FAQ

Optimal performance for the COOL, HEAT, and DRY modes can be achieved in the following temperature ranges. When your air conditioner is used outside of these ranges, certain safety protection features will activate and cause the unit to perform less than optimally. 

Inverter Split Type 

Room Temperature:
COOL mode:  63°F - 90°F (17°C - 32°C); 
HEAT mode: 32°F - 86°F (0°C - 30°C); 
DRY mode: 50°F - 90°F (10°C - 32°C) 

Outdoor Temperature:
COOL mode: 32°F - 122°F (0°C - 50°C); 
COOL mode for models with low temp. cooling systems 5°F - 122°F (-15°C - 50°C) 
HEAT mode: 5°F - 86°F (-15°C - 30°C) 
DRY mode: 32°F - 122°F (0°C - 50°C) 

For units with auxiliary electric heater, When the outside temperature is below 0°C (32°F), we strongly recommend keeping the unit plugged in at all times to ensure smooth ongoing performance.

This means the outdoor unit is in defrost mode, heat pumps will initiate defrost upon demand. It's a normal operation code

A mini-split air conditioner is a cooling/heating system that includes an indoor air handler and an outdoor compressor. These systems are ductless and are connected by 2 lines with refrigerant and two electric wires going from one unit to the other.

It depends on air pollution in your area. Validity of the filter can vary depending on whether you live in the country or an air conditioner is installed on a busy street in downtown. Pre-filters are subject to regular cleaning and washing in warm water. They are not replaceable. There are replaceable filters that should be replaced after 5-8 months of usage. There are reusable filters as well: they require cleaning every month, but their period of service lasts 2-3 years.

There are some simple things you can do to save energy when using an air conditioner: Install the air conditioner (or outdoor unit of a split system) on the shady side of the building (or shade the air conditioner itself); make sure the air flow around it isn't obstructed. The temperature of a heated room in winter should be between 18-21°C while the temperature of a cooled room in summer should be about 23-26°C (remember the humidity indoors will be low, so it will feel cooler). The temperature should be checked after the air conditioner has been operating for 30 minutes. When a hot day is expected, turn on the air conditioner early rather than wait till the building becomes hot (it operates more efficiently when the outside air temperature is cooler). Keep windows and doors closed when using a refrigerative air conditioners (evaporative air conditioners require some air flow). Close curtains on hot summer and days and cold winter nights. Outdoor shading of windows in summer is most effective. If the machine has adjustable louvres, adjust them towards the ceiling when cooling, and towards the floor when heating (as cool air falls, hot air rises). Follow the manufacturer's instructions for filter cleaning.

A quick and easy rule of thumb to use for sizing an air conditioner for a room or house is the square foot method. This formula is used only for a quick approximation and is based on certain guidelines regarding insulation R values, shading, ceiling height, construction materials, windows, doors, purpose of use and occupancy. In layman's terms, 400 square feet of residential living space in a desert climate requires 1 ton of cooling capacity based on adequate insulation, 8' ceiling height and tight windows and doors. To calculate your requirement using this method divide your total square footage of living space by 400. The resulting answer is the number in tons of air conditioning capacity required.

The most important criteria to bear in mind at the time of purchasing an air conditioner are: the type of air conditioner, whether fixed or mobile, one or several units and whether it is also capable of heating by using a heat pump, cooling power, expressed in BTU/h or Watt. You may also consider: energy savings that it may provide, noise levels, which must be low, dehumidification capacity, the presence of additional functions such as: a timer for programming, "sleep" to avoid temperatures dropping too low at the night, air filtering systems, etc. Finally, you must also take into account installation costs for fixed air conditioners and periodic maintenance operations.

Generally, air conditioners can be divided into three categories: Portables are a single unit, not fixed or mounted, and can be moved from one room to the next, so-called Split Air Conditioners instead are equipped with one or more internal units fixed to the wall, and an external one. Finally there are climate control systems designed to treat the air of an entire home or building.

The average comfort range for relative humidity in a home is from 30 to 35%. When cool outdoor air enters your home, it tends to dry out as it warms up, which can cause static electricity build-up and sinus problems. A humidifier will add moisture back into the air and minimize these problems during the winter months. However the humidity level achieved in a home is effected by how tight a home is, how often the doors open and close size and style of humidifier.

No. Every system is designed to cool a certain number of square feet. By closing registers and doors in certain rooms, you disrupt and decrease the systems’ airflow and efficiency. Your system will have to work harder to cool less space, making it cycle more and become less efficient.

Is it making strange noises? Is it cooling or heating all areas of your home sufficiently? Has it been taking longer to cool down or heat up? Have your utility bills been rising for no apparent reason? Any of these are signs that you may have a problem that needs service. In most cases, the longer you delay, the worse any underlying problems will get. So be sure to contact Cooper&Hunter or your licensed installer to check out your system whenever you notice anything out of the ordinary.
