Last year, I called Dave's to come out to my fifth wheel on a seasonal site. Both of my air conditioners were not working. Dave showed up at the agreed upon time, assessed both air conditioners, and advised that he would submit the info to Dometic for warranty repairs. Later, he called to tell me he had two new AC units and needed to schedule a time to install them. They have worked well since then. I wouldn't hesitate to call for Dave's service again.
