What we do

Maintenance according to the equipment you have.

The maintenance for a gas boiler is not the same as for a heat pump, a multisplit, or a photovoltaic solar installation. Each system has its critical points — and we address them all.

Hire maintenance
Three maintenance options: one-time, annual, and premium with assistance
Choose mode

Three ways to hire maintenance.

Depending on how you use the equipment and how much peace of mind you want. From a one-time inspection to a premium contract with priority assistance.

Single visit i

Scheduled maintenance

A visit, a certificate. Perfect for those who just want to stay up to date with the regulations or certify the condition of the equipment before a property sale. No further commitment.

Most contracted ii

Annual contract

One inspection per year on the date that suits you best, signed certificate, automatic reminders and discount on any one-time repair of the equipment. The most common option for families.

Total peace of mind iii

Premium with assistance

Annual contract + priority assistance in faults Within 24-48 hours, diagnosis at no cost and discounted labour for urgent repairs. Designed for communities, rentals, and tourist accommodation.

What does each visit include?

Five critical points, none above.

Professional maintenance is not just "wiping down." It involves five technical inspections that make the difference between equipment that lasts 20 years and one that fails after 8.

01

Combustion / pressures

Approved analyser in gas boilers. Refrigerant pressures in air conditioning and aerothermal systems. Early detection of deviations before they translate into a fault.

02

Tightness

Certified gas leak detector in boilers. Refrigerant leak detector in refrigeration equipment. Prevents serious faults and complies with regulations.

03

Technical cleaning

Burner, heat exchanger, air filters, batteries, drains, and fan. A dirty unit loses 10-15% efficiency and puts strain on the compressor or burner.

04

Wear components

Expansion vessel, safety valve, circulating pump, NTC sensors, contactors, electrolytic capacitors. Cheap parts that prevent expensive faults.

05

Certificate + registration

Technical report signed with actual measured values, suitable for insurance and manufacturer warranty. Hand delivery and a registered copy in your history.

How we work

We do not tick boxes. We perform genuine maintenance.

Most "offer" maintenance services last 20 minutes and consist of cleaning filters and signing a paper. Ours lasts 45-70 actual minutes and leaves the equipment ready for its next season without surprises.

Combustion analysis with an approved analyser on a gas boiler
— Actual measurement

Approved analyser. Real values. Nothing subjective.

Each Uniclima technician carries a professional analyser (testo / Kane) calibrated within the official timeframe. We measure, record, and print. If the values are out of range, we show it to you on the display and propose the action. There is no "I think it's fine" in our maintenance.

  • Analysers with current official calibration
  • Values recorded in the equipment's technical data sheet
  • Comparison against previous review to detect drifts

— Real-time at home

45-70 minutes per unit. Not 15 minutes minimum.

A well-maintained gas boiler requires about 45-60 minutes. An air conditioning unit, 40-50. An aerothermal system, 60-70. If your previous maintenance lasted less than 30 minutes, it wasn't maintenance — it was a formality. We take the necessary time because we work on a fixed schedule, not on a flat-rate basis.

  • In-house technicians, not subcontracted on a piecework basis
  • Complete documented checklist, without omissions
  • Before and after photographs of critical equipment
Maintenance certificate signed with tools and spare parts
— Long relationship

The same technician who installed it returns for maintenance.

We assign a reference technician for each customer. They know your team, your installation, and the history of incidents. You won't have to explain from scratch each year what happened the previous winter. This is how we've been working since 2010 — and this is how we will continue.

  • Equipment history by customer and address
  • Automatic reminder for the next review
  • Discount on repairs for customers with a contract
The process

From the quote to the certificate, five clear steps.

Always the same. Always with the same reference technician. Always punctual with the agreed time slot.

i

Phone appointment

We offer available dates by time slot. You can choose morning, midday, or afternoon as it suits you best. Confirmation via SMS and WhatsApp.

ii

Notice before leaving

The technician calls you 30 minutes in advance. They arrive within the agreed time slot in 98% of cases. If there is a delay due to unforeseen circumstances, we notify you in real time.

iii

Technical maintenance

45-70 minutes depending on the equipment. Measurement, cleaning, verification of wear components, and functional testing before completion.

iv

Report and recommendations

Certificate signed with measured values. If we detect something that requires future repair, we will note it with priority — so you can assess it in advance, not urgently.

v

Reminder and follow-up

We automatically schedule the notification for the next service based on the type of equipment and usage. Your part ended when you signed. We take care of reminding you.

