About Us
Welcome to Cornerstone Heating & Air Conditioning, Inc.
At Cornerstone Heating & Air Conditioning, Inc., we believe in doing things right — the first time. Founded with a passion for helping families and businesses stay comfortable year-round, our journey began over four decades ago in Frederick County, Maryland.
That same commitment to quality and integrity continues to drive everything we do today. From the moment you contact us to the final system check, we focus on providing reliable service, honest advice, and long-term solutions. Our experience has taught us that true comfort goes beyond temperature control — it’s about trust, responsiveness, and knowing your HVAC partner has your back through every season.
Our Story
Our founder’s HVAC journey started in high school through Frederick County Vo-Tech, followed by a scholarship to Lincoln Tech Institute. From hands-on experience in the DC Metro area to working with reputable companies like Southern States and Ewing Oil, the foundation was laid for a company rooted in integrity, skill, and service. After years of sharpening our craft — including time with a plumbing company — Cornerstone Heating & Air Conditioning, Inc. was born.
Our Mission
To deliver dependable, energy-efficient heating and cooling solutions backed by superior workmanship, transparent service, and a team that genuinely cares.
