    Hi, can you give me some more information on this unit, is it a central a/c and heat system, gas heat or a heat pump, or a free standing heater? Model & serial # would also be helpful to solve this problem.

First check your filter, a dirty Air filter can cause you system too malfunction, after you have change the filter check with a thermometer in the return first record the temp and then find a supply vent and place thermometer in it and record the temp the difference should not be less than 13 degrees if so call a HVAC contractor you may have lost you refrigerant, or have a mechanical issue, i.e. compressor not working, condenser fan not working or dirty coils

Why does it just blow cool air?


Check outside condensing unit. Should feel warm to hot air blowing out of the top. If cool to outside air temperature blowing off you likely have a refrigerant problem

Gas heater short cycles


At your indoor unit, look at 1 of the front panels and see if there is a clear, plastic view port. Look through it and try to see a red flashing led. Count the flashes and look at the factory data on the front of the unit. That should give us a trouble code and lead us in the right direction. Also make sure air filters are clean.
