Is Your AC Short Cycling? Here are some Causes and Solutions

Have you ever noticed that your air conditioning unit turns on and off a lot? If so, you're not alone. Many homeowners experience this issue, which is known as AC short cycling. But what causes it, and more importantly, how can you fix it? At times, you may be able to resolve the issue with minor fixes. However, you may need to call in an HVAC maintenance technician in Newnan in case the problem is something big.


So here is a closer look at why AC short cycling is a problem, what causes it and how to fix it. 


Why is short cycling bad news?


Usually, your AC will run through three cooling cycles every hour to keep your home cool. When the temperature within your home rises, the thermostat activates the AC to begin working. The compressor responds by turning on and using the refrigerant to cool the warm air passing through it. Within 10-15 minutes, the temperatures will cool down to the level you have set, and the AC will automatically turn off until it is time to work again.


This functioning is totally disrupted when there are issues with your HVAC system. The compressor stops working before completing the cooling cycle. With time, the cycles become shorter and more frequent, leaving you with a hotter home, higher electricity bills and potentially shorter HVAC lifespan.


Common causes of AC short cycling


There are many reasons why your AC may be short cycling. Only an experienced HVAC maintenance expert  in Newnan will be able to find the precise reason. Some of the common causes of AC short cycling include:

1) Clogged air filter


When the air filter is clogged with dust and dirt, it will seriously affect the airflow and cause overheating of the system. In most cases, overheating will lead to short cycling as well. You can easily fix this issue by cleaning air filters regularly and changing them every three months.

2) Low refrigerant levels


The refrigerant in the HVAC system is responsible for transferring heat from the interiors to the outside via the evaporator coils. Usually, air conditioners come equipped with sufficient refrigerant to keep them working throughout their lifespan. But if there has been a leak and the refrigerant levels have decreased, your AC will be unable to cool the air, leading to overheating and short cycling. An HVAC maintenance technician in Newnan can help you deal with this issue by identifying leaks, if any and topping up the refrigerant.

3) Frozen evaporator coils


If you are running the AC while it is extremely cold outside, the evaporator coils in the AC can freeze up. Sometimes, a malfunctioning unit or clogged filter too can cause the freezing of evaporator coils. The right way to deal with the issue is to switch off the system and give it time to thaw completely before turning it on again. If that does not work, call your HVAC maintenance technician in Newnan.

4) Oversized HVAC system


If your air conditioner is above the recommended size for your home, there is a chance that it might overrun the temperature you have set, end the cycle and then turn on again when temperatures rise. There are no shortcuts to resolving this issue. You need to get the AC replaced with one that is right for your home size.


Regular AC maintenance can help solve the problem


Even if your AC does not have any of these issues, you could still experience short cycling if the AC is an old one. This is because advancing age can adversely affect the efficiency of its components. Consult a reputed HVAC maintenance expert in Newnan to find out if it is time to replace any components in your HVAC system or if you need to invest in a new AC.


Remember that the most effective way to prevent AC short cycling is to get your AC regularly maintained by an HVAC professional.

Winter blackouts, especially during ice storms, can bring life to a standstill, leaving families vulnerable to freezing temperatures and disrupted routines. Ice storms are particularly dangerous, as freezing rain can build up on power lines and trees, causing outages and hazardous conditions. Losing power for just 4 to 5 hours in these conditions can create serious challenges, especially for families with pets, babies, or individuals relying on medical devices. Impact on Those in the Home Pets are highly sensitive to temperature drops, particularly for smaller or short-haired breeds. Without heat, they may struggle to stay warm, risking illness. To prepare, keep extra blankets or bedding for them and consider portable, pet-safe heating options. Ensuring your pets remain comfortable during an outage is crucial for their health and safety. For babies, maintaining a warm environment is essential for their well-being. Without heat, dress them in layers and use portable heating pads. Having these preparations ready ensures your little one stays safe and comfortable during a power outage. For individuals who rely on medical devices, power outages can be a serious concern. Devices like oxygen concentrators or CPAP machines require uninterrupted power. Additionally, medications that need refrigeration must be protected. Backup power solutions, such as battery systems or whole home generators, can help avoid emergencies during extended outages. The Importance of Knowing Your Power Status Staying informed about your power status is a vital part of winter preparedness here in Georgia. Many utility companies offer apps and alerts that let you track outages, assess restoration times, and plan accordingly. This information helps you decide if relocating temporarily or relying on backup power is necessary. Generac Generators: A Reliable Solution Investing in a Generac generator is one of the most effective ways to safeguard your Austell, Griffin, Newnan, and Stockbridge home during winter outages. These generators provide continuous power, keeping heating systems, lights, and essential devices up and running.

Living in areas like Austell, Stockbridge, Newnan, and Griffin means enjoying a variety of home styles, from charming older houses to modern builds. However, regardless of your home's age, electrical outlets can sometimes stop working, leaving you scratching your head. Here are some common reasons why an outlet might stop functioning, and how Hammond Services can help with electrical issue resolution and electrical safety inspections. 1. Tripped Circuit Breaker One of the most common causes of a non-working outlet is a tripped circuit breaker. Circuit breakers are designed to protect your home from electrical overloads. If you’ve been using multiple high-powered devices like space heaters, hair dryers, or kitchen appliances in one area, the breaker might have tripped to prevent overheating. Locate your breaker box, look for a switch that’s out of alignment, and reset it by flipping it off and then back on. If the breaker trips again, it’s time to call a professional to assess the circuit’s load capacity and ensure electrical safety in your home. 2. GFCI Outlet Reset Needed If your outlet is near water—like in kitchens, bathrooms, or outdoor areas—there may be an issue with a Ground Fault Circuit Interrupter (GFCI) outlet. GFCI outlets are designed to cut power when they detect moisture or a surge, protecting you from electrical shocks. These outlets have a reset button that pops out when they trip. Simply press the button to reset it. If resetting doesn’t restore power, the GFCI itself may be faulty, or there could be another electrical issue in the circuit. For additional tips on improving your home’s electrical safety and efficiency, check out this article from Hammond Services: What Electricians Can Do for Homeowners. 3. Loose Wiring or Connections Outlets can stop working due to loose or damaged wiring, especially in older homes. Over time, wires can degrade, leading to poor connections that may cause the outlet to fail. This electrical issue can create a safety hazard, including the risk of electrical fires. A professional inspection can identify and resolve these problems, ensuring your home remains safe and functional. 4. Faulty Outlet Over time, outlets can wear out, particularly if frequently used. If your outlet has been heavily used or is outdated, it may simply need replacing. Frequent plugging and unplugging can cause wear and tear, eventually leading to failure. Hammond Services provides reliable outlet replacement services, prioritizing electrical safety in every upgrade. 5. Hidden Issues If you’ve checked the breaker and reset your GFCI but the outlet still doesn’t work, there could be deeper wiring issues at play. Sometimes the problem isn’t with the outlet itself but lies deeper within your electrical system. Faulty wiring, overloaded circuits, or even pest damage can cause disruptions. If your outlet still doesn’t work after checking the breaker and GFCI, it’s best to have a professional electrician diagnose the electrical issue and ensure your home’s electrical safety.
