RV Air Conditioning

[Gunslinger]

Section 609 Certification allows the purchase of any refrigerant in any size container from an auto supply house for use in cooling the passenger compartment of vehicles!
Motor Vehicle Air Conditioners (MVAC) are defined as mechanical vapor compression refrigeration equipment used to cool the driver or passenger compartments of any motor vehicle. This definition is NOT intended to encompass the hermetically sealed refrigeration system used on motor vehicles for refrigerated cargo or the air conditioning systems on passenger buses which use HCFC-22 refrigerant. Section 609 certification is required for working on MVAC systems while Section 608 certification is required for working on non-motor vehicle air conditioning systems. Note that Section 608 certification is required for working on hermetically sealed refrigeration systems used on motor vehicles for refrigerated cargo or the air conditioning systems on passenger buses which use HCFC-22 refrigerant.

Anybody can buy 134-A in the auto parts store.

There will be a time in the near future that the public can not purchase 134a.

I think they cost around $1200 now. They are never "On Sale" or "Reduced Price" on those units. Take your lumps old bud, Roy

When they're on vaction, they don,t have $1200 or so extra planned just to be comfortable. They just want it to get through their trip. They would rather have some reserve in case of a major breakdown.
