Short answer
If you have just moved into an Israeli apartment, four things are worth knowing about the air conditioning. First, identify the system: a white box on the wall is a split (מזגן עילי); ceiling vents mean a concealed mini-central (מיני מרכזי). Second, assume it has never been deep-cleaned unless you have an invoice proving otherwise — this is the norm, not the exception. Third, routine cleaning is normally the tenant's responsibility under an Israeli lease, while repairs are the landlord's. Fourth, budget ₪350 per split unit or ₪450+ for a mini-central, once a year, before summer. Photograph the inside of every unit on move-in day.
| First thing to do | Photograph inside every AC unit on move-in day, before use |
|---|---|
| Split unit in Hebrew | מזגן עילי (mazgan ili) — white box on the wall |
| Mini-central in Hebrew | מיני מרכזי (mini merkazi) — ceiling vents, hidden machine |
| Air duct in Hebrew | תעלה / שרשורית (te'ala / shar'shurit) |
| Cleaning in Hebrew | ניקוי מזגן (nikuy mazgan) |
| Electricity company | Chevrat Hashmal (חברת החשמל) — bills arrive every two months |
| Who pays for cleaning | Normally the tenant; repairs are normally the landlord |
| Annual cost to budget | ₪350 per split unit · ₪450+ for a mini-central |
| When to book | March–April, before the May–June peak |
| Tax invoice | חשבונית מס — ask for it, especially for relocation reimbursement |
| English-speaking service | Yes — Sayeret HaMazganim handles quote, technician and invoice in English |

There's a gap in the standard aliyah and relocation briefing. You get told about Bituach Leumi, about opening a bank account, about the arnona. Nobody sits you down and explains the machine that will run for five months a year, consume a large fraction of your electricity bill, and circulate the air you sleep in.
So: a short version of what a long-time Israeli resident knows and you probably don't.
Look up. If there's a white rectangular box mounted high on a wall in each room, those are split units (מזגן עילי) and you have one per room. If instead there are flat vents set into the ceiling and a single thermostat on a wall in the hallway, you have a mini-central (מיני מרכזי) — one machine hidden above a lowered section of ceiling, feeding several rooms through ducts.

This sounds cynical and it is simply accurate. Rental units in Israel change hands repeatedly and air conditioner servicing falls into the gap between outgoing tenant, landlord and incoming tenant. A large share of the systems we open in rented apartments have never had a deep clean, and in mini-centrals that regularly means ten years or more.
The practical consequence: don't wait for a smell. Get it cleaned in your first months, then once a year after that.
Before you switch anything on, open the flap on each split unit and take a photo of the filters and the coil behind them. Two minutes of work. It establishes the condition at handover, which settles essentially every future conversation with a landlord about who owes what — and if they're visibly filthy, it's a strong, non-confrontational basis for asking the landlord to cover the first clean.

Even if you deal with us entirely in English, these come up constantly — in leases, in WhatsApp groups, when a neighbour gives you a recommendation:
₪350 per split unit, or from ₪450 for a mini-central plus ₪249 a duct, once a year. For a three-bedroom apartment with three split units, that is ₪749 a year. Against an electricity bill that a dirty system inflates by a fifth to a third for five months of the year, it is one of the few household expenses in Israel that reliably pays for itself.

We would rather cite research than make claims. These are the figures behind what we do.
A dirty condenser coil can increase compressor energy consumption by up to 30 percent.
U.S. Department of Energy, cited in Buildings, "Clean HVAC System Coils Save Energy"As little as 0.042 inches (about 1 mm) of fouling on a coil has been measured to cut system efficiency by 21 percent.
U.S. EPA study, as reported in HVAC industry literatureIndoor levels of common organic pollutants run two to five times higher than outdoors — and occasionally more than 100 times higher.
U.S. EPA, "The Inside Story: A Guide to Indoor Air Quality"People spend roughly 90 percent of their time indoors, which is where the air an air conditioner circulates actually matters.
U.S. EPA, Report on the Environment: Indoor Air QualityCoil fouling and its energy cost is a documented research area — see also Lawrence Berkeley National Laboratory, "Dirty air conditioners: Energy implications of coil fouling." Figures above are from United States agencies; Israeli conditions, with higher year-round humidity than most of the US, are generally harder on equipment rather than easier.
