Is this normal for a tankless water heater?

Water temperature has gone way down in the past few weeks. Is this something I can diagnose myself?

I have a tankless water heater that is probably from the mid 90s (AquaStar). About a few weeks ago, I noticed that my shower was not getting as hot as it used to and it was getting cold faster. I tested the vanity sink and at full heat, I would only describe it as "mildly warm".
This indicates to me an issue with the water heater rather than the showerhead or faucet. Question: this loss of heat, is it something that an average homeowner could diagnose? Or should I call around and get a plumber out here?
If it sounds like something specific has gone wrong, how much should I expect to pay to replace it?
