Ask if the service tech is getting commision on the parts you are buying and if the price can be reduced. Not all companies do it but ask when you call. Another rule of thumb to estimate tonnage needed is 1 cfm (cubic feet per min) of air per square foot and 400 cfm per ton of AC -so 1200 sq ft house needs about 3 tons of air. Of course the tighter and more insulated the house the lower the tonnage. Over sizeing the unit can be worse than too small. If the unit short cycles because its too large then the humidity is not removed and the house would be cool but clammy. Hi SEER rated units are only as good as the house they are installed in. You can put chrome rims on a Pinto but its still and old rusted car. Pay the extra money on insulation if your budget is tight-the unit will pay back sooner.
