It sounds as if warm outside air is being drawn back into the room when the unit is not actively cooling. Portable units depend on room air to carry the heat outside, & therefore will not work properly if the room is too airtight. Provide a makeup air passage by leaving the door slightly open, & see if this helps. Use a room thermometer to see if your desired temperature is being reached. Note that if the wind is strong & coming from the wrong direction, it may not be possible to prevent warm air drawback.
Bear in mind that these coolers can also warm, depending on the orientation of the power cord connection. One end of the power cord has an arrow, the other end has a blue dot on one side and a red dot on the other. For cooling, connect power cord ends so that the arrow is on the same side as the blue dot. If the arrow is on the same site as the red dot, the cooler becomes a warming device, venting cold air outside the cooler and into the car. Could that be the problem?
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
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
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
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
It will likely blow much warmer when the outdoor temp rises.
Hi,I have had problems with my Blueway A/C it was very cheap but NASTY,anyway I might be able to help, I made a website with my manual that includes the error codes that I could not find on the net anywhere ,I have also sourced a company in sydney who has spares and have the contact details listed and started a forum that we can help each other out with
