Vaillant Air Conditioner Sales and Professional Installation Across Türkiye
Sales, site survey and installation of Vaillant Pure, Pro and Multi series air conditioners, all from one team. We serve the whole of Türkiye and commission every unit under the Vaillant warranty.
Air conditioning is no longer just about summer. It keeps you cool through the humid, sticky months and doubles as an economical source of heating in the mild shoulder seasons. A well-chosen, well-installed unit shapes both your comfort and your electricity bill for years to come — and as an authorized Vaillant dealer, we make that decision easy.
With us the whole process runs through one team: we listen to what you need, carry out a site survey where necessary, work out the right capacity for your room together and complete the installation professionally.

Frequently Asked Questions
Square meters are the starting point, but facade orientation, the size of your windows, insulation and which floor you're on can shift the answer considerably. An undersized unit runs flat out and burns through electricity; an oversized one keeps cycling on and off without ever dehumidifying properly. That's why we recommend confirming the capacity during a site survey.

Istanbul summers aren't just hot — they're humid. When the thermometer reads 30, the humidity makes it feel far hotter, and the evening breeze rarely makes it indoors. In this climate an air conditioner earns its keep by pulling moisture out of the air as much as by cooling it. So when choosing a unit in Istanbul, look beyond raw cooling power to dehumidification performance and the efficiency class. Vaillant air conditioners strike that balance with high efficiency and quiet operation.
Getting the capacity right is the most critical part of the decision. An undersized unit runs at full power constantly, never quite gets the room to the temperature you want and wastes electricity. An oversized unit hits the target fast, shuts off, then restarts in short bursts — never removing enough humidity, leaving you with a clammy, uncomfortable kind of cool. Square meters are a good starting point but not enough on their own: facade orientation, glazing, ceiling height, insulation and the floor your apartment is on all push the number up or down. For a deeper dive, see our Istanbul air conditioner buying guide.
Installation matters as much as the unit you choose. Vacuuming the copper lines, leak testing, giving the drain line the correct slope and positioning the outdoor unit where it gets proper airflow — each of these directly affects efficiency and lifespan. Skip the vacuuming and residual moisture slowly erodes cooling performance; get the drainage wrong and it announces itself as a water stain on your wall. In Istanbul's apartment buildings the outdoor unit's location often runs into facade rules and building management decisions too — we work through those details with you at the survey stage and put together a trouble-free installation plan.
The Vaillant air conditioner family offers three series. Pure and Pro are split models designed for a single room or living room, differing in features and comfort options. The Multi series connects several indoor units to one outdoor unit to serve multiple rooms at once — a practical answer for Istanbul apartments where there's simply no space on the balcony or facade for a separate outdoor unit per room. Browse the models in our product catalog, and if you're torn between options, ask us on WhatsApp.
One overlooked advantage of inverter air conditioners is heating mode. In heating mode the unit works like an air-source heat pump, drawing heat from the outdoor air and moving it inside — one of the most efficient ways to heat with electricity in Istanbul's mild winters. In the shoulder seasons you can often stay comfortable on the air conditioner alone, without firing up the boiler at all. If you'd like a single system to heat and cool your whole home, see our heat pump solutions; for gas-fired primary heating, see our boiler installation service.
