When customers ask us which air conditioner to choose for their apartment, the answer almost always includes one Japanese name — Daikin. That’s no accident. In the industry, they say Daikin is the “Mercedes” of air conditioners: precise engineering, silent operation and a longevity that justifies every cent. In this article, we break down everything you need to know — from technology to prices — so you can make an informed decision before buying.
What is Daikin and why is it a global leader?
Daikin Industries was founded in Osaka, Japan, in 1924 and today is the No. 1 manufacturer of air conditioning equipment in the world by sales volume. The company operates in more than 150 countries and produces air conditioners, heat pumps and ventilation systems under its own brand.🏆 Daikin by the Numbers

BTU and Area: How to Choose the Right Capacity
The most common mistake when buying an air conditioner is choosing the wrong capacity. An undersized unit runs nonstop without cooling enough. An oversized one cycles on and off in short bursts, which wears out the compressor. Here’s how to get your bearings:1
Measure the room’s floor area (m²)
Multiply the length by the width of the room. For attic or irregular rooms, add a 20% reserve.2
Compare with the table below
Rule of thumb: 35–40 W/m² for a standard room with normal insulation in Bulgaria.9 000 BTU
up to 25 m²
12 000 BTU
25–35 m²
18 000 BTU
35–55 m²
24 000 BTU
55–75 m²
3
Account for additional factors
A south-facing orientation, panoramic glazing or an attic floor call for an increase of 15–20%. If there’s a boiler or a lot of equipment — an additional 10%.| Capacity (BTU) | Capacity (kW) | Area (m²) | Typical room | Energy class |
|---|---|---|---|---|
| 9 000 BTU | 2,5 kW | up to 25 m² | Bedroom, children’s room | A++ |
| 12 000 BTU | 3,5 kW | 25–35 m² | Apartment living room | A++ |
| 18 000 BTU | 5,0 kW | 35–55 m² | Open-plan living room + kitchen | A+ |
| 24 000 BTU | 7,0 kW | 55–75 m² | Studio, spacious living room | A+ |
* Values are approximate for standard insulation and 2.7 m ceilings. For non-standard conditions, we recommend a free consultation with one of our engineers.
💡Practical tip from our installers: If you’re torn between two models, choose the more powerful one. Running at 70–80% of capacity, the compressor is more efficient, quieter and wears out much more slowly.

Key Technologies: What Makes Daikin Different
❄️
Bluevolution + R32
Daikin is a pioneer in the transition to the refrigerant R32 — with 68% lower global warming potential than R410A. Bluevolution is the combination of R32 and an optimized inverter system that achieves up to 35% energy savings compared with the previous generation.
🦠
Flash Streamer
A patented purification technology available in Perfera and Stylish. The plasma discharge neutralizes up to 99.9% of bacteria, viruses and allergens (including pollen and dust mites), without ozone. Especially valuable for families with children and allergy sufferers.
📱
Daikin Online Controller
The Wi-Fi adapter (built into Comfora and above) lets you control the unit from a smartphone, anywhere in the world. You can switch on the heating 30 minutes before you get home, set a weekly schedule or check power consumption in real time.
Swing compressor — the quiet heart of Daikin
While most manufacturers buy compressors from Panasonic or Copeland, Daikin produces its Swing compressor entirely in-house. It works with fewer moving parts, which reduces vibration, noise and maintenance costs. That’s why the Perfera indoor unit emits just 19 dB — quieter than falling leaves.Coanda effect: no cold draft
Innovative louvers using the Coanda effect direct the air up along the ceiling and distribute it evenly instead of blowing directly at people. The result: a more even temperature throughout the room and no unpleasant “cold wind” in your face. You’ll especially appreciate it while sleeping.Energy efficiency in Bulgarian conditions
Bulgaria is among the EU countries with the fastest-rising electricity prices. For 2025–2026, household tariffs are reaching levels where the choice of energy class directly determines your bill. That’s why investing in an A+++ Daikin air conditioner pays off faster than it seems.| Indicator | Daikin Perfera A+++ | Typical A class (budget brand) |
|---|---|---|
| SEER (cooling) | 8,65 | 5,10 |
| SCOP (heating) | 5,10 | 3,40 |
| Cooling season cost* | ~€ 42 | ~€ 71 |
| Heating season cost* | ~€ 88 | ~€ 132 |
| Annual savings | ~€ 73 | — |
* Calculations for a 12 000 BTU unit, 30 m² room, 750 hours of cooling + 1000 hours of heating per year, tariff €0.19/kWh.
In the example above, the price difference between Sensira and Perfera (about €250) pays for itself in about 3.5 years from electricity savings alone. And a Daikin Perfera will run trouble-free for 15+ years — meaning the remaining 12 years are pure savings.🌡️Unbeatable in a Bulgarian winter: Daikin Comfora and Perfera operate in heating mode down to -20 °C outside and maintain full output down to -15 °C. Winters in Varna rarely drop below -8 °C, so these units will warm your home even on the coldest nights.
Daikin vs. budget alternatives
Customers sometimes ask us: “Why not get something for €300 less?” A fair question. Here’s an objective comparison:✅ Daikin (mid/high range)
- 🔹 In-house Swing compressor with a 15+ year life
- 🔹 Noise from 19–22 dB — practically silent

Frequently Asked Questions About Daikin Air Conditioners
Are Daikin air conditioners suitable for heating in a cold winter?
Yes. The Comfora and Perfera series operate in heating mode down to -20 °C
outside and maintain full heating output down to -15 °C. Winters in Varna rarely reach -10 °C, so these models cover the needs of the Bulgarian climate with a large margin. At temperatures below -5 °C, Daikin is significantly more efficient than most budget brands.
How long does a Daikin air conditioner last?
With proper installation and regular maintenance (cleaning the filters twice a year and a technical inspection every 2 years), Daikin air conditioners last an average of
15–20 years. Many of our customers are still using units installed before 2008.
Can I control the air conditioner from my phone?
Yes, if you have a model from the Comfora, Perfera or Stylish series — the Wi-Fi adapter is built in. With the Daikin Online Controller app (iOS/Android), you can control the unit from anywhere in the world, set schedules and get consumption reports. For Sensira, the Wi-Fi module is an optional extra.
Is Flash Streamer technology safe?
Yes. Flash Streamer generates a plasma discharge inside the unit, not in the room. The technology doesn’t produce significant amounts of ozone and is certified to European standards. It has been tested in independent laboratories and proven to eliminate the flu virus, dust mite allergens and pollen with over 99% effectiveness.
How much does Daikin air conditioner installation cost?
Standard installation (wall mount, line up to 3 m, no additional requirements) is listed on our
installation page. We also offer “air conditioner + installation” package deals — see the
current Daikin models.
