Air conditioning servicing on the Silver Coast
English-speaking AC servicing for the people who own homes here: part-year owners who arrive to a damp, musty house, relocators who renovated an older place, settled retirees, and small holiday-let hosts.

Renovated house, keep the warranty

Hello. We renovated an older house near Caldas and put AC in during the works (LG split, 1 outdoor + 2 indoor). It’s been in about a year and never serviced. We’d like a full service with a report that keeps the LG warranty valid, and we want it kept working for winter heating too. A Saturday morning would suit. What’s the price, and can we have a fatura with our NIF?
Gavin & Sue · 11:22
Yes, of course. We do a full service with a report that keeps your manufacturer warranty registered: high/low pressure readings, gas charge, photos of the indoor and outdoor labels, air-output temperature in both cooling and heating, and the state of the filters and coil. Saturday mornings 9–12 are available. A one-off service is €85 per unit (2 units = €170 + VAT), including a signed PDF report by an F-Gas Cat. I technician, and a fatura with your NIF. If you’d like it kept up yearly, the Annual Pro is €149/unit/year.

Hi, I have two holiday cottages I let, one near Óbidos and one near Nazaré, each with AC. Guests mentioned a smell and weak cooling last summer. I’d like both serviced reliably, ideally one arrangement with access sorted between bookings and a single invoice, and a photo per unit I can use on the listing. I’m not always local. Can you do that?
Niamh · 14:05
Yes, that’s straightforward. For two cottages, the Annual Pro is €149 per unit/year with two visits (spring before the season + autumn after), an anti-mould treatment (important in the damp coastal air) and 4h priority. We arrange key access with whoever you use locally, and email a clean photo of each unit you can put on the listing. One invoice with your NIF. With one AC per cottage that’s 2 × €149 = €298/year.
Annual Pro, 2 cottages: 2 × €149 = €298/year + VAT · spring + autumn visits + anti-mould + a photo per unit

Both cottages serviced before the season, photos added to the listings, no AC complaints since
Hello. I’m Ingrid, 67, retired to São Martinho do Porto. I have an LG split in the living room from 2018. Last June we turned it on and it smelled strongly of mould, so I switched it off. I’d like it serviced before this summer. How much exactly, with a fixed price in writing first? I’ll pay by card or transfer, and I’d like the invoice by email. In English, please.
Ingrid · 10:45
Hello Ingrid. A one-off service is €85 per unit + VAT, a fixed price you know before we start: a deep-clean of the filters and coil (that clears the built-up musty smell), a gas check, a test in cooling and heating, and a report on paper plus by email. A morning in spring suits best. We take card, MB Way or bank transfer, and everything is explained in English. If you’d like it done every year without remembering, the Annual Pro is €149/year.

Serviced in spring; musty smell gone, invoice emailed, comfortable all summer
Hello, we have a house near Foz do Arelho we use a few months a year and live in the Netherlands the rest of the time. It has three splits. Every time we come back the house smells damp and the AC smells stale until it’s cleaned. Can you service and clean all three before our next stay, while we are away? A neighbour holds the keys, and we’d need the invoice by email.
Hans & Greet · 16:18
Yes, we do this for many part-year owners. We arrange access with your neighbour, deep-clean all three indoor coils and filters (that damp, stale smell is mould on the coil), check the gas and drainage, and run them before you arrive. We email you photos, the report and the fatura, and you pay by transfer. The Annual Pro (€149/unit/year, 3 units = €447) builds in a pre-arrival spring visit each year, plus an anti-mould treatment, so you don’t have to remember.
A single visit, no contract. Ideal for newish equipment (a first service after installation that keeps the LG/Daikin/Mitsubishi warranty valid) or to try our team before committing to an annual plan.

What does skipping AC servicing cost?
Honest tables: what happens if you skip preventive servicing. Skipping it always costs more over time.

