See What RV Owners Say Before You Schedule.
"Our rooftop A/C gave out right as summer hit 102 degrees in Lancaster. Javi's shop diagnosed the start capacitor and control board, replaced them same-day, and inspected our roof seams for free. Outstanding honest service!"
"I had a mysterious 12V battery drain that two other places couldn't figure out. Brought it into Javi's shop in Lancaster. They found a short in the slide-out motor wiring in 2 hours and fixed it cleanly. Reasonable price and super knowledgeable."
"Installed a 400W solar panel system withVictron MPPT controller and dual Lithium batteries on my toy hauler. Now I can dry camp in Cal City all weekend without running the generator! Fantastic workmanship."
