Can a maintenance mistake cause freon to leak from unit?
A certified Air Conditioning Tech came out and did a maintenance check on my central ac system one morning and told me that everything was okay.
He specifically said the ac unit did not need Freon, the unit was working fine when he left, I went to work. When I returned home the inside temperature was 92. The central air conditioner unit was blowing out warm air.
When Tech returned he said no Freon was in unit. Could something have been done by the Tech doing the maintenance check to leak the Freon out?
