ANNA cares for your home.
Comfort · Climate · Energy. Electrical, climate control and energy work to keep your home running as it should.
The Challenge
Your home has a lot of things to look after.
And when something breaks, you usually start by looking for someone to call. ANNA changes that. One single relationship to take care of your home's technical needs.
See how it worksYou don't need to know your home's technical ins and outs. You need someone who does.
ANNA documents and learns every technical detail of your home to anticipate its needs.

- Home charging point (wallbox) installation
- Annual connector inspection and firmware updates
- Dynamic load balancing
- Electrical certificate (CIE) processing for added power
Connector, firmware and load balancer checked once a year so your car always charges at the maximum speed allowed.
Automation
Home automation and zoning genuinely configured for how you actually live in your home, not just at initial install — we adjust scenes and priorities to real usage.
- Zoning setup and reconfiguration (Airzone-type systems)
- Combined lighting and climate control scenes
- Device integration into a single control app
- Diagnostics for existing home-automation systems
We reconfigure scenes and priorities room by room to match how the home is actually used, not just at install time.
Technology & networking
Structured cabling, wifi coverage and well-planned network points so every corner of the house gets the signal it needs — no improvised repeaters, no cables left on show.
- Network cabling installation and extension (RJ45, fibre, coaxial)
- Whole-home mesh wifi coverage, with no dead zones
- Network and TV points built into the walls, room by room
- Diagnostics and optimisation of your existing router and equipment
We measure the real coverage of every room before deciding where each network point or repeater goes — never by guesswork.
A different way
to care for your home.
A process designed for peace of mind. From the first contact through to ongoing maintenance.
You tell us what's happening, in your own words
You call and describe the problem or what you need in your own words: "the power's gone," "something smells burnt," "I want some new sockets fitted," "the air conditioning isn't cooling." You don't need to know the technical terms — that's our job.
Questions anyone can answer
We ask a few simple questions to understand your case properly — nothing that requires knowing anything about electrics or climate control, just telling us what you're seeing. You'll notice you're talking to someone who knows the trade, not someone reading from a script.
A clear estimate, on the same call
We tell you how long the work is likely to take and what the labour will cost, before VAT —this can vary depending on the job and the location— and without including any materials that need replacing, which are confirmed at the visit itself.
You choose how you want to receive it
If you're happy to go ahead, we ask where you'd like the quote sent: the phone you're calling from, another number, or your email. As soon as you confirm, we send it — while we carry on talking about the next step.
We find the best slot, in real time
While we're still on the phone, we check the diary of the technicians in your area who specialise in your problem, and work out whether the job needs splitting across more than one visit because of how long it will take.
Appointment confirmed, with a name and a face
We tell you who's coming and send you, through the same channel as the quote, the appointment for your calendar and the technician's card: their vehicle (make, model and licence plate) and their certifications.
We already know you
With that, everything's set. If you call again, we already know who you are: you can book another service or update your details, your quote or your appointment, without going through the whole story again.
A reminder, 24 hours ahead
The day before the visit, we remind you about the appointment, so it's on your radar without you having to check the calendar.
We keep an eye on delays
Two hours beforehand, we check on the technician's status and, if we expect any delay, we let you know with time to spare.
You know where your technician is
An hour and a half before the expected arrival, we send you the technician's live location, so you don't have to keep watching the clock.
We come in with respect for your home
The technician works with shoe covers and, if any drilling is needed, with dust-extraction equipment fitted to the tools.
They explain before touching anything
The first thing the technician does is tell you what they're going to do and how, so there are no surprises while they work.
A report and payment, once it's done
When the work is finished, you receive a detailed report of what was done, along with the payment link for the service.
We check back, a week later
We get in touch to confirm everything's still working well and we can mark the job as closed. If we need to come back to fully resolve it, we book another visit.
We invite you to tell us about it
Once you confirm the job's closed, we invite you to leave us a review — your opinion matters to us.
Care plans
Choose your level of peace of mind.
It's not insurance. It's not just another technical service. It's a relationship: ANNA knows your home, and you know who to call.

