What air conditioning really costs for a holiday apartment in Bulgaria: purchase, installation and yearly upkeep

Planning air conditioning for your apartment in Nessebar, Sunny Beach, Ravda or Sveti Vlas? Here is a realistic breakdown of every cost - from buying the unit and installation to annual servicing - plus tips on where not to overpay.

The three parts of the budget

The total investment in air conditioning for a holiday property consists of three parts:

  • Buying the unit - a one-off cost that depends on class and capacity.
  • Professional installation - one-off, and critical for the lifespan of the system.
  • Yearly maintenance - a small but regular cost that protects the warranty and efficiency.

How much does the unit itself cost

For a standard 40-70 m² apartment, a 9,000-12,000 BTU unit is usually enough. As a guide:

  • Entry level (Gree and similar) - around EUR 500-750.
  • Mid range (Fuji Electric, Toshiba) - around EUR 750-1,100.
  • Premium (Daikin, Mitsubishi Electric / Heavy) - around EUR 1,100-1,800.

Tip for seaside properties: investing in a higher class with anti-corrosion coating on the heat exchanger pays off - salt air ages cheap outdoor units much faster.

Installation - once, but done properly

Standard installation (up to 3 m of pipe run, one wall hole, vacuuming, start-up and test) is usually in the range of EUR 150-250. Extras apply for longer pipe runs, difficult facade access, a lift or removal of an old unit. See our detailed article on installation prices in 2026.

Annual servicing - the most underestimated cost

Maintenance (cleaning filters and units, checking refrigerant and drainage) costs roughly EUR 30-60 per year and is especially important by the sea. A dirty air conditioner uses 10-30% more electricity and breaks down more often. If you rent the apartment out, a clean AC is also a matter of guest reviews.

Example total for 5 years

  • Mid-range 12,000 BTU unit: ~EUR 900
  • Standard installation: ~EUR 200
  • Servicing 5 × EUR 45: ~EUR 225
  • Total for 5 years: ~EUR 1,325, or about EUR 22 per month.

Figures are indicative; the exact quote depends on the property and the model.

Frequently asked questions

What capacity do I need for a holiday apartment?
Roughly 9,000 BTU for rooms up to ~40 m² and 12,000 BTU for ~50-70 m². South-facing rooms with large windows need a reserve - the exact recommendation follows a site survey.
Is Wi-Fi control worth it for a holiday property?
Yes. With a Wi-Fi module you can switch the unit on before you arrive, check its status remotely and make sure it is not running pointlessly while you are away.
Can you install and service the unit while I am not in Bulgaria?
Yes. We work with a key left with neighbours, the building manager or your property management agency, and we send photos/video before and after the work.
