When you are shopping for an air conditioning unit, one of your most important questions will be how powerful of a unit you need for your home. You may think that more power equates to better cooling capabilities and a more comfortable home environment. However, air conditioning units that are too powerful for a home come with a multitude of problems. Below are some of the main problems you will face if you purchase a unit that is too powerful.
The more powerful an air conditioning unit is, the more expensive it will be to purchase, install, and maintain. If you purchase a unit that is too large for your home or for the room that you intend to cool in your home, then you will not only be spending more money upfront but also more money to maintain it over the years. This is because overly large units tend to cycle on and off more often than properly sized units, which can cause extra wear and tear on the parts in your air conditioning unit.
An air conditioner that is too powerful for its intended space will quickly cool a room, slightly below your intended temperature due to its excessive force. The unit will then turn off and the temperature in your space will slowly increase until the unit turns on again. This can result in wide fluctuations of temperature throughout the day. However, if you have a properly sized unit, it will remain on throughout the day, keeping your room at the temperature you have chosen on your thermostat.
Extra Energy Expenditure
An air conditioning unit uses the most energy when it turns on. Because units that are too-powerful for a space can quickly cool the area and then turn off, they will turn on more often throughout the day. Because of this, you may notice an increased energy expenditure compared to running a smaller unit constantly.
An Overly Humid Indoor Environment
An air conditioning unit not only chills the indoor air but also removes humidity from the air. However, if you have a unit that is too powerful for your home, then the unit will quickly blast cold air into your home and will not have enough time to remove the humidity from the air before your home reaches your set temperature and the unit turns off. As this happens several times throughout the day, humidity will slowly build up. Eventually, this will result in a cold, clammy environment instead of a fresh, crisp coolness in your home.
In addition to feeling clammy, the extra humidity in your air can contribute to mold and mildew problems if these are already an issue in your home.
Modern air conditioning units are relatively quiet. However, the bigger they are, the louder they are. This means that you will have an unnecessary noise level the entire time your air conditioning unit is operating. While you will likely not notice the noise if it is constantly there throughout the day, because of the extra cycling of overly-powerful units, the noise will come and go throughout the day, making it more noticeable and likely more annoying for people in your home.
To avoid getting an overly-powerful air conditioning unit, you should check the energy star recommendations for the size of your home. However, if your home uses passive heating and cooling methods, you may need a slightly smaller unit, and if you live in a very hot area, you may need a slightly larger unit. For this reason, it is important to consult with a professional who is experienced installing air conditioners in your area.