Annual Maintenance & Boiler Combustion Analysis
Protects your home's comfort, cuts gas consumption and keeps you compliant with current RITE (Spanish thermal installations regulation) requirements.
With continued use, the burner accumulates impurities and soot builds up in the flue passages. This forces your boiler to work harder and can increase fuel consumption by up to 15 %. Our annual preventive maintenance service is designed under RITE regulations to clean your equipment and digitally calibrate its operation, ensuring maximum energy efficiency and total safety for your family.
What does our inspection service include?
- Technical cleaning of the heat exchanger block: We remove soot and accumulated deposits from the deflectors and heat exchangers to restore the unit's original heat-transfer capacity.
- Digital combustion gas analysis: We insert an electronic probe into the flue outlet to precisely measure Oxygen (O₂), Carbon Monoxide (CO) and Carbon Dioxide (CO₂) levels, confirming clean combustion and ruling out dangerous backflow of harmful gases.
- Analytical performance ticket: We hand you the printed readout from our certified analyser, detailing your boiler's exact efficiency percentage and correct calibration.
- Visual inspection and safety check: We check that the flue ducts are completely clear, that seals remain airtight, and that water circuit pressure is at the optimal level to prevent breakdowns in the coldest months.
- Everything in the Essential plan
-
Seasonal maintenance (2 visits a year)
We don't wait for equipment to fail; we prepare your home proactively, ahead of Madrid's extreme seasonal weather.
- Winter phase (heating start-up): Technical system purge, hydraulic balancing of the underfloor heating manifolds floor by floor, and a check of the circulation pumps. We ensure even warmth throughout the home from the first cold day, with no phantom consumption.
- Summer phase (air conditioning tune-up): Thorough sanitising of filters and ducts (eliminating bacteria and odours), a check of refrigerant gas levels, cleaning of the outdoor unit (removing accumulated pollen and dust), and a condensate drainage check to prevent leaks.
-
Priority response for breakdowns
On-site technical assistance at your home in under 24 hours.
The definitive plan for highly electrified homes.
- Everything in the Confort plan (including both full seasonal visits)
-
VIP on-call support, 24/7/365
A priority direct line by WhatsApp and phone. If your heating cuts out in the middle of a winter weekend, or your main system fails on a public holiday, you have guaranteed urgent on-site assistance with no emergency call-out charges.
-
EV Charging Point Maintenance
An annual inspection of your smart charger. We check the connector's condition, update its firmware, and verify that the dynamic load balancer is working correctly, so your car always charges at the maximum speed available.
-
Preventive Thermal Imaging of the Consumer Unit
We scan your home's main consumer unit with an infrared thermal camera during the annual visit. This lets us detect "hot spots" invisible to the naked eye (loose terminals or overloaded circuit breakers), preventing unexpected power cuts or fire risk from overload.
-
Electrical Certificate (CIE) management at no technical cost
If you decide to move to high electrification (buying an electric car, adding an air-source heat pump, or heating a pool), we carry out the load study and issue the official Electrical Installation Certificate for the Comunidad de Madrid free of charge (you only pay the distributor's official fees).
Monthly price per household.

What fails most often (and how to prevent it)
Technical diagnosis before it becomes a breakdown.
These are the most common issues we see in homes across our three service areas, with the real cause, its effect, and how we prevent it.
Poorly calibrated air-source heat pump or underfloor heating
- Cause
- The heat pump and its operating curves were left on factory settings at installation, never adjusted to the actual home.
- Effect
- Areas of the home that are slow to heat or cool, higher consumption than necessary, and a sense that the system "can't keep up" with the house.
- Prevention
- An annual review of flow rates and heating/cooling curves, with no need to touch the flooring or existing installation.
- ANNA's diagnosis
- We measure room-by-room temperature and system response time to recalibrate it to the real home, not the catalogue spec.
Consumer unit with insufficient capacity
- Cause
- Installations designed 15-30 years ago for the consumption levels of the time, with no headroom for climate control, induction hobs and an electric vehicle all at once.
- Effect
- The trip switch cuts out at the worst possible moment — usually when the home's comfort is needed most.
- Prevention
- A review of contracted power against actual consumption before adding new equipment, not after.
- ANNA's diagnosis
- We inspect the consumer unit, arrange the electrical certificate (CIE) where needed, and size the installation for what the home actually needs today.
Ducted air conditioning with no maintenance
- Cause
- Filters and indoor units that never get checked because they're hidden above the false ceiling, out of everyday sight.
- Effect
- Loss of performance, gradually increasing noise, and worse indoor air quality, without anyone noticing why.
- Prevention
- Periodic cleaning and inspection of filters, grilles and units, before the equipment has to strain to compensate.
- ANNA's diagnosis
- Included in the ANNA Passport: we log the condition of every unit to anticipate maintenance before it becomes noticeable.
Poorly configured home automation and zoning
- Cause
- Zoning systems (such as Airzone) installed but with scenes and priorities only ever set up at initial commissioning.
- Effect
- Rooms getting climate-controlled when they don't need it and others falling short, with higher-than-expected electricity consumption.
- Prevention
- Reconfiguring scenes and priorities room by room based on how the home is actually used, not just at the time of installation.
- ANNA's diagnosis
- We adjust the zoning logic and lighting scenes from a single app, tailored to how the home is really lived in.
