Oversized Air Conditioner Problems

Are you starting to believe that your air conditioner is too big?

If that is the case, it is likely that you will experience at least one of the following three problems if your air conditioner is too large for your home:

  • You are paying higher utility bills.
  • Your air conditioner begins to operate immediately and shuts down after a while.
  • Your air conditioner is not removing humidity.

In this article, we’ll go over each of these issues in greater depth, as well as discuss how to resolve them.

Problem#1 : Your energy bills are increasing.

The fact is, an oversized air conditioner will frequently cool your home extremely quickly before shutting down.

Not only does this cause wear and tear on your air conditioning components (because of the constant on and off cycling), but it also has the potential to raise your energy bills.

Your air conditioner is equipped with several motors that drive various components (like the compressor and blower). Furthermore, all of these motors consume more power when they are first turned on than they do when they are running. As a result, if your air conditioner cycles on and off frequently, the motors in your air conditioner are drawing more power than they should, increasing your energy bills.

In other words, if you’ve noticed a steady increase in your energy bills, it’s possible that your air conditioner is too big.

Problem #2: Your air conditioning turns on and off immediately.

Is your air conditioning system capable of cooling your home in 10 minutes or less on a hot afternoon?

If this is the case, it is possible that you have an oversized air conditioner.

Because an oversized air conditioner is too powerful for your home, it will quickly cool your home before shutting down, raising your energy bills and wearing out your air conditioner (from all the starts and stops).

Problem#3: Your air conditioner isn’t effectively removing humidity.

One of the critical functions of your air conditioning system is to remove humidity from the air in your home, which is particularly important during the hot summers in South East Houston and Harris County.

The evaporator coil (which is located in the indoor air handler) is responsible for removing moisture from warm, moist air. The moisture is then expelled from your home through the condensate drain.

Indoor humidity levels of 30–50 percent should be achieved with a properly sized air conditioner. However, in order to dehumidify the air in your home, your air conditioner must run on normal-length cycles.

As we discussed previously, an oversized air conditioner will cycle on and off on a regular basis. Furthermore, if your air conditioner is constantly shutting down, it will not be able to run long enough to remove moisture from the warm air in your home.

As a result, if your home is extremely humid, it is possible that your air conditioner is oversized.

How did you end up with an oversized air conditioner?

So, to cut a long story short, it’s most likely because the technician who installed your air conditioner didn’t perform a “cooling load calculation.”

A cooling load calculation takes into account a variety of variables, including:

  • The size of your house in terms of square footage
  • The number of bedrooms and bathrooms in your house
  • Count the number of windows and doors in your residence.
  • The climate in which you live

An Air Check Mechanical Service technician can only provide an accurate recommendation for the appropriate AC size for your home if he or she considers all of the factors listed above. Unfortunately, many HVAC technicians either do not know how to perform a cooling load calculation or simply do not perform one when installing a new air conditioner.

Why would a technician choose to forego performing a cooling load calculation?

Consider this: your old air conditioner weighs 3 tons. You might be under the impression that you should simply replace the 3-ton air conditioner with a new 3-ton system.

For example, what happens when your old 3-ton unit was already too large for your house? Essentially, you’re just replacing one oversized unit with another oversized unit, which means you’ll be dealing with the same problems as before.

Air Conditioning Replacement Vs. Repair

Oh, how our consumer-driven and capitalist society has always encouraged us to go for new! New is always best! Why exert too much effort in repairing something when you can just buy a replacement that you can rely on to better serve you? I hate to burst my own bubble here, but unfortunately, most Americans may not really have the bottomless amount of financial resources to fund a penchant for continually new things. On the topic of HVAC systems, this becomes all the more crucial as these equipment is not really the cheapest items you can buy at the supermarket to replace your current on. So, the question stands – Should you go for an AC replacement or just a repair your central air conditioner? Actually, there are a number of factors to consider when mulling this question. There’s your system’s lifespan. Has your system given you a great deal in terms of return on investment? Is the cost of repairing your system almost as high as a replacement for the entire system?
