I had my Lennox 3 ton a/c unit recharged last night and it was working fine and cooled the house down quickly. However, later in the night when it kicked on it had a huge draw on the electricity as if something would not start. Then it turned off, then tried to turn on again. It again dimmed the lights but then did successfully turned on. After it ran a while I turned up the thermostat so it would turn off, then turned it off completely. Does anyone have an idea what now might be going on?
