Summer is the worst time to discover that your air conditioner isn't working properly. Just when you need it most, it starts to fail: it doesn't cool, blows warm air, or won't even switch on. At Climática Instalaciones, we know all too well the most common summer faults—and how to fix them.
If your air conditioning unit isn’t performing as it should, here are some of the most frequent causes:
1. Dirty Filters
With regular use, air filters get clogged with dust and dirt, reducing airflow and the system’s cooling capacity. It also affects indoor air quality.
- Solution: Clean or replace the filters—ideally before summer begins.
2. Low Refrigerant Gas
Refrigerant gas is essential for cooling the air. If there’s a leak or the level is too low, you’ll notice the air coming out is lukewarm or even hot.
- Solution: Have the system checked and recharged by a certified professional.
3. Lack of Maintenance
Winter has passed and you’ve forgotten about your air conditioning… until the heat returns. Without proper maintenance, units lose efficiency and the risk of breakdowns increases.
- Solution: Annual preventative maintenance to ensure performance and extend the system’s lifespan.
4. Electrical or Thermostat Issues
If the unit doesn't respond, switches off by itself, or doesn’t reach the desired temperature, it could be due to an electrical fault or incorrect thermostat settings.
- Solution: Have the control system and wiring checked by a technician.
5. Blocked or Dirty Outdoor Unit
The outdoor unit (condenser) also needs attention. If it’s blocked by leaves, dust, or debris, it can’t release heat properly and the system will stop cooling effectively.
- Solution: Carefully clean the outdoor unit and ensure good ventilation.
