Over the past decade, both the U.S. and Canadian governments have directed 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 R-22 and HCFC mandates are expected to have the HVAC industry shift to a more green friendly refrigerant with a technical code R410A. R410A has been verified to be safer for the environment.
In late 2010 the majority of 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 then your local HVAC contractor (such as TML Service Experts) can charge the unit with R22. R22 is still legal for AC repair or service for a short time longer. The reason for these Dry Charged Units is to give the greater Boise 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 to help the environment by introducing more environment friendly solutions.
Boise homeowners should be aware that these Dry Charged Units are permitted 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 considered a replacement “part”. As a result, 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?
It 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 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 have many benefits to Boise homeowners that Dry Charge units do not. A sample of the benefits include:
- Greater energy efficiency for affordable in-home comfort
- Modern technology to lower humidity
- Current production refrigerant solutions allowing longer life and extended availability of refrigerant
- Expanded warranty periods for even greater peace of mind
- Quieter operation for a more peaceful indoor environment
- Earth 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?
Yes. There are no Federal laws or legal restriction 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?
The majority of 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 substantially.
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 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.
