Fast, Clean & Reliable Ductless HVAC Installation
Looking to cool or heat a space without installing ductwork? A ductless mini-split system is the smart choice for homeowners and small businesses across Northern Virginia and the DC Metro area. At The Flexline, we specialize in precision installation, repair, and maintenance of mini-split systems — ensuring optimal performance, efficiency, and reliability from day one.
Ductless Mini-Split Installation – Done Right the First Time
Mini-split systems are only as good as the team that installs them. Poor installation leads to energy loss, short-cycling, or even water damage. At The Flexline, our licensed HVAC technicians follow strict guidelines for:
Outdoor Unit Placement
- Mounted on brackets or elevated pads
- Positioned for full airflow and safe drainage
- Protected from debris, snow, and flooding
Indoor Head Unit Placement
- Installed on load-bearing walls
- Properly positioned for balanced airflow
- Away from vents, direct sun, or obstructions
Line & Electrical Work
- Refrigerant lines fully insulated and leak-free
- Drainage pitched and routed to prevent water backup
- Systems vacuumed, pressure-tested & fully commissioned
We don’t cut corners — we build systems that last.
