Yikes, it's alarming that it's 92 degrees in the house. My AC unit is set to 65 degrees and it blows hot air; right now my house is about 80, I think. I'm not sure what causes units to do that, so I'm going to call an air conditioning service to see if they can make it work properly. You should probably do the same before it gets any hotter in your house.http://www.rivervalleyac.com/Yikes, it's alarming that it's 92 degrees in the house.

You have a slow leak in your refrigerant and need to find the leak. you will have to get an AC repairman to come to your house and check it for leaks and fix the problem.

Chances are your portable unit is a reverse cycle unit...If so, the leaving air temp in heating mode is not usually much warmer than room temp with 85 degrees F just about the maximum under PERFECT design conditions. A small portable in a large cold room may only be discharging 75 degree air, which is going to feel cold.
If your unit is NOT a reverse cycle unit, the heating source (probably electric resistance) is either not coming on at all or a portion of it is not coming on due to a defective element, burnt wire or a control issue.
in high temps AC units undergo whats called thermal inversion. This is when it blows hot inside and cold outside. I do not believe there is a fix for this. Maybe it is not properly sized for you room? If your unit is too small, it may be working too hard and inverting.
firstly is the air comming from the outdoor unit cold or warm? if it is cold then the 3way valve is working and it has changed to heating. If it stays warm then it is still in cooling mode. The indoor fan wont come on until the coil temp gets warm enough, ( so it doesnt blow cold air on you straight up). If it is changing into heat mode then the larger of the pipes connected to the outdoor unit should get warm/ hot. If this is not happening then the unit is either out of gas or the compressor is on hollidays and wont come back to work.
Find a reputable HVAC contractor to do a
room by room analysis with heat and cooling loads calculated and units
sized and duct requirements and compare to what you have.
The air not being cold is not necessarily an indicator of anything
malfunctioning. High efficiency units for instance don't produce cold
air.
Since you have had someone look at it, the duct
work may be collapsed which restricts air flow or uninsulated which
warms up the supply air. Either one is a possibility. Any Cox Cable guys
been stompin' around your attic lately? Wouldn't be the first time.
Usually, when the air coming out of the vents is not cold enuf it's because your freon level is low. Probably leaking, but they can usually recharge the freon and it will work for a while. Try another repair company and see if they can recheck the freon level.
We have a high efficiency unit and it produces cold air, so I don't know what previous poster is referring to. Air conditioners are supposed to blow cold air.
Sorry, to tell ya but it is normal if the outdoor temperatures are much
below 45 degrees. Below 45 degrees there is little heat outdoors for the
heat pump to grab to heat the home so it will run 24/7 and blow cool or
cold air. Below 45 the temp of the air coming out the vent will decline
and you will get no heat from the heat pump itself as you near
freezing.
Your emergency heat or auxiliary heat is electric strip heat. But it
only kicks in during normal operation if the temp in the house drops 3
degrees below the setting. (some tstats if can be 5 deg.) Otherwise the
heat pump will blow cool or cold air the rest of the time if it is too
cold out.
To prevent it from running all the time and blowing cold it is
recommended if the temp outside is falling below 45 degrees you should
just switch to the emergency heat setting, which shuts the pump outdoors
off, and just heat with the electric.
But if there is no heat outside the heat pumps will blow cold. They are
the cheapest and most efficient forms of heat but only as long as the
outdoor temp is above that 45 deg..
I'm guessing that if you haven't experienced this you live in some place
with moderate winter temperatures like in Northern Florida and rarely
get very cold winter temps like the freezing you have seen there
recently.
It will likely blow much warmer when the outdoor temp rises.
you may have a dirty condensor coil its the coil near where the warm air blows out or maybe a dirty evaporator coil its where the air gets sucked in check both of them and then see whats the air temp going into the evaporator and the temp. coming out of the vents that blow cold air the diffrence should be about 15 - 20 deg f let me know what the temps are ...but first clean the filter and both coils
check outside unit large pipe should be cool or even very cold small pipe should be warm to touch that will eliminate some questions in order to solve problem also check circuit breaker for outdoor unit see if fan on outdooor unit is running and listen for compressor hum
Do you have a heat pump? If so this is normal. You are probably used to a gas furnace. There are heat pumps that do have a delay though. Look on the circuit board in the air handler. There may be a set of pins that say 0-30-60-90 yours may be at 0. Also some digital T-stats offer that function for delay off to get the extra heat or cold from the system. Find out what the model number of the air handler and call the Goodman supplier in your area to see if you have these options. If you have a gas furnace and it's not delaying the blower there is definately something wrong.
