Frequently Asked Questions

An AC tune-up includes inspecting and cleaning components, checking refrigerant levels, tightening electrical connections, and ensuring efficient, safe operation.

If your system is over 10–15 years old, frequently breaks down, or is inefficient, replacement may be more cost-effective. Otherwise, quality repairs can extend its life.

We recommend servicing your AC system at least once a year — preferably in spring — to maintain performance, catch small issues early, and extend equipment life.
