This simple step can help restore airflow and cooling performancels warm. If your AC is on but not cooling, it could be due to a number of simple or more serious issues. Here are a few things homeowners can check themselves before calling in the professionals for AC repair in Springfield, VA—and why it’s important to act quickly to avoid further damage to your system.
Why is my air conditioner running but not cooling?
If your air conditioner is running but not cooling, common causes include a clogged air filter, dirty outdoor condenser, blocked or dirty evaporator coil, or incorrect thermostat settings. These issues restrict airflow or prevent proper heat exchange and can often be resolved with basic maintenance or a quick AC repair
Check and Clean Your Air Filter
A dirty or clogged air filter is one of the most common causes of weak cooling performance. When your AC can’t draw in enough air due to a blocked filter, it struggles to cool your home effectively—and the added strain can even lead to bigger problems like frozen coils. Check your air filter and, if it looks dirty, replace it with a new one. Ideally, filters should be changed every 1-3 months, depending on usage, pets, and local air quality.
Inspect the Outdoor Unit
Your AC’s outdoor condenser unit plays a key role in releasing the heat your system removes from your home. If the unit is clogged with dirt, leaves, or grass clippings—or surrounded by overgrown vegetation—it can’t do its job properly. Take a few minutes to gently rinse the unit with a garden hose (avoid high pressure), and trim back any plants to allow at least two feet of clearance around it. This simple step can help restore airflow and cooling performance. If issues persist even after cleaning, it might be time to evaluate whether your home needs a new AC.
Clean the Indoor Coils
Your AC’s evaporator coils, located inside the air handler, can also collect dust over time. Dirty coils limit the system’s ability to absorb heat from your home, leading to poor cooling results. While it’s best to have a professional handle in-depth coil cleaning during your system’s routine maintenance visit, you can gently dust accessible areas and ensure the surrounding space is clean and unobstructed.
Double-Check Your Thermostat
It may seem obvious, but don’t overlook your thermostat settings. Make sure it’s set to “Cool” and that the temperature is lower than your current room temperature. Also check if the fan is set to “Auto” rather than “On.” In the “On” setting, the fan runs continuously, even when the AC isn’t actively cooling, which can make it seem like the system is working without lowering the temperature.
Still Not Cooling? Time for Professional AC Repair
If you’ve gone through the checklist above and your air conditioner is still running but not cooling, it’s time to call in the experts. The issue could involve low refrigerant levels, a failing compressor, electrical problems, or ductwork issues—all of which require professional tools and training to diagnose and repair safely. Even if the issue seems minor, catching it early with a seasonal air conditioner tune-up service can help you avoid bigger repairs later.
Prompt repair is essential to prevent further damage and to restore your home’s comfort as quickly as possible. Delaying service can lead to higher energy bills, worsening problems, and more expensive repairs down the line.

Question: What are the most common DIY steps I can take when my AC runs but doesn’t cool?
Answer: Start by checking and replacing a dirty air filter, as it restricts airflow and reduces cooling. Clean the outdoor condenser unit by removing debris and trimming vegetation. Also, make sure your thermostat is set to “Cool” and the fan is set to “Auto.”
Question: Why might cleaning the coils help when the AC is running but not cooling?
Answer: Dirty evaporator or condenser coils can limit heat exchange, making the system less effective at cooling. Light dusting may help, but professional cleaning is often necessary to restore full efficiency and prevent long-term damage.
Question: When should I stop DIY fixes and call an HVAC technician?
Answer: If cleaning filters and coils doesn’t solve the issue, call a technician. Problems like refrigerant leaks, compressor issues, electrical faults, or duct leaks usually require professional tools and knowledge to diagnose and repair safely.
Question: Could duct or system sizing issues contribute to cooling problems?
Answer: Yes. Leaky ducts can let cool air escape, reducing efficiency. If your AC is too small, it may not cool effectively. If it’s too large, it may cycle too quickly without properly removing humidity, both of which impact comfort.
Question: Why is regular maintenance so important for my AC?
Answer: Routine maintenance like replacing filters, cleaning coils, and checking the system helps prevent breakdowns, improves energy efficiency, and extends the life of your AC unit. It also helps avoid costly emergency repairs down the road.
