The Truth Behind HVAC Myths Busting Common Misconceptions


When it comes to heating and cooling systems, there are numerous myths and misconceptions that can lead homeowners astray. At Service Now! Heating and Air Conditioning, we believe in empowering our customers with accurate information to help them make informed decisions. In this blog post, we’ll debunk some of the most common myths about air conditioner repair, installation, and overall HVAC maintenance.

Myth #1: Bigger is Always Better

One prevalent myth is that bigger air conditioning units are more efficient and effective at cooling your home. However, this is not entirely true. An oversized unit may cool the space quickly, but it will cycle on and off more frequently, leading to higher energy consumption and premature wear and tear on the system.

The key to optimal performance lies in proper sizing. A professional HVAC contractor will assess your home’s square footage, insulation levels, and other factors to determine the right-sized unit that can efficiently cool your living space without wasting energy.

Myth #2: Closing Air Vents Saves Energy

Some homeowners believe that closing air vents in unused rooms can help save energy and lower utility bills. Unfortunately, this myth is far from the truth. Closing vents can disrupt the balance of your HVAC system, causing it to work harder and potentially leading to premature failure.

Instead of closing vents, it’s recommended to keep them open and set the thermostat to a comfortable temperature throughout the home. This allows for proper airflow and efficient operation of your HVAC system.

Myth #3: Air Conditioning Maintenance is Unnecessary

  • Annual maintenance checks are crucial for the longevity and efficiency of your HVAC system.
  • Regular maintenance helps identify and address potential issues before they escalate into costly repairs.
  • It also ensures that your system is running at optimal efficiency, reducing energy consumption and utility bills.

Neglecting maintenance can lead to a variety of problems, including decreased efficiency, premature system failure, and even potential safety hazards.
