How to prepare a ventilation project
Review how rooms are used and what routes are available before choosing a system.
Describe what you observe
Note the rooms and times when you notice a problem: after showering, during cooking or when a home has been closed. Photos and a precise description help focus the discussion. A damp mark alone does not establish its cause.
Record existing features without changing them
List visible vents, grilles, equipment and known ducts. Do not block openings or dismantle the system to prepare for a visit. Mention combustion appliances so a professional can assess interactions.
- A room plan and daily uses
- Existing equipment and openings
- Access to ceilings, ducts and shared spaces
Ask for an understandable proposal
Request the rooms covered, intended routes, building work, settings and maintenance tasks. Ask about noise and filter access. In a shared building, check the required permissions before planning changes to common areas.
Air conditioning & ventilation: complete guide (Spain)
In Spain, well-designed AC genuinely improves daily life: summer comfort, sleep, remote work, kids, rentals. The real lever is matching your home (area, exposure, insulation) and your usage.
Then we validate what truly changes outcomes: unit placement, airflow quality, condensate drainage, line length, electrical supply and neighbour-side noise.
Maintenance: prevent breakdowns and keep performance
In hot, dusty areas, filters clog quickly: a common cause of odors, higher bills and lower performance. Regular maintenance extends lifespan and reduces summer breakdowns.
Describe symptoms and everyday use
Before the visit, note where and when you notice condensation, persistent odours or stuffy air: after a shower, while cooking, in the morning or when the home has been closed. These observations help explain how the home is used; they do not establish the cause. Damp marks may also need a leak investigation or a building inspection.
Prepare photographs of grilles, air inlets and affected rooms. Mention replacement windows or renovations that changed the movement of air between rooms. This helps the professional assess the air path through the whole home.
Compare the complete system in each quote
Ask which rooms are covered, where air will enter and leave, and which ducts or openings need checking. The proposal should specify equipment, drilling, connections, finishing work and maintenance access. If a shared area or façade is involved, confirm permissions before scheduling work.
Discuss noise as well: the position of the equipment, sound reaching other rooms and expected operation at night. Two quotes are comparable only when they cover the same requirements and work.
Plan for maintenance from the start
Ask for a demonstration of the controls and an explanation of the parts the user can access. Request the manufacturer’s recommended maintenance tasks and intervals. Keep model references and instructions with the quote. The choice should account for future access to filters, vents and components that need professional attention.
