Repair and maintenance of refrigeration equipment in Barcelona
HVAC-Barcelona is your trusted partner for technical servicing of commercial refrigeration equipment. We understand that in the restaurant and retail sectors, every minute of downtime for a refrigerator translates into direct financial losses and the risk of food spoilage. Our team provides a rapid response and high-quality repairs for freezers and commercial refrigeration systems of any complexity.
A professional service for your business in Barcelona
Commercial equipment requires a different approach to domestic appliances. Heavy workloads, complex electronics and the specific nature of refrigerants demand expert knowledge. We specialise in servicing:
Freezers and cold stores: Maintaining a stable sub-zero temperature for long-term storage.
Refrigerated display cabinets: Repair of medium-temperature systems for supermarkets, cafés and patisseries.
Bar equipment: Servicing of beer dispensers, beverage coolers and ice makers.
Blast freezers: Configuration of rapid cooling cycles.
What do we repair?
If you notice any irregularities in how your appliance is working, don’t wait until the compressor stops completely. The technicians at HVAC-Barcelona can effectively resolve the following issues:
Temperature control issues. If the compartment isn’t cooling or isn’t freezing properly, the cause may be blocked filters, a faulty thermostat or worn seals.
Freon (refrigerant) leak. The most common cause of loss of cooling. We locate the leak, restore the system’s seal and recharge it with certified gas.
Compressor failure. The system’s main ‘engine’. We diagnose the start-up protection relay and, if necessary, replace the motor-compressor.
Faults in electronics and controllers. Modern equipment is controlled by complex circuit boards. Our engineers program and repair control units (Dixell, Eliwell, etc.).
Unwanted noise and vibration. Often caused by worn fan bearings or system imbalance.
Ice build-up and ‘ice coating’. Faults in the defrost cycle (heating elements, evaporator sensors) lead to icing, which blocks air circulation.

Frequently asked questions about refrigeration equipment repairs
In this section, we’ve compiled answers to the most frequently asked questions from business owners in Barcelona to help you find your way around more quickly should any issues arise.
1. How quickly will a technician arrive at a site in Barcelona?
We understand that for a restaurant or shop, every hour of downtime means a loss of revenue. In most cases, our technician will arrive within 2–4 hours of your request. In urgent cases, we offer a ‘24/7 Emergency Repair’ service.
2. Do you operate in the suburbs of Barcelona?
Yes, we serve not only the city centre but the entire province: Badalona, L’Hospitalet, Sant Cugat, Mataró, Castelldefels and other nearby towns.
3. Why has my fridge stopped maintaining the correct temperature?
There could be several reasons: from something as simple as dust on the condenser to a freon leak or a faulty compressor. Only a professional diagnosis will reveal the exact cause.
4. How often should maintenance be carried out?
For commercial equipment, we recommend maintenance at least once every three months. During the hot summer in Barcelona, the load on the systems increases, so a check-up before the start of the season (in April–May) is essential.
5. How much does a technician’s call-out and diagnosis cost?
Provided that repairs are subsequently carried out by HVAC-Barcelona, the diagnosis is often free of charge or included in the total cost. Without repairs, the cost of the call-out depends on the distance to the site.
6. What parts do you use – genuine parts or equivalents?
We always prioritise genuine parts from manufacturers (Danfoss, Embraco, Copeland). However, if your budget is limited or a part is no longer in production, we will source a high-quality, certified equivalent.
7. Do you provide an official warranty?
Yes, all work carried out and parts fitted are covered by a warranty of between 3 and 12 months. We operate officially and issue an invoice (factura).
8. Why does the evaporator freeze over and develop an ‘ice coat’?
This is usually due to a fault in the defrost system: a faulty heating element, temperature sensor or a broken fan. This blocks the circulation of cold air.
9. What should I do if the fridge starts making a lot of noise?
Loud noise or vibration may indicate worn fan bearings, unbalanced blades or problems with the compressor mountings. It is recommended to switch off the appliance to prevent the motor from seizing up.
10. Do you offer refrigerant refilling services?
Yes, this is one of our core services. We use modern refrigerants approved for use in the EU: R134a, R404A, R410A, R290 and others.
11. Can the controller (control board) be repaired, or do I need to buy a new one?
If the damage is minor (for example, a blown relay), we carry out component-level repairs. In the event of serious damage to the processor, we recommend replacing it with a new one (Dixell, Eliwell, Carel).
12. Do you repair ice makers?
Yes, we repair both self-contained and mains-connected ice makers. The main issues in Barcelona are related to limescale, so we also offer filter installation.
13. What should I do if water is leaking from a refrigerated display cabinet?
Most likely, the drainage system is blocked or the evaporator has iced up. A technician will clear the drains and check the defrost cycle.
14. Do you work with equipment for florists?
Yes, we set up systems to maintain the specific humidity and temperature required for storing fresh flowers.
15. How can I reduce the energy costs of a fridge?
Regular cleaning of the condenser and checking the condition of the rubber seals can reduce energy consumption by up to 30%.
16. Do you install new cold rooms?
Yes, HVAC-Barcelona provides a full turnkey service for the design and installation of cold rooms – from the assembly of sandwich panels to the commissioning of the refrigeration unit.
17. What is a ‘leak in the foam-filled section’ and can it be repaired?
This is a complex fault inside the cabinet. We have the equipment to open up and restore the seal of such units, which is much cheaper than buying a new display cabinet.
18. Is it possible to convert a refrigerator from one type of refrigerant to another?
This is known as a retrofit. The procedure is possible but requires replacing the oil in the compressor and, sometimes, the expansion valve itself. We carry out such work in accordance with environmental standards.
19. What are the signs that a compressor is about to fail?
Excessive heat from the casing, frequent on/off cycling, a metallic knocking sound when starting, or oil stains beneath the unit.
20. How do I book a repair?
You can call us or message us on WhatsApp. We’re open every day!
