Our Story

Founded on Trust and Quality

ParkerCoolFix was born from a simple belief: everyone deserves a comfortable, climate-controlled home. In 1995, our founder Terry Parker started the company with just one truck and a commitment to honest, reliable service.

What began as a small family business in Frederick has grown into Maryland's most trusted HVAC service provider. Over 25 years later, we still hold the same values: technical excellence, transparent pricing, and treating every customer like family.

Today, we're proud to have served over 5,000 Maryland families and businesses, maintaining our reputation for quality work and exceptional customer service. Every job is completed with the same attention to detail and care that Terry demanded from day one.
