In this post, we’re going to share 13 common symptoms that indicate your air conditioning unit may be oversized for your building, whether that be your business or home.

The 13 Warning Signs

If you have to face a hot day without a working air conditioner, you’re probably feeling miserable. What’s worse, an air conditioner that is oversized can display symptoms that can wreak havoc on the interior of your home or business. Here are the 13 most common symptoms of an oversized air conditioning unit:

  • Uneven building temperatures – If one room is colder than another at any given time, your unit may be cycling too many times throughout the day. The larger units work less but cool more, which means the cycles are happening too often or not often enough.
  • Noisy air ducts – Does it sound like you have a critter in your air ducts? What about a rattle or warble noise? An oversized AC unit may make odd noises due to it not having to work as hard to cool the building.
  • Whistling register noises – Whether it be whistling, humming, or otherwise, noises from the register are a sign something is wrong. In some cases, it could mean your unit is oversized.
  • Too little air – If not enough air is coming out of the register, there may not be enough pressure to feed the oversized unit.
  • Too much air – The opposite of too little air could be true, too. The unit could be working harder to provide air flow due to duct leaks throughout the system.
  • Frequent unit cycling – As mentioned above, an oversized air conditioning unit may cycle more often due to not having to work as hard as a properly sized unit to cool the building.
  • Component failures – Although a larger unit will cool a building with ease, the size can strain the unit in ways different than a regular or undersized unit. For example, the oversized unit may see more frequent failures with the compressor or furnace.
  • Inadequate filter performance – If your air filter seems to be underperforming, you may have an oversized unit. The more particles and dust captured in the filter makes it wear out faster.
  • Duct leakage – When you have an oversized unit and duct leaks, you will spend more on your utility bills and get less efficient cooling capabilities.
  • Increased maintenance costs – In most cases, a larger unit means more expensive maintenance costs for installation, repair services, and parts.
  • Shorter furnace/air conditioner lifespan – Although the unit is larger, it can go out quicker with the frequent cycling combined with duct leaks. Other problems already mentioned on this list can arise, costing you more in the long run.
  • Home pollution increase – An oversized unit can cause many issues with your air system. One is an increase in interior air pollution. Air quality can drop, causing mild allergic reactions and other health issues.
  • Mystery malfunctions – Using an improperly sized AC unit can lead to odd or mysterious part failures. This will cost you more in parts, repairs, and potentially an entirely new unit.
  • Dirty ducts and/or registers – If you notice dirty, dusty, or disgusting ducts, filters, or registers on your unit or in your system, it may be time to reevaluate the size of your air conditioner unit.

What size air conditioner do you need for your home?

Air conditioners come in various sizes and functions. There are three common methods to determine the perfect size for your home. AC units measure their ability to cool a building in “tonnage.” This tonnage is how HVAC experts determine which unit to install for your home or business. If your unit is too large, it simply means that its tonnage output exceeds the tonnage needed to cool your home.

When it comes to air conditioner units, size matters. Don’t let “HVAC experts” tell you otherwise. The goal is energy efficiency alongside cooling. Back in the 1980s, electricity was substantially cheaper, so a bigger unit, using more energy to cool a building quicker was the common approach for most air conditioner installations. However, now the goal is to use energy as efficiently as possible to get the cooling job done. If you have a unit that’s too large, you will be spending more money overtime to keep it running and to have it replaced.
