HVAC Barcelona provides aerothermal heat pump solutions in Badalona for apartments, detached houses and commercial properties.
We select and supply heat pumps, install water-based heating systems and provide solutions for cooling and domestic hot water production.
Our services include underfloor heating installation, radiators, fan coil units, replacement of existing equipment, control system configuration, commissioning, diagnostics, repairs and technical maintenance.
Each solution is designed according to the specific characteristics of the property, including its floor area, insulation and building envelope, room layout and the requirements of its occupants.
If you already have an aerothermal heat pump system but some rooms heat unevenly, hot water runs out too quickly or the equipment frequently stops operating, you can request an inspection of the existing installation.
For new installations, we begin by assessing the property and its technical conditions. For repairs, our first objective is to identify the cause of the malfunction.
Installing a more powerful heat pump, increasing the water temperature or replacing an expensive component without proper diagnostics should not be the first step.
It is important to determine where the problem originates: in the equipment itself, the hydraulic circuit, the heating emitters or the control system.
Aerothermal technology uses outdoor air as a heat source and transfers this energy to the building's water-based heating system.
Electricity is required to operate the compressor, fans, circulation pumps and control system.
In heating mode, water is distributed to underfloor heating circuits, radiators or fan coil units.
Domestic hot water is produced through a storage tank included in the system design.
The possibility of summer cooling depends on the heat pump model and the compatibility of the indoor equipment.
Having an aerothermal system does not automatically mean that every connected radiator can be used to cool a room.
When selecting equipment, we calculate the requirements of the entire system.
The heat pump must provide the necessary heating or cooling capacity under the design conditions, while the distribution network must deliver that capacity to the different rooms.
Comparing equipment based only on its nominal capacity in kilowatts is not sufficient.
Other important factors for the property owner include the required water temperature, available electrical power, comfort requirements, space for a hot water storage tank and operating costs.
We explain the differences between possible system configurations and agree on the scope of work before installation begins, ensuring that the customer understands the purpose of every component included in the quotation.
We accept service requests throughout Badalona, including Centre, Dalt de la Vila, Canyadó, Gorg and other neighbourhoods.
The property's address is primarily needed to assess the building and organise a technical visit.
The required heat pump capacity and the most suitable model cannot be determined from the neighbourhood name alone.
Two neighbouring apartments may have different windows, building orientations, insulation levels and equipment installation possibilities.
For this reason, our equipment selection is based on an actual building assessment rather than general assumptions about the city.
For apartments, we first determine where the outdoor unit can be installed, how the indoor components can be positioned and where the pipes and connections can be routed.
On balconies or in confined spaces, we assess unrestricted airflow and the access needed for maintenance.
In internal courtyards, we pay particular attention to neighbouring windows, vibration and the possibility of cold discharge air recirculating towards the heat exchanger during winter.
For properties near the sea, we also consider environmental exposure and the manufacturer's requirements for equipment protection.
Installation clearances and protective measures are not determined by guesswork. We verify all installation requirements against the technical documentation for the selected model.
In existing buildings, separate routes may be needed for pipes and electrical connections.
Before starting work, we discuss wall penetrations, restoration of finishes and the location of connections that must remain accessible for maintenance.
If the installation affects common areas of the building, we check whether approvals are required before work begins.
Available space next to a building façade does not necessarily mean that the location is technically suitable or that it can be used without permission.
This approach helps prevent modifications and additional work after the system has already been installed.
For new water-based underfloor heating installations, we calculate the circuit layout and plan the distribution manifolds and individual room temperature controls.
Comfort depends not only on the heat source but also on the floor construction, floor covering and correct water flow adjustment.
Before installation, we agree on the required floor build-up height and check material compatibility.
If underfloor heating is already installed, we inspect the manifold, circulation pumps, mixing units and actual circuit performance.
An existing installation can only be retained after confirming that it is compatible with the new operating temperatures and provides sufficient water circulation.
When replacing a boiler with an aerothermal heat pump, we evaluate the radiators in each room individually.
We consider their dimensions, type, calculated heat output and the heat losses of each room.
In some cases, existing radiators are suitable. In others, additional radiator sections, replacement of certain radiators or improvements to the building's thermal insulation may be necessary.
We do not promise identical energy savings for every installation.
The higher the required water temperature, the more carefully the performance and efficiency of the selected heat pump must be evaluated under those operating conditions.
Another important objective is achieving even heating throughout the property.
Hot water leaving the heat pump does not necessarily mean that sufficient heat reaches the rooms furthest from the equipment.
We check hydraulic balancing, regulating valves, air in the system and filter condition.
The difference between a cold bedroom and an overheated living room may be corrected by adjusting water flow distribution rather than increasing the temperature of the entire system.
This is particularly important in properties with several heating zones and different temperature preferences.
For effective cooling, we consider fan coil units with suitable condensate drainage and proper insulation of cold-water pipes.
Equipment is selected according to the cooling load, furniture layout and acceptable noise levels.
