Over the past several years, both the U.S. and Canadian governments have mandated that all manufacturers of air conditioning equipment stop 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. These mandates are suppose to have the HVAC industry move to a more green friendly refrigerant with a technical code R410A. R410A has been verified to be safer for the environment.
In late 2010 reputable 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 Midway Services) can charge the unit with R22. R22 is still legal for AC repair or service for a few more years. The intent for these Dry Charged Units is to give the greater Clearwater 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 wean the industry off less eco-friendly refrigerants.
Clearwater homeowners should know that these Dry Charged Units are allowed in the U.S. and Canada. Because of some key ambiguities in the written policies, the entire outdoor unit is technically looked upon as a replacement “part”. These days, condensers or heat pumps intended for use in a replacement R-22 system are often referred to as “Dry Charge” or “Nitrogen Charged” systems. Below are some Frequently Asked Questions about this recent A/C Dry Charge trend.
Should I buy a “Dry Charge” A/C system?
The answer to this question hinges on a number of things. The number one thing to do is determine what types of HVAC equipment the heating and air conditioning industry offers and seek solutions that speaks to 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 Clearwater homeowners that Dry Charge units do not. A few of the benefits include:
- Improved energy efficiency for reduced cost of comfort
- Modern technology to reduce humidity
- Current production refrigerant solutions guaranteeing longer life and extended availability of refrigerant
- Expanded warranty periods for even greater peace of mind
- Quieter operation for a more peaceful indoor environment
- Ozone friendly refrigerant that reduces the carbon imprint that negatively impacts our environment
- Matched coil solutions for enhanced 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, 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 affords industry standard protection on the components it does not provide protection against R-22 refrigerant prices, which are expected to increase significantly.
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 slowly 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.
