Notice To Owner/Installer

This unit is designed for easy installation by an experienced person. It is legal for a homeowner to install it, however we highly recommend using a licensed HVAC technician for installation.

Legal Information About Self-Installing R410A Air Conditioners

A homeowner with a vacuum pump, proper training, and equipment can install this unit. Unless you are experienced with installing air conditioners we recommend you hire a professional installer. The person who installs the system must do all work in compliance with local building and electrical codes.

Are there any restrictions on the purchase of R410A refrigerants? R410a is not an ozone-depleting substance. At this time the purchase of R410a refrigerant is not restricted in the US. There is no technician certification requirement for those that purchase HFC refrigerants, such as R-410a or R134a. If you are not licensed, some local HVAC supply companies may refuse to sell you R410a based on a misunderstanding of the law, or because they wish to discourage homeowners from working on their own systems.

Are there any restrictions on the use of R410A refrigerants? Yes, it is illegal to knowingly vent or release these refrigerants. The venting prohibition applies to R410a, and all other HFC refrigerants, just as it does for ozone-depleting refrigerants like R-22.

Is EPA technician certification required to service R410A systems?

No, at this time EPA technician certification is not required in order to service R-410a systems. Source: http://www.epa.gov/ozone/title6/phaseout/technicians_contractors_faq.html
