Frequently Asked Questions
Answers to the most common questions about air conditioners, installation, and maintenance.
What BTU do I need for a 25 m² room?
For a standard 25 m² room up to 2.7 m ceiling with average insulation, the recommended power is around 9,000 BTU (~2.5 kW). For south-facing rooms or weak insulation, consider 12,000 BTU. Use our calculator for a more precise recommendation.
How much does air conditioner installation cost?
Standard installation of a split AC up to 12,000 BTU starts from €90 for the basic package (piping up to 3 m, mounting, test run). Additional pipe length, concealed routing or tall walls are charged separately. Contact us for a precise quote after purchase.
What is the difference between split and multi-split AC?
A split AC has 1 indoor unit connected to 1 outdoor — for a single room. A multi-split has 2-5 indoor units connected to 1 common outdoor — saves facade space and is cheaper than installing several separate splits. Suitable for apartments and houses with multiple rooms.
What does energy class A+++ mean?
Energy class A+++ is the highest class under the EU 2013 standard — the AC consumes 30-40% less power than class A at the same output. Real savings for a 25 m² room used 6 h/day ≈ €100-150/year vs class A. We recommend class A++ or A+++ for any new AC.
How often should AC maintenance be performed?
We recommend maintenance once a year — before the active summer season (April-May). Includes: filter and fan disinfection, refrigerant check, condensate cleaning, mode test. Price: €30-50 for indoor + outdoor unit. For year-round active use — twice a year.
What is the warranty on air conditioners?
Standard warranty is 2 years for private customers (per consumer protection law) and 12 months for business customers. Daikin, Mitsubishi and Toshiba offer extended warranty up to 5 years upon registration in their portal after installation. The warranty covers manufacturing defects but not damage from misuse or natural disasters.
Can an AC heat in winter?
Yes — all modern inverter ACs heat efficiently. The SCOP coefficient indicates heating efficiency: SCOP 4 means for 1 kWh of electricity the unit produces 4 kWh of heat — about 3x cheaper than electric heating. At outdoor temperatures below -10°C efficiency drops. Hyper-inverter models work down to -25°C.
What should I consider when choosing an AC?
Main criteria: 1) Power (BTU) — matched to area, orientation, insulation. 2) Energy class — minimum A++. 3) Noise level — under 25 dB for bedroom. 4) Manufacturer — Daikin, Mitsubishi, Toshiba, LG offer best reliability. 5) Wi-Fi control if relevant. 6) SEER/SCOP coefficients for real operating costs. 7) Warranty and service availability in your area.
