During some of the hottest summer days, homeowners in Kingsport, Johnson City, Bristol, and Southwest Virginia notice the same thing. Their AC runs constantly to keep up with their temperature setting. When temperatures climb into the upper 80s and 90s Fahrenheit and the humidity levels remain high, an air conditioner running all day is common.
In a lot of cases, these longer cooling cycles mean that your system has to work harder to make up the temperature difference. However, it’s important to be mindful of when longer run cycles are a sign of a malfunction.
Why Your AC May Need to Work Harder in Summer
Summertime throughout Southwest Virginia and Northeast Tennessee often brings a combination of high temperatures and heavy humidity. Your air conditioning system doesn’t just remove heat from your home, but it also removes moisture from the air. The combination of heat and humidity can put a bigger strain on your air conditioning system.
This holds especially true during the afternoon hours when temperatures are at their hottest. Your air conditioner may run longer when the outdoor temperatures are higher and after you open your doors. You may notice your AC is running after household activities like doing the laundry or cooking because they generate indoor heat.
When Constant Operation Could Mean Trouble
Recognizing the key signs that your long AC run time is due to an underlying issue allows you to seek out AC repair sooner rather than later. If your air conditioner is running all day but never getting your home to your desired temperature, it has a problem. If you experience warm air coming from your vents or there’s weak airflow, there’s an issue.
High indoor humidity, high cooling bills, and ice on your refrigerant lines require professional air conditioner repair. If you notice any of these issues, they’re causing your system to lose efficiency. It’s best to seek out AC repair in Kingsport, TN, before the issue gets any worse.
Dirty Air Filters Can Restrict Your AC’s Cooling Capacity
One of the most common causes of longer AC run times is a dirty air filter. As it collects dust, pet hair, pollen, and other debris, airflow becomes restricted, forcing your system to work harder. Regular AC maintenance, including checking and replacing your air filter, helps improve airflow, restore efficiency, and prevent unnecessary strain on your system.
Low Refrigerant Can Keep Your AC Running
Low refrigerant is another common cause of longer AC run times. Refrigerant absorbs heat from inside your home and releases it outdoors, so low levels reduce your system’s cooling ability. Since refrigerant doesn’t get used up, low levels usually indicate a leak. A Tri-Cities HVAC contractor can locate the leak, repair it, and recharge your system to restore cooling performance.
Inadequate Airflow Leads to Poor Cooling Performance
For your air conditioning system to operate efficiently, it needs unrestricted airflow. Blocked vents, closed registers, dirty air filters, failing blower motors, dirty evaporator coils, and damaged ductwork can all restrict airflow. When air can’t circulate properly, your AC will struggle to reach the thermostat setting. Professional airflow testing can identify the problem and restore proper system performance.
Leaky Ductwork Could Be Wasting Your Cool Air
Another potential culprit of your cooling system inefficiency is leaky ductwork. If there are leaks anywhere throughout your ductwork in your attic, crawl space, basement, or walls, conditioned air can escape while hot, humid air comes in. This leads to uneven temperatures, high cooling bills, and longer run times. Getting AC repair in Johnson City, TN, for your ductwork is the key to restoring performance.
Thermostat Problems Can Cause Continuous Operation
Sometimes, the problem may not actually be your HVAC system but rather your thermostat. An incorrectly programmed or malfunctioning thermostat can cycle improperly, continue calling for cooling when it’s unnecessary, and read temperatures inaccurately. If you suspect that you have a thermostat malfunction, it’s best to call for prompt AC repair in Bristol, TN.
An Aging System Could Be to Blame
Even the most well-maintained home cooling systems will lose efficiency as they get older. If your existing air conditioning system is between 12 and 15 years old or older, it could struggle every summer. Opting for a cooling system replacement may be the ideal choice to enhance your indoor comfort.
