The biggest job an air conditioner has to do is to either cool or heat the indoor air. That's not all it does though. Air conditioners monitor and regulate the air temperature via a thermostat. They also have an onboard filter that removes airborne particulates from the circulating air. Air conditioners function as dehumidifiers. Because temperature is a key component of relative humidity, reducing the temperature of a volume of humid air causes it to release a portion of its moisture. That's why there are drains near or attached to air conditioning units, and why air conditioners discharge water when they operate on humid days.
Still, the major parts of an air conditioner manage refrigerant and move air in two directions indoors and outside.
The cold side of an air conditioner contains the evaporator and a fan that blows air over the chilled coils and into the room. The hot side contains the compressor, condenser and another fan to vent hot air coming off the compressed refrigerant to the outdoors. In between the two sets of coils, there's an expansion valve. It regulates the amount of compressed liquid refrigerant moving into the evaporator. Once in the evaporator, the refrigerant experiences a pressure drop, expands and changes back into a gas. The compressor is actually a large electric pump that pressurizes the refrigerant gas as part of the process of turning it back into a liquid. There are some additional sensors, timers and valves, but the evaporator, compressor condenser and expansion valve are the main components of an air conditioner.
Bigger air conditioners work a little differently. Central air conditioners share a control thermostat with a home's heating system, and the compressor and condenser, the hot side of the unit, isn't even in the house. It's in a separate all weather housing outdoors. In very large buildings like hotels and hospitals, the exterior condensing unit is often mounted somewhere on the roof.
"I would have no hesitation in recommending the Toshiba Daiseikai for home heating. Also, although not called for too often in this country, on the odd occasion when we have held parties in our home, and the kitchen heats up too much, we put the Daisekai on cooling which works extremely well."

"Since we have had the air-con unit installed, we can either heat the conservatory or cool it at the touch of a button in a matter of minutes. We are finally able to use the room that we never could!"
Claudine Laurence, Santry
"We would be delighted to recommend Alan and the lads from Reliant Engineering for installing air-conditioning. We found them to be polite, timely, courteous, and most importantly extremely clean whilst working."
Larry & Majella Bray, Ashbourne
"Reliant Engineering installed air conditioning units in our office. Their quote was very competitive. We were delighted when the job was completed on a timely manner, with no disturbance to our business."
Lucia Poncela
"Since its installation I’ve seen a huge reduction in my gas bills, no need to have the gas heating on in the morning for the whole house, just set the AC timer to come on an hour before we get up."
Ray Pugh
"While working for us, we found the employees of Reliant very efficient and would have no hesitation in recommending the company for air-conditioning installations."
Claudine Laurence, Santry
"The staff were very efficient and completed the job quickly and smoothly. The air conditioning has been invaluable to us, improving our working conditions so much we only regret not having done it earlier. Overall, we thoroughly recommend Reliant Engineering to anyone considering to install air conditioning."
