Problems with Installing an Over-Sized Air Conditioner

You may think that bigger is better but that’s not the case when it comes to HVAC equipment. An air conditioner that provides more power than necessary for your space can lead to big problems. Read on to see how a unit that’s too large can affect your indoor air quality, comfort, wallet and more.

Short cycling

If your AC is “short cycling,” it’s turning off early, before it’s had time to complete a full cooling cycle. This happens when the unit is too powerful, cooling your home quicker than needed. Short cycling not only puts unnecessary stress on your equipment but because it occurs over and over all day long, it causes your energy bills to skyrocket.

Higher cost

Not only will you see higher energy bills with an over-sized unit, you’ll likely pay more upfront for the equipment and the installation because of the larger size.

Temperature variations

An air conditioner that is too big will cause major temperature variations throughout the different areas of your home. Because of short cycling, one room may cool quickly while others are left warm. Properly sized equipment will cool your home evenly, over time leading to optimal comfort levels.

Inadequate dehumidification

Since it doesn’t have to go through a full cooling cycle to lower the temperature, an over-sized air conditioner doesn’t have the proper amount of time or airflow to adequately dehumidify your home. This leads to a muggy, damp and clammy indoor environment. Not only is this a major discomfort, it can leave your house smelling musty.

Improper air filtration

Because of shorter run-times, air is not filtered properly which can lead to a decrease in indoor air quality, putting you and your family at risk for health problems.

Shorter lifespan

Due to unnecessary wear and tear, your over-sized equipment will likely break down quicker than a correctly sized unit would. You’ll end up paying more in repairs and may actually need to replace your unit well before you expected.

It’s easy to avoid these problems when you work with a trusted HVAC company who will recommend a properly sized air conditioner based on careful calculation. Contact Crown Group to get a new AC quote in Akron or Canton, Ohio.

The Dangers of Using Window AC Units in the Summer

Though they may be convenient and cheaper than installing central AC, window air conditioning units present many dangers to you and your family.

Window Unit Dangers

  • Mold – A window AC unit is the perfect breeding ground for mold because of the humidity that the unit draws from the air. This can upset allergies and even make you or one of your family members extremely sick.
  • Home safety – While they may provide cool air to your room, they also may make the home prone to burglary. If the unit isn’t installed correctly, it’s easy for a burglar to remove it and get into your home.
  • Fire hazards – If there is a fire in your home, specifically in the same room as your window unit, it can easily become dislodged and fall, causing further damage. Related, if the unit is installed in the room’s only window and there is a fire, it will be difficult for you or your loved ones to escape using the window.
  • Outdoor air infiltration – Any seal in the between the air conditioner and the unit that is broken will allow outdoor air (and all of the pollutants found in it) to seep into your home. This can negatively affect your home’s indoor air quality.

Window AC Unit Safety Tips

If you absolutely need to use a window air conditioner, utilize these tips:

  • Always have a certified professional install window units.
  • Burglar proof your window unit by ensuring it is installed utilizing the proper support and equipment.
  • Be sure the right sized unit is being used. Before purchasing the unit, measure the window and check out the power supply near the window.
  • Be sure the unit is installed so that it doesn’t move when someone opens the window or secure it so that the window can’t be opened at all.
  • Remove the front panel monthly during cooling season in order to clean the filter.
  • Don’t leave the unit in your window over the winter as it can cause drafts. Store your unit in your basement or attic, not the garage as it may make it easier for rodents to find their way into the unit.

Window AC Unit Alternatives

The best alternative to a window AC unit is to install central air conditioning in your home.  While the cost may be greater, the benefits significantly outweigh those of a window unit.
