Short-Cycling—A Common AC Problem to Watch For!

Monday, May 6th, 2024 at 11:00 am


As an HVAC contractor at Climate Masters, we know how important it is to maintain your air conditioning system for optimal performance and energy efficiency. One of the most common issues we encounter in AC units is short-cycling. In this blog post, we’ll explore what short-cycling is, why it’s a problem, and the main causes behind it. By the end of the post, you’ll have a better understanding of how to spot and address this issue with AC repair in Elkton to keep your home cool and comfortable.

What Is Short-Cycling?

Short-cycling occurs when an air conditioning system turns on and off too frequently, running in shorter bursts instead of completing its full cooling cycle. This can happen due to various reasons, and it can have a significant impact on your AC’s performance and lifespan. Instead of providing consistent cooling, the unit struggles to maintain a steady temperature, which can result in several problems.

Why You Don’t Want Short-Cycling

Reduced Efficiency: Short-cycling leads to poor energy efficiency. Your AC uses more energy when it turns on and off frequently, causing your electricity bill to skyrocket.

  • Increased Wear and Tear: Constantly starting and stopping takes a toll on your AC’s components. This can lead to premature wear and tear, resulting in more frequent repairs and a shorter lifespan for your unit.
  • Poor Comfort: An AC that short-cycles struggles to maintain a consistent indoor temperature. You may notice temperature fluctuations and hot or cold spots in your home, making it less comfortable.
  • Higher Risk of Breakdowns: The strain on your AC due to short-cycling increases the likelihood of sudden breakdowns. This can be costly and inconvenient, especially during the hot summer months.

Main Causes of Short-Cycling

Now that you understand the impact of short-cycling, let’s explore some of the main causes behind this common AC problem:

  • Oversized AC Unit: One of the most common causes of short-cycling is having an oversized AC unit for your home. An oversized unit cools your home too quickly, causing the system to shut off prematurely. This leads to frequent on-and-off cycles.
  • Thermostat Issues: Faulty thermostats can send incorrect signals to your AC system, causing it to cycle on and off unnecessarily. This can happen if the thermostat is malfunctioning or improperly calibrated.
  • Refrigerant Leaks: Low refrigerant levels due to leaks can cause your AC to work harder to maintain the desired temperature. This struggle can result in short-cycling as the system tries to compensate for the lack of refrigerant.
  • Clogged Air Filters: Dirty or clogged air filters restrict airflow, making it difficult for your AC to cool your home efficiently. This strain on the system can lead to short-cycling.
  • Electrical Issues: Problems with your AC’s electrical components, such as the compressor or capacitors, can cause short-cycling. These issues can disrupt the normal functioning of your AC system.
  • AC Is Too Old: If your AC is old and has been experiencing short-cycling, it may be time to consider a replacement. An aging AC unit may no longer operate efficiently, and short-cycling could be a sign that it’s reaching the end of its lifespan.
