Heat pump not defrosting — Nicosia, Nicosia
Heat pumps naturally build frost on the outdoor coil in cold weather, and they run automatic defrost cycles every 30–90 minutes to melt it off. When defrost fails, ice encases the entire outdoor unit, blocking airflow and destroying efficiency — you'll notice lukewarm air from the vents and the compressor running constantly. Common causes are a faulty defrost control board or timer, a stuck reversing valve (which flips the system to cooling mode temporarily to defrost), a bad defrost thermostat or sensor, or a refrigerant leak that alters coil temperature. An HVAC technician can diagnose the failed component, replace the board, sensor, or valve, and verify proper defrost cycling before ice damages the compressor.
Waarom dit veel voorkomt in Nicosia
Air conditioning is a year-round necessity rather than a seasonal one: Nicosia is consistently the hottest city in Cyprus (40°C+ summers with no sea breeze), so AC/HVAC failures in July–August are genuine emergencies, and occasional winter frost adds a heating-side load the coastal cities barely see. Commercial buildings drive large-system VRF and chiller maintenance. F-Gas certified technicians (EU regulation) are required for refrigerant handling.

Emergency services in Nicosia respond within 30–90 minutes across the urban core and the Strovolos/Aglandjia/Engomi/Lakatamia suburban belt (faster in the centre, slower in outlying villages and right up against the buffer zone).

As the capital it has the island's deepest contractor pool, but Russian-speaking dispatcher availability is more limited than in Limassol — most operate in Greek and English first.
