Put new batteries in the thermostat. Make sure that the switch that power the furnace is in the "on" position. Sometimes people mistake that switch for a light switch and turn it off.

Air Conditioners Cooling Tips

  • Whole-house fans help cool your home by pulling cool air through the house and exhausting warm air through the attic.
  • Set your thermostat as high as comfortably possible in the summer. The smaller the difference between the indoor and outdoor temperatures, the lower your overall cooling bill will be.
  • Avoid setting your thermostat at a colder setting than normal when you turn on your air conditioner. It will not cool your home any faster and could result in excessive cooling and, therefore, unnecessary expense.
  • Consider using an interior fan in conjunction with your window air conditioner to spread the cooled air more effectively through your home without greatly increasing your power use.
  • Avoid placing lamps or TV sets near your air-conditioning thermostat. The thermostat senses heat from these appliances, which can cause the air conditioner to run longer than necessary.
  • Plant trees or shrubs to shade air conditioning units but not to block the airflow. Place your room air conditioner on the north side of the house. A unit operating in the shade uses as much as 10% less electricity than the same one operating in the sun.

    The display went blank on my honeywell t8600c thermostat. when the batteries were changed, the display shows the time and -AC. Nothing else functions

    I believe this thermostat will display -ac if it loses power from the furnace or air handler. Your thermostat will operate on low voltage(same as your door bell) and constantly powers your thermostat. I would check your furnace breaker, and fuses to see if there is power to the equipment

    Symbols on fridge freezer- i have a flashing symbol that looks like a test tube with a rounded end on hotpoint fridge freezer- what does it mean?

    Is the water draining from the unit? It sounds to me like that symbol is telling you the water that has accumulated from removing the moisture in the conditioned air is full and needs to be drained.

    What symbol is for air conditioning?

    Here is the operating manual
    On Page EN 7 it has the operating instructions for the hand held remote unit. When the word "cool" appears in the display, depending on the temperature that the room is and what the remote is set for, the unit will function in the air conditioning mode.

    Ruud air condition

    You must be kidding. You want a video?

    If the filter is in the air handler, it is in the bottom. Often filters are not in the units themselves, but in the main return grill in the ceiling. But if it is in the unit then:

    Turn the unit off at the thermostat. (That way the fan is not sucking the filter up,) Then take the bottom door off. It is a small door and a pain, but you can do it. Pull out the filter. It is a washable black plastic framed thing. Then wash it and put it back in. Then make sure to put the door back on and turn the thermostat back on.

    Heat pump works in emergency heat, but not in auxiliary heat

    I set the thermostat for 70 degrees. It comes on always in auxillary heat and does not shut off when it reaches 70 degrees. It is a heat pump, I am assuming, it might be the thermostat? But when the air conditioner is on, it turns off when it reaches it's temperature.
