Arminco Air provides commercial HVAC services across Ashburn, VA, one of the busiest commercial and technology hubs in Loudoun County.

Mission-critical cooling is a core part of our Ashburn work. We design, install, and service precision cooling for server rooms and data halls, including computer room air handler (CRAH) units and computer room air conditioner (CRAC) units matched to your rack density, airflow strategy, and redundancy requirements. Our team supports hot and cold aisle containment and continuous monitoring to protect uptime in high-density environments.
Beyond data centers, AAI keeps Ashburn’s offices, retail spaces, and industrial facilities comfortable and code-compliant year-round. For larger cooling and process loads, we install and maintain industrial chillers sized for continuous operation. Whether you manage a single building or a growing portfolio, our team builds a maintenance plan that fits your operations and budget.
