Emergency AC repair in Lisbon: what sets us apart
💶
A written price BEFORE the technician sets off
€75 for a standalone diagnosis or €199 for the on-site repair bundle (visit + diagnosis + labour + universal parts + gas up to 300 g). You know the figure before the call ends. The usual Lisbon model is a call-out fee + €40–60/hour + parts on top — impossible to predict. With us, no surprise "extra hour" and nothing hidden at the end.
🕘
24/7, with an honest price first
Mon–Fri 9am–6pm: published rates. Out-of-hours (Saturday afternoon, Sunday, holidays, night): a written quote in 10–30 min, and the technician only sets off once you approve it (typically €220–380 + VAT depending on the time and area). Dedicated urgent line 913 805 738. No surprise surcharge at the end.
🛡️
90-day labour · 12-month parts warranty
Many local firms give just 30 days on a repair. We give 90 days on the labour and 12 months on replaced parts (new part with the maker's own warranty). If the same fault comes back within that time, we return with no call-out or labour charge.
📋
A signed technical report for a warranty claim
A clear PDF report signed by an F-Gas Cat. I certified technician: R-32/R-410A pressure readings, photos of the unit and its label, the fault code, and a plain recommendation. The kind of document you need when a new flat is still under the developer's warranty, when you're claiming on a premium brand (Daikin, Mitsubishi, LG), or for your insurer. Other firms just hand you a receipt — we give you the technical evidence.

Short-let · guests in, AC down
WhatsAppAlfama, Lisbon
Hi, this is urgent. I run a short-let flat in Alfama and my guests are already inside — the AC only blows warm air and it's a heatwave. I'm French, I don't speak Portuguese, and I'm not in Lisbon today. My cleaner has the key and can let you in. Can someone come this afternoon, before I get a bad review? Please give me the price in writing first — no surprise charge at the end.
Marie · 2:17pm
Yes — we can be in Alfama within about 90 minutes, and we'll handle everything in English. We'll arrange access with your cleaner: she lets us in, we diagnose, send you a photo of the fault and the unit, repair once you say yes in writing, and lock up. Diagnosis €75 + VAT — deducted if you go ahead. A gas top-up is from €130, or the on-site repair bundle from €199 (visit + diagnosis + labour + universal parts + gas up to 300 g included). Price in writing before we touch anything.

Technician in Alfama by 3:45pm; a universal start capacitor replaced under the €199 + VAT bundle (diagnosis included), photo + price approved by WhatsApp at 3:52pm, guests comfortable well before evening
Hi. I'm American, I work from home, and I bought a new-build flat in Parque das Nações about 18 months ago. The Daikin multi-split now shows error E4 and two units only blow warm air, but the outdoor unit keeps running. It's a heatwave and I can't work like this. I think it's still under the developer's warranty — can you come and give me a signed report (pressures, error code, photos) so I can claim it? What does Sunday cost?
Daniel · 4:44pm
Hi Daniel. For a Sunday visit we'll send the price in writing by WhatsApp within ~15 minutes (out-of-hours, typically €220–280 + VAT, confirmed before the technician sets off). New-build flats under a developer warranty are something we handle often: you get a clear PDF report from an F-Gas Cat. I certified technician — the E4 code explained, the real R-32 high/low pressure readings, photos of the label and the install, and a plain recommendation. You attach that to your claim so the developer has to honour the warranty. The report is yours to keep. Want us to send the written quote?

VentoFix · 5:08pm
Technician on site by 7:30pm; report confirmed the E4 fault + a leak on the outdoor coil → the developer accepted the warranty claim within 11 days
Morning. I'm British and I let a flat in Arroios long-term. My tenant has just messaged that the AC is completely dead in this heatwave and wants it sorted today. I'm not always in Lisbon, so can you arrange access directly with the tenant? I need a clear price before any work, and a proper fatura with my NIF for my accounts.
Stephen · 8:30am
Morning Stephen. No problem — we'll contact your tenant directly to agree a time and get access today, and keep you copied in. We diagnose on site and send you the full price in writing before doing anything: diagnosis €75 + VAT, or the on-site repair bundle from €199 (visit + diagnosis + labour + universal parts + gas up to 300 g). If a control board or compressor is needed, we quote that separately first (typically €230–720). Once you approve, we fix it and email you a proper fatura with your NIF.

VentoFix · 8:38am
Technician met the tenant the same afternoon; a blocked drain + worn fan motor fixed under the €199 + VAT bundle (price approved in writing first), fatura with Stephen's NIF emailed that evening for his accounts
Good evening, I am sorry it is late. I am German, I live alone in Cascais. My air conditioning smells like something burning and it blows warm air. It is very hot and I do not sleep well. I worry a little about being overcharged because I am a foreigner. Can someone reliable come tonight or early tomorrow? Please tell me the price first, in English. I pay by bank transfer and I need the invoice by email.
Brigitta · 10:14pm
Good evening Brigitta. A burnt smell is an electrical risk — please switch off the breaker for the AC tonight, just to be safe. You have two options: (a) tonight, out-of-hours: we send the price in writing by WhatsApp in ~15 min, typically €220–380 + VAT; or (b) Saturday 9am, business hours: diagnosis €75, or the on-site repair from €199 if it's a universal part. The technician will speak slowly and clearly, find the cause (often the control board or the indoor fan), and explain everything and the price before touching anything — a fixed figure you agree first, no surprises. We email the fatura (UK or PT NIF) and you pay by bank transfer or MB Way, no rush. Which would you prefer?
Saturday morning business hours: on-site repair from €199 + VAT (or €75 standalone if you decline) · tonight out-of-hours: €220–380 + VAT, quoted in writing first · fatura by email (UK/PT NIF), bank transfer accepted

Repair or replace? An honest call by the age of your AC
Before you pay for an expensive repair on an old unit, see what actually makes sense. The honest line: the HVAC rule of thumb is 50% (if the part costs more than half a new unit → replace). For an AC over 10 years old we use a stricter 30–40% (age-adjusted, no commission).

