The first step is always a prior visit. We measure the exact copper pipe distance between the indoor and outdoor units and check the available space for the outdoor unit and its orientation. We also assess whether the electrical board has enough capacity for the new equipment's consumption or if the contracted power needs to be increased, and we verify the community's regulations on facade installations. Without measuring the copper, checking the facade, and evaluating the electrical board, 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 the refrigerant gas reduces the equipment's efficiency by 20-30%, 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 tightness. Commercial equipment operates under much more demanding conditions than domestic units. 12-14 hours of daily operation during peak season, variable thermal loads throughout the day, accumulated dirt from higher airflow. Without proper maintenance, a breakdown during the season for a commercial establishment results not only in repair costs but also in lost revenue from hours or days of service interruption. Certified equipment, installation with an official report (boletín), and industrial registration where applicable.

The second detail is the gas refill. The amount must be exactly as indicated by the manufacturer for the installed copper pipe length. A gram more or less won't be noticeable immediately, but accumulated over 5 years, it translates into a loss of performance. The refill is always done with an electronic precision 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 basic Samsung, 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 voided, and the installation may be declared illegal.

The price for a gas refill in Hostafrancs typically ranges between €126 and €1602. The final figure depends on the property's condition, materials, and work time.
