Moving into a house with an unknown HVAC history

We bought a house, but we don't know when the air conditioning and ventilation were last serviced. The system is working, but we have our doubts. Should we have it checked immediately after moving in?

I would definitely recommend having the system checked. When we moved, I contacted https://acustomerfirstac.com/ , and it was the right decision. The specialists conducted a full diagnosis, identified worn parts and contamination that could have led to breakdowns in the summer. Some of the problems were fixed immediately, and the rest were scheduled for later. This gave us confidence that the system is safe and will not fail at the hottest moment.
