Air Conditioning Repair Guide

When it comes to air conditioning or air conditioning systems, the best way to determine that you need a repair or replacement of any of its components is to contact an air conditioning and air conditioning professional. This is especially important if you are not familiar with the complex operation of air conditioning.

To determine the, or problems, and need to repair your equipment, you should seek advice and help from people who are actually trained for this job.

That said, however; there are some signs that can reveal to you easily and quickly that something is not right in one of your units. If you experience any of the following signs or symptoms, you should contact an air conditioning repair service immediately.

Symptoms to consider for air conditioning repair

Symptoms to consider for air conditioning repair

  • If your HVAC system does not turn on, it’s time to contact a repair service. (However, it is advisable that you first look at your switches on the electrical panel to make sure that you have not jumped a fuse).
  • If your A/C unit does not pour out or produce cold air but is nevertheless pouring air at room temperature or hot air, then you should turn it off immediately and contact a qualified A/A repair technician, otherwise, it could cause major illnesses and extra expense on repairs.
  • If your air conditioning system starts leaking water through one of the units, both outside and inside, then you should contact an air conditioning service immediately.
  • If your air conditioning equipment has a large buildup of ice inside or around the unit or pipes that is not normal, you should immediately contact an air conditioning repair service.
  • If your air conditioning system smells bad (e.g. plumbing), you should contact an air conditioning repair service immediately.

These are just some of the most common symptoms and signs that are good indicators that something is wrong with your air conditioning system.

You should NEVER attempt to disassemble or repair the unit on your own, you must first disconnect your AIR unit from the electric current and then call a teacher to the trained person in order to ensure that the unit is not damaged or cause personal injury.


Risks of making an Air Conditioning Repair ourselves

Aside from the risk of personal injury or excessive damage to the unit, one of the biggest dangers of making a repair yourself is the extra cost it can entail.

Most people who try to do an air conditioner repair of their own free will actually end up paying double or triple the cost they would pay if they simply turned to a trained professional.

A trained professional knows how to accurately repair your air conditioning equipment so it can save you hundreds of euros. In addition, most air conditioning repair services receive special discounts on parts that you would be unable to purchase on your own. Therefore, it is always more advisable to seek the services of a trained professional.

Also, 85% of people who do, or try to do, their own A/C repair will most likely have to repair their unit again within a few months.

If you have no experience in repairing air conditioning or air conditioning equipment do not get down to business and contact an authorized professional, otherwise, you will simply be making a Band-Aid on your device in a fracture that needs the help of a professional.


Causes of a possible breakdown of the Air Conditioner 

Causes of a possible breakdown of the Air Conditioner 

We can always observe the symptoms and determine a possible breakdown, but I insist, if you do not have enough knowledge it is better to call technical service. However, the instructions below are sure to help you, especially to prevent future breakdowns.

In the air conditioning, as in many appliances, the possible breakdowns are multiple and the first thing we have to observe first of all is the type of breakdown that our air conditioning has, but today we will focus on 5 breakdowns of the refrigerator circuit and the air conditioning repair.


Lack of refrigerant

The first symptom of the lack of gas in our air conditioner is that it does not cool or does not heat enough, or at least does not do so as in the beginning, and if we go to the outdoor unit and touch the connecting nuts (high and low) we will clearly see that the 2 nuts are warm or hot (this depends on the lack of refrigerant you have) in addition to checking that the air that expels the fan is at temperature Environment.

If you have a pressure gauge, the first thing we will notice is that the pressure in both the high and low areas is low (for both the heat and cold cycle), and if we check the electrical consumption with an amperometric clamp we will see that the electricity consumption is also lower than normal.

Well, to carry out the air conditioning repair we need to put a load of gas (obviously) and it will be best, if we do not have sufficient means or knowledge, to call the technical service of our air conditioner.


Obstruction of the capillary or expansion valve

This breakdown is usually not very common if the installer did its job well, since these parts are normally clogged by impurities in the circuit, or by moisture because it has not made a good vacuum. This moisture freezes and creates an ice cap.

Symptoms include:

Low pressure in the low area, high pressure in the thigh area but initially (after a while it would be low as well) and low power consumption. In heating mode, it would be high pressure in the low area initially and then staying low, low pressure in high and low power consumption.

The air conditioning repair to be carried out would be to collect the coolant, replace the expander element (either capillary or valve), make a good vacuum and reload the circuit.

To do all this it would be best to call technical service unless you have the means to perform the repair.


Dirty filters or inner exchanger

This breakdown is the most common in the air conditioning and by which many people call the technical service desperate, without being aware that this happens because it does not bring very simple maintenance to our air conditioner, cleaning filters.

Symptoms include:

Low pressure, high pressure and low power consumption.


Dirty outer exchanger

This breakdown is because of what we said in the previous one, poor maintenance of our air conditioner, the only thing that instead of being the indoor unit is the outside that is dirty, and the symptoms are:

Low high pressure, high pressure and high power consumption


Four-way valve bypass

This usually happens because the valve piston has been caught and does not go either way or to the other, sometimes giving it a few locks with a screwdriver or a wrench is usually released because if our air conditioning machine usually walks a lot in one mode, for example cold, the piston never moves and gets stuck.

On the other hand, the bovine (or solenoid) may be damaged or may not have electric current reached by a variety of causes.

If the problem is the piston, the four-way valve will have to be replaced, if it is the bovine valve, it will have to be replaced or verified why no current arrives, which may be due to a failure of the electronic board or because the cable is in bad condition.

The most common symptoms of this fault can be seen by touching all 4 valve tubes. 2 of them always have to go cold and the other two hot, if for whatever it is, some or some, they are temperate we will know that something is not right.

If we put our pressure gauge high and low we will see that the pressures are abnormal, reaching fluctuations. Electricity consumption will surely be lower than normal.

This is a somewhat more complex air conditioning repair.



Coming this far, to tell you that many times in the air conditioning, and in the air conditioning in general, we can find totally different breakdowns but with the same symptoms, I want to say that you do not have to take everything to the letter, since in a refrigerator circuit can pass a thousand things, such as a high-strangled pipe, when there is strangulation there is an expansion, drastically lowering the pressure.

So I hope this air conditioning repair guide has helped them but they always check things at their discretion and professionalism.

If you liked the article I hope you share it, I will thank you very much so there will be more people who can do air conditioning repair.
