Loujien Airconditioning Equipment! They did a great job with my challenging house. Had to re-do the venting under the house that was totally messed up by a previous owner. They did a great job and got my a/c going again in the middle of a heat wave. I'm scheduling a time for Loujien Company and crew to come back and replace my heater and A/C units to energy efficient models asap. Very honest and trustworthy. I recommend Loujien Airconditioning!
