Central Air

[Ray]

1988 with central air. Unit will engage, but no cold air. Suggestions? And do you know who manfactured these units?
Thank you

Dometic manufactured these air conditioning units under the DuoTherm trade name. They are similar in design and operation to home central air conditioning. Often, a qualified residential a/c technician can service the units. If you would like to trouble shoot the units yourself, I suggest you clean your filters first. Check the amp draw at the breaker. Each compressor should draw 10 to 13 amps. If your amp draw is too, low check the freon. If your draw is too high, you might need a compressor or fan motor.
