My unit does not go on. I press the on button and hear it then 10 sec pass hear it but it doesn't light and red light doesn't go on and then it shuts off

tep 1: Check the thermostat
  • Make sure that your thermostat is set to "cool" and not "heat" (if it's set to heat, your AC won't turn on no matter what).
  • urn the temperature setting 5 degrees below the current temperature to see if your AC will turn on.
  • No good? Then you need to...
tep 2: Check the air filter
  1. Find your return vent's filter (the return vent is where air gets sucked into the air conditioner).
  2. Check to see if the filter is dirty (if you can barely see light coming through it, it's too dirty).
  3. Change the filter if it's dirty.
    "Wait, why am I doing this?"
    A dirty air filter blocks air from returning to the AC, reducing airflow over the evaporator coil, causing it to ice up.
    This causes a low-pressure switch to trip and shut down your AC's compressor (the heart of your air conditioner) to prevent it from being damaged.
    So you need to change the air filter to prevent all that.

I own a Zenith Air Conditioner, model ZW651OR. It is only a month old and it is not blowing cool air any more. I live in Guam (relatively a hot climate) the size of my room is 10' X 12' and the air...

The problem could be dirty filters, dirty coil, refrigerant charge low,etc. Since it is only a month old I would try to return it if possible.

My a/c is blowing cold air, just not as hard as it used to. Don't know what to do. Don't what to waste money on a repair man if it something I,am just overlooking.

Besides your motor going out, somethings to check would be dirty/clogged air filters, dirty indoor coil, or dirty fan blades on the blower motor itself. The only other problem that would cause this would be a broken section of duct if you don't have slab ducts (concrete floor). Hope this helps!

18 year old Janitrol Heat Pump freezing up.

i would get someone to check your refrigerant levels have you ever had the evaporator coil flushed and cleaned? proper refrigerant levels and proper airflow across coils are extremley important not to scare you but 18 yrs is a long time on a heat pump 9-12 years is the point where they really loose there efficiency going for a newer one would probably cut your operating cost in half if not more depending where you live there are a lot of people not familiar with heat pumps so i suggest finding a company that specializes in them to service your unit

Central air conditioning system

Check the filter(s). Dirty filters is the primary cause for such failures. Secondly check the thermostat and make sure that it is not turned way too low. Anything above 70 is safe from causing freezing on the unit. If the unit is already frozen then turn the unit off until it is totally thawed and then retry.

The only possible explainations for your situation is that the air is either going around the filter and going straight to the coil or the air filter is on the wrong end of the furnace. The air should go through the filter before it goes through the furnace. If you can take the filter out and look at the coil, the air should be sucking into the furnace from that end, if it is blowing in your face, that is the problem. If all is ok with that then take a close look for where the air could be getting in without having to go through the air filter. Seal up any holes with duct tape or sheet metal or both.
