my home a/c lines freeze over and the system quits blowing cold. once they defrost then the system works fine until it freezes up again. any possible suggestions that i can check myself before calling a a/c repairman?

clean your coils for it , check your filter . odds are you will need to replace it
Reply:it is possible that your a/c system is low on freon, you'll have to call your local heating/cooling professional to look at it.
Reply:your a/c has moisture inthe system and could be under charged. just recieved my a/c certification.
Reply:You may have a bad defrost timer. Every so often an air conditioner defrosts itself. If that timer quits it will eventually freeze up.
Reply:YOU NEED FREON.
Reply:ok...first turn you unit off for about eight hours or so, this will give the lines time to defrost..then use unit again as usual....This happened to me before also....
Reply:bad evaporator coils or your system has a clogged line also look at the outside of the system and make sure you are getting proper air flow into the system itself.

Reply:outside of freon , sometimes if it is being used in high humidity, you will have to raise your home temperature. ( i.e. from 68 - 80 ) this stops the condensation from accumulating as fast on the cooling coils.


most of the time this moisture is only noticed as the water which drains from the back of a unit. with high humidity, it tends to have a chance to freeze before it can drain because of the amount of fluids pulled out of the air during the coolling process.


mine were brand new, worked fine, until a similar thing happened. we were going to chuck both, when the temp for cooling was raised, it stopped.


as least you might have a chance to amend this before you begin to spend extra money.


try it, you have nothing to loose, just make sure you can be comfortable with the new range. if not , it's not the right one for the purposes you need,
Reply:Change your furnace filters. Oftentimes the filters restrict air movement over the coil in your furnace.





Shut off the furnace, replace the filters, wait for everything to thaw out and start it up again.
Reply:If it uses freon then check to make sure that your freon is not low usually that is the cause of it, but if it doesnt use freon it usually means the blower is bad.
