The first step is always a preliminary visit. We measure the exact length of copper piping between the indoor and outdoor units and check the available space for the outdoor unit and its orientation. We also assess whether the electrical panel has sufficient capacity for the new unit's consumption or if the contracted power needs to be increased, and we verify community regulations regarding facade installations. Without measuring the copper, checking the facade, and evaluating the electrical panel, we cannot provide an honest quote. Free, no-obligation visit.

After connecting the copper pipes between the indoor and outdoor units, a deep vacuum must be created in the refrigeration circuit to remove air and moisture before charging the gas. Without a vacuum, residual air mixed with refrigerant gas reduces the unit's efficiency by 20-30 percent, overheats the compressor, and drastically shortens its lifespan. The correct vacuum is created with a specific pump that lowers the pressure to -700 millibars and is maintained for 30 minutes to verify airtightness. Commercial units operate under much more demanding conditions than domestic ones. 12-14 hours of daily operation during peak season, variable thermal loads throughout the day, accumulated dirt from higher airflow. Without adequate maintenance, a breakdown during the season for a commercial establishment costs not only the repair but also lost revenue from hours or days of service interruption. Certified units, installation with a certificate (boletín) and industrial registration where applicable.

The second detail is the gas charge. The amount must be exactly as indicated by the manufacturer for the installed copper length. One gram more or less won't be noticeable immediately, but accumulated over 5 years, it translates to a loss of performance. The charge is always done with a precision electronic scale, not estimated by pressure as some quick installers do. Toshiba, Panasonic, and Fujitsu are a step below in price but not significantly in quality. They are a good option for tighter budgets. More economical brands like Samsung, basic Hisense, or Hitachi function correctly for the first four or five years, but their efficiency and durability are lower, and they tend to require more maintenance. Yes, it is mandatory in Spain for any handling of refrigerant gas. Without it, the manufacturer's warranty is void, and the installation may be declared illegal.
