Licensed HVAC Services in Highland, CA 92346 - 4 Points A/C and Heating

In Highland's climate, with dust and seasonal allergens, we recommend checking your standard 1-inch filter monthly and changing it every 1-3 months. If you have pets or allergies, you may need to change it more frequently. A clean filter is crucial for protecting your AC coil, maintaining airflow, and keeping your energy bills down.

If your AC is running constantly but not cooling your Highland home effectively, or if you notice a spike in your energy bill, a dirty evaporator coil could be the culprit. Reduced airflow from your vents and ice forming on the refrigerant lines are also common signs. Regular professional maintenance includes a thorough coil cleaning to prevent these issues.
