For many years, air conditioning has been surrounded by common misconceptions. One of the most widespread myths is that air conditioners cause colds, allergies or respiratory illnesses. In reality, modern air conditioning systems are designed not only to provide year-round thermal comfort but also to support healther indoor environments.
A well-maintained air conditioner does not make people sick. On the contrary, when serviced regularly and equipped with advanced self-cleaning technologies, it can help improve indoor air quality. Features such as 56°C Steri Clean, available in selected HEIKO wall-mounted air conditioners, actively support hygienic operation by heating the heat exchanger to 56°C for 30 minutes. This process helps eliminate up to 99% of bacteria, viruses, and mould spores that may accumulate inside the unit.
For this reason, more homeowners are paying attention not only to cooling and heating performance but also to technologies that help maintain cleaner, healthier indoor air.
Can Air Conditioning Make You Sick? Facts and Myths
This is one o the most common asked by homeowners considering air conditioning.
The answer is simple: air conditioning itself does not cause illness.
Health problems are usually linked to poor maintenance rather than the system itself. If filters and heat exchangers are not cleaned regularly, dust, bacteria, fungi, and other airborne contaminants may accumulate inside the unit.
Another common issue is setting the indoor temperature far below the outdoor temperature, creating an uncomfortable temperature difference that may affect overall comfort.
Why Does Indoor Air Quality Matter?
Most people spend the majority of their day indoors. As a result, indoor air quality has a direct impact on everyday comfort and wall-being.
Indoor air may contain a variety of contaminants, including dust, allergens, bacteria, viruses, mould spores, and volatile organic compounds (VOCs).
Modern air conditioning systems help reduce the presence of many of these pollutants while maintaining stable indoor temperatures and supporting balanced humidity levels.
This creates a healthier and more comfortable indoor environment, particularly for allergy sufferers, families with children, and people working from home.
How Does 56°C Steri Clean Work?
One of the technologies developed to improve indoor hygiene is 56°C Steri Clean, available in selected HEIKO wall-mounted air conditioners.
Among them is the HEIKO MORA, designed to provide year-round comfort while maintaining a high standard of indoor air quality.
Once activated, the system heats the heat exchanger to 56°C for 30 minutes. This thermal disinfection process helps eliminate bacteria, viruses, and mould spores that may accumulate during normal operation.
As a result, the inside of the air conditioner remains cleaner, supporting both hygienic operation and long-term performance.
For users, this means greater confidence that the air conditioner is delivering not only efficient cooling and heating but also cleaner air every day.
How Does SELF CLEAN Work?
Another important technology available in selected HEIKO models is SELF CLEAN.
This automatic cleaning function is featured in the HEIKO MORA, ROSA White, ROSA Black, and QIRA wall-mounted air conditioners.
During everyday operation, moisture, dust, and airborne particles naturally settle on the heat exchanger. Over time, these deposits may affect system efficiency and indoor air quality.
The SELF CLEAN function automatically initiates a cleaning cycle that helps remove these contaminants from the heat exchanger.
As a result, the unit stays cleaner, operates more efficiently, and requires less manual maintenance between professional service visits.
Although SELF CLEAN significantly supports everyday hygiene, it does not replace regular servicing. Instead, it complements routine maintenance and helps keep the system in optimal condition.
Ionizer – Additional Support for Cleaner Indoor Air
For users who place particular emphasis on indoor air quality, HEIKO QIRA offers an additional advantage.
Unlike other HEIKO wall-mounted models, QIRA features a built-in ionizer designed to help reduce airborne pollutants and improve indoor air quality.
This makes QIRA an excellent choice for allergy sufferers and anyone looking for additional support in maintaining a cleaner indoor environment.
Combined with efficient cooling, heating, and its elegant design, the ionizer makes QIRA a comprehensive solution for year-round comfort.
How Often Should You Clean and Service Your Air Conditioner?
Even the most advanced technologies require regular maintenance.
Air filters should be cleaned according to the manufacturer’s recommendations, especially during periods of intensive use. Clean filters help maintain proper airflow, improve energy efficiency, and support healthier indoor air.
In addition, every air conditioning system should undergo a professional inspection at least once a year.
During a maintenance visit, a qualified technician cleans the key components, checks the system’s operating parameters, and verifies that the entire installation is functioning correctly.
Regular servicing improves efficiency, extends the lifespan of the unit, and ensures hygienic operation throughout the year.
Cleaner Air Starts with the Right Air Conditioner
Today’s air conditioning systems offer much more than cooling during hot summer days. When properly selected and maintained, they contribute to a healthier indoor environment while delivering year-round comfort.
Choosing the right model depends on individual expectations. Homeowners looking for advanced hygiene functions can consider HEIKO MORA, which combines 56°C Steri Clean and SELF CLEAN technologies. Those who prefer compact dimensions and elegant design may find HEIKO ROSA White or ROSA Black an ideal solution, both featuring the SELF CLEAN function. Meanwhile, users who prioritise indoor air quality – especially allergy sufferers – can benefit from the HEIKO QIRA, equipped with a build-in ionizer.
Combined with regular maintenance and professional servicing, these technologies help maintain cleaner indoor air while supporting everyday comfort throughout every season.
