How can I fix my broken air conditioner and why is it no longer cold?
In these times of extreme heat, purchasing air conditioning is a reflex for many of us. This device has a number of mechanically impressive technologies that ensure uniform and nearly immediate freshness. Therefore, it is usual to see malfunctions and home ac repair which can rapidly turn into hot subjects if they occur in the thick of the summer.

Air conditioning that is not cold: solutions to avoid heatstroke
Does your air conditioner refuse to get cold? Rather annoying when the heat wave is in full swing, putting the nerves to the test.
Relatively quick to diagnose, the problem is not always very complex to solve. The outcome is usually simple and binary: you get there with a few gestures, or the intervention of a professional is mandatory. Explanations.
1. Try reprogramming
This is the very first reflex to have!
Devices equipped with digital microprocessors can sometimes change configuration unexpectedly. A power outage in your home may also have forced a reset of your air conditioning, or someone you know may have changed your usual temperature… It may also be that a delayed cycle is programmed, or that the economy mode of your energy is a little too stingy with freshness.

2. Check its power supply
Technologies evolve at a considerable speed! This is not without optimizing all aspects of the machines, including their noise emissions.
If you quickly get used to a silent device on a daily basis, you may not realize when it is on, off… or even broken down! Especially when it is programmed and lives “at its own pace”.
Pay attention to the sound it produces. If this is zero, and the device is not supposed to be off, it may no longer be powered. This failure can come from a fuse or from your electrical panel. A cable can also be cut in one place, in which case detection may be more complex if your electrical installation is embedded.
On the other hand, the control of the internal electrical circuit will be the responsibility of a qualified professional.
3. Make sure your home is ready to cool
Let’s explain. Although the air conditioner is a very powerful device, it does not work miracles without a little help.
In this sense, know that your home must be perfectly insulated and airtight to air inlets from the outside. Heat should therefore not penetrate through doors or windows, especially if they are only equipped with single glazing. So be sure to close all the openings in your home, then try to run your air conditioner again.

4. Clean its filters
The maintenance of an air conditioning unit is more than essential. It guarantees, in fact, maintenance in good condition over time and also ensures the good health of the occupants of a dwelling.
Dirty mechanical filters can explain the lack of fresh air coming out of an air conditioner. By altering the cleanliness of the components, dust or mold can seriously prevent the air from circulating. The result is unequivocal: bad odors appear, and your level of comfort drops! Cleaning the filters, therefore, makes it possible, and very often, to restore all its vigor to an air conditioner; for that :
- Open or remove the cover,
- Take out the air filters,
- Vacuum the dust present on the surface of the filters,
- Clean them if necessary with slightly soapy water,
- Reassemble the assembly after they have completely dried.
5. Check compressor status
The production of lukewarm air is symptomatic of a faulty compressor.
If its thermal protection no longer works or works badly, it risks operating under undercurrent or overheating. If the compressor is noisy, it could be that it lacks oil, or, on the contrary, that the latter is excessive. The nozzle and regulator may also require replacement.
Finally, if it does not start at all, the phase controller may have tripped.
6. Contact a professional
Even if their design avoids it as much as possible, some devices can be victims of refrigerant gas leaks. Particularly harmful, the latter must be handled with care.
Do not run any risk and contact a professional to carry out the necessary checks and replacements.
The latter will also be the only one able to check the condition of the belts, and the possible presence of a plug or frost on the exchangers. He can also check the condition of the pressure switches or the calibration of the protection.

Why is my air conditioner no longer cooling? 4 possible causes
Your favorite device is no longer doing its job? Discover without detour the four most probable causes of this problem, to judge coldly… and act hot!
1. He is deprogrammed
Have you recently entrusted the remote control to a guest who is not very familiar with your device? A storm (probably, in summer!) caused a power outage in your home? Have you activated the “economy” mode to reduce the impact on your electricity bill?
Anyway, a change in your air conditioning programming can have an immediate result! Check the ambient temperature and also check that the one requested is not too high: a turn in the parameters would not be too much.
2. He has an electrical problem
This is a very common concern. Electricity is at the heart of our homes and appliances, and they are the first to suffer when it experiences a moment of weakness.
The failure can then be external ( circuit breaker, embedded cable, etc.) or internal to the air conditioner (electronic card, motor power supply, etc.).
3. Its filters are clogged
Reversible or not, any device can experience a drop in performance when it is dirty or clogged. Everyday life often means that we neglect the maintenance of household electronic or mechanical devices, although their capacities depend on it.
Just as we regularly empty a vacuum cleaner, or defrost a refrigerator, it is recommended to maintain the filters of an air conditioner periodically, so that it produces as much cold as when it started!
Poorly maintained filters can quickly create temperature problems.
4. An internal component is faulty
Air conditioners are in high demand when running at full capacity throughout the summer season.
These sometimes very expensive investments are optimized to last over time, however, their aging is inevitable, thus coming with a lot of small inconveniences; the compressor or the gas circuit may be damaged, and the pressure switches or components of the electronic board require replacement… This is somewhat normal, but it is better to confront it as late as possible.
To conclude, know that the installation of air conditioning should not be carried out lightly. It is essential that the commissioning is successful, to guarantee an optimal result. In concrete terms, this means that the tightness of the circuit must be checked with pressurized nitrogen or that the flare nuts of the device must be tightened with a torque wrench. Finally, an additional charge must be provided for long circuits… Scales and fine adjustments that only an authorized technician will be able to perform!
