Where the RXQ09ASBU9 fits

This is the OTERRA outdoor heat pump by itself — 9,000 BTU, no indoor head included. Order it this way when you are replacing a failed condenser and keeping the indoor unit, or when you are building the system up piece by piece.

It is an inverter-driven, single-zone unit on R-32. It runs on 115 V, which means a standard household circuit rather than a new 240-volt run — that alone can save a few hundred dollars of electrical work on a retrofit. A working system also needs the matching OTERRA indoor head and a correctly sized line set. Heat pump means it both cools and heats, so it is the outdoor unit for a year-round install rather than cooling only.

See the rest of the line in Daikin OTERRA systems, or start from the room instead with our HVAC sizing tool. For help matching an indoor unit to an outdoor unit, call (877) 843-4822 and we will check the model numbers against Daikin’s tables before you buy.

Where the RXQ09ASBU9 fits

A heat pump is an air conditioner that can run in reverse: in winter it pulls heat from outdoor air and moves it inside, which is far cheaper than resistance heat in most of the country. The RXQ09ASBU9 pairs with a matched indoor coil or air handler, and in cold climates it is often installed dual-fuel with a gas furnace that takes over below the balance point.

Inverter (variable-capacity) heat pumps modulate output to match the load, which keeps the house closer to setpoint, runs quieter and pulls the best efficiency numbers; single-stage units cost less up front and are simpler to service. Both need a matched indoor coil to hit their ratings.

What to check before you order

• Tonnage from a load calculation; SEER2 and HSPF2 for your climate.
• Matched indoor coil or air handler with the same refrigerant (AHRI-listed pairing).
• Thermostat with an O/B reversing-valve terminal, or a dual-fuel thermostat if pairing with a furnace.
• Electrical service, pad, disconnect and line set (sold separately).

Installation and service notes

Outdoor heat pumps sit on a pad raised above snow and grass level with clearance for defrost water to drain, a disconnect within sight, and a line set sized and run within the manufacturer’s length and lift limits. Commission it in both heating and cooling modes and confirm the reversing valve and defrost cycle operate before you leave.
