About On Call Diesel Service
John runs On Call Diesel Service, a mobile diesel mechanic shop based in Clermont. He's been at it over 20 years and works on motorhomes, big rigs, and heavy equipment. You'll see him at your site or roadside in the Four Corners area of Polk and Lake Counties. Reviewers keep mentioning the same things: he shows up when he says he will, explains what's wrong in plain language, and doesn't gouge you on price. One person said he arrived within 30 minutes of a call and had them back on the road in under an hour. Another had a brake and air system issue on their RV that he diagnosed and temporarily fixed on the spot. The 45 Google reviews average a perfect 5.0. He handles oil changes, brakes, batteries, electrical, steering and suspension, air conditioning, generator repair, and engine diagnostics. He's a mobile mechanic, so he comes to you. Call to set up a time.
