Why airconditioning cleaning is essential before the summer holidays

The summer holidays are just around the corner. Many motorists and camper drivers therefore quickly check tire pressure, oil levels, and coolant. However, one important component is often overlooked: the air conditioning system.

Especially during long holiday drives, a properly functioning air conditioner is indispensable for comfort and a pleasant interior climate. But did you know that a dirty air conditioning system can not only cause unpleasant odors but also affect the air quality in the vehicle?

What happens inside an air conditioning system?

During the use of the air conditioning, condensation (moisture) forms inside the system. Combined with dust, pollen, and other contaminants, this creates an ideal environment for bacteria, molds, and yeasts. These microorganisms can accumulate in the ventilation and air conditioning system, causing the familiar musty smell that many drivers recognize as soon as the air conditioning is switched on.

In addition to unpleasant odors, contamination can also lead to reduced fresh airflow and a decrease in comfort while driving. This becomes noticeable quickly, especially during hot summer days. Want to learn more about this? Click here.

Why air conditioning cleaning is important before departure

A clean air conditioner contributes to:

Fresher air in the interior
Less chance of musty odors
A more pleasant driving experience during long journeys
Better air quality for the river and passengers
Improve efficiency in the air conditioning system

For vacationers who are on the road for a long time to their destination, this can make a significant difference in comfort.

More than just masking odors

Traditional air conditioning cleaners often focus on removing odors or disinfecting surfaces. However, this is only a temporary solution.

Tec4 Airco Cleaner takes a different approach. The formula combines environmentally friendly cleaning agents, enzumes, and probiotic bacteria. These probiotics not only help remove surface contamination but also target the biofilm that underlies many contamination problems in air conditioning systems.

When is an air conditioning cleaning necessary?

An air conditioning cleaning is certainly recommended when:

A musty or unpleasant odor comes from the ventilation
The vehicle has not been used intensively for a long time
The holiday season is approaching and the system will be used frequently again
It has been more than a year since the air conditioning system was cleaned

Tec4 recommends cleaning the air conditioning system at least once a year to maintain optimal air quality and system performance.

Ready for a fresh start to your holiday?

A holiday doesn’t start at the destination, but as soon as you step inside. By paying attention to the air conditioning system before departure, you ensure a comfortable journey and a more pleasant interior climate for all occupants.

A minor service can therefore make a big difference during your holiday journey.

FAQ – Air Conditioning Cleaning in Electric Vehicles (EVs)

Unlike traditional vehicles, the air conditioning system in electric vehicles (EVs) performs a crucial technical function. In addition to cabin cooling, it plays a key role in the thermal management of the battery and power electronics. Regular air conditioning cleaning/service is therefore essential for maintaining range, efficiency, and service life.

Functioning of the air conditioning system in EVs and hybrid cars.

In modern electric and hybrid vehicles, the HVAC (Heating, Ventilation, and Air Conditioning) system is closely linked to thermal management. It helps keep the temperature of critical components, including the battery pack and power electronics, within safe and efficient limits.

This system regulates the temperature of the battery pack, which functions optimally within a limited temperature range. If the temperature rises too high, it can lead to accelerated wear, reduced performance, and in extreme cases, permanent damage.

Poorly functioning air conditioning can also reduce the vehicle’s efficiency. When the system has to work harder due to a lack of refrigerant or contaminated components, it consumes more energy. In electric vehicles, this directly results in a reduced range per charge.

A stable temperature is essential because:

high temperatures accelerate battery degradation
inefficient cooling can lead to power loss
thermal stress shortens the life of battery components

An optimally functioning air conditioning system helps to mitigate these risks and supports overall vehicle performance.

Contamination reduces efficiency and increases energy consumption

During operation, bacteria, mold, dust, and organic contamination accumulate in the evaporator and ventilation ducts of the air conditioning system. This contamination forms an insulating layer that reduces heat transfer. As a result, the electric compressor has to work harder to deliver the same cooling performance.

For electric vehicles, this has direct consequences:

higher energy consumption of the HVAC system;
noticeable reduction in range;
increased load on the compressor and components;
less efficient temperature control of the battery and electronics

Even small efficiency losses in electric vehicles can have a measurable effect on driving performance and energy consumption.

Preventative cleaning/service prevents wear and expensive repairs

Preventative cleaning of the air conditioning system helps remove contamination and restore optimal operation. This results in:

optimal heat transfer in the evaporator;
more efficient operation of the electric compressor;
stable performance of thermal management systems;
extended lifespan of HVAC components;
maintenance of maximum energy efficiency.

In addition, a clean air conditioning system improves cabin air quality and prevents odor formation.

Air conditioning service/cleaning essential part of EV service

With the continued electrification of the vehicle fleet, it’s becoming clear that air conditioning service plays a crucial role in the technical reliability of electric and hybrid vehicles. Regular cleaning helps minimize energy loss, protects critical components, and supports optimal vehicle performance.

Through preventative service with solutions like Tec4 Airco Cleaner, workshops and vehicle owners can contribute to a longer lifespan, higher efficiency, and maximum performance of electric vehicles.
