I am in process of purchasing a house and they had an HVAC

This answer was rated:

I am in process of purchasing a house and they had an HVAC inspection performed prior to putting it on the market. The invoice they provided states that the "contactor is blackening starting to arch" and also that "the fan is running over max amps of 1.5, running at 1.8"

The furnace is a 2004 Armstrong.

I do not know much about furnaces, are these issues I should be worried about?

I will be glad to help you with your question today.

The inspector probably meant the the contactor points were "arcing"

This would cause them to turn black from over heating. The contactor should be replaced as a preventative action. The fan motor is drawing more electricity that what is shown on the rating plate. Again, this is a indication that it may be starting to wear out. You did not state how old the unit was, but as in mechanical devices, things where out and have to be replaced. Neither of these would necessarily mean it would fail in a unusally short time. But the inspector is just doing his job bringing it to your attention. The contactor is a easy replacement. The motor is a little more involved and would require the services of the technician. If you are concerned about it, have the owner replace the parts before you purchase the home.

I hope this a made things a little more understandable for you.

Would you consider either of these issues a safety hazard?

no, just a future repair bill and maybe a hot evening if it breaks at a bad time ;)
