Heatwave in Lisbon? We deliver an AC today.

Quick answer: during a heatwave in Lisbon, AC Rental Lisbon delivers a portable air conditioner the same day (if confirmed before 4pm), with no installation and no price hike at peak — €40/day or €210/week. Book on WhatsApp, ideally the day before, as stock sells out within 24–48h.

How it works during a heatwave

1. Contact us on WhatsApp (fastest). Tell us your neighbourhood and how many days you need.
2. We confirm availability within 5 minutes. During extreme heatwaves we may have to put you on a waiting list of a few hours.
3. We deliver the same day if confirmed before 4pm. We set it up in your flat — window kit included.
4. Use it as long as you need — 1 day, 1 week, 1 month. Let us know when to collect.

Why stock sells out during heatwaves

During IPMA red alerts (usually 2–4 days per summer), requests rise 400% compared to a normal day. The units available in Lisbon sell out within 24–48h. Those who wait are left without an AC.

Our recommendation: if you see a heatwave forecast on IPMA, contact us the day before. We'll reserve the unit for you.

Prices during heatwaves

The same as always. We don't raise prices at peak. €40/day, €210/week, delivery included, ready to use.

Only in extreme cases (Caparica, Sintra) do we charge an additional travel fee of €5–8.

What to do while you wait for the AC

If delivery will take 1–2 hours, there are immediate tricks that cut 3–5 °C:

• Close blinds/shutters on south- or west-facing windows
• Create a cross-draught between the kitchen and bedroom
• Take a lukewarm shower (not cold — counterintuitive but more effective)
• Drink water every hour, even if you're not thirsty

Signs you really need an AC (don't wait any longer)

• You have at home: an elderly person, a baby, someone with cardiovascular disease
• You work from home and the heat is stopping you from working
• You've slept badly for more than 2 nights in a row
• A flat in the historic centre (Alfama, Mouraria) facing south
• An Airbnb host with a check-in today/tomorrow and guests who will complain

For Alfama, Mouraria, Bairro Alto, Baixa

These neighbourhoods fall within a classified historic centre — fixed splits are forbidden. A rental portable AC is the only legal option. During heatwaves it's also the only fast option (installing a split would take 2–4 weeks even if it were legal).

Tourist flats / Airbnb
