The Truth About AC Myths – What You Need to Know


When it comes to air conditioning systems, there are numerous myths and misconceptions that can lead to confusion and improper maintenance practices. In this blog post, we’ll debunk some of the most common myths related to AC repair and HVAC installation.

Myth #1: Closing Vents Saves Energy

Many homeowners believe that closing vents in unused rooms can save energy and reduce their AC repair costs. However, this is a myth. Your air conditioning system is designed to distribute air evenly throughout the entire ductwork system. Closing vents can actually put strain on the system, leading to inefficient operation and potential damage.

Myth #2: Bigger is Always Better for AC Units

It’s a common misconception that a larger air conditioning unit will provide better cooling. In reality, an oversized unit will cool your home too quickly, leading to frequent cycling on and off. This inefficient operation can increase energy consumption and wear down the system faster. The key is to have a properly sized unit for your AC installation that matches the cooling load of your home.

Myth #3: Air Conditioners Don’t Need Regular Maintenance

Neglecting regular maintenance is one of the biggest mistakes homeowners make with their air conditioning systems. Just like any other mechanical equipment, air conditioners require periodic cleaning, inspection, and maintenance to ensure optimal performance and longevity. Skipping maintenance can lead to decreased efficiency, higher energy bills, and premature system failure.


Debunking these common myths is crucial for homeowners to understand how to properly maintain and operate their air conditioning systems. By partnering with a reputable HVAC company like ATS Mechanical, you can ensure that your AC unit is installed correctly, serviced regularly, and operating at peak efficiency, providing you with reliable and cost-effective cooling for years to come.
