You are going to learn DIY air conditioner installation, so that our house will be a real paradise, despite the heat.
We will place two devices, a pump on the outside and a diffuser inside the house, which we will connect to each other and we will also put a drain to avoid condensation. Taking into account the surface of the room or rooms that we want to air condition, we will choose the model of air conditioning that best suits our needs.
We have opted for a model that is divided into two units. The most voluminous device contains the compressor and the condenser that we will install it on the outside of the house. The smallest one is composed of the evaporator, the fan, the air filter and the control system that we will place it inside the house.
We will connect the two units using two copper tubes, one of them will conduct the refrigerant liquid and the other the gas; It is a round trip circuit. The refrigerant that goes from the external device to the interior absorbs the heat of the room and evaporates; after traversing the cooling circuit to the outdoor unit, it is transformed back into liquid, and the warm air is discharged.
To pass the pipe from the inside to the outside of the house, we will drill a hole in the wall. This model also has a heat pump, so in addition to producing cold, you can also heat a room, expelling cold air outside.

Step by step to DIY air conditioner installation :
Once we have chosen the place where we will place the internal unit, we will check that in the area there are no pipes or cables that we can damage when drilling, with the metal detector.
Next, we will present the support on the wall, level and mark the fixing points with a pencil.
Drill the holes with the drill, drill for concrete of the same diameter as the dowels and screws that we are going to use to hold the support; in our case 6 mm.
With the help of a hammer, we introduce the expansion blocks.
We replace the bit with the appropriate tip and fix the plate to the wall with some screws that the kit already includes.
Now we will have to make a through hole for 65 mm next to the support, as the manufacturer tells us, to remove the connection tubes to the outside; so we draw with a pencil a circle of that diameter using a piece of tube as a template.
With the drill provided with an extra-long drill of 22 mm, we will make the hole. We are going to place the indoor unit higher than the outdoor unit, so we will make the hole with a slight downward slope, to favor the drainage of the condensation.
After emptying the circle with the drill and the bit, we will finish the work with the help of a hammer and chisel.
To channel the pipes and the electric cable to the outside more easily, we will introduce in the hole a PVC tube of length equivalent to the thickness of the wall and with a diameter adaptable to the hole we have made.
Next, we will pass the electric cable and the cooling and drainage pipes through the PVC pipe.
Place the indoor unit on the stand so that it is firmly held by the hooks on the plate.
Once we have placed the indoor unit, we will proceed to install the outdoor unit. The first thing we will do is put a gutter on the facade of our house, to hide the cable and tubes. To do this, drill holes with the drill and drill for concrete of the same diameter as the dowels and screws that we will use to fix it.
After joining the studs with the screws, insert them into the holes with a hammer.
Then, screw them definitively with the drill bit provided with the appropriate tip.
To join the tubes to the external device, we will have to make some extensions. To do this, we will flare or enlarge the ends of the copper tubes with the help of a flare, a tool used by plumbers.
Next, we will have to make a siphon in the suction tube to avoid liquid returns to the compressor at the stops. To carry out this work, we will use a pipe twister; It is not advisable to bend the tube with your hands, as it could clog.
When we have shaped the tube, we screw it into the gas conduit by tightening the nut with the help of two keys. In the same way, we will connect the other copper tube to the coolant conduit.
After splicing the pipes, line them with an insulating hose to protect them from changes in temperature and rain.
Introduce the electric cable and the two tubes in the gutter and put the lid on.
Now we will make the joints of the pipes in the outdoor unit, by screwing the nut first with the hand and then pressing hard with the two keys.
Also make the electrical connections, introducing each pole in its corresponding terminal and tighten the screws with the help of the electric screwdriver. Check the firmness of the fixation.
Once the refrigerant and electrical connections have been made, we will purge the tubes, that is to say, empty them of air so that the coolant can circulate without any problem.
Finally, seal the plastic tube with polyurethane foam so that there are no leaks and check that the installation works correctly. When using this product, take in mind that the volume of the foam increases considerably since it is applied until it hardens completely.
Now it can be hot! We are already prepared for the summer; With the installation of air conditioning that we have taught you to perform, we will keep our home at the ideal temperature, even on the hottest summer days.
