FAQs
What makes an HVAC system “energy-efficient,” and why is that important for Athens?
Energy-efficient HVAC systems use advanced compressors, variable-speed fans, inverter technology, and high Seasonal Energy Efficiency Ratio (SEER) or Coefficient of Performance (COP) ratings to deliver more heating or cooling per kilowatt-hour consumed. In Athens, where summers are long and hot and winters are mild, air-conditioning often runs for many months. An energy-efficient system reduces electricity use by 25-50 %, lowering utility bills and carbon emissions while keeping indoor comfort high.
Which energy-saving heating solutions do you install and how do they work?
We specialize in inverter heat pumps, high-efficiency gas condensate boilers, and hybrid systems that automatically switch between electric and gas depending on outside temperature. Heat pumps extract ambient heat from outdoor air—even at 0 °C—compress it, and deliver it indoors, achieving COP values of 3–5 (every 1 kW of electricity yields 3–5 kW of heat). Condensing boilers reuse exhaust heat to reach efficiency levels up to 98 %. Hybrid setups maximize whichever source is cheaper at the moment, guaranteeing comfort and savings.
How much can I expect to save on utility bills after upgrading?
Savings depend on the size of your home, current system age, and your tariff, but our Athens clients typically report: • 30–45 % lower summer electricity costs after switching from fixed-speed units to inverter A+++ ACs. • Up to 50 % reduction in winter heating costs when replacing oil burners with air-to-water heat pumps. A free on-site assessment allows us to model your exact annual consumption and estimate payback, which is commonly 3–6 years.
Are there government incentives or subsidies in Greece for installing high-efficiency HVAC equipment?
Yes. Under the “Eksikonomo–Autonomo” and updated “Eksikonomo Kat’ Oikon” programmes, homeowners can receive 40–75 % subsidies for heat pumps, efficient boilers, smart thermostats, and insulation upgrades. Additional tax deductions of up to 40 % are available when energy class improves by at least three levels. We handle the paperwork, energy studies, and submission to help you secure every euro you are entitled to.
How long does installation take and will it disrupt my routine?
Most split or multi-split inverter AC systems are installed within one day. Air-to-water heat pump retrofits to existing radiators usually take 1–2 days, while full hydronic floor heating projects may take up to a week. We schedule work around your availability, use protective floor coverings, and test each circuit before leaving, so disruption is minimal and you can typically use the main living areas the same evening.
What maintenance does my new high-efficiency system require?
Even the best systems need periodic care to maintain peak efficiency: • Clean or replace air filters every 2–3 months in cooling season. • Annual professional servicing: refrigerant pressure check, coil cleaning, electrical inspection, and software updates. • Heat pumps: winter defrost cycle calibration and condensate drain check. • Smart thermostat firmware updates and optimisation of schedules for seasonal changes. Regular maintenance preserves manufacturer warranties, prevents energy waste, and extends equipment life well beyond the 15-year mark.
