An air conditioning unit that is not serviced every year loses between 15 and 30% of its efficiency. Filters accumulate dirt, the refrigerant circuit can develop small leaks that go unnoticed, and electrical components operate under more stress than necessary. The result is a unit that consumes more energy, cools or heats less effectively, and breaks down earlier than it should.
At JAG Alcaide we offer an annual maintenance contract for air conditioning units in Barcelona that covers a full technical inspection and all labour and call-out costs for any breakdown that arises throughout the year. This is not a simple filter clean — it is a complete system service.
Do you want your air conditioning installation to always offer you maximum performance? Are you tired of the Air Conditioning getting less cold every year? Do you want to be covered against any breakdown that may arise in your air conditioning installation? We offer a maintenance service for air conditioning devices that will offer the solution to your concerns.
What does the annual service include?
| Service point | What we check | Why it matters |
|---|---|---|
| Indoor unit cleaning | Full disassembly, deep clean with disinfectant and odour eliminator formulated for air conditioning units | Dirty filters reduce airflow and become a breeding ground for bacteria and mould |
| Refrigerant gas check | Refrigerant circuit pressure verification. Electronic leak detection equipment used on all units | A minor gas leak reduces efficiency by 25–40% without the user noticing any obvious symptoms |
| Thermal differential | Measurement of the temperature difference between intake air and treated air output | Confirms the unit is producing cold or heat at the correct performance level |
| Electrical inspection | Connections, amperages and capacitor condition checked | Corroded or loose connections are the most frequent cause of electrical failures |
| Outdoor unit inspection | Condenser coil cleaning, fan inspection and check for abnormal vibrations | A dirty outdoor condenser can increase electricity consumption by up to 20% |
| Breakdown cover | Labour and call-out included for any breakdown throughout the year. Parts charged at cost price | A single out-of-contract callout can cost €80–200 in diagnosis and travel alone |

Is the contract worth it, or is it better to call when something breaks?
| With JAG Alcaide contract | Without contract (pay per call) | |
|---|---|---|

The contract makes particular sense if the unit is more than 3 years old, if it runs intensively (more than 6 months a year), or if no service has been carried out since installation. For units still under manufacturer warranty, annual maintenance is also a condition for keeping that warranty valid.
Frequently asked questions about air conditioning maintenance in Barcelona
When is the best time to schedule the annual service?
Spring is ideal — before the heat arrives and the unit starts running at full load. If you wait until July when it is already hot and the unit fails, waiting times can stretch to several days as it is peak demand season. With a contract, we schedule the visit at a time that suits you.
Does the contract cover all air conditioning brands?
Yes. We service any brand: Mitsubishi Electric, Bosch, Daikin, Fujitsu, LG, Samsung, Panasonic and others. The unit does not need to have been installed by us to be eligible for a maintenance contract.
What happens if the unit needs a spare part?
The contract covers labour and call-out. Spare parts are charged at cost price with no added margin. Before carrying out any repair involving parts, we inform you of the cost and wait for your approval.
How many units can I include in the contract?
The contract can be tailored to any number of units — from a single split to multi-split systems or ducted installations with several outlets. Pricing varies according to the number of indoor units. Call us and we will prepare a personalised quote.
Does the service include refrigerant gas recharging?
The service includes a refrigerant circuit check and electronic leak detection. If a leak is found and a gas recharge is needed, this is handled as a separate intervention and quoted accordingly, as refrigerant gas costs vary by type and volume required.
Do you work with residents’ communities and businesses?
Yes. We manage maintenance contracts for private individuals, residents’ communities with centralised installations, offices, commercial premises and hotels. For installations with multiple units, we carry out a free preliminary inspection to assess the scope of the contract before quoting.