The drainage system is designed as an essential functional part of the installation.
Condensate must be removed reliably, connections must remain accessible and any required condensate pump must be serviceable.
Conventional radiators should not automatically be included in a cooling system.
Using underfloor circuits for cooling requires separate calculations, humidity control and limits on floor surface temperature to prevent condensation.
We select domestic hot water storage tanks according to actual consumption: the number of occupants, the number of showers, possible simultaneous water use and the time needed to restore the hot water supply.
Tank capacity is not the only selection criterion.
Other important factors include the compatibility of the heat exchanger with the heat pump, the available installation space and the system's control modes.
We discuss the priority given to domestic hot water production in relation to space heating, as well as the hygiene functions provided by the manufacturer.
Specific temperatures and settings are determined for the selected system. There is no universal configuration suitable for every hot water storage tank.
Work begins with an agreed installation diagram and equipment list.
We prepare mounting supports, install pipework, complete electrical connections and fit the necessary components of the hydraulic circuit.
The selection of protective devices, filtration equipment and expansion components is determined by the system design.
A buffer tank or additional circulation pump is installed when technically necessary, rather than simply because these components are used in other installations.
For refrigerant connections and outdoor water pipes, we follow the requirements applicable to the specific equipment and installation configuration.
After installation, we check system tightness, air removal, water circulation and correct sensor connections.
During commissioning, we configure heating, cooling, domestic hot water production and individual zone operation within the capabilities of the control system.
We check transitions between operating modes and the interaction between pumps and valves.
The user receives an explanation of the main controls and agreed operating parameters.
If the final assessment of heating performance requires low outdoor temperatures, we discuss an additional inspection during the winter heating season.
Initial commissioning and confirming comfort under winter heating loads are two different tasks.

A technical diagnosis is recommended when controller errors, pressure drops, water leaks, insufficient heating, unusual noises or increased electricity consumption occur.
To prepare for the service visit, it is useful to provide the equipment model, a photograph of the error message and a description of the circumstances.
This should include when the problem appeared, which operating mode is active and whether domestic hot water production is also affected.
This information helps us prepare for the visit but does not replace technical measurements.
The same symptom may have several different causes. Therefore, repair costs are determined after identifying the fault and agreeing on the necessary work.
We inspect the hydraulic circuit, circulation pumps, sensors, valves, control settings and available operating parameters.
When necessary, we also examine the refrigerant circuit and electrical components using the appropriate diagnostic procedures.
Replacement parts are selected according to compatibility and supply conditions.
We do not recommend repeatedly resetting safety protections simply to keep the equipment running without resolving the underlying problem.
The objective of the repair is to restore normal operation and explain to the customer which actions or operating conditions contributed to the malfunction.
Technical maintenance includes an agreed range of procedures appropriate for the installed model and the complete connected system.
We inspect accessible components for contamination, check connections, filtration, pressure, drainage and control devices.
When necessary, we carry out cleaning and adjustments.
Maintenance intervals are determined according to the manufacturer's documentation and actual operating conditions.
Regular inspections help identify developing problems, but they do not replace repairs to damaged components or guarantee that equipment will never experience a fault.
Can existing radiators be retained?
This is determined after checking their heat output at the new operating temperatures.
If some radiators cannot provide sufficient heating, we will propose changes for individual rooms rather than automatically replacing all the equipment without calculations.
Is an aerothermal heat pump suitable for an apartment?
Feasibility depends on the location of the units, pipework routes, electrical supply and building conditions.
We begin by reviewing photographs and inspecting the property, then propose a technically feasible solution.
Why do installation costs differ between properties of the same size?
Differences may result from heat losses, domestic hot water requirements, existing heating emitters and installation complexity.
The quotation should reflect these differences and clearly define the scope of work.
How can I request equipment selection or repairs?
Send HVAC Barcelona the property address in Badalona, floor area, photographs and a description of the required work.
For an existing installation, also provide the equipment brand, model and details of the malfunction.
We will arrange a technical inspection and prepare a proposal for installation, configuration, commissioning, repair or maintenance.
When an apartment owner is deciding between retaining existing radiators and installing fan coil units, it is useful to define the summer cooling requirements first.
Radiators may be suitable for heating after their performance has been checked, but they do not automatically provide effective cooling.
Fan coil units require installation space and condensate drainage, but they can be used for both heating and cooling.
When comparing quotations, these options should be evaluated according to the desired result rather than only the cost of the heat pump.
Adding a new function may require modifications inside the apartment even when the same outdoor equipment is used.
Another common situation is a balcony with limited space.
In this case, we first check installation requirements, airflow and access to the equipment before discussing a specific model.
The most compact unit should not be selected solely according to its casing dimensions.
The clearances specified by the manufacturer must also be maintained around the equipment.
During the inspection, it is useful to show the entire balcony, the proposed pipework route and nearby windows.
This helps confirm installation feasibility before purchasing equipment and avoids having to relocate it after installation.
