Question:

I have an Apollo direct vent heating system, it is blowing cold air for the heat. What should I check?

The hot water is working, I just want to know what else to check, if there is a valve that needs to be turned or if my temp isn't set correctly.

Answer:

Hello Tammy. Your question has been unanswered for 2 days. My best guess is because it needs a few more details. Is your installation a boiler, feeding a heat exchanger to forced air? How long since you witnessed it functioning? Has it been worked on?
