About Gask Technical Services
An HVAC company built in Manassas, VA — serving homes and businesses across Northern Virginia, D.C., and Maryland.
Our Story
Gask Technical Services, LLC was founded by Gerson Quixchan on a straightforward idea: diagnose the actual problem, quote it honestly, and install it properly. In an industry where plenty of companies sell equipment first and think about the system second, that turns out to be a difference customers notice.
We work out of 7900 Sudley Road in Manassas, Virginia, and we cover everything within an 80-mile radius of that shop — Fairfax, Tysons Corner, Burke, Alexandria, and Nokesville, west to Front Royal, north into Washington D.C., and up to Rockville and Baltimore in Maryland.
Our work covers the full system, not just the box outside: preventive maintenance and tune-ups, new installations, repairs, and the ductwork that determines whether any of it actually reaches your rooms. We serve homeowners, landlords, restaurants, offices, and commercial buildings — and returning customers save 10% on installations, repairs, and maintenance.
What We Stand For
Accuracy
We test with instruments and work from readings, so the repair addresses the real fault the first time.
Straight Talk
You get the honest repair-or-replace comparison and a firm price before anyone picks up a tool.
Craftsmanship
Correct sizing, proper evacuation, verified charge, balanced airflow. The details that decide performance.
Local Service
We are a Manassas company serving our own region. Our reputation here is the whole business.
Our Mission
Keep Northern Virginia, D.C., and Maryland comfortable year-round with heating and cooling work that is diagnosed accurately, priced honestly, and installed to spec — so the system performs the way it was designed to.
Our Promise
We will never quote a replacement when a repair genuinely serves you better, and we will not patch a system that is going to fail again next month. You get the facts and the numbers, and the decision stays yours.
