    Heil 92% H9MPDO75F12B Gas Furnace
    I had a Heil Gas Furnace installed and from the first day I notice that when the blower came on the air was on the cool side. After about 1 to 2 minutes the air became a little bit warmer but never got hot. My question is this normal or do I have a problem? Please let me know as soon as possible so I could have it corrected. Thank you, Jack

    I would check with the installer. Is it still fairly warm outside? As long as it isn't too cold, the furnace will not fire at its full rate to improve efficiency. The blower may be set too fast, pushing the air through before it becomes warm enough. The blower only has so many different speeds. It is possible that even on the slowest speed, the air may not be as warm as you are used to at the lower firing rate. The installer may or may not be able to improve it.
