Maryland Certified Emissions Repair Facilities

Check Engine Light Logo 
 
Maryland Certified Emissions Repair Facilities (CERFs) employ skilled Master Certified Emissions Technicians, who have earned the highest national recognition for expertise in emissions repairs.
Motorists should consider that specialized training and experience may be necessary to perform effective emissions repairs, but motorists are not required to have repairs done at a CERF.

All CERFs are equipped with the diagnostic equipment needed to repair vehicles that fail the On-Board Diagnostics (OBD) Test. Some are also equipped to perform Idle Test repairs. Some CERFs may limit repairs to specific vehicle manufacturers or models.
