A failing rooftop air conditioner can turn an East Texas summer trip miserable in a hurry. TrailTech RV diagnoses and repairs RV air conditioners on-site — whether you have a single rooftop unit or a multi-zone ducted system — so you never have to drag your rig to a shop and wait.
Our RVTAA-certified technicians carry the most common parts and test equipment with them, which means many A/C problems are diagnosed and repaired in a single visit.
