I am a transient commuter and I drive back and forth between my job and home. My AC unit went out while I was at home and I called MobileTech to schedule an appointment upon my return to the trailer. The actual owner, David Franklin was there ahead of set appointment time and I showed up as well. Started the work earlier than appointment time, explained the problem, showed my the problem and provided suggestions for repair. The repair was the entire AC unit had to be replaced, Mr. Franklin had to go back to the shop to get the correct AC unit and brought back another tech to assist. All in the heat of the day. But he kept his promise, I would have AC before he was done. All work was professionally done, everything worked, they also cleaned up after repair and hauled away old AC unit. I highly recommend this company for any repairs you need for your RV. I will definitely be using again, if needed.
