Thanks for the 1rst answer regarding central air. We have approximately 630 square feet of living space on each of 3 floors. the central unit is a Heil, 2.5 ton. there are 5 vents on 2nd floor (2 bedrooms and bath), as well as a return and thermstat (next to return). There are 4 vents in 2 large rooms on 1rst floor. Also 2 vents in basement. I was was told by another that we shouldnt try to cool basement so I just closed them.
After tracking the temp. 4 past 3 days we found that , if the thermstat. is set for 67, the 1rst floor temp goes up to 75-76. If thermstat. set for 70, 1rst floor goes 76-78 degrees. On the heatwave days the 1rst floor temp. reached 85 degrees.
The contractor said he will replace 2.5.unit with a 3 ton, but I'm worried that we will have same problem, and there is no room for more vents. Would putting in a Mitsubishi unit for the 1rst floor be better? Some one mentioned a damper; what is that exactly? Any recomendations? Thanks much.

don't get a unit no bigger than 3 ton, heat rises air conditioners are not meant to cool the basement cause a basement is always the coolest place in the house because heat rises. Get some one to make sure your ducts are sized properly. If you want both floors to be the exact same temp get a split system or 1 unit per floor. Dose your unit run steady. Are the freon levels good. Be fore you get a bigger unit make sure the filter is clean, all blinds are closed and try closing the vents on the first floor half way so more cool air is forced up stairs. the highest floor will be the hottest unless you have a damper controlled system since heat rises good luck! 2.5 ton should be big enough

Two things to check. Make sure the vents are fully open on the first floor. And check the ductwork to the first floor to make sure that there are no holes in the duct that could be leaking cold air into walls. Also check the outlet temperature of the vents going to the first floor.
Generally, the ground floor should be the coolest because of the insulation effect of the floors above. However, more window space on the bottom floor may allow more heat into the house.

If the living house is six years previous most of the time the guaranty is ten years on a compressor from the manufacture, and three much is gentle, extra like 3.5 much, round four hundred-500sf in accordance to ton. Get the style and serial and make contact with American commonplace they help you to understand of the guaranty! If less than assure the interest could be no more effective than 500-six hundred funds except you want to spend money! And to improve the air handler will double the cost of the interest. I choose I had shoppers like you who've no situation replacing the A/C equipment each six years. became this a similar organization who put in the A/C equipment contained in the first position. Why did the compressor fail, in case you do not locate the reason why the former compressor failed then the recent one will fail too, they could not flow undesirable for no reason. Is the compressor a burn out meaning a electric powered situation, did it lock up via lack of oil a piping situation or low on gas, or are the valves undesirable via eating liquid freon a unclean coil, or over charged. think ofyou've got a situation contained in the panel field, the disconnect field undesirable, freon leak, no not ordinary commence on a TXV equipment, piping issues? Many questions and no solutions. A properly put in equipment will very last for 15-25 years with out issues.

Sounds like you better find someone who can help you. Don't call "Uncle Billy Bob's heating and lawn care."
find yourself a company who is familiar with zone systems.
This is a comfort product that you depend on to keep you cool, don't buy it a the Salvation Army, if you want it to be right , you have to spend some money.

make sure your ducts in the heating system can first handle the air conditioning unit.... then hopefully your contractor will size the unit correctly and finally make sure your motor is big enough to push the cold air..
most systems are designed for heat.. not heat and ac...
good luck
