I recently had them out to perform a pre-summer maintenance check on my units. The repair man told me one unit was dead and the other one was on it's way out. I could repair the dead one for $4000 or replace it for $7000. He said he disconnected the dead unit to spare my power bill because it would run constantly and only blow out hot. I sat on it for a bit and called another company who came over yesterday. He connected the unit and it works perfectly. Blows nice and cold.
I doubt my A/C unit repaired itself so I can only assume Larson Air was trying to rip me off. Dirty pool guys.

I got through the summer with both of my 'dead' units working just fine and blowing cold air.

Both "dead" units are still working and blowing cold.
