Why would my combo A/C - Heater unit not blow air while heating or cooling is selected but will blow air just fine when set to "fan only"?

Sounds like wiring issue to me. I've delt with units like this and there is a wire lead for fan only and a separate one to run the fan when the unit is cooling or heating. I'm only speculating here but I would bet money that this was improperly installed.

Dont get discouraged though because it sounds like its working (for the most part) if you feel up to the task find the manual and check your connections. Otherwise hire a professional.

A Great Tip For Saving Money

While everyone usually remembers to change their AC and Heater filters, no one thinks about cleaning the heating or cooling outdoor coil. If you have an outdoor unit for heating or cooling, those coils need to be clean too!!

The principle of an HVAC unit is to remove heat or cold from your home to make sure you have a comfortable temperature inside.

If you have a gas furnace, your good to go in the winter. Make sure you change your filter every month and you should be able to keep your home at an nice temperature for you and your family. BUT, if you have an air conditioning unit hooked up to cool your house in the spring and summer, you need to do a little maintenance every spring to make sure you get the most out of your unit and save money. The same principle works for a heat pump, so i'll break it down for each unit.

1. An air conditioning unit that has a gas heater works just like it sounds. In the winter, your thermostat will tell the heater to turn on. You will have your burner running until the fan switch in the heat exchanger gets to the right temperature to turn the fan on. This is so you don't have cold air circulating through the house. Cooling on the other hand works a little different. If your thermostat calls for cooling, your fan will turn on right away and your condensing unit outside will turn on. What you AC is doing is removing heat inside the house and putting it somewhere else. That;s where your condensing unit comes in. The heat you removed inside the house is transferred outside where it is compressed and cooled through the use of the outdoor fan.

Now, imagine if this outdoor unit has dirty coil. You are no longer able to remove the heat from the house because it's not able to be removed because of a dirty coil. This means a huge loss in cooling capacity, higher running amperage on the compressor, and your electric bill being alot larger than it needs to be. I'll have the solution after I address the heat pump.

2. Now, the heat pump. It is basically an air conditioning unit that can reverse. In the summer, the outdoor unit will blow hot because of the heat it removed in the house. In the winter, the outdoor unit will be blowing cold because it is using the heat outdoors to add heat into your house. While this sounds weird, it's engineering at it's best. In the winter, heat is able to be removed from very low temperatures and your able to transfer heat into the house because you have a compressor in your unit. It does what it says. It takes a low pressure-low temperature refrigerant and compresses it into a high pressure-high temperature refrigerant.

Now, getting to the coils of both units. You need to clean the outdoor coil on both units every spring to make sure you have a clean coil. In the long run, this will allow the unit to expell the heat gained from the house and in the long run will add life to your compressor and save you money.

On the heat pump, you'll also need to clean the coil every fall. This is because if you don't, you could have a problem with freezing your outdoor coil. If you can't remove the heat from indoors, you will slowly turn your outdoor coil into an icemaker!!

So, based on what you have, turn the power off to your outdoor unit. Spray very good with a degreaser such as simple green and let it sit for about a half an hour. Then, grab your hose and wash out the coil. You'll be amazed what comes out. Let it sit for a coup0le hours to dry out, then turn the unit on.

This will not only extend the life of your compressor, it will also save you money in the long run!!

Have Goldstar Model R1804h ac/heater window unit when turned to heat blows only cold air what is easiest thing to check and purchase first.

If your thermostat is working on the Heat cycle (listen for "click" when turned up and down on Heat), then your heating coil assembly is probably bad. The heating coil is in series with a Fusible Link and a Bi-metal thermostat, if any of these three fails, there will be no heat from the coils.The Link and Bi-metal Thermostat are made up as part of the heater coil assembly.

Fan blows but no heat. Green light flashes four times

If the fan blows and green light flashes. When the green light is fix, it means the time is set to start your heat pump. Check your electrical control and wiring for any damages including the terminal lugs, capacitor, or relay. Check also if the thermostat is working. If your heating comes from heating coils, check continuity of the heater wire including the overload. Replace any defective parts.

Unless we set the thermostat very high, like 80 degrees, the heater will blow cold air. When the heat does blow, it will eventually stop blowing heat and the fan will continue to blow cold air.

Check and make sure the filter is clean. This sounds like a restriction in the system. If the unit has central cooling make sure ther indoor evaporator coil is clean at the furance.The unit may be cycling the burners on and off at the high heat limit , fan/limit control. You can also eliminate the thermostst from the furance. Turn power off at the furnace and disconnect the wiring from the thermostat. Jumper the red and white wire together. Turn the furnace back on. The furance should run in the heating mode. Try this and see if the problem is still there.

How do I Turn the heat on ?

It's hard to answer that question because there are so many variables. First I would look at the thermostat and see what manual settings are available. If it's a non programable there should be a switch that goes from heat to cool,one position for fan on , one for off, and one for auto. Set the heat/cool switch to heat. the fan on ,off and auto to auto. Then turn thermostat control up so it's above surrounding temperature.This should cause the heater to come on. If that doesn't work you may have problems with heater or thermostat. If it a programable t-stat I will need more information,such as name brand,model,etc. Hope this helps. Thanks.

Lg window-type ac

Most little window units are mainly for 300-500 Square foot rooms.
Should be putting around 80-105 degrees top out of those little units, Make sure that your thermostat is set for heat rather then the normal setting of cooling (Turn more towards Heat) also if you have a fan setting you may want to try lowering the fan to low speed vs high fan, which should give you more heat.
Make sure the Filter is clean as well as the coils behind the filter or it will shut down the heaters quicker due to lack of air, shutting down your T-stat and bi-metals quicker.

Good luck!

Heater smell when AC comes on...

The fan that blows the air blows through the heater coils before it blows through the A/C.As long as the heater doesn't come on, there is not much that can be done. ZCooking the attic room will be a problem because it is the heat rises thing, and on top(literally) of it all, the roof is radiating heat.

Heating not working like it should

The fan for the A/C should blow harder than in heat. The fan should be on high for cool and low for heat. You can change the heat setting for medium but I would not recommend it because it may make heat coming out feel less.
