Steps to maintain and repair your heat pump
The cost of maintaining an aerothermal system ranges from 100 € to 500 € if repairs are needed. If there is any malfunction or sign of deterioration, its location and the technical characteristics of the equipment can significantly influence the repair price.

1. Identify signs of malfunction
Watch for abnormal noises, insufficient heating or cooling, or water leaks in your heat pump system. These signs indicate professional maintenance is needed, typically costing between 100 € and 300 € depending on the issue's complexity. Early detection prevents expensive major repairs down the line.

2. Request professional technical inspection
Contact authorized heat pump installers to conduct a comprehensive technical inspection of your system. This diagnostic review is essential for determining equipment condition and maintenance costs. A qualified technician will evaluate critical components including the compressor, filters, and connections.

3. Get a maintenance quote
Request detailed quotes from multiple installers for your aerotermia maintenance. Basic services range from 100 € – 180 €, while standard maintenance costs 250 € – 350 €. Comparing quotes helps you evaluate included services and choose the best value for your budget.

4. Assess if major repair is needed
Based on the technical diagnosis, determine whether you need preventive maintenance only or major repairs. Basic maintenance starting at 100 € may be insufficient if components are damaged. Premium services ranging from 400 € – 500 € include replacement parts and more extensive repairs.
What can change your final price
Even similar projects can end with different budgets. These are the factors that most often push costs up or down.
Type of maintenance required
Annual preventive maintenance is more cost-effective (100-150€), while repairs to components such as the compressor or outdoor unit can reach 400-500€. Major breakdowns significantly increase the total cost.
Power and model of the heat pump system
Higher capacity systems (8-12 kW) require more review time and more expensive parts than low-power equipment. Newer models may also have more specialized and expensive replacement parts.
Age and condition of the system
Equipment over 10 years old typically requires more thorough maintenance and additional repairs. Deterioration from lack of previous maintenance can multiply repair costs.
Geographic location and accessibility of the unit
If the outdoor unit is in a hard-to-reach area, on the roof, or requires scaffolding, travel and labor costs increase. Work in rural areas may also include travel surcharges.

What maintenance does an aerothermal system installation require?
The cost of maintaining an aerothermal system ranges from 100 € to 500 € if repairs are needed. If there is any malfunction or sign of deterioration, its location and the technical characteristics of the equipment can significantly influence the repair price.
One of the characteristics of aerothermal systems is that their maintenance needs are very limited. However, these tasks are very important for the equipment to operate efficiently, to prevent malfunctions, and to extend the lifespan of the devices.
How often does aerothermal system maintenance need to be performed?
The cost of maintaining an aerothermal system ranges from 100 € to 500 € if repairs are needed. If there is any malfunction or sign of deterioration, its location and the technical characteristics of the equipment can significantly influence the repair price.
It is recommended to perform an in-depth inspection of the aerothermal system every year, although the Regulations for Thermal Installations in Buildings (RITE) specify that for equipment with power below 70 kW, inspections should be carried out every two years.
These inspections aim to check the safety conditions and performance of the equipment, resolve anomalies that could lead to bigger problems, and keep the different elements of the aerothermal system clean to optimize its operation.
- Review of the water circuit pressure.
- Review of the outdoor unit battery.
- Filter cleaning.
- Refrigerant check.
According to the Regulations for Thermal Installations in Buildings (RITE), heat generation equipment with power below 70 kW must undergo a mandatory inspection every two years. However, only in installations with power above 70 kW is it mandatory to enter into a contract with a maintenance company.
In any case, the recommendation is to perform aerothermal system maintenance work every year. These would be preventive works that should always be performed by a qualified professional.
These maintenance works include tasks ranging from filter cleaning to motor or circuit inspection. It is important that they are always performed by qualified professionals.
- Review of electrical connections.
- Technician labor: 65 €/h
- Assistant labor: 40 €/h
- Travel: up to 65 € or 1.4 €/km
