Some Major Signs Your Air Conditioner Is Oversized

Selecting and installing the right air conditioner for your home is not easy, especially if you don’t consult an experienced air conditioning installation company. When fixing a new air conditioning system at your home, it’s best to avoid common AC unit installation mistakes with the help of a professional air conditioning installation service.

Most people are aware of replacing air filters regularly for the smooth operation of their air conditioning unit. Unfortunately, not many understand that the size of the AC system also matters. One of the most common mistakes people make when installing a new AC unit is by selecting an air conditioner that is too big for their home cooling requirements.

Below we will discuss some of the significant signs of an oversized air conditioner:

Shorter AC Cycles

An air conditioning unit’s cycle refers to the time it takes from the instance it’s turned on until it meets the desired temperature on your thermostat. At this point, the unit turns itself off because it has already achieved the intended room temperature on your thermostat. If you have an air conditioner that’s too big, it will cool down your home very fast. This creates much stress on your AC unit and reduces its useful lifespan.

Since an air conditioner that’s too large will take less time than usual to maintain the optimum temperature around the thermostat, it will shut down soon enough without cooling the entire space. On the other hand, an appropriately sized AC unit stays on for long enough to gradually meet your home’s cooling needs, giving it enough time to produce required cooling.

Temperature Discrepancies

An oversized air conditioner will have shorter and frequent cycles, causing serious temperature discrepancies. An AC unit that’s too big won’t be able to provide the desired cooling to your entire home. Thus, you’ll notice inconsistent temperature levels and increased discomfort in some parts of your house.

Increased Humidity Levels

Air conditioning systems that are too big don’t run long enough to dehumidify the entire air present inside your home. When AC units absorb the hot indoor air, water vapors condense on the AC coil and drip into the drip pan present beneath the coil. The moisture then exits the unit via a condensate drain line.

In the case of an oversized air conditioning unit, the cycle ends before the drip pan gets full of moisture, which results in evaporation and recirculation of the moisture back into your home. This ultimately leads to an increase in humidity levels inside your home.

Poor Air Quality

Every air conditioner consists of two sets of vents – one for emitting air and another for absorbing moisture. An AC unit that’s too large shuts off very soon; the indoor air doesn’t circulate properly, resulting in mold formation. If you observe an extraordinary presence of condensation or mold growth on your windows, it may indicate that your air conditioning system is too big.

Decreased Useful Lifespan And Increased Energy Bills

An oversized air conditioner suffers from excessive wear, corrosion, and depreciation due to shorter cycles. This results in requiring frequent air conditioning repairs and reduced useful lifespan of the AC system over the years. Besides that, an AC unit that is too large consumes disproportionate energy, which leads to higher utility bills.
