?
Absolutely. 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.
Does a warranty come with a Dry Charge Unit?
Most 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 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 progressively 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.
