Used them in a pinch when ac went down on a hot Sunday. Techs were rather clueless and I should have turned them away immediately. Instead I ended up replacing a $50 part for $500 that ultimately didn't solve the problem. When they suggested another $700 in work I wised up and sent them home. The fix they thought they put in ended up damaging the unit further. Request for personal check straight to the owner was the cherry on the cake. Steer clear at all costs!
