Hi, I’m Jon Costa, owner of MaineLine PCs with over 15 years of hands-on experience in computers and technology. What started as a childhood fascination—taking apart old computers, swapping parts, and bringing machines back to life—has grown into a lifelong passion and a full-time local business serving our community.

I’m CompTIA A+ certified and currently pursuing a bachelor's degree in Cybersecurity, which helps me stay current in a fast-paced tech landscape. My mission is simple: to provide honest, high-quality service that solves your tech problems efficiently and affordably—whether you're dealing with a sluggish system, a virus, or want a custom-built rig that delivers serious performance.

At MaineLine PCs, I offer a wide range of services, including:

• PC repairs and upgrades

• Virus and malware removal

• System maintenance and performance tuning

• Networking setup and troubleshooting

• Custom PC builds for gamers, creators, and professionals

• Overclocking and performance tweaks

I treat my customers the way I’d want to be treated—with respect, transparency, and integrity. No upsells, no gimmicks—just real solutions from someone who genuinely cares about getting your system running right.
