Next, check the vents to make sure the system is balanced. In a mobile home, there is usually some metal tape, around the perimeter of the vent, to seal the floor around the vent, and prevent the air from blowing under the vinyl flooring. Vinyl flooring, is usually the only place you would find this, and a lot of manufacturers just glue the vinyl down around the vent itself. I have seen some home owners use aluminum foil to block off certain vents, when they were trying to get more air thru some, and less thru others.

Check that refrigerant first — if it is low, then the system has to work harder, to get the same amount of cooling. Most HVAC techs will tell you that the system should be cooling about 15 to 25 degrees from whatever the outside temp is, where the evaporator coil (the outside unit) is located. So — If it is 100 degrees outside, you should only expect a system that is in GOOD working order, to cool to about 80 degrees. If your system has less refrigerant than it is supposed to have, then it will just use that much more electricity, as it is working harder to circulate less refrigerant.

A good annual maintenance check is always in order… check your home every year for leaks around windows, doors, etc. Caulk where necessary. On mobile homes, this is a good time to spot check for the home being out of level, leaks, etc. Also look at the underbelly for any open holes that need to be sealed.
