CLOGGED AIR FILTERS
The main purpose of your HVAC system’s air filter is to improve your indoor air quality. However, you need to change or clean your air filters frequently to prevent them from becoming clogged. A clogged air filter can lead to uneven temperatures in different parts of your home and could also damage some of your HVAC system’s components. Check and replace your filters every one to three months.
REFRIGERANT LEAKS
The refrigerant is the main component in your HVAC system that’s responsible for cooling your home. If you can notice reduced airflow and feel like the air isn’t as cool as it used to be, there might be a leak in your refrigerant circuit. In such cases, it’s critical to have a professional technician fix the leak as soon as possible because breathing the refrigerant gases is very harmful. Also, keep in mind that adding more refrigerant will only temporarily fix your cooling problem.
