When your air conditioner seems to be running non-stop—even on moderate days—it’s not just a minor annoyance. A constantly running AC system can lead to sky-high energy bills, uneven indoor temperatures, and accelerated wear on your equipment. If you’re in Rockwall, TX and your AC just won’t quit, it’s time to figure out why it’s overworking—and what you can do to solve it.
At Apple AC & Heat Services, we’ve seen this issue in homes of all sizes. Whether it’s a quick fix or a sign of deeper inefficiency, we’re here to help restore your comfort and cut your costs. Let’s explore the common reasons your AC is running constantly and what steps you can take to fix it.
1. Your AC Unit Is Too Small for Your Home
If your AC system is undersized, it may not have the capacity to cool your entire home efficiently, especially during the peak of a Texas summer. That means it has to run continuously just to try (and fail) to keep up with your desired temperature.
The fix: Schedule a professional system inspection. We can perform a load calculation to determine if your current system is properly sized and recommend the best cooling solution—whether that’s a larger system or a zoned cooling approach like a ductless mini-split.
2. Dirty Air Filters Are Choking Airflow
One of the most common and easily overlooked issues is a clogged air filter. When filters are full of dust and debris, air struggles to move through the system. Your AC has to work harder and longer to cool your home.
The fix: Check and replace your air filters every 1–3 months, especially in summer. A clean filter allows air to move freely and helps your AC cool more efficiently.
3. Refrigerant Levels Are Low or Leaking
Refrigerant is essential for removing heat from your indoor air. If your system is low due to a leak, it won’t cool effectively. This leads to longer run times as the system tries to reach the set temperature.
The fix: Call in the pros for an AC inspection and refrigerant check. If there’s a leak, our licensed technicians will locate it, repair it, and recharge your system to restore full cooling performance.
4. Your Thermostat Is Misreading Temperatures
A faulty or poorly placed thermostat can cause your AC to run longer than necessary. If it’s near a window or heat source, it may sense the home as warmer than it actually is.
The fix: Check your thermostat’s location and replace the batteries if needed. For optimal control, consider upgrading to a smart thermostat, which can improve efficiency and help lower your monthly cooling bills.
5. Leaky Ductwork Is Losing Cool Air
If your ducts are leaking, a portion of your cooled air never reaches your living spaces—it escapes into attics, walls, or crawl spaces. This forces your AC to run longer to achieve the same cooling effect.
The fix: Schedule a duct inspection and sealing service. Sealing leaks helps air reach every room efficiently and reduces strain on your system.
6. Your AC Needs a Mid-Summer Tune-Up
A system running non-stop may simply be overdue for a maintenance check. Dirty coils, aging parts, and low lubrication levels can cause your unit to work overtime.
The fix: Book a mid-summer HVAC tune-up with Apple AC & Heat Services. We’ll inspect, clean, and optimize your system so it can cool your home without wasting energy.
