Clearing the Air on Common AC Myths


When it comes to air conditioning systems, myths and misconceptions tend to circulate freely. At Shoreline Air Conditioning, we believe in empowering our customers with accurate information. In this blog, we’ll debunk some common myths related to AC service, repair, and installation.

Myth #1: Closing Vents Saves Energy

Many people believe that closing vents in unused rooms can help save energy. However, this practice can actually increase your energy costs. Air conditioning systems are designed to circulate air throughout the entire home or building. When vents are closed, it creates an imbalance in the system, causing it to work harder and use more energy.

Myth #2: Bigger is Always Better

  • Oversized air conditioning units are not more efficient.
  • They tend to cycle on and off more frequently, leading to uneven cooling and increased wear and tear.
  • A properly sized unit based on square footage and insulation levels is essential for optimal performance and energy efficiency.

Myth #3: AC Units Don’t Need Regular Maintenance

This myth couldn’t be further from the truth. Regular maintenance is crucial for ensuring your air conditioning system runs smoothly and efficiently. Neglecting routine maintenance can lead to breakdowns, inefficient operation, and higher energy bills. At Shoreline Air Conditioning, we recommend scheduling annual tune-ups to keep your system in top shape.


By debunking these common myths, we hope to provide you with a better understanding of how to maximize the efficiency and lifespan of your air conditioning system. Remember, reliable information from trusted professionals is key to making informed decisions about your comfort and energy costs.
