β Key Features
Wall Mount Indoor
Ductless wall-mount indoor units deliver targeted heating and cooling directly to individual rooms without the need for cumbersome ductwork.
Condensate Pump NOT Included
Optional condensate pump eliminates the need to gravity-drain condensate — critical for attic and closet installations where gravity drainage isn't practical.
Wireless Remote Included
Control options included: Wiresless remote. *Optional programmable wired thermostat with built-in WiFi for remote monitoring and scheduling is avaiable.
Coated Outdoor Coils
Hydrophilic coated condenser fins resist corrosion in coastal, high-humidity, and salt-air environments — extending outdoor unit service life.
Optional Freon Sensor
Detects refrigerant leaks and alerts with an error code before the system loses significant charge — reduces service call costs and prevents compressor damage from low refrigerant.
R454B — Future-Ready Refrigerant
Lower GWP than R410a, compliant with current EPA and DOE standards. Pre-charged from the factory — no field modification required for installation.

β Frequently Asked Questions
What is the difference between D5FVHAH18XCK and D5FVHAH18XAK indoor?
D5FVHAH18XCK is the default indoor without the freon sensor. D5FVHAH18XAK is an optional upgrade with freon sensor, you must select from the dropdown box.
Do I need the condensate pump for drainage?
Depends — the condensate pump is only needed where a drain line to a floor drain or exterior isn't feasible. Mount on an exterior wall, and you shouldn't need a condensate pump.
Can this unit serve multiple rooms?
No — this is a single zone unit designed for one area. For multiple rooms, please visit our multi-zone category.
Is this suitable for an office space?
Yes — the D5FVHAH18XCK or optional D5FVHAH18XAK is rated for medium sized areas. At 1.5 ton it can serve office spaces, retail units, or buildings up to approximately 800 sq ft depending on construction and climate zone.