Contracts renewed year after year

What customers say about they do not change companies.

“

I have been with the same Uniclima technician for boiler maintenance for six years. He knows the equipment, knows what I've had, and alerts me to small issues before they become big ones. I haven't changed them because it works.

I subscribed to the premium service for the three rental apartments I own. The tenants can contact them directly if something goes wrong, and they resolve it before it escalates. Real peace of mind. Renewing for three years without questions.

Community of 32 residents with central heating. We switched to Uniclima 4 years ago after years with a company that would come, sign, and leave. The difference is night and day — fewer faults, genuine reports, and an adjusted invoice.

Frequently Asked Questions

Everything people ask about maintenance.

If your case is not here or you need specific technical guidance, call 91 117 77 77 and a technician assists you directly.

How often should maintenance be performed?

The RITE set every 2 years minimum legal for gas boilers ≤ 70 kW (most domestic) and annual for diesel. In practice, most manufacturers and insurers require annual maintenance to keep the equipment warranty valid and the home insurance coverage active.

For air conditioning, annual maintenance before summer is the norm. For aerothermal systems, annually at the change of season. The recommendation, except for exceptions, is always annual.

What is the difference between maintenance and an inspection?

The maintenance It is the set of preventive operations that extend the life of the equipment and prevent faults: cleaning, adjustment, safety check, and measurement. It results in a legally valid certificate.

One punctual review (without contract) it is a single technical visit to certify the current state of the equipment — for example, before selling the property or upon reaching the legal deadline without wanting to sign a contract.

Does maintenance free me from occasional repairs?

Not in the standard contract. Preventive maintenance significantly reduces the likelihood of a fault, but any unforeseen repair is charged separately — with an agreed discount for customers with an active contract (discounted labour and discount on spare parts).

In the mode Premium with assistance urgent visits within 24-48 hours and the diagnosis are included at no cost. Labour and spare parts are discounted according to the contract rate.

How much does the annual maintenance cost?

It depends on the type of equipment. As an approximate reference in 2026 in Madrid: domestic gas boiler around 85-130 € annually; split air conditioning 75-110 €; residential aerothermal 120-180 €; multisplit 2-4 units 110-160 €.

In communities and rentals with multiple units, we apply a volume-based rate. Request a tailored quote and we will provide it in writing without obligation.

What brand is my equipment?

No. We perform maintenance on all major brands. Our technicians have cross-training in Vaillant, Saunier Duval, Junkers/Bosch, Baxi Roca, Ferroli, Beretta, Ariston, Domusa, Daikin, Mitsubishi Electric, LG, Toshiba, Hitachi, Panasonic, and others.

If your equipment is from a less common brand, let us know when hiring to verify that we have compatible wear parts — but we can always perform the inspection itself.

Does my home insurance require up-to-date maintenance?

Most home insurance policies (MAPFRE, Mutua Madrileña, Línea Directa, Allianz, AXA, Zurich, among others) require up-to-date maintenance certificate to cover claims arising from the air conditioning equipment (leaks, fires, water damage from the expansion vessel).

The certificate we provide is suitable for insurance companies. You keep it with the policy and that's it — and if you need copies from previous years, we have them archived.

Do you perform maintenance on photovoltaic solar panels?

Yes. We maintain residential and small commercial photovoltaic installations. professional cleaning of panels (dirt accumulation reduces production by between 5% and 15% depending on the area), electrical verification of the inverter, review of DC and AC connections, and monitoring system analysis If available. At the end, we deliver a report comparing actual production vs expected.

Ideally, an annual inspection should be conducted at the change of season. If the installation is large or in an area with high pollution, twice a year. We will guide you according to your situation.

What areas of Madrid do you cover?

Home maintenance throughout Madrid capital (21 districts) and main municipalities of the metropolitan area: Alcobendas, Las Rozas, Pozuelo, Majadahonda, Tres Cantos, Boadilla, Alcalá de Henares, Coslada, San Fernando, Torrejón, Móstoles, Alcorcón, Getafe, Leganés, Fuenlabrada, Rivas Vaciamadrid, Villaviciosa de Odón, among others.
