After connecting the copper pipes between the indoor and outdoor units, a deep vacuum must be created in the refrigeration circuit to eliminate air and moisture before charging the gas. Without a vacuum, residual air mixed with the refrigerant gas reduces equipment efficiency by 20-30 percent, overheats the compressor, and drastically shortens its lifespan. The correct vacuum is achieved with a specific pump that lowers the pressure to -700 millibars and is maintained for 30 minutes to verify its seal. Mitsubishi Electric, Daikin, and LG are the three premium brands we install most often. Their inverter technology is very mature and they consume 40 percent less than old fixed air conditioners to produce the same cooling. Their outdoor noise level is clearly lower, which is important in shared courtyards where neighbours might complain. Their filters are of better quality and last longer between cleanings. When an air conditioner stops cooling as effectively as before, the possible causes are various and at first glance seem identical. The difference lies in the speed and nature of the failure. If the air conditioner has gradually lost efficiency over months, a slow gas leak is most likely, reducing the available amount in the circuit until it malfunctions. If the air conditioner was cooling normally and suddenly stops providing cold from one day to the next, it is usually a large leak, compressor failure, or a problem with the electronic board. If it starts but stops after a few minutes with an error message on the remote, it could be the thermostat, a temperature sensor, or a communication issue between units.

Official manufacturer warranty (3-5 years) plus our 30-day labour coverage. Toshiba, Panasonic, and Fujitsu are a step below in price but not too far behind in quality. They are a good option for tight budgets. More economical brands like basic Samsung, Hisense, or Hitachi function correctly for the first four or five years, but their efficiency and durability are lower and they usually require more maintenance. The second detail is the gas charge. The quantity must be exactly as indicated by the manufacturer for the installed copper length. You won't notice a gram more or less immediately, but accumulated over 5 years, it translates into a loss of performance. The charge is always done with a precision electronic scale, not by estimating pressure as some quick installers do.

The price for a gas recharge in El Guinardó typically ranges between €126 and €1602. The final figure depends on the property's condition, materials, and working time.
