Why an Oversized Air Conditioner Is a Serious Problem

Are you in the market for a new air conditioning system, either as a replacement for an older, ailing AC or as part of your new home? Then it is very important that you have professionals involved in the installation process from the very beginning, not just for the actual few hours of work required to put the system in place and hook it up. You need the professionals to size the air conditioner so that works effectively and efficiently. If the air conditioner is too small, it will not provide the cooling your home needs. And if it is too large…

The problem with an oversized air conditioner

At first, it might seem like it’s impossible to put in an air conditioning system that is too powerful. Isn’t it simply better to be on the safe side of too much cooling rather than too little?

The answer is: no. An oversized air conditioner presents a number of problems that can be crippling and it will probably result in needing to replace the AC years before its time and wasting energy during the short period when it does run.

The basic problem with an oversized air conditioner is that it will start to short-cycle. Short-cycling refers to when an AC’s compressor turns on and off rapidly, never completing its cooling cycle. A number of issues in an air conditioning system can cause this. The reason that an oversized AC will short-cycle is that it will lower the temperature too fast so that the thermostat mistakenly believe it has reached its cooling goal. The thermostat then will shut off the compressor early, only to turn it back on again a short time later.

Short-cycling places excessive strain on the compressor as well as other components in the AC. This will create a large spike in air conditioning bills, as well as more repairs. Eventually, the over-stressed compressor will break down, and that often means the whole air conditioner must be replaced.

It’s easy to avoid an oversized AC installation: call on professionals for the job. OASIS Heating, A/C & Refrigeration, Inc. can provide you with an excellent air conditioning installation in Fairfax, VA.
