If your Heatpump's fan isn't running but your compressor is, your fan motor is out. If nothings happening at all ensure your getting power to heatpump (ex: breaker tripped, fuses blown on outside power switch, or fuses blown in breaker box?)

Unit not working correctly. The unit worked for the winter, few days ago I turn on the AC and noticed that it wasn't cooling like it should.


It's could be the board or a heat relay. See if you have 24 volts on "x2" im assuming, emergency heat when in cool mode if so it's the board. Or unhook black or x2 or your emergency heat from board and run unit in cool. If heat stays on its a relay

Yes, I believe you are correct concerning the circuit panel.

Regarding your heat pump not keeping up ...depending on what part of the country you live in, heat pumps are not the best thing to heat with. As you probably already know, once it reaches 32 degrees outside, the heat pump stops working and the electric furnace or heat strips come on to supply warm air. Frankly, when that happens, it's like turning on your kitchen toaster and blowing air across it with an electric fan. Doesn't sound to efficient does it. Plus, your electric meter is spinning like crazy and the power company is falling in love with you.

In my area (Virginia) most new home construction is now using what's called a dual fuel system. It's a heat pump, but it has a gas furnace backup for when it reaches 35 degrees outdoors. It's very, very efficient and a very comfortable heat. The gas furnace can run on either Natural Gas or Propane Gas.
In most cases this can be added to an existing heat pump system. The only thing necessary is the Gas Furnace, since you already have a heat pump and all the duct work. Could probably be added for a whole lot less than you''d expect.

The other option is to add a vent-free gas fireplace or vent-free gas logs, if you have an existing solid fuel burning fireplace. They are great for zone heating and/or supplemental heating. Plus, if you have a power outage in the middle of the winter, they'll still work, as they don't require any electricity.

I didn't mean to run own, but I hope all this helps you solve your heating problem.
Please let me know.

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.

Carrier 38CKC042300. oUTSIDE UNIT FAN WAS TURNING REAL SLOW. ac UNIT IS OFF BUT FAN TO OUTSIDE UNIT IS STILL TURNING. sHOULD NOT BE TURNING AT ALL WITH AC UNIT OFF


The outside fan may run if the unit is in defrost mode this is normal for most heat pumps it is there way of trying to keep the outside unit from staying iced over so the next time the unit runs it will have air flow through the coil and the ice will not be there to prevent air flow.

Frigidair HVAC not cooling; Believe its a emergency heat problem


the switch is on your thermostat - look for something that says "system" or "Em heat, heat, off, cool" switch it to "cool" and enjoy. If that doesn't work, call a HVAC service tech. You could have bigger problems than just the system switch. Good luck

Ruud Heat Pump blows room temp on Heat and AC setting


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.

It sounds like the coils are fine if you are getting heat. They are likely shutting down from overheating after being on for awhile. Check your filter and overall air flow to make sure it's adequate.

Ruud heat pump question


Does the air handler take a minute or two to start, this would be normal so that it doesn't blow cool air into the house before the unit is warmed up. If not could be the fan relay is weak and needs replacing. As far as the outside unit it sounds like you need to check the refrigerant. In cooling they are 70/150 psi. This should be checked in cooling mode, once you turn it to heating mode the pressures switch bring heat inside the house instead of out. I hope this helps.
