Right now, a CompTIA A+ certificate shows that you have at least 6 months 'on the job' training in the field of PC hardware and Operating System repair. That and $1.90 will get you a cup of coffee at Starbucks.
OK that was Rockin's standard reply . . . still true
Now mine . . .
Yes, by all means, get your A+ cert, then N+ cert. It shows that you are willing to continue your training to continue to improve. That will help get your foot in the door for a career in the IT field. Some companies that I have talked to has that certificate as a requirement. The entry level jobs are Help Desk Tier I or Systems Support Specialist and in the DC area they start at 24,000 a year.
good luck
