Heat load calculations need to be conducted for home to determine the proper size furnace. There is no simple answer to this question. There are a number of factors that can effect what size your furnace should be. Example: square footage, duct work size, insulation factors, windows etc. I recommend having a heating professional look at your home and conduct a heat load calculation. Over sized and under sized furnaces can cause you number out problems in the long run.
You take the size of your home in square feet and times it by how many rooms you have. A 70,000 BTU furnace will heat a house 1600 square feet.
I would say a 40,000 BTU furnace could big enough to heat a 400 SQ ft house, but where have you found a 400 SQ Ft house?
75000 acres
how big of a gas furnace do I need for a 2 story 2300 square foot house in northwest ohio
75,000 acres is 117.19 square miles.
it was very big, very big
The evaporator may be dirty or the condenser(outside unit) may be dirty. You may be low on "freon", indicates a possible leak. Check the filter. ---------------------------------------------------------------------------------------------------- If you're asking why the 'outdoor' part freezes, it's too cool outdoors. You should never run a house central A/C when the outdoor temperature is below 60 degrees F. Professionals will tell you that you can blow out a compressor this way. Big $$$$. You may be asking why there's a part in your furnace (that has part of the central A/C inside) that freezes over with ice in the summer. Your first clue will be that the house gradually grows very warm even though the A/C is running, and it worked fine until now. If the indoor air is too hot and damp when you turn on the A/C, you can overwhelm the system's ability to move heat out of your home. Instead of collecting moisture at the heat exchanger inside your furnace and using gravity or a small pump to move the water to a drain or outdoors, the water freezes right on the heat exchanger. The ice acts as an insulator, continues to build and the house will remain warm. This can cause expensive damage as the ice grows too big for the area around it. Switch the thermostat to heat (furnace) instead of cool and raise the temperature setting for about 5 minutes and the ice should all melt, then you can switch back to cooling. Since you've already removed much of the moisture in the house, you'll probably be fine, and the few minutes the furnace was running won't even be noticed.

A heat pump is a central air conditioner that uses a reversing switch to operate in reverse; the way the air conditioner works in the summer. If you went to the big fan unit (condenser) outside your house during the summer, you would notice, it blows hot air from the fan . Heat pumps are used to produce heat for residential housing, economically, by absorbing temperate winter air, and using it to heat your house. Heat pumps can usually maintain heat in your house down to about 20 degrees Fahrenheit, until you would need to use another source to heat your house. Heat pumps are mostly used in the Southern parts of the United States, where the winters are mild, Heat pumps can be economically used in other parts of the United States where average temperature during the winter may not go below the 20 degrees, disused earlier, and the break-over price for fuel cost using the main furnace. Usually, propane gas, verses running the electricity for the heat pump is more economical. To find out if a heat pump would work for your situation. Contact a qualified hvac contractor to perform an energy survey of your residence.
