Our Story
A United HVAC & Plumbing was founded with a simple belief: homeowners deserve straight answers, fair prices, and work done right the first time. Too many contractors in Northern Virginia had built a reputation for upselling, vague pricing, and sending unlicensed technicians to do licensed work. We set out to be different.
Starting with a single service van and a commitment to quality, we've grown into one of Northern Virginia's most trusted HVAC and plumbing companies — serving thousands of homeowners across Fairfax, Arlington, Alexandria, Springfield, and Falls Church.
Every technician we send to your home is a licensed professional. Every quote we give is the price you pay. And every job we complete is backed by our satisfaction guarantee. That's not a marketing promise — it's how we've built our business.
