For that 1 ton you will need appx 400 cfm total for it to operate properly. If you have 4 registers, that`s 100 apiece. If you have less registers each one will deliver more cfm, more registers less cfm per register.

If you left laptop plugged into the main all the time would it affect the battery in any way?
i think you mean that let the laptop work with laptop adapter and the battery. well, i suggest that you should work with the laptop adapter for the most time, cause when the laptop battery is full charged, the adapter won't stop it's wrok and keep charging the battery, that means the battery has to discharge(supply the power) and be charged at the same time. unfortunately, this condition may decrease the life of most lithium basic batteries. so, keep the laptop working with the adapter for the most long time.

Why is my mouse unresponsive at times?
This sounds like a problem with the mouse. More than likely, there is a problem either with the cable and/or with the logic board in the mouse itself.
If you have tried replacing the mouse, then check the USB port that you are using to see whether it is damaged. The easiest way to do this is just to plug a known-good mouse into the current USB port and see what happens and then plug it into another port that seems to work fine (such as one currently used by another device, maybe a printer) and see if that works.
If this is a wireless mouse and what you meant by unplugging and replugging the mouse was the wireless receiver for the mouse, then you should try relocating the receiver (often referred to as a dongle) to someplace else that has better reception. For example, frequently people will put the dongles on the backs of their desktop computers because they are long and "ugly" but with all the cables and especially the power supply being back there, interference quite often is present and the mouse works poorly. You can also try getting a USB extension cable and relocate the dongle to someplace more free of obstructions or other interference. As a great example, I have my wireless dongle located out of the way at the top of my hutch at the end of a 3-foot extension cable. That allows both my wireless keyboard and trackball to work without any problem whatsoever.
Also, just to play it safe, if this is a wireless mouse with which you are having problems, remove the battery and test it with a volt meter. A brand new AA or AAA battery will typically read at 1.65V while a battery that is completely "dead" will read at 1.2V. (A battery is no longer viable once its voltage reaches 80 percent of its nominal voltage. In the case of AA, AAA, C, or D batteries, that nominal voltage is 1.5, so dead is 1.2V.) I have had various clients change out batteries in their devices with no improvement in use, only to find when replacing the batteries that they were using equally dead cells instead of something newer. (In one particular case, the gentleman replaced a battery reading at 0.8V with one that read 0.05V.)
For recommendations regarding equipment, I have found that the cheaper brands and "no-name" brands tend to have many more problems than the known companies. Out of the most well known names, I find that Logitech is the most reliable and robust in any environment in which I have installed their products for clients. You might consider a Logitech device the next time you replace whatever you are using now.
I hope all this helps. If you have any other questions, feel free to drop me a line. If you are in the northeast Kansas area and would like professional assistance, let me know and I will schedule an appointment with you through my company.
Can a motherboard fail due to liquid damage if the spill was over 3 months ago?
Speaking as a professional who has seen spills on laptops and desktops from clients over the course of my career, I would say that the likelihood is minimal. If the liquid were corrosive, then there is a chance that the residue from the dried liquid would have continued to cause damage over time but that is not common in household or most office settings. Most likely, the failure you have experienced so longer after the liquid spillage is related to another root cause such as a power spike, failure of a capacitor, etc. If you want to determine what has failed and potentially get a reason for its failure, take the bad hardware to a professional computer repair shop and have them inspect it. If you are in the northeast Kansas area, feel free to drop me a line and I will be glad to accomplish this for you at no charge,
