Is your air conditioning running on R22 refrigerant ? If yes then now is the time to switch to a new system.
Not only does R22 contain ozone depleting refrigerants which contribute to environmental damage, but it alo less efficient. New systems are proven to to be more efficient and have less impact on the environment.
After 1st of January 2015 we will no longer be able to use R22 for service or maintainance.
