1044 words • about 5 minutes reading

In today's world, an air conditioner is not just a luxury but a necessity, especially in Bulgaria, where seasonal temperature fluctuations test every air conditioning system. Whether you own an apartment in Sofia, a house in Varna, or an office in Plovdiv, a functioning air conditioner ensures comfort and health. But when do minor issues escalate into an urgent need for professional repair? How can we recognize the signs, and what are the current trends and prices in 2025? In this article, we will guide you through everything important about air conditioner repair, sharing practical tips, real examples, and little-known but extremely useful ideas.

Main Signs Your Air Conditioner Needs Repair

Often, users ignore early signs of malfunction, leading to more serious (and expensive) problems. Here are the first signals indicating the need for professional intervention:

Reduced efficiency: The unit is running but not cooling or heating sufficiently.
Unusual noises: If you hear rattling, whistling, or vibrations, this signals a mechanical problem.
Water or refrigerant leakage: Moisture on the wall or under the unit often means a clogged drain or a system breach.
Unpleasant odor: This can be caused by bacteria, mold, or a dirty heat exchanger.
Frequent shutdowns: Automatic stopping indicates an electrical or sensor problem.

Why Not Delay the Repair?

Small problems with air conditioners can quickly turn into costly breakdowns. For example, if you notice a refrigerant loss and do not seek a technician promptly, the compressor may burn out – its repair costs between 450 and 800 BGN. Ignored noise from a bearing can lead to fan damage, also increasing costs. At Fix!, we often see requests where users have waited for months, and then the repair becomes twice as expensive.

Common Repairs and Prices in 2025

Cleaning and disinfection: 50 – 90 BGN (including antibacterial treatment)
Recharging with refrigerant: 70 – 180 BGN (depending on the type and amount of refrigerant, R32 is cheaper than R410A)
Board replacement: 120 – 350 BGN
Compressor repair: 450 – 800 BGN
Sensor replacement: 40 – 80 BGN
Cleaning or unclogging the drain: 40 – 70 BGN

Prices vary by city (higher in Sofia, more affordable in Burgas), as well as by the brand of the unit – Japanese air conditioners usually require more specialized components.

Location and Legal Requirements

In Bulgaria, according to Ordinance No. 6/2003 and environmental laws, only licensed technicians are allowed to work with refrigerants. This applies to repairs in Plovdiv, Varna, Ruse, and all major cities. Always check if the technician has the necessary certificates – especially if the repair involves opening the refrigeration circuit or recharging with refrigerant.

Why Professional Help is the Best Choice?

Many owners try to repair their air conditioners themselves – YouTube is full of such videos. But the risks are huge: electric shock, refrigerant leakage, voiding the warranty. In 2025, with the advent of increasingly complex inverter models, mistakes can cost you the entire system. Professionals have the necessary tools, knowledge, and insurance – ensuring the repair is quick, quality, and safe.

Real Case: The Ivanov Family's Air Conditioner

In early January 2024, the Ivanov family from Sofia noticed that their air conditioner started working noisier, and the air wasn't as warm. With the help of Fix!, they posted a request, received three offers, and chose a technician with an excellent rating. It turned out the cause was a dirty heat exchanger and a worn bearing. After cleaning and replacing the bearing for 120 BGN, the unit worked like new. The Ivanovs share: "Without Fix!, we probably would have waited for months and spent twice as much money."

Unexpected Causes of Air Conditioner Damage

Micro-vibrations from the wall: If the air conditioner is mounted on a thin wall, construction vibrations can shorten the unit's lifespan.
Poor grounding: In old buildings, the lack of good grounding leads to board damage.
Changes in the power grid: Frequent "drops" in voltage in small settlements test the air conditioner's electronics.
Improper maintenance: Using chemicals not intended for cleaning air conditioners,
can damage the heat exchanger or disrupt the antibacterial layer.

How to Choose a Good Technician for Repair?

Always look for a specialist with real reviews and a guarantee for the service performed.

Frequently Asked Questions

What happens if I recharge the air conditioner with the wrong refrigerant?

Using the wrong refrigerant can cause serious damage to the compressor and electronics, and in some cases, a complete loss of warranty. In Bulgaria in 2025, recharging must be done only by a licensed technician with the appropriate tools and materials.

How often should air conditioner maintenance be performed?

Experts recommend maintenance at least once a year – preferably at the beginning of spring or autumn. This extends the system's life and reduces the risk of expensive repairs.

Can the air conditioner be repaired in winter?

Yes, most repairs can be done in winter, but recharging with refrigerant and some tests require temperatures above 10°C for optimal results. Always consult a specialist before planning a repair during the cold months.

How to recognize an unreliable technician?

Be cautious if the technician does not provide a quote with a guarantee, does not want to show certificates, or insists on advance payment without a contract. Fix! provides protection against unreliable contractors through a rating system and secure payment.
