Could be a few things. Is the outdoor unit running? If not, it could be an electrical problem is sensors, control board, wiring, maybe the settings are nor right on the remote. If the outdoor is running and its still not blowing hot or cold, it may have a gas leak.. I have made these assumptions that it is aKelvinator split system? 1 easy attempt that you can try is a full system reset. Turn off the machine at its isolator (usually next to the outdoor unit) or at the Meyer box. Leave off for at least15 mins. Turn back on and see if it works. Good luck

Unit alternates cold, warm, cold, warm etc..


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.

2000 NISSAN 4X4 P/U A/C SYSTEM WILL BLOW COLD WHEN OUTSIDE AIR TEMP IS COOL, WHEN HOT OUTSIDE AIR BLOWS HOT.


your auxillary fan is not working. this fan is responsible for cooling the freon that is being circulated in your cooling system... check if there are any loose wires in front of the engine bay.

the auxillary fan is located right beside your radiator fan.

2003 toyota celica vvtli 190bhp heater blowing col dair only and engine over heating. no signs of leaks oil clean, coolant resivour just above min any ideas whats broken cheers


If it is blowing cold air, that means the coolant level is low, the heater core has no coolant in it. Sounds like a head gasket is leaking.

My 2003 Denali blows cold air in the front but the rear only gets room temp air. It doesnt get cold or hot just regular outside air . Please help. Is there a sensor or relay that needs to be replaced?


There is a blend door that blends the hot air from the heater core and the cold air from the A/C evaporator to make the air dry and just the perfect temperature. I am going to bet its the blend door. the Rear trim will need to be taken off and then you can see what is going on. I don't have any pic of the box but its not that complicated.

REPLACED BOTH ELEMENTS GOT HOT WATER FOR 1 SHOW THEN IT GOT COOLER AND COOLER AND NOW ITS COLD ONLY?


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 did not specify...if this is a heat pump, make sure you have 24 vac on the O, orange wire at the unit from the stat ...(0vac on Rheem, Ruud). If you do, you may have a bad coil on the reversing valve or a stuck reversing valve, or very low on refrigerant.

Check your outside unit to see if fan is running. If it is running check to see if air is blowing out if not you have a bad capacitor. Some times if a capacitor shorts out the fan will run backwards and the line will get very hot same as if the fan is not running. Russ
