Over the past decade, both the U.S and Canadian governments have mandated that all manufacturers of air conditioning equipment halt production of the refrigerant R-22 (Freon) or Hydrochlorofluorocarbons (HCFCs). These refrigerants have been standardly used in air conditioners and heat pumps for a long time. The R-22 and HCFC mandates are intended to have the HVAC industry shift to a more green friendly refrigerant with a technical code R410A. R410A has been proven to be safer for the environment.
In late 2010, most air conditioning firms began manufacturing Air Conditioning and Heat Pump units without adding refrigerant at the factory. Such systems are more commonly called “dry charged units”. The units can legally be sold and installed. R22 is still legal for AC repair or service for a while longer. The reason for these Dry Charged Units is to offer the greater the U.S. area a more simple and cost cost-effective 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.
the U.S. homeowners should understand 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 now referred to as “Dry Charge” or “Nitrogen Charged” systems. Below 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 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.
Top Reasons for Buying an R-410A System
Current R-410A systems provide benefits to U.S. homeowners that Dry Charge units do not. A sample of the benefits include:
- Increased energy efficiency for reduced cost of comfort
- Modern technology to lessen humidity
- Current production refrigerant solutions guaranteeing longer life and extended availability of refrigerant
- Expanded warranty periods for more peace of mind
- Quieter operation for a more peaceful indoor environment
- Eco friendly refrigerant for lower impact on the environment
- Matched coil solutions for increased reliability and guaranteed cooling and heating performance
Are Dry Charge Units Legal?
Absolutely. There are no Federal laws or legal restrictions on the installation of R-22 or Dry Charge Equipment, as long as it is as a repair for an existing system.
Is There a Warranty That Comes With It?
Major 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 dramatically.
Is R-22 Refrigerant Going to Get Really Expensive?
As the phase out process of R22 continues, new R-22 refrigerant production will slowly 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.
