Engineer found that condenser was not getting hot and suggested that compressor was not spinning fast enough and to check that it was getting 14 volts. seems odd to me as no warning lights and all other electrics working properly. Any suggestions gratefully received!
Either you have confused what the man said, or he has no business working on automotive A/C systems.
If the compressor clutch is engaged, there is no sense is saying "it may not be running fast enough". If the clutch is engaged, the pump is turning - period.
If you have the proper freon quantity, and the pump is running, you only need air blowing over the condenser (which extracts heat) for the air blowing over the evaporator to go cold. The valve right before the evaporator could be faulty, other than that, I'd consider zip's advice: The A/C may be fine, but the duovalve is open, allowing hot water to flow into the heater core, causing the vents to blow hot air. This is not an A/C failure. But this "engineer" should be able to figure that out with one eye tied behind his back...
Take it to someone who knows what the hell they are doing.
