In Israel and Palestine, air conditioners run for long stretches. Routine maintenance isn't a luxury — it's the difference between a reasonable electricity bill and a sudden breakdown in the middle of a heat wave.

When do you need maintenance?

  • Before summer starts: filter cleaning and general check
  • If the AC drips water into the room
  • If cooling weakens despite running at max
  • If you hear unusual sounds (clicking, squealing)
  • If more than a year has passed since the last professional cleaning

What does routine maintenance include?

The technician removes and cleans filters, inspects the condenser and evaporator, checks gas levels, and cleans the drain line. Cleaning and servicing a split AC usually costs 250–400 ₪. Gas refill — if needed — runs 350–600 ₪ depending on gas type and amount.

Cost of new installation

Installing a standard split AC ranges from 700–1,200 ₪ depending on line length and access difficulty. The price may not include extra electrical work — ask explicitly.

Can you clean it yourself?

Cleaning external filters every two months is simple and extends lifespan. But cleaning internal units and chemical gas checks require a licensed technician — gas is under pressure and a small mistake can cost dearly.

Signs the AC needs a technician immediately

  • Burning smell when starting
  • Ice forming on the indoor unit
  • AC keeps shutting off and restarting (short cycling)
  • Heavy water leak

Tips to reduce costs

One annual service is cheaper than replacing a burned-out compressor. Keep ventilation space around the outdoor unit. Close windows properly when running. Don't set temperature below 22°C — a large gap with outdoors strains the unit.

Choosing the right AC technician

Make sure the technician works on your brand or has general split experience. Ask about warranty on refill and cleaning. Some offer an annual package (maintenance + emergency priority) — worth it if you have multiple units.

Electricity consumption and AC

A dirty or low-gas AC uses 20–40% more electricity. Filter cleaning alone can improve performance immediately. Place the unit away from heat sources (sunny window, heater) — it misleads the sensor and extends run time.

AC types on the market

Split (indoor + outdoor unit) is most common in apartments. Window units are cheaper but harder to install in modern windows. Multi-split systems serve several rooms — suited for villas. Ask the technician about cooling capacity for your room size — too small overworks, too large wastes power.

When is repair not worth it?

If the AC is 12–15 years old and needs repeated compressor or gas work, replacement may be more economical. Compare three repair costs against a new energy-efficient unit. An honest technician will tell you when it's not worth it.

Bottom line

Annual AC maintenance (250–400 ₪) is a small investment compared to buying a new unit or paying double electricity. If you're unsure about your unit's condition, schedule a check before peak summer when prices rise and appointments fill up.
