There is a tool called a Air Flow CFM Meter. It's measures the amount of cubic feet per minute moved. I don't think it would be wise to buy one for a DYI checkup. For the cold air returns, the one that pulls really strong is more than likely the closest to the furnace. The other two barely doing anything.. do they happen to be on the second floor? or far away from the furnace?
There is also the possibility of them being disconnected or very leaky ( which is quite common ). Having a mini windstorm under the drywall in your basement however, is not. This tells me you more than likely have had a pipe disconnect under there. Your options here.. take down the basement ceiling. And while your at it.. seal all of the exposed ductwork (now that you can see it) with Metal Tape. Re-finish the ceiling. You should also consider having the Air Ducts done while the ducts are exposed. You'll get a more through cleaning However, that really depends on who you hire. Problem Solved?
If the green beast is still running.. let 'er go. Cause yer broke. If it's currently broken, I would replace it with a new unit. That's if you want A/C for the rest of the summer. You will definitely save money with a new unit over the green beast. A DC fan motor would also save alot in regards to operating costs.gwan wrote: ↑Jul 25th, 2011 5:13 pmmy air conditioning/CA unit is 1983 and it's one of those big green square unit..
right now i have no monies to replace it but do you think it's worth borrowing $2400 to install a new one or just wait until next year?
am i going to save a substantial amount of money every month by getting a new high efficiency CA unit?
The ECO energy program is back too! til March 31st 2012. You can get government rebates of up to $250.00 upon the purchase of a new A/C. You also can get up to $400.00 from the Ontario power authority for putting that A/C in. Not to mention the countless other rebates available for other areas of the home. It's definitely worth looking to.
