Having problems with your Air Conditioners ?

Is there a second air filter inside a central ac unit ? I change my filter on the air intake faithfully. Always using high grade quility filters. it was brought to my attention that there is another filter internaly that also needs changed ! Is this correct. I have a Thermal zone model# AH24A-1T it is about 8 years old.


Answers :

If you have only 1 trunkline for the return and you have a filter grille with a filter in it, it is not necessary that another filter be installed in the air handler. But if you have more than one return or if you have a fresh air intake tied into your return, the other filter might be necessary. Too many filters can actually create problems with airflow do to excessive resistance. All this said, it is best check to see if your return has branches coming off of it or if it is only connected at the filter grille. If it is only connected at the filter grille, you should be able to remove the internal filter unless, of course, that filter is doing something other than just filtering the air entering your air handler.

I have noticed in the past 24 hours that my air conditioning has not been as cool as it normally is. I changed the air filter in my furnace and my air is still not getting any cooler. I checked the ignition light and it is green and flashing. I know it needs to be green but not sure about the flashing. I can also hear my furnace running. What can I do to get some cooler air flowing in my air conditioner?

Where can I find a manual for my coleman cam II central air conditioner for a mobile home? I recently purchased the mobile home and would like to know what steps to ntake to make it work at its best. Also, I find it puzzling that the air filter is set on top of the unit inside the mobile home. It looks to my limited knowledge of central air, as if someone set the filter on top of the unit because they did'nt know the correct location placement. Can you provide any comments or advice? Thanks

I have a Haier HWR10XC6 and it's only two years old. It has been shooting out hot air. I removed the sleeve to the airconditoner since i read online that it may need to be recharged. Can this be correct and also where would i place the refrigerant at? Where are the valves located at??


Most all window units (if not all) are 'sealed' units and have no valves. The reason being - is that they rarely need charging - unless damaged somehow, i.e. dropped, or one of the coils is punctured somehow.\015\012\015\012AC's sitting ... Haier hwr10xc6 Air Conditioner

Our Carrier Furnace will sometimes work fine, however, at times, it will just not go on. Our thermosat is set to 68 and many times it will drop to 65 or even 63 without turning on. It happens every so often and we usually just flip the switch on the side of the furnace and it will ignite and start right up. We have changed the air filter. Is there something else that needs to be done, so that we can always get it to ignite?

On Sunday evening we turn our heat on and then on Monday we turned the air conditioning back on and it won't turn back on. We shut it down for a couple of hours and while it was down we cleaned it and changed the filter. We are now thinking maybe we need to add some freon but we don't know what kind to put in. Do you think we are headed down the right track or are we missing something more obvious?


There are quite a few things too check before you just add freon\015\012 first check to ensure you have voltage at the condensor, when you select it at the t-stat.\015\012 Make sure you have the t-sat set below ambient temp\015\012 ... Intertherm Air Conditioners
