Amana 16 seer heat pump is not heating just blowing cold air just installed in july

The cold that you describe may be just unconditioned air? If you are certain you can hear the comp operating for a couple of minutes, and then the heat starts, I would guess it is a reversing valve issue if it's a heat pump and it probably is. Or the control board acting up. I've had a lot of issues with the boards in the Amanda PTAC units. I can't remember how to configure it, but if you Google "Amanda ptac configuration", there is a lot of info online. May try a reset method first. Hope this helps!

410 a runs at a much higher pressure then r-22. that is still very high. it would take a temperture over 150 degrees to produce it on a idle system.

E5 indicates excessive temp. of the outside coil if on cooling, OR excessive temp of the inside coil in.

Try cleaning it (them if inside one too), with dishwashing liquid and spray outside hose.

That's a complicated system that needs a qualified technician to service it. Lots of people can install them and they run fine, for a few years. Your indoor unit, operating on 2 heat elements, will feel like its blowing cold air even though its heating, just not so well. And not like you are accustomed to. Each element (5kw)=22.7amps, on average. So 3 elements operating should trip a breaker. Its probably been operating on 2 heat element plus the heat pump. And now you have trouble with the heat pump. If you can't TRUST the guys working on your equipment, try someone else. A second opinion. Normally a 3 or 4 ton unit will have 15kw heat installed, heatpump or not. 5 ton, 20kw. If yours is a 3-4ton, cooling, the 100amp(or normally two 60 amp) breaker should have been installed upon equipment change out. If yours is blowing cold all the time, something is wrong with your heatpump. The electric heat inside operates only when the heatpump can't keep up(real cold outside), the heatpump is in defrost(then it's actually in cooling mode), or if you have the tstat in aux/em. heat. Try a local trane dealer? Of a technician with 15-20 yrs under their belt. A trane dealer should have trane tech support also. BIG HELP!!!

I don't think the Amana ASZ14 Heat Pump has a reset switch, but you can still reset it by resetting the power (when it's not running... turn your thermostat OFF first).

To reset the power, locate your circuit breaker box. There should be a double-breaker for the Heat Pump and another double-breaker for the Air Handler. Turn them both off for at least 2-3 minutes. Then flip them back on and turn your thermostat back ON.

You're thermostat may also have a RESET button that you can push. I have to reset mine every time I change the batteries in it.

Yes. Heat pumps have to go into defrost just like a freezer when the temp gets too cold outside. The heat pump will temper the indoor air electric heat.

It sounds like your defrost board failed. You will need a tech to replace it. With that model it may have a parts warranty but you pay labor(?)

do you have a totaline t-stat. they and some other brands have a fan recirculation setting in the installers menu.

this is assuming that this happens in addition to the heating or cooling normally
