FACTS

• The typical central air conditioning system is a split system, with an outdoor air conditioning, and an indoor coil.
• Using electricity as its power source, the compressor pumps refrigerant through the system to gather heat and moisture from indoors and remove it from the home.
• Heat and moisture are removed from the home when warm air from inside the home is blown over the cooled indoor coil. The heat in the air transfers to the coil, thereby "cooling" the air.
• The heat that has transferred to the outdoor coil is then "pumped" to the exterior of the home, while the cooled air is pumped back inside, helping to maintain a comfortable indoor temperature.
  

What can I do before calling someone to service my system?

HVAC systems are complicated networks of machinery that should be serviced by a certified professional. However, if your HVAC system seems to be malfunctioning, you can try a few basic steps, which may correct your problem, prior to calling a service professional. If you do not feel comfortable performing any of these tasks, however, do not hesitate to call us.

• Disconnect and reconnect your indoor and outdoor switches.
• Make sure your circuit breakers are in the ON position.
• Make sure your filters are clean.
• Check air supply and air return and make sure they are unobstructed.
• Check the settings on your thermostat.
• Make sure the system switch is on the appropriate COOL setting.

How long will my system last?
Proper maintenance is key

• Maintenance and service play a key role in the lifecycle of a cooling air conditioning system. If all recommended maintenance and service actions are taken, an air conditioner can last 15 to 20 years.

What is the key of installation?

• The location for the indoor unit:
  
  
• The cool air can not directly blow to the bed.
• Keep the air outlet clear of any obstacle so that outgoing air flows smoothly in the entire room.
• Keep the air inlet clear of obstacles that could block the incoming air.
• Provide sufficient space on both sides and above the unit,
• Keep TV set, Radio and the like 1M or more away from the unit and the remote control.
  
  
• The location for the outdoor unit:
  
  
• Place the outdoor unit on a stable base.
• Provided the sufficient space around the unit, It should also be well ventilated.
• The unit should not be exposed to strong wind nor splashed with rain water.
• Avoid locations exposed to machine oil vapor, salty air (facing the seashore, for example), hot spring vapor sulfur gas.
  Such location can cause breakdown.
• Also, avoid locations exposed to muddy water(along a road, for example) or where the unit can be tampered with.
• Select a location where the outgoing air or operating noise cannot annoy other.
• Install the unit on a stable base not to allow louder noise.
• Keep the air outlet opening free of any obstacle. This could affect the performance of the unit and create loud noises.
  
  
• Make sure the electrical power switch is located near the outdoor unit. And the capacity is enough for the machine.
• Make sure all the installation material are qualify and thickness enough e.g. the copper tube is, heat insulation; electrical wire;
  PVC drain pipe.
• Make sure all the copper tube and PVC drain pipe are cover with heat insulation properly.
• Make sure the copper tubes are not damaged at all the bend point, and they are lay properly and the heat insulation is
  not very tight.
• Make sure the refrigerant system have been vacuum by vacuum pump.

How do I determine the size, or capacity, of my air condition system?

• What is the location of your home? Is the sunshine from the morning to evening?
• The number of window in your room. The direction your home faces.
• The number of door in your room. The direction your door faces.
• The number of heat-producing appliances in your room.
• the number of people that live in your residence
• A RichOcean professional can perform the proper calculations to determine the appropriate cooling unit for your home and lifestyle.

Technical Note:

BTU : (British Thermal Unit)
– The amount of energy that’s needed to change the temperature of one pound of water by one degree Fahrenheit. This is what the heat removed from your home is measured in.

Horsepower:
One horsepower equal to 9,000 BTU/hr (check with your contractors exactly how many BTU/hr when they quote in horsepower) ; Cooling capacity: 1kw/hr = 3.414Btu/hr

Fan Coil:
The air conditioner unit that is installed inside the house. It takes the heat and moisture out of the air as the refrigerant (what you might know as gas) evaporate.

Refrigerant:
This is the real name for what many people call gas. It’s the fluid that evaporates at low temperatures and pulls heat and humidity out of the air.

Condenser:
This is the unit outside the house that’s usually making all the noise (at least in the older models). This holds the compressor that is called the heard of your system. In addition it also transforms your refrigerant (gas) from a gas to a liquid. Finally there’s a fan discharging heat to the outdoors.

Compressor:
The heard of your air conditioner. It move the refrigerant from the condensing unit to the fan coil unit and back to the condensing to form a cycle.
