FAQs

How long does a tune‑up take?
Typically 60–120 minutes per system, depending on access, cleanliness, and findings.

Will you add refrigerant if it’s low?
We measure first. If levels are off, we’ll discuss options. Correct charge is only part of the solution—finding the root cause matters.

Do you clean both coils?
Yes—outdoor coil cleaning is standard; indoor evaporator cleaning is performed as accessible and appropriate for the coil design and condition.

Can you help with recurring issues?
Absolutely. As engineers, we troubleshoot hard‑to‑solve comfort and reliability problems, including airflow and control issues.
