A-1 Radiator Service is your best choice for all types of radiator services in Edmond and its surrounding communities near Oklahoma City.


Since the day Lloyd Thrash opened the doors to the business in 1964...we have been committed to providing our customers with the best cooling system service possible.  


​Lloyd built a successful business by adhering to a simple principle: provide your customers with honest service and affordable prices...and everything else will fall into place. 


Lloyd's son Don has maintained the same approach since taking over the operation in 1991 and now serves second and third generation relatives of Lloyd's original customers as well as  many newcomers to the area.
