Air conditioner probably has a failed run capacitor inside the unit. Check all circuit breakers and/or fuses first.

SOURCE: air conditioner not blowing cold air

Just because the big one is cold and the small one is warm,Doesn't tell you if the system is properly charged or properly working.It is true that the big line will be cold and have condensation on it and the small one will be hot and dry,But this occurs in a wide pressure range,so the system could still be improperly charged.The charge in the system is based on the ambient temperature,The size of the system,The line footage,Etc............ So without a set of gauges and the ambient temperature,You can't really check anything but whether or not the unit comes on.

SOURCE: air conditioner

Turn off unit supply and check the blower wheel inside the indoor unit by rotating it manually by your finger if the blower wheel rotates freely then there is something wrong with your fan motor or fan motor capacitor. But if the blower wheel is not rotating freely try to check the fan motor for lubrication or some bushing dried of and no oil

My furnace works on ac and blows on ac but on heat it does not blow but i hear a humming sound coming from the furnace


Most furnace operating on Oil or gas will heat the combustion chamber before starting fan to prevent cold air draft at start-up, can last a minute or two. Eiter the main flame does not come on or the chamber thermostat have fail. Try to modify fan option on room thermostat from auto to on. Cold air coming out: burner problem or no more oil or gas, warm air: burning chamber thermostat problem, leave room thermostat fan option to on until repair.

Goodman central air conditioning. Little air is coming from the vents in the house and the air that is coming out isnt very cold


have the central unit blower/fan cleaned as they block up from dust and other particles so that they eventually look like logs and do not move air like they should. Have the unit gas pressure tested for correct amount of gas

mcdevito75 here, The compressor may be running but without the fan, no air will come out of the vents, Double check the fan operation on your A/C unit, turn the fan speed switch see if the fan is working if not, see your local A/C repair shop.

To check for bad thermostat, take off the front cover to reveal the 4-wire terminial and jump the red-wire (power)-cool,(yellow -y or blue)--- green--fan white-(heat)..........red to yellow-or y=cool. Thank-you-very-much!

No air flow upstairs


Cold air is denser than hot air, so is harder to move. All vents have some mechanism to regulate flow, so close all of the downstairs vents. Check to see if your furnace fan motor has more than one speed, & set it on maximum. Keeping the fan on all the time will help as well. If all else fails, you may need a more powerful fan motor.
