RXL18WMVJU9 + FDMQ18WVJU9
Daikin 18,000 BTU 1.5 Ton
Single-Zone Slim Duct
Ductless Heat Pump
The RXL18WMVJU9 is a Daikin regular (standard) single-zone slim-duct ductless heat pump paired with the matching FDMQ concealed indoor unit. It delivers inverter-driven comfort while keeping the indoor unit out of sight — air is supplied through grilles from short, well-designed duct runs.
This 1.5-ton size is for larger zones that need real capacity — bigger basements, open concept main-floor areas, large family rooms, or spaces with significant window load. It’s also a good option when you want a “clean ceiling” look but still want ductless-level efficiency and modulation.
At this size, oversizing is still a risk if the zone doesn’t truly need it. We confirm the match based on the actual heat loss/gain and how the space is used — not just square footage. And again: if your goal is dependable primary heat through Ottawa winter, cold-climate equipment is typically the right category; regular series is often best for cooling + shoulder-season heat.
We confirm sizing and pricing on site – no pressure, no upsells.

Key features of Daikin Regular Single-Zone Slim Duct (FDMQ + RX)
- Concealed “slim duct” indoor unit: the equipment is hidden (typically in a ceiling/soffit), with comfort delivered through discreet supply grilles instead of a visible wall head.
- Inverter-driven comfort: modulates output for steadier temperatures and fewer big swings than basic on/off systems.
- Best when duct runs stay short: slim-duct performs best with simple, short duct layouts and a properly sized return — not long, restrictive runs.
- Comfort that’s easier to “aim”: grilles let you place airflow where it’s needed (great for bedrooms, basements, and awkward layouts).
- Noise and performance depend on airflow setup: correct duct sizing, return strategy, and static pressure are what keep it quiet and delivering the capacity you paid for.
- Clean, code-true install approach (Peak Comfort standard): tidy line routing, correct drainage planning, pressure test + evacuation, and startup/commissioning with real checks — not guesswork.
- No upsell / no scare tactics: we confirm sizing and placement on-site and give clear options and pricing.
