Install your new air conditioning system with Endesa and benefit from our highly efficient equipment

Cleaning the filters, checking the drainage and cooling systems, verifying the refrigerant gas levels, and cleaning the exterior of the unit are part of regular air conditioner maintenance. You can keep your air conditioning unit in tip-top condition with our air conditioning maintenance service. Royal Decree 1027/2007 governing Thermal Installations in Buildings requires you to service your climate control appliances every two years.

Look for the SEER (Seasonal Energy Efficiency Ratio for cooling mode) and SCOP (Seasonal Coefficient of Performance for heating) or EER (Energy Efficiency Ratio). Also, make sure you choose a model with the right capacity for the size of your room, and keep up with regular maintenance to maintain efficiency over time.

Maintaining heating systems or boilers is more complex, as it is necessary to check all installation components (valves, fittings, pipes, nozzles, ventilation…), verify the gas installation for leaks, adjust the equipment’s operation, and also perform a combustion analysis.
