In this article, we will debunk some common AC myths and emphasize the importance of understanding these myths to avoid potential disadvantages. Should you find yourself in need of AC repair, replacement, or maintenance in Hamilton Township, NJ, Home Allegiance is here to help.

Six Air Conditioning Myths

It is important homeowners understand the do’s and don’ts when it comes to air conditioning systems, because a wrong practice can end up costing you more in the long run. Below we have listed six air conditioning myths and their disadvantages.

Myth: A Larger AC Unit is Better

One of the more pervasive myths surrounding air conditioning is that larger units will provide faster and more effective cooling of your home. Unfortunately, this is far from reality. AC units are designed to meet specific cooling needs for each space they serve. Installing an oversized AC unit may cause issues such as higher energy usage, uneven cooling distribution, and frequent on/off cycling cycles, as well as ineffective removal of humidity which causes an uncomfortable indoor climate.


  • Higher energy bills: An oversized AC unit consumes more energy to cool a space, leading to increased utility bills.
  • Inefficient operation: Oversized units tend to cycle on and off more frequently, causing wear and tear on the system and reducing its lifespan.
  • Poor humidity control: A bigger AC unit may not run long enough to effectively dehumidify the air, resulting in a clammy and uncomfortable indoor environment.

Myth: Regular AC Maintenance is Unnecessary

Another common misconception is that regular AC maintenance is unnecessary and can be skipped. However, neglecting AC maintenance in Robbinsville, NJ can have serious consequences. Regular maintenance helps identify minor issues before they turn into major problems, ensures optimal system performance, and improves energy efficiency.


  • Decreased efficiency: Lack of maintenance can lead to reduced AC performance and higher energy consumption.
  • Frequent breakdowns: Neglected AC units are more prone to breakdowns and AC repairs in Robbinsville, NJ, leaving you without cooling during the hottest days.
  • Reduced lifespan: Regular maintenance extends the lifespan of your AC unit, saving you from premature replacement costs.

Myth: Closing Vents in Unused Rooms Saves Energy

Some people believe that closing vents in rooms they don’t use will save energy by redirecting airflow to the occupied areas. However, modern AC systems are designed to work optimally with all vents open. Closing vents can disrupt the system’s balance, leading to increased pressure and potential damage to the ductwork. It’s best to keep all vents open for proper airflow and system efficiency.


  • Uneven cooling: Closing vents can create imbalances in airflow, resulting in uneven cooling throughout the house.
  • Increased strain on the system: The restricted airflow caused by closed vents can cause the AC system to work harder, potentially leading to breakdowns and increased repair costs.
  • Potential ductwork damage: Higher pressure in the ducts due to closed vents can result in leaks, cracks, or even collapsed ducts, leading to further inefficiencies and costly repairs.

Myth: Lowering Thermostat Temperature to Cool the Room Faster

Many people mistakenly believe that setting their thermostat to an extremely low temperature will quickly cool their room. However, AC systems work at a consistent rate regardless of temperature settings. Setting an extremely low thermostat only prolongs the cooling process and wastes energy.


  • Energy wastage: Lowering the thermostat excessively leads to longer cooling cycles, resulting in increased energy consumption and higher utility bills.
  • Overcooling and discomfort: Setting the temperature too low can lead to overcooling, causing discomfort and potential health issues.
  • Strain on the AC unit: Constantly running the AC at extreme temperatures can put unnecessary strain on the system, leading to premature wear and tear.

Myth: Running Fans to Keep the Room Cool

People often mistakenly believe that leaving a fan running in an empty room will help lower its temperature. In reality, all it does is circulate air and create a wind chill effect, causing a skin tingling and cooling sensation. Fans don’t reduce temperature and should always be turned off when no one is present to conserve energy and save energy costs.


  • Energy waste: Leaving fans running in unoccupied rooms consumes unnecessary electricity, leading to higher energy bills.
  • No actual cooling: Fans only create a breeze that makes you feel cooler but does not alter the room’s temperature.

Myth: DIY Air Conditioning Repair

Some homeowners may attempt DIY AC repairs in an attempt to save money. However, air conditioning systems are complex and delicate and need professional expertise for diagnosis and repair. DIY repairs often lead to further damage, safety hazards, and voided warranties, ultimately requiring further costly AC repairs in Freehold, NJ and surrounding areas.


  • Potential damage: Incorrect repairs can cause more harm to the AC system, leading to costly repairs or the need for a complete replacement.
  • Safety risks: Handling electrical components without proper knowledge and precautions can result in electrical shocks or fire hazards.
  • Voided warranties: Most manufacturers’ warranties become void if unauthorized repairs or tampering occur.
