3 Problems Caused by an Oversized Air Conditioner

Looking to replace an old air conditioning system? It is important to get an HVAC professional involved in the very beginning to help you find the correct size for the unit. Selecting the wrong size would mean many problems and a lot of air conditioning repair in Cupertino, CA for problems that are not easily fixed. The common problems with an oversized air conditioner include:

1. Increased Energy Bills

During the summer you already expect to pay higher energy bills. In an effort to save money some homeowners want to upgrade to a larger air conditioner, thinking it will cool faster and save them money. But an oversized air conditioner will only help to drive up cooling costs because it ends up working harder to cool the home than the correct sized unit would.

2. Air Conditioner Doesn’t Remove Humidity

To remove humidity from the air, the system has to run for a while. The air passes over the evaporator coil dropping to about 20 degrees Fahrenheit. Another important part of the process is that the coil is below the dew point and results in water vapor condensing on the coil. There has to be enough condensation on the coil to drip into the pan, and enough in the pan for it to drain. But if the moisture doesn’t have time to condense and drain, the air conditioning will not dehumidify the air.

3. Hotspots throughout the Home

An oversized air conditioner results in inconsistent cooling. The air does not fully disperse efficiently. And inconsistent airflow results in inconsistent temperatures. So while some rooms will feel plenty cool, others will be hot and humid.

4. Constant Short Cycling

If the air conditioner is operating efficiently a cooling cycle will usually last around seven to ten minutes. An oversized air conditioning unit will cool the air faster. This means the A/C is more prone to running for a much shorter period of time, frequently turning on and off. Anytime this happens the system runs the risk of overheating. So if an air conditioner has run on short cycles since installation, then it is likely to do not have the proper size.

5. Wear and Tear

An oversized air conditioner will likely suffer from premature wear and tear. Part of this is attributed to the short cycling. The short bursts of power have parts wearing out faster. These increases break downs and repair costs. And in turn, it shortens the lifespan of the air conditioning unit.
