THE WRONG SYSTEM SIZE COULD COST YOU
A system that is too large will cool or heat your house quickly, but you still may not feel comfortable. That's because it will satisfy the temperature setting on your thermostat before it can adequately remove sufficient moisture from the air—which is what makes you feel so sticky and uncomfortable in summer. What's more, the stress of short cycling (too many starts and stops) will shorten the life of your equipment and increase your heating and air conditioning bills.
A system that is too small just cannot get the job done. The air conditioner will run constantly in the summer and the furnace will do the same in winter, which may overtax your system and increase your energy consumption.
In most homes across the country, systems are in fact too large. And an oversized system not only makes it more difficult to control your comfort levels, it costs you money, because you're essentially paying to heat or cool space that isn't even there. That's why a properly completed load calculation is so important. Your independent Trane dealer can determine the correct system type and size for your home by doing a room-by-room load calculation.