Dirty filters
+15–25% running cost
+€200–400/yr electricity

€180–350 emergency re-gas
Medium
Mould on the coil (closed-up house)
Smell, allergies
€100–200 reactive deep-clean
Medium
The Silver Coast is cooler and damper than the Algarve, so the musty smell in a closed-up house is the leading problem here. Left alone, reactive costs in year 1–2 can add up to €580–1,130 — well above the Annual Pro at €149/unit/year that prevents them, especially the anti-mould treatment for damp homes and allergies.

If you fitted AC during a renovation, the makers (Daikin, Mitsubishi, LG) require an annual service record to keep the warranty valid. Without it a claim can be refused. Our signed F-Gas Cat. I report covers that requirement.

For holiday cottages near Foz do Arelho, São Martinho, Nazaré or Peniche, a single 1-star review can take months of booking score to recover. A Portfolio plan at €119/unit, serviced before the season and after, means no AC failures at peak summer.

For an older or inherited system, or a house used part of the year: the Annual Pro (€149/unit/year) plus a HEPA H13 retrofit where needed (€35–65/unit) is the full package. We don’t need the original paperwork, we identify the model from the indoor and outdoor labels, and we arrange access with your key-holder.

Full coverage of the Silver Coast: Caldas da Rainha and Óbidos, the coast at Foz do Arelho, São Martinho do Porto, Nazaré and Peniche, and the towns and villages around Bombarral, Lourinhã and Alcobaça.

Call-out is included across the area; outlying spots may add a small charge, always agreed first.
Common questions about AC servicing on the Silver Coast
Yes. We deal with you in English from the first message to the report: booking, the visit, what we found and the invoice are all explained clearly.
The Silver Coast is cooler and damper than the Algarve, so a house shut up for a while grows mould and biofilm on the indoor coil, that’s the smell. A proper service removes it: we deep-clean the coil and filters, add an anti-mould treatment, and the smell goes. It comes back if the unit isn’t cleaned, which is why a yearly service helps.
Yes, we do this for many part-year owners. We arrange access with your key-holder or neighbour, service and clean the unit before your stay, and email you photos, the report and the fatura. You pay by transfer. The Annual Pro can build a pre-arrival spring visit into the plan each year.
Once a year for a home, ideally in spring before you arrive or before the heat. If you let the place or someone has allergies, twice a year (spring + autumn) is better. Rinsing the filters yourself between services helps too.
Yes. Daikin, Mitsubishi and LG require an annual service record to keep the warranty valid, a claim can be refused without it. Every visit comes with a signed report you can keep, valid for the warranty registration.
Yes, a split is a heat pump, so the same unit cools in summer and heats in winter. That matters here: Silver Coast winters are mild but damp, and a split is cheaper to run than electric heaters. Servicing keeps both seasons working.
Yes. The Portfolio rate (€119/unit/year) starts at 5 units; for two cottages we use the Annual Pro rate (€149/unit/year), with the same single arrangement that covers each cottage with two visits a year, scheduled around your bookings, one consolidated invoice with your NIF, and a clean photo per unit for your listing. We arrange key access locally so you don’t need to be there.
Within a few km of the sea (Foz do Arelho, São Martinho, Nazaré, Peniche) salt air is harder on the outdoor unit, so an annual service and a check of the casing matter more. We clean and protect it and flag any corrosion early, before it shortens the unit’s life.
Always. Every job comes with an official fatura showing your NIF, useful for your accounts or NHR/IRS. The warranty (6 months on replaced parts for Pro/Portfolio) is in writing and in English.
Yes. We service any brand, and we don’t need the original paperwork, common when you inherited the AC with the house. We identify the model from the indoor and outdoor labels and look up the maker’s specs. No documentation is required.
We service all the HVAC in the home, so you don’t need one company for the AC and another for the heat pump. That covers AC (any brand), hot-water and heating heat pumps (Daikin Altherma, LG Therma V, Mitsubishi Ecodan), pool heat pumps, and MVHR ventilation. One contact, one invoice. If you add a heat pump or MVHR later, it joins the same contract.
