Ruud Heat Pump blows room temp on Heat and AC setting

My Ruud heat pump started blowing room temp air the last couple of weeks of the cooler weather and we didn't pay it much mind seeing as the warm weather was right around the corner ("we'll deal with in the fall" mentality because the emergency heat worked fine). Well low and behold it hit 88 this wekend (and is supposed to continue for the next 3 days) and when we turned on the AC, surprise, room temp air. The fan cuts on outside and it seems as though the copmpressor does too and the system seems to respond to the temp settings (if you change it it cuts on correctly) but it's just blowing room temp air. We checked and it blows the same temp on either setting, heat or AC.

Another thing is when the heat started blowing at room temp on the normal setting (not emergency heat) the heat pump made an almost whining sound, not high pitched, just a little out of the norm. My question, as crazy as this might seem, is would the freon level effect the heat in some way? If I just need a charge then great, but if a charge doesn't effect the heat function, which I am pretty sure it does not, then I guess we'll be replacing the compressor. At least the downstairs system still works.

A "Heat-Pump" is also known as a reverse cycle air conditioner, this means on heat the outdoor unit acts like the indoor section and vice versa. So in all probability you need to have it leak checked and recharged.

Aux keeps coming on on regular heat is there something wrong with heat

See if it happens only when your temperature of the room is more than 3 degrees of your setpoint temperature. Since you have a heat pump, the auxiliary (electric heat strips) is use for backup of the heat pump when it can't keep up. The heat pump will run by itself if it can maintain temperature within a couple degrees. If it is too cold outside to handle the load or you set the temperature more than 2 degrees past room temperature, the auxiliary will turn on. The thermostat has a memory of how long it takes to reach desired temperature. If it goes into auxiliary mode trying to satisfy setpoint during the last call for heat, it will start the next call for heat in both aux & heat pump mode until the thermostats algorithm (timed program) allows only the heat pump to run. Not sure if you have an air to air, or geothermal heat pump. The outside air temperature will affect only the air to air system ie. when the temps drop outside, the heat coming out of your vents will be cooler...the air to air systems drops efficiency when the outdoor air drops.

Heat Pump - blows heat to set temp, then off, then kicks on to blow cold

Heat pumps defrost which is the AC mode, if the heat strip isnt working during a defrost, the air will be cold, A heat pump only feels warm if the heat strips are on too! the refrigeration cycles heat output is much less sensible to our 98F skin. heat pumps that satisfy a room setpoint are working at least, all heat pumps feel drafty to most.

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.

Heat pump stops working in cold weather

Sounds like there is a problem with your unit. The cooling tower doesn't have anything to do with the compressor other that the delivery of water to your heat pump. The compressor is probably shutting off on a low pressure because the water is cooler than in summer. I think the heat pump you have is low on charge or has a defunct TXV.

Ruud UBHC AC System - Provides no Aux Heat

Tried this on my unit today, and observed the same results, but got Aux Heat (with A setting), if the H (blue wire) connected to B terminal, as per instructions for my 6036 Ritetemp. However, in this case, when the set temp is reached, I hear the click, but HVAC still blows aux heat indefinitely.

I also have RUUD UBEA 17J10..., and replaced my old honeywell with 6036, and can't get heat pump working. Both of my units are 14 years old, so I'm thinking to replace them soon.

Ruud heating/ac unit blowing only cold air in heating mode

Do you have gas or electric heat. If you have gas then you do not have a heat pump. You should in most cases have a red,yellow, white, and green wires coming to the thermostat. R should go to rc/rh G should go to green Y should go to Y and w should go to W. Also the switches on back should be switched to non heat pump and gas rather than electric. Hope this helps.
