At United Air Conditioning, we understand the importance of reliable and efficient heating and cooling systems. However, there are many myths surrounding HVAC (Heating, Ventilation, and Air Conditioning) systems that can lead to misconceptions and poor maintenance practices. In this blog post, we’ll debunk some common myths and provide you with accurate information.

Myth #1: Closing Vents in Unused Rooms Saves Energy

Many homeowners believe that closing vents in unused rooms will save energy by preventing conditioned air from entering those spaces. However, this is not true. HVAC systems are designed to distribute air evenly throughout your home, and closing vents can actually increase the workload on your system, leading to higher energy costs and potential damage.

Myth #2: Bigger HVAC Systems are Better

It’s a common misconception that larger HVAC systems are more efficient and effective. In reality, an oversized system will cycle on and off more frequently, leading to uneven temperatures and higher energy consumption. A properly sized system, installed by professionals, will provide optimal comfort and efficiency.

Myth #3: Air Conditioning Units Only Need Maintenance Once a Year

This myth can lead to serious consequences for your HVAC system. Regular maintenance is crucial for ensuring optimal performance, energy efficiency, and longevity. We recommend scheduling professional maintenance at least twice a year – once before the cooling season and once before the heating season.

  • Benefits of regular maintenance include:
    • Improved indoor air quality
    • Lower energy bills
    • Extended equipment lifespan
    • Fewer breakdowns and repairs


At United Air Conditioning, we strive to provide our customers with reliable and efficient HVAC solutions. By debunking these common myths, we hope to empower you with accurate information to make informed decisions about your heating and cooling needs. Remember, proper maintenance and professional installation are key to ensuring your comfort and saving money in the long run.
