Rule of thumb: ~330-380 BTU per m². 15-20 m² → 9,000 BTU, 25-30 m² → 12,000 BTU, 35-45 m² → 18,000 BTU, 55-70 m² → 24,000 BTU. Add 20% for south-facing windows, 15% for ceilings above 3 m. For an accurate calc, book a free Formcond on-site survey — +994 51 207 78 89.

A non-inverter unit starts the compressor at full power then switches off — wasting energy and creating temperature swings. Inverter models smoothly vary speed 10-100%, temperature stays stable, energy use drops 30-50%. Inverters cost ~20% more but pay back in 2-3 years on electricity. In 2026, inverter is the standard.

R32 is the next-generation refrigerant: 3× lower global warming potential and 5-10% better cooling efficiency than R410A. From 2025 the EU restricts R410A imports. Choose R32 for any new purchase — parts and service stay easier to find long term.

Typical split: 9-12K BTU — $90-110, 18-24K BTU — $110-130. 5-7 m of pipe and cable included; extra runs $6-9/m. Multi-split from $120. Ducted systems are quoted per project.

Standard 2-year Formcond warranty. Premium models include up to 10 years on the compressor. Conditions: original purchase doc, annual service, mains 220V ±10%. Parts and call-outs are free during the warranty period.

Filter cleaning: every 2-3 months (monthly in summer with heavy use). Full service (evaporator + outdoor unit) — once a year. Formcond pricing starts at 25 AZN. Skipping service reduces efficiency by 15-25% and shortens compressor life by 1-2 years.

For bedrooms, the Mitsubishi Heavy SRK-ZSX-W (Premium Diamond) is the best choice — 19 dB minimum, one of the lowest in the industry. Its 'Night Setback' mode automatically lowers fan speed and adjusts temperature for even quieter operation. The standard SRK-ZSP-W is also good (21 dB), but for ultimate silence go with ZSX. Human Sensor technology directs airflow away from people.

Yes. Mitsubishi Heavy's SRK-ZS-WF series has built-in Wi-Fi; an external Wi-Fi module (~$50) can be added to standard SRK-ZSP models. The 'Smart M-Air' app (iOS / Android) provides: 1) Pre-cool the home before you arrive; 2) Daily/weekly schedules; 3) Real-time energy monitoring; 4) Voice control via Google Assistant and Amazon Alexa. Wi-Fi is standard on the Premium Diamond ZSX series.

5 must-do steps: 1) Clean filters with soap and water; 2) Wipe the indoor unit housing; 3) Clear leaves/dust from the outdoor unit; 4) Flush the drain line; 5) Book a service (Formcond from 25 AZN). Skipping these often results in rattling or vibration in the first hot week.

Yes. Home: silence, design, air purification, weekly schedules. Office: durability, central planning (multi-split or VRF). Restaurant/boutique: ducted (concealed) for aesthetics. Formcond recommends solutions per segment.
