	Badly maintained equipment or old HCFC systems may not lend themselves to conversion and could need complete replacement with a compliant HFC, hydrocarbon, ammonia or carbon dioxide system.

It is likely therefore that landlords and tenants will be looking at the small print of their leases to establish where liability lies for such costs. In some cases the courts may have to determine who pays.
