Is your AC smelling? Learn why it happens, how to solve it and how to prevent it.

Air-conditioners are deemed as irreplaceable for the comfort they provide us whether at home, at work or in the car. HVAC systems – Heating, Ventilation and Air Conditioning – are built to fulfill our need for comfort in indoor environments, specially inside vehicles and buildings.

Unfortunately, that is not always what happens. How many times do you turn your AC on and that sense of well-being is interrupted by an unpleasant smell? That odor is a warning that something is not working properly and must not be ignored.

How can you find out what is causing this discomfort?

Many HVAC clients believe their air conditioning issues are due to product defects but actually, more than 50% of HVAC issues arise due to a lack of maintenance.

One of the main roles of AC’s is filtering surrounding air, what creates a need of regular cleaning and maintenance of the equipment’s filters.

On the one hand, faulty maintenance or cleaning leads to bad smell and product failure but also the development of bacteria and fungi inside the air-conditioner. This leads to a deterioration of air quality and spread of diseases, namely Legionella, a bacteria that dwells inside the cooling towers of AC’s.

On the other hand, proper cleaning and periodic maintenance lead to a perfect use of your equipment’s features and guarantee you and cleaner and healthier environment.

Although lack of maintenance is one of the main causes of the release of bad odor from AC’s, there are numerous other risk factors. Below you will find each of those risk factors explained and suggestions to reverse it.

  • Drainage

In residential environments, poor installation might be the cause of air-conditioning equipments releasing bad odor. In this case we recommend you to check where the draining tube is pointed at. Sometimes it is pointing at the sewage system, generating that bad smell.

  • External causes

Odor issues related to air-conditioning systems inside cars are usually linked to the accumulation of leaves inside the car’s hollow wall.

  • Humidity

Humidity is one of the biggest causes of bad smell, specially inside cars. Being a poorly ventilated environment, passenger compartments are a favourable environment to the development of bad odor.

Due to the large amount of equipment owned, companies and big facilities opt for a maintenance plan for HVAC systems, making it easier to find and signal issues in HVAC equipment at a very early stage. Here are some maintenance tasks you can include in your plan:

  • Check filtration levels;
  • Analyse contamination state;
  • Check equipment degradation and odor levels;
  • Check hygiene conditions;
  • Check air holes’ cleanliness;
  • Clean ventilation tubes.

Now you understand why holding proper maintenance of your air-conditioning system is key. Regardless of the equipment you are using, taking good care of your AC means taking care of your health and those around you.
