The answer is YES if you are using a conventional air conditioner with a single speed compressor and motor.
All single stage air conditioning systems are in fact oversized at least 80% of the time. A properly designed HVAC system is designed to achieve the desired results on the hottest day of the year. But what about the other 80%-90% of the time that it is not the hottest day of the year? Well your system will be oversized during those times. Oversized systems lead to humidity problems, higher electric bills, and temperature swings in your home. So why would a reputable AC contractor install a system in your home that is oversized at least 80% of the time? Because that has been our only option for decades. The system must be able to cool the home on the hottest day of the year, therefore air conditioning contractors were left with no choice but to size the system accordingly. Air Conditioning contractors have been battling this issue for decades until the recent AccuComfort Technology was introduced. With this new technology the air conditioner is still designed to cool on the hottest day of the year, however it will adjust its own capacity according to the current inside and outside conditions to ensure that your system is always operating at the appropriate capacity.
Next time you are in the market for a new HVAC system, we highly suggest you consider an AccuComfort system. As more and more people become aware of this new technology, conventional systems will eventually become a thing of the past.
