Why Is My Concord Air Conditioning Running Constantly?

Is your Concord HVAC running non-stop, even when your home already feels cool? It’s a common issue—especially during Concord’s hottest summer months—and one that can drive up your utility bills, put strain on your system, and shorten its lifespan if left unaddressed.

If your central AC won’t stop running, don’t panic. In many cases, it’s a solvable issue. Below, your experts from Chad Love Services will walk through the most common reasons your air conditioning system might be running constantly and what you can do about it.

Start With the Simple Fixes

Before assuming something’s broken, rule out the small stuff. Your AC could be running continuously due to:

• Open windows or exterior doors
• Incorrect thermostat settings (like fan mode set to “On” instead of “Auto”)
• The blower fan running independently of the cooling cycle

These issues are quick to fix and don’t require professional AC repair in Concord. Make sure your home is sealed up tight and check your thermostat mode and schedule settings.

The Most Common Concord AC Issues

1. Dirty or Clogged Air Filter

A clogged air filter is one of the most common causes of an AC system that won’t cycle off. When airflow is restricted, your system works harder and longer to push air through the filter and cool your home.

What to do: Turn off your AC and inspect the filter. If it looks dirty or clogged, replace it. Make sure you’re using the correct size and that it meets your manufacturer’s airflow specifications. This one step can restore cooling efficiency and may stop the system from running nonstop.

2. Airflow Problems

Blocked vents, closed dampers, or leaky ductwork can restrict airflow and prevent your system from cooling your home evenly. If air can’t circulate properly, your AC keeps running in an attempt to reach the thermostat setting.

What to do:

• Open and unblock all vents and returns
• Ensure no furniture or curtains are covering registers
• If possible, inspect ductwork for visible leaks, especially at joints

If you suspect deeper duct or blower issues, schedule an AC tune-up in Concord, NC to have a professional test your airflow and recommend solutions.

3. Thermostat Issues

If your thermostat is malfunctioning, it might signal the AC to keep running—even after your home has reached the set temperature. This is especially likely if the thermostat is old, placed near a heat source, or has incorrect programming.

What to do:

• Double-check your temperature settings and schedule
• Try resetting your digital thermostat
• Consider replacing it if it’s outdated or unresponsive

If the issue continues, a technician from Chad Love Services can help determine whether your thermostat or AC unit is to blame.

4. Dirty Evaporator Coil

A dirty evaporator coil can’t absorb heat efficiently, which causes your system to work overtime. If the coil is covered in dust or mold, or worse—frozen—it limits the system’s ability to cool the air, keeping the unit running longer than necessary.

What to do: Shut off the system and inspect the coil (usually located in the indoor air handler). If it’s dirty, schedule a professional AC maintenance service to have it safely cleaned. If the coil is frozen, switch the system to fan mode and allow it to thaw, then call for service.

5. Low or Leaking Refrigerant

Low refrigerant levels can lead to insufficient cooling, which makes the system run longer as it struggles to reach the thermostat setting. In many cases, this is due to a leak in the system, which requires professional repair.

What to do: Look for signs of trouble like ice buildup on the refrigerant lines or puddles near your outdoor unit. If you suspect a leak, contact us immediately for air conditioning repair in Concord. Refrigerant issues should never be ignored or refilled without finding the root cause.

6. AC Unit Is the Wrong Size

If your system was installed recently and runs far more often than your old unit did, it may be improperly sized. An undersized unit will run constantly in an effort to meet the load, while an oversized unit may cool the home too quickly, leading to uneven temperatures and frequent short cycling.

What to do: Have a professional perform a load calculation to ensure your unit is correctly sized for your home. If it’s not, it might be time to consider air conditioning installation in Concord with the proper system for your space, insulation levels, and lifestyle.

When Is It Normal for Your AC to Run Constantly?

There are times when a constantly running AC is completely normal—especially during extreme heat. If it’s 95 degrees outside and your system is keeping the home at 75, that’s actually a sign it’s doing its job. Long run times during peak heat are typical, especially in homes with older windows or less insulation.

But if your system never shuts off at night, or if it’s running non-stop on milder days, something is likely wrong. If you’re in need of a repair, or even an AC replacement in Concord, connect with our experts!
