Frequently Asked Questions
When should I schedule my AC tune-up?
Spring is ideal — before the cooling season begins. This ensures your system is ready when temperatures rise and gives us time to address any issues found.
What's included in an AC tune-up?
Our tune-up includes checking refrigerant levels, cleaning condenser and evaporator coils, inspecting capacitors and contactor, checking electrical connections, testing thermostat operation, and verifying proper airflow.
How can I tell if my AC needs more than a tune-up?
If your AC is making unusual noises, not cooling adequately, cycling frequently, or has visible ice on the refrigerant lines, you may need a repair in addition to maintenance.
Does annual AC maintenance really make a difference?
Yes. Studies show properly maintained AC systems use 15-20% less energy and last 5-10 years longer than neglected systems. The tune-up pays for itself in energy savings.
