Time to understand your Air Conditioner

In summer, the most beloved appliance becomes the air conditioner. When it’s over 50 degrees in UAE and your job does not allow you to cool off by the pool with a cold drink your hand to cool you down, the air conditioner is your best friend!

How your AC works

So let us break this down into layman’s terms. Air conditioners have 2 main components: the condenser and the evap­orator. The condenser unit is usually located somewhere outside the house, probably on a concrete slab and the evaporator coil is mounted in the main duct junction.

Most central air conditioners are connected to a home’s forced-air distribution system. The hot air is moved by the blower across the cooled evaporator coil and is then delivered through ducts to cool the house. When the air conditioner works but the house doesn’t cool, the problem is probably in the distribution system.

Both the evaporator and the condenser are sealed. Therefore, a professional service person (aka MYGUY) should be called for almost any maintenance including routine cleaning. Central air conditioners should be professionally inspected and adjusted before the beginning of every cooling season.

Don’t let your maintenance end with this annual checkup. While there aren’t many repairs you can make yourself, there are specific maintenance procedures you can follow to keep your system operating at peak efficiency. Before doing any work on an air conditioning system, make sure the power to the system, both to the condenser and to the evaporator assembly, is turned off.

Lets clear up two major misconceptions
Cold air from the indoor AC doesn't come from outside

In other words, there is no air transfer between the outdoor unit and the indoor unit via the tubes connecting the units. The only transfer that takes place between the two units is heat transfer, which is different

The indoor unit does not produce cold air

The AC unit installed inside recirculates the warm air from inside the room, meaning that warm air goes into the unit which it cools and sends back into the room making the room cooler

From the beginning, understanding the function of the AC unit comes from the important principle that there is a heat transfer from a hot place to a less hot (cold) area. At the same time, the essential elements found in each of the two units of an AC are:

  • The Outdoor Unit – Compressor, Condenser, Fan, Tank for the refrigerant (Freon)
  • The Indoor Unit – Fan, Evaporator, Filter, Remote Control Elements

Refrigerant is a substance with special properties that passes from solid state to gaseous state under certain conditions, which facilities heat transfer from hot to cold. the most common type of refrigerant that you might be familiar with is Freon.

Air Conditioner Maintenance

Now, that you’ve started to get to know your AC, it’s time to show it some TLC and that you care. If you want to have a long and happy relationship together, without any mechanical issues or short life span of your AC, take into account some of our technicians’ advice


  • It is recommended that the appliance should be sanitized annually before the summer heat kicks in. In the spaces that accumulate mold and dust, it is imperative to make sure you sanitize your unit!
  • Systematic checks of the air conditioner units are always welcome. It is better to prevent minor damage than to invest in expensive recurrences when air conditioning becomes inoperable
  • Call a technician with the slightest sign of malfunction! Why should you call a technician? Doing so will save you a lot of time, money & frustration in the long run. Trying to identify the cause of a malfunction and trying to repair it yourself might cause damage to other essential components of the unit
  • Checking the Freon circuit, pressure and setting the volume required in the installations will give you the comfort of a summer season in a room with a functional air conditioner
  • Do not forget that with a sanitary air cleaning of your AC unit you will have cleaner air in your home!

You know there is something wrong when:


  • The coil is freezing up
  • The compressor is kicking on and off
  • Your AC blowing hot air
  • Your AC is tripping
  • Air is not coming & leaking
  • Your AC is taking high ampere
  • Your Electricity consumption is high
