From the steamy heat of an Athenian summer to the occasional winter chill, your comfort depends on a system that works smarter, not harder. HEP designs and installs high-efficiency HVAC solutions that balance temperature control with reduced energy consumption, trimming utility bills without sacrificing performance. Our technicians analyze your space, recommend cutting-edge equipment, and fine-tune every component so you enjoy consistent comfort year-round—while shrinking your carbon footprint in the birthplace of sustainability ideas.
Equally important, we focus on ventilation and air quality to ensure the air you breathe is as refreshing as the Parthenon breeze. Advanced filtration, humidity regulation, and whisper-quiet fresh-air systems remove pollutants and allergens, creating healthier living and working environments. Whether you’re renovating a neoclassical townhouse or outfitting a modern office, HEP delivers tailored solutions that keep Athens comfortable, efficient, and invigorating—one perfectly conditioned breath at a time.
FAQs
Why is investing in an energy-efficient HVAC system especially important in Athens?
Athens experiences long, hot summers, mild winters, and elevated electricity prices. An energy-efficient system lowers cooling and heating costs by 20–40 %, reduces strain on the national grid during heat waves, and cuts CO₂ emissions—an increasingly important concern as Greece moves toward its climate-neutral targets for 2050.
Which efficiency ratings should I check when buying new equipment?
For cooling, look for a Seasonal Energy Efficiency Ratio (SEER) of at least 16, though SEER 18–20 models provide the best savings in the Attica climate zone. For heating, consult the Heating Seasonal Performance Factor (HSPF) or Coefficient of Performance (COP); heat pumps with a COP ≥ 4 and HSPF ≥ 9 are recommended. Also review the EU energy label—choose A+++ where budget allows.
Does a heat-pump solution make sense in the relatively mild winters of Athens?
Yes. Air-source heat pumps are extremely efficient in temperatures above 5 °C, a range that covers most winter days in Athens. One unit can both heat and cool, eliminating the need for separate boiler and A/C systems. Inverter technology further boosts efficiency by modulating output instead of cycling on/off, saving up to 30 % in annual energy use.
How can I improve indoor air quality while staying energy-efficient?
1. Install a mechanical ventilation system with heat recovery (HRV/ERV). It exchanges stale indoor air with fresh outdoor air while capturing up to 80 % of the thermal energy. 2. Upgrade to MERV 13 or HEPA filters in air handlers to trap pollen and fine particles common in Athens’ urban atmosphere. 3. Maintain 40–60 % indoor humidity using dehumidification in summer and humidification in winter; this discourages mold and improves comfort. 4. Schedule duct cleaning every 3–5 years to prevent dust buildup and maintain airflow.
What routine maintenance keeps my system running efficiently?
• Change or wash filters every 1–3 months during heavy use. • Clean outdoor condenser coils at the beginning and end of summer to remove dust and coastal salt deposits. • Check refrigerant charge annually; low levels cut efficiency by up to 15 %. • Inspect and seal ductwork—leaks can waste 20 % of conditioned air. • Service the heat-recovery ventilator twice a year: clean cores, fans, and condensate drains. Regular maintenance can extend equipment life by 5–7 years and preserve factory-rated efficiency.
Can smart thermostats and zoning really lower my energy bills?
Absolutely. Smart thermostats learn your schedule and adapt setpoints automatically, typically delivering 8–12 % energy savings. Zoning uses motorized dampers and multiple thermostats to condition occupied rooms only; combined with variable-speed compressors, it can cut consumption by 20–30 % in larger Athens homes where upper floors overheat in summer.
