Even during summertime heat waves, your air conditioning system should still be able to maintain your interior temperature. On the hottest days, it may run for longer cycles to accommodate your cooling needs. However, if your AC is constantly struggling to get your home cold, something isn’t working right. If you’re asking yourself, “Why is my AC not keeping up with the thermostat,” there are several factors you should consider.
From refrigerant leaks and dirty air filters to systems that are too small, many different issues can reduce your system’s cooling performance. Ignoring these warning signs can lead to increased system wear and tear, costly breakdowns, and higher energy bills. Getting to the root cause of why your AC is struggling can help you make a better-informed decision about what to do next.
How Extreme Heat Affects Your AC’s Ability to Reach the Set Temperature
Throughout periods of extreme heat, your AC unit will need to run longer to get your home to your desired temperature setting. Most residential air conditioning systems can maintain indoor temperatures that are about 15 to 20 degrees cooler than the outdoor temperature. When temperatures climb above this range, it’s normal for your system to struggle a bit with keeping your home comfortable.
However, if your home never reaches your desired temperature setting, the AC could have some underlying issues. Low refrigerant, blocked condenser coils, and dirty air filters can all be to blame. Getting routine AC maintenance is one of the best ways to prevent many of these issues before the worst of the summertime heat arrives.
Common Reasons Your AC Cannot Keep Up
If your air conditioning system is struggling to keep up with your cooling demands, there could be several reasons. These include dirty coils, a dirty air filter, worn components, frozen coils, or low refrigerant levels. Your unit may be the wrong size or aging, which could reduce its operating performance.
As your air conditioning system runs, it filters unwanted contaminants out of your air. Over time, the filter fibers become clogged by dust and other debris, restricting airflow throughout your system. This reduces cooling performance and could freeze evaporator coils.
Both your evaporator and condenser coils are responsible for transferring heat in and out. If the surface of your coils has grime or other dirt, it acts as a barrier that restricts their ability to move heat. This could dramatically decrease the performance of your air conditioning system.
If you simply ignore these problems, you could face higher energy bills, a greater breakdown risk, and increased wear on your system. Professional AC repair services can diagnose the underlying cause of your inefficiency issue. We can get to work restoring your system’s performance and recommend when an upgrade may be necessary.
How Airflow and Ductwork Problems Affect Cooling
To effectively cool your home and keep it comfortable, proper airflow is a must. If you have supply vent obstructions, leaky ductwork, or a dirty air filter, your system has to work harder. Poor airflow can lead to reduced energy efficiency and hot and cold spots throughout your home. It can also make it difficult to reach your thermostat setting.
Some common signs of failing ductwork include uneven room temperatures, weak airflow, and excessive dust. You may notice rising energy bills and a whistling noise coming from your ducting. Poor duct sealing or damage to your air ducts allows cool air to escape before it ever reaches the main rooms of your home. A professional duct inspection can help identify airflow issues and restore performance to your cooling system.
When the Thermostat May Be Part of the Problem
One culprit behind why your AC may not be functioning optimally is your thermostat. If your thermostat has dead batteries, incorrect settings, a faulty sensor, or poor placement in your home, it could lead to a system malfunction. If you have an outdated thermostat, upgrading to today’s home thermostat options, like smart thermostats, can help. Doing so will improve your comfort, your system’s energy efficiency, and temperature control.
Both smart and programmable thermostats offer advanced scheduling features and more precise system operation. This allows your HVAC system to perform at its best. If you’re unsure whether your thermostat is working properly, an evaluation from a professional HVAC technician is in order.
What to Check Before Scheduling AC Service
Before you schedule professional service, there are a few things you can check on your own to attempt to troubleshoot your cooling system. Ensure your thermostat is set to cool and the temperature is lower than your room temperature. You can check your air filter and replace it if it’s dirty.
Confirm that all your supply and return vents are completely open and unobstructed. Also, check around your outdoor condenser unit, removing any grass, leaves, or other debris that could restrict airflow. You can check your circuit breaker to see if you need to reset it.