An AC under 5 years old is almost always worth repairing. In a new-build flat, check the developer's warranty (typically 5 years) before paying — a signed technical report helps you claim it.

Compare the SEER: a 6–10-year-old unit sits around SEER 4.2; a new R-32 inverter reaches SEER 6.5–8.5 (mid-premium tier). Replacing it cuts the summer electricity bill by around 30–40%.

An AC 11+ years old: SEER 3.5–4.2 (vs 6.5–8.5 new). Every expensive fault is a sign it's near the end. Replacing it saves around 35–50% on the yearly electricity bill.

Efficiency (technology, not the gas)
Typical pre-2018 on/off: SEER 3.5–4.5
Current R-32 inverter: SEER 6.5–8.5
+40–80% a year
EU Regulation 517/2014 + 2024/573: R-410A is being phased down. From 2032 only recycled/reclaimed refrigerant will be available. Typical pre-2018 R-410A systems are on/off units at SEER 3.5–4.5 (the technology, not the gas, drives efficiency) — switching to an R-32 inverter combines the refrigerant sunset with a jump to SEER 6.5–8.5. An R-410A unit with recurring leaks stops being viable.

I PDF report), landlords coordinating access with their tenant, heat pumps for DHW / air-to-water / pool (Atlantic, Ariston, Daikin Altherma, Bosch, Vaillant), and overseas owners and family abroad (fatura with a UK/CH/FR/DE NIF, international transfer).
Emergency AC repair in Lisbon: common questions
Usually the same day, or next morning at the latest. In a heatwave we prioritise people with no cold air. In central Lisbon (Príncipe Real, Estrela, Campo de Ourique, Arroios, Alvalade, Alfama, Baixa) a technician is typically with you in 60–180 minutes on a weekday; for the surrounding areas (Parque das Nações, Oeiras, the Cascais–Estoril line) allow a little longer. Call or WhatsApp and we'll confirm a real arrival window.
Yes — from the first message to the written quote and the final fatura. You'll always know what's wrong and what it will cost, in plain English. Many of our customers are relocated professionals, landlords, short-let hosts and retirees who don't speak Portuguese.
On-site diagnosis is a fixed €75 + VAT during business hours. If you accept the repair on the spot, the €75 is deducted in full from the total. A common on-site repair (visit + diagnosis + labour + universal parts + gas up to 300 g) is from €199 + VAT. You see the price in writing before any work — no surprise hourly charges or hidden parts at the end.
The most common causes are low refrigerant (a small leak), a tired capacitor or fan, a blocked drain, or a sensor or control fault. We diagnose it on site, show you what we found, and tell you the price before touching anything. A gas top-up is from €130 + VAT; most other faults are covered by the €199 + VAT on-site repair.
Yes. Our van carries the universal electrical and mechanical parts and R-32 / R-410A gas, so most repairs are finished on the same visit — that's what the €199 + VAT bundle covers. Only large items (a control board, a big motor or a compressor) are ordered from the maker; we quote those separately in writing and fit them as soon as the part arrives.
Yes — this is routine for us. Give us your tenant's, guest's or cleaner's contact and we coordinate entry directly with them, diagnose the fault, send you photos and the written price, and only proceed once you approve. You don't need to be there.
That's a big part of what we do for overseas owners. Send us the address and a local contact (key-holder, cleaner or manager); we arrange access, fix it, send photos and the price in writing, and you pay by bank transfer (IBAN PT) or MB Way. We email a proper fatura with your NIF — including a foreign NIF (UK, CH, FR, DE) where needed.
Mon–Fri 9am–6pm we use published rates (diagnosis €75, on-site repair from €199, gas from €130, all + VAT). Out-of-hours (Saturday afternoon, Sunday, public holidays, night) is typically €220–380 + VAT depending on the time, day and area. We always send the price in writing first and the technician only sets off once you approve it — no surprise mark-up at the end.
Yes. Every job comes with an official Portuguese fatura showing your NIF — useful for your accountant, your tax return and your rental accounts. We accept a foreign NIF too. Payment by MB Way or bank transfer (IBAN PT).
In most Lisbon apartments, yes — we work safely from balconies, light-wells and shared façades. If the building has a protected façade or the condominium needs to approve external access, we won't touch the exterior without that permission, and we'll tell you up front what's needed.
We repair heat pumps from every brand — Atlantic, Ariston (DHW cylinders), Daikin Altherma, Bosch Compress, Vaillant aroTHERM (air-to-water) and pool equipment. Heat-pump diagnosis is €95 + VAT (deducted if you go ahead). A typical DHW repair is €120–190; air-to-water compressors and boards are quoted after the on-site diagnosis. Warranty: 90 days labour · 12 months on replaced parts.
