What temp should the air coming out of vents be when heater is on?

HVAC replaced in May and this weekend was the first time using the heater. Well the temp inside the house doesn’t warm up and the air coming out of the vents is only 69°-70°.
Is this normal for newer units? Can’t be.

Maybe over 90-over 100. Sounds like you have an issue.

I was told over 90 and up to 110 when I replaced our HVAC. Never measured it.

What’s your heat setting and what is the temp outside? Most along the gulf coast have heat pumps with a back up heat strip. If it’s too cold outside the heat pump can’t keep up and you need to go to ‘emergency heat’ to get warmer temps which kicks on the electric heat strip. Its somewhat ridiculous it’s called em or emergency heat as many don’t understand what that means and it’s not an actual ‘emergency’.
If you have nat gas you may have a gas heat system but that’s much more rare along the gulf coast.

It’s an electrical system and I’m near Baton Rouge so not good but cool enough for the house to have a chill.

Do you think it’s possible that the tech only connected a few of the heat strips to the normal operating unit and that turning on the auxiliary heat would cause the rest of them to kick on? We had the option to connect 8 strips on our unit but we chose to connect 5 if I remember correctly. He said it would be overkill here in our climate for 90% of winter. The aux/emergency heat setting turns them all on and causes my electric bill to get jiggy with it.

I had a system in a rental home installed and they set it up wrong and didn’t have the electric strips/ em heat set up. I can’t remember the details it’s been awhile. But not surprised if something simple like that was the issue considering it was installed in the summer.

I sure hope that’s all it is. Unfortunately I vaguely remember them testing the heat setting after instillation and it got hot.

Had that happen to me on new construction. The intellectually challenged installer wired the strips backwards - was only getting 10kw heat from a 15 kw machine.

Full HVAC replacement?
My old home still has a gas furnace that we left in place when putting in a new AC unit. Our heater was doing the same thing a few days ago. I went up there and saw the pilot light was out. Not sure what knocked that out as it has never happened before.
If you are electrical, then I do not know exactly what your issue could be.
EDIT: I see its electrical now

nat gas here. 100* at least.

Had ours replaced at the end of March and when I turned on the heater for the first time the blower came on but the element did not so it was just recycling air. Had a tech come out and check but wasn't home and my wife didn't ask for an explanation. I think it is on a separate breaker in the attic.
Speaking of, does it make sense to completely cut power to the heater during the summer? Never though about it before but I guess it kinda makes sense.

Negative, that’s not how electric heat works. If you only connect half the heating strips, it will simply run twice as long to heat your house. I would get them all connected so the unit works the way it is designed to work.
I’ll bet you find that some that were supposed to be working are not working, too.

I assume you’re asking about the air handler? If so, how would you move air in the summer if the air handler has no power. Also, if it’s an air handler, that’s where your evaporator coil is located. You need the AHU powered up to cool your home.

Gas or electric?
Gas will be hotter. Electric isnt really hot and has to run a lot to get it to temp.
