    I like the Leatherman Surge. It has the replaceable saw/file and screwdrivers. The only downfall is the sheath, has thin strips of leather on the belt loop that will rip. So I've had to order a few...

    That looks like an Exhaust Fan. Most likely installed to ventilate the garage. It shouldn't have any noticeable noise or vibration. Most likely the belt is worn, or misaligned. I would think the...

    I wouldn't say that it is required, more of a just-in-case measure.

    I expect that the increased outdoor temp is causing the system to operate for longer periods of time, allowing the system to remove more humidity from the space. I would suspect that the system might...

    I use a shepherd's hook on the end of a length of tubing. Then either run the tubing to a drain or a 5 gallon bucket. Siphoning out the Aux pan may take a bit, but I prefer to not carry a full bucket...

    I'm a Liebert fan. If they have the floor space, install two Liebert DS 10ton systems w/ the iCom Controls. Then you can network them together to automatically Lead/Lag and rotate based on what ever...

    If you wanted them all to operate as one, I would just put a control relay on each unit.

    Making/Breaking power from R-W, then control each of those relays by a single controller.

    I would not operate this system until the proper repairs are done. Permanent damage could result from this mixing of refrigerant.

    Call a licensed service company to perform the repairs.

    I have always used a socket to aid in the bearing removal. I just use one slightly smaller than the shaft size.

    Sounds like the Aux Heat strips aren't coming on. I'd recommend you have a tech out to check it. It could just be something simple.

    From my experience, I find that systems need 1.3sqft of return air filter surface area per ton of cooling.

    So your 14x24= 336sq inches, there are 144sq inches in 1sqft, so 336/144= 2.333sqft

    It looks like the Condensate issue for the furnace is actualy due too the AC coil above it. The AC condensate is either leaking, or the Suction Line is poorly insulated. May just be a minor repair.
