FAQs
What are the main climate challenges in Athens that affect heating, air-conditioning, and indoor air quality?
Athens experiences very hot, dry summers with temperatures often exceeding 35 °C, mild but occasionally damp winters, high urban pollution levels, and Saharan dust episodes. These conditions place heavy demand on cooling systems, require dehumidification control in winter, and make high-efficiency filtration and ventilation essential for keeping indoor air free of airborne particles and pollutants.
Which HVAC system is most energy-efficient for Athens’ climate?
For most homes and small businesses in Athens, a modern air-source heat pump with inverter technology is the best all-round solution. It delivers efficient cooling in summer, heating in winter down to about –5 °C, and can be combined with a heat-pump water heater. When sized and installed correctly, seasonal energy efficiency ratios (SEER) of 7–9 and seasonal coefficient of performance (SCOP) of 4–5 are achievable, cutting annual energy bills by up to 40 % compared to older split or boiler systems.
How important is ventilation in a city with high outdoor pollution like Athens?
Ventilation is critical for removing indoor contaminants such as CO₂, VOCs, and moisture, but must be carefully managed to avoid bringing in pollutants. Balanced mechanical ventilation with heat recovery (MVHR) is recommended: it supplies filtered outdoor air, extracts stale indoor air, and transfers up to 90 % of heat between the airstreams to minimise energy loss. High-efficiency particulate filters (F7–F9 or ePM1 70 %) capture fine dust and diesel soot common in Athens traffic corridors.
What indoor air quality (IAQ) features should I look for in a new HVAC installation?
Key IAQ features include: (1) multi-stage filtration—prefilter plus fine particulate filter and optional activated carbon layer for odour/gas removal; (2) demand-controlled ventilation using CO₂ or VOC sensors to adjust airflow; (3) ultraviolet-C or photocatalytic disinfection modules to limit microbial growth on coils and ducts; (4) condensate management to prevent mould; and (5) smart controls that display temperature, humidity, and air-quality data in real time.
How often should HVAC equipment be serviced in Athens, and what does maintenance involve?
Professional maintenance is recommended twice a year—once in spring before the cooling season and once in autumn before heating. Typical tasks include: cleaning or replacing air filters, checking refrigerant charge and pressures, cleaning coils and drain pans, inspecting electrical connections, lubricating moving parts, testing thermostat and control operation, and verifying airflow through ducts or indoor units. Regular service preserves efficiency, improves air quality, and extends equipment life.
Are there any Greek incentives or regulations I should know about when upgrading my HVAC system?
Yes. The Greek ‘Exoikonomo–Autonomo’ programme provides subsidies of 40 %–75 % for energy-saving home upgrades, including heat pumps, high-efficiency air conditioners, and MVHR systems. New buildings must meet the 2021 KENAK energy performance standard, which mandates minimum SEER/SCOP values and requires mechanical ventilation with heat recovery in nearly zero-energy buildings (nZEB). Always ensure your installer supplies an Energy Performance Certificate (EPC) and product declarations to qualify for incentives and comply with regulations.
