Air Conditioning

The Federal Environmental Protection Agency regulates the type of refrigerant you can use in your air conditioner.  Your M.E. “Gene” Johnson Service technicians are current on EPA rules for properly removing & recycling of used refrigerant, protecting the environment while keeping you cool.


Car batteries do not last as long in our warm Texas climate.  Cold starts put a greater demand on batteries, but heat is a bigger factor in the life of a car’s battery.  We can test your car battery for how well it holds a charge and how much life it has left, and we will replace it if necessary.

Disc Brakes & Drum Brakes

Some vehicles have disc brakes on the front & drum brakes on the rear.  If you are hearing unusual sounds when you brake or if your brake pedal is feeling mushy or too hard, to keep you safe, your M.E. “Gene” Johnson Service technicians will do a brake inspection for you.

Computer Diagnostics

If your “check engine” light has come on, our computer diagnostic service can quickly alert us to what is wrong with your car.  All cars manufactured today contain at least one computer. It is in charge of monitoring engine emissions and adjusting the engine to keep emissions as low as possible. The computer receives information from a many different sensors, including:

Using the information from these sensors, the computer can control things like the fuel injectors, spark plugs and the idle speed to get the best performance possible from the engine while keeping emissions low.  Depending on how expensive the car is, there can be all sorts of other computers. For example:

Please note: If you take the battery out of your car to replace it, all of the computers lose power. Your radio, for example, may forget its preset stations.

Electrical Services

Many malfunctions that occur in vehicles can be diagnosed as automotive electrical problems. The source of these problems is usually related to the electricity that is being generated by the battery or alternator.
