Installation and fitting of HVAC equipment in Barcelona

Installation of heating systems in Barcelona: professional design and installation by HVAC Barcelona


Many people mistakenly believe that it is always summer in the capital of Catalonia. However, any resident of Barcelona knows that from November to March, high humidity and the lack of central heating make homes quite cold. The right choice and high-quality installation of a heating system is the key to not only comfort but also the durability of your renovation. HVAC Barcelona (www.hvac.barcelona) offers professional solutions for heating flats and private homes in Barcelona and the surrounding area.

 


The specifics of heating in Barcelona and its suburbs
The heating season in Barcelona is short but intense. Due to the maritime climate, a temperature of +5°C feels like zero, and the walls of old buildings in the Ciutat Vella or Gràcia districts quickly accumulate dampness.
HVAC Barcelona specialists select heating systems based on the architectural features of your home:

 

Apartments in the historic centre: Often, it is not possible to install gas heating or powerful external units here. We offer the installation of energy-efficient electric radiators with heat accumulators or inverter air conditioning systems that can heat at extremely low temperatures.
Eixample district and modernist houses: High ceilings (up to 4 metres) require special power calculations. To prevent heat from escaping upwards, we design systems with enhanced convection or combined solutions.
Villas in the suburbs (Gavà Mar, Castelldefels, Sant Cugat): Here we most often install fully autonomous systems based on gas boilers or innovative aerothermal technology.


Types of heating systems we install
HVAC Barcelona has all the necessary licences and permits in Spain to work with gas, water and electrical equipment.

 

Gas heating (Gas Natural): The most popular option in Barcelona. We install modern condensing boilers (Daikin, Vaillant, Saunier Duval), which save up to 30% gas compared to older models. We take care of all pipe layout and radiator installation.
Aerothermal systems: This is the "gold standard" in modern Europe. A heat pump heats water for radiators or underfloor heating, consuming a minimum of electricity.
Electric heating: Installation of modern convectors with software control that can be operated via a smartphone.
Air heating: Use of ducted air conditioning systems to quickly heat the entire house through a network of air ducts.


Technical stages and quality guarantees

 

We approach installation as a comprehensive engineering process. Working with HVAC Barcelona includes:
Accurate thermal calculation: We calculate the number of radiator sections individually for each room, taking into account the glazing area and the quality of wall insulation.
Legalisation and documentation: Upon completion of the work, we issue an official certificate (Boletín de calefacción), which is required to conclude contracts with energy companies in Spain.
Use of quality materials: We use only certified pipes (copper, multilayer metal-plastic) and reliable shut-off valves, which eliminates leaks in the future.
Meeting deadlines: We understand that heating is needed "yesterday", so we work quickly and efficiently.
HVAC Barcelona is your reliable partner in creating warmth and comfort.

 

We work throughout Barcelona and the Metropolitan Area, providing the highest level of service.
