your central unit outside condenser motor is gonna someday die, thats a fact of life, will you pay some guy 450 dollars to replace a 75 dollar part? or will you go for broke and fix that puppy yourself? one thing to keep in mind is the blade being attached to the worn out motor aint gonna wanna depart from its dead buddy too easy. ok maybe you got 50 bucks to go buy another blade and dont give a dang ,but if you take your time and do it right, you can remove the old blade and save some suds money .put the old motor and blade into a vise, get some sand cloth and start smoothing up the motor shaft surface between the blade and the motor get it as clean as you can ,then take a piece of hollow pipe about 6 inches long and place it on the hub being carefull not to hit the shaft ,you never want to hit the shaft, as it will expand and not allow the hub to come free ,DONT BEAT ON IT! tap down on the hub of the blade,with the hollow pipe,into the cleaned portion of the motor shaft ,and then, sand smooth the portion of the upper shaft you have exposed. add some good penetrating oil and wiggle the sucker off .Take your time and you will save money

and to add to that one of the most valuable features on your heating system cost about $0.50  . what could it be you ask ? the air filter, i have found the standard blue filter really works better then the more expensive ones for this fact it allow better air flow then the micro filters altho the micro filters say they last up to 3 months it can become blocked in the first two weeks and drasticly reduce the air flow to the blower motor making it work twice as hard with even less results thus causing the motor to burnout sooner and when the blower moter goes then you can develop other problems with other parts of the heating and /or cooling system  , and if you have a/c some dont but the same rule applies but moreso for those who have a/c never run the system without the air filter because now the cooling coil inside will begin to act as the filter and once it gets blocked/pluged it will cost a small fortune to have this problem corrected , spend a little and save alot,

I Like the cheap blue filter also mostly because of what I charge to clean the evap coil after a year of them.

Hi,

Help me out on this. Are you referring to the system air filter that filters the return air to the blower(heating and cooling if applicable)? The one where I live is 14x24x1; a 3M is presently installed.

Mine is ready for change; how do I identify a "standard blue filter"? Brand? Source? Home Depot, Lowe's, OSH, Walmart, Target?

Sounds good to me.

TIA.

Cheers!

Jim

The Force dictates that I must tell you, that if you are using a 3m pleated filter that is the correct size, you should stick with what you're using.
