Does a larger A/C Unit offer better performance? | Day & Night Air

This year is the year, and you’re finally going to upgrade your home’s air conditioning unit. In fact, you’re going to go the distance and get an even bigger AC unit! Bigger should mean better, right?

Believe it or not, this is not necessarily the case. There are a few reasons why getting your AC unit size just right is important.

 

Overall Costs

The first and most obvious reason not to get an oversized AC unit is because they cost more, and of course you want to save money, right? A bigger unit costs more to purchase, but you’ll also see increased operating costs. Bigger AC units cost more to run, even if they don’t run for as long. In fact, as we’ll see next, not running for as long can cost you more down the road, too.

 

Wear and Tear

The wear and tear on the system is another reason why getting the air conditioning unit size right is so important. Larger AC units may cool your home faster, but that means the cooling cycle will end faster and they will shut down faster - only to cycle back on again before very long. This rapid cycling creates a lot of wear and tear on the system, shortening its life and increasing the maintenance needed to keep it running.

 

Cooling Effectiveness

While perfect and even cooling throughout the house is not always possible, an oversized AC unit is bound to make these patterns even worse than before. When a cooling system is too big, it cools the house too rapidly, which results in the system running only for very short periods of time. These short cooling cycles also mean that the system doesn’t have a chance to properly circulate the cool air throughout the house, resulting in some areas being better cooled than others.

 

Dehumidifying

Phoenix AC service professionals deal with this less than those in more humid areas, but it’s still worth mentioning that the shorter air conditioning cycles also result in the AC doing a less effective job of dehumidifying. Moisture is removed from the air when it condenses on the cold evaporator coil, eventually dripping into the drain pan and flowing out of the house. The shorter cycles of an oversized AC unit don’t provide enough time for this to happen effectively or completely.
