How often should I clean my AC?

Most households should clean their AC every 6–12 months. For homes with pets, allergies, or heavy usage, every 4–6 months is recommended.

What are the signs my AC needs cleaning?

Common signs include weak airflow, bad smell, water leakage, higher electricity bills, loud noise, or slower cooling performance.

How long does an AC cleaning service take?

A standard split-unit cleaning usually takes 45–90 minutes, depending on the condition of the unit and whether a deep chemical wash is required.

Is chemical cleaning safe?

Yes - when done by trained technicians. We use safe, non-corrosive solutions and rinse thoroughly to protect your unit and ensure clean, healthy airflow.

Will AC cleaning fix the “not cold” problem?

If dirt or clogged coils are causing the issue, cleaning will significantly improve cooling. If the problem is related to gas levels or damaged parts, a repair may be needed.

Do I need to be home during the service?

Yes, someone should be present to provide access and review the work afterward, but you don’t need to supervise the entire process.
