How many btu furnace to heat a 3200 sq ft home in upstate NY?

A general rule of thumb in estimating the size of furnace needed to heat a home is to find the square footage of the home, and multiply that by 45 BTU (British Thermal Unit). For a 3200 square foot home a furnace somewhere in the range of 144,000 BTU would be a reasonable estimation of the furnace size needed to heat the home. To find the most efficient furnace for any given home, however, it would be best to contact an HVAC professional who can perform a load-calculation.

Why is my house air conditioner running but no air is coming out of vents?

Check your furnace fan. The air conditioner unit can be running but the air circulation is usually done with the fan on the furnace. If you have a fan switch on the thermostat, check to see if it is in the auto position. If it has the settings on/auto/off, you can switch it to the on position and see if you get any air movement then. If not, you could have a broken belt.
