GarveeHome 18,000 BTU 21 SEER2 Wi-Fi Mini Split Heat Pump: specs

The GarveeHome 18,000 BTU 21 SEER2 mini split is a ductless heat pump that cools and heats one room or zone through a wall-mounted indoor unit and an outdoor unit. It is pre-charged with refrigerant and adds Wi-Fi control. Here is what its specs mean and what to confirm before installing.

Capacity and efficiency

An 18,000 BTU figure describes cooling output per hour, and GarveeHome says this unit cools up to 1,250 square feet (about 116 square metres). The right capacity depends on insulation, windows, ceiling height and climate, so use the area as a rough guide. The unit is rated at 21 SEER2, the seasonal efficiency standard: a higher figure means more cooling per unit of electricity. It runs on 230 volts, and GarveeHome describes it as AHRI certified.

How the inverter works

The listing explains that the inverter changes the frequency of the power supply to the compressor so that it does not switch on and off repeatedly. In general, this gives steadier temperatures and lower power use, and GarveeHome says it also extends the life of the unit.

What "pre-charged" means

Pre-charged means the outdoor unit already holds refrigerant. That typically lowers the work needed on site, though a qualified installer still has to connect the lines, make the electrical connections and commission the system. Follow local codes and the manual.

Modes, timer and remote

Five modes are listed: auto, cool, dry, heat and fan. Other features are automatic defrosting, self-diagnosis and cleaning, iFEEL mode, sleep mode and an energy-saving mode. The remote sets temperatures from 61°F to 88°F (about 16°C to 31°C) and has a 0.5 to 24 hour timer. Its screen turns itself off after 10 seconds without use so it does not light up the bedroom. Wi-Fi control is also listed, so check the app requirements in the manual.

Noise and airflow

GarveeHome says noise stays below 50 decibels, and airflow can reach 50 feet (about 15 m) with 4D air circulation. Noise figures are measured under test conditions, so what you hear depends on the fan speed and mounting.

Operating range

The system is designed to work in outdoor temperatures from -4°F to 140°F (about -20°C to 60°C). Heat pump output typically falls as it gets colder, so check the manual's heating performance if your winters are severe.

Size

The listing gives dimensions of 35.0 x 29.1 x 34.4 inches (89 x 74 x 87 cm). Check the manual for the separate indoor and outdoor unit sizes and the maximum refrigerant line length.

Who it suits

It suits additions, garages, workshops, basements or bedrooms without ducts, and homes that want to control one zone from a phone as well as the remote.

What to check before you buy

• Sizing: compare 18,000 BTU with your room's real heating and cooling load.
• Electrical: confirm a suitable 230V circuit and breaker, as the manual specifies.
• Installation: arrange a qualified installer and check local permit rules.
• Placement: pick a wall for the indoor unit and a spot for the outdoor unit within the line length.
• Wi-Fi: check the signal reaches the indoor unit and what the app supports.
• Upkeep: plan for regular filter cleaning, as the manual describes.
