While many people know that they need an air conditioning system to cool their home or business, finding the right size unit can be a difficult and time consuming endeavor. It can also be a costly mistake since the wrong unit will use more energy than one which is correctly sized for the area. A mis-sized unit will also have to work harder, be repaired more frequently and replaced sooner than a unit of the appropriate size.

Many people incorrectly assume that the bigger the air conditioner, the better it will be at cooling the desired area. Unfortunately, this is far from being true. This misconception came into play around the 1980’s when air conditioning systems were big and used a lot of energy in order to cool a selected area. This was a time when electricity was cheap and insulation was minimal at its best and nonexistent at its worst. Things have changed since then and now energy efficiency is the name of the game. Modern central air units run in cycles, working slowly, but steadily in order to lower the temperature of your home or office. If you’re wondering whether or not your unit is too large or too small, here are a few points to consider:

Your HVAC system is too big if you find your unit going through quick and short cooling cycles. This happens when the unit quickly cools the house and then shuts off, without utilizing cycles to cool the area. While the house will cool quickly, heat will soon infiltrate the space and the air conditioner will have to click on again. This constant on-off cycle will cancel out any attempts at energy efficiency and will add substantial costs to your electric bill.

Your HVAC system is too small if it constantly runs and you find yourself spending most of the day waiting for it to catch up to where it should be. The house should still be nice and cool (unless the unit is drastically too small), but the air conditioning unit will be overworked and your energy bills will continue to climb.

Again, it cannot be overstated how an oversized or undersized unit will have to be repaired more often and replaced quicker than a unit that is the correct sized for your living area.

Your HVAC system is the right size if it runs through the number of cycles necessary to cool your home, without running so frequently that it looses efficiency. This will produce savings in your energy bills and will need fewer repairs due to its ability to correctly cycle air through your home or business.
