Top 5 Reasons Why Your Air Conditioner Is Running but Not Blowing Cold Air
Hey there, Colorado Springs! If your air conditioner is acting up and not blowing cold air, you’re not alone. We know how frustrating it can be to come home to a hot house, especially when the summer heat is blazing. But don’t sweat it—we at Interstate 25 Mechanical are here to help you troubleshoot and solve the problem. Let’s dive into some common issues and their solutions to get your AC back on track!
How Does a Central AC System Work?
Before we jump into the nitty-gritty, it helps to understand how your central AC system works. Your air conditioner uses a liquid refrigerant that flows over the indoor evaporator coils to absorb heat from your home. This turns the refrigerant into a gas, which then travels to the outdoor condensing unit, releasing the heat outside and turning back into a liquid. This cycle repeats to keep your home cool. With so many steps, there’s plenty of room for things to go wrong.

Leaking or Low Refrigerant
What Causes Refrigerant Leaks?
Refrigerant leaks are often caused by wear and tear, corrosion, or poor installation. These leaks can prevent your AC from cooling properly.
Signs of Low Refrigerant
- Your AC isn’t blowing cold air.
- You hear a hissing sound near your AC unit.
- There’s ice on your evaporator coils.
- Your home feels more humid than usual.
How to Fix Refrigerant Issues
If you suspect a refrigerant leak, it’s time to call in the pros. Handling refrigerant requires special certification, and we at Interstate 25 Mechanical are equipped to diagnose and fix these issues safely.

Dirty or Clogged Filters
Importance of Clean Filters
Filters trap dust, pollen, and other debris to keep your air clean. But when they get clogged, they can restrict airflow and make your AC work harder than it should.
How to Check and Replace Filters
Check your filters monthly, especially during heavy use. If they’re dirty, replace them. It’s a simple fix that can make a big difference.
Preventing Filter Issues
Change your filters every three months, or more often if you have pets or allergies. This keeps your system running smoothly and your air clean.

Problems with the Evaporator Coil or Condenser
Common Issues with Evaporator Coils
Evaporator coils can freeze up if there’s a refrigerant issue or if the filters are dirty, leading to poor cooling performance.
Signs of Condenser Problems
- The AC runs but doesn’t cool.
- You hear strange noises from the outdoor unit.
- The unit cycles on and off frequently.
Maintenance Tips for Coils and Condensers
Regular maintenance, including cleaning the coils and checking the refrigerant levels, can prevent these issues. If you notice any of these signs, give us a call.
-
Blocked or Clogged Registers
Identifying Blocked Registers
Blocked registers can restrict airflow and make certain rooms warmer than others. Check to ensure all vents are open and unobstructed.
How to Clear Blockages
Clear any furniture or objects blocking the vents. If you suspect a blockage in the ductwork, it might be time for a professional inspection.
Preventing Ventilation Problems
Regularly check your vents and keep them open and clean to ensure optimal airflow throughout your home.

Thermostat Issues
Common Thermostat Problems
Sometimes, the issue isn’t with your AC unit but with the thermostat. It might be set incorrectly, or it could be malfunctioning.
How to Troubleshoot Thermostat Issues
Make sure your thermostat is set to “cool” and the temperature is set lower than the current room temperature. If it runs on batteries, try replacing them.
When to Call a Professional
If your thermostat still isn’t working correctly, it might be time for a replacement. Call us now and we can help you choose and install a new thermostat that works for you.
Other Common AC Function Issues
AC Not Cooling Enough : This can be due to various reasons, from dirty filters to refrigerant leaks or even an improperly sized unit. Regular maintenance and inspections can keep your system running efficiently.
AC Leaking Water Inside : This often indicates a clogged condensate drain line. Turn off your AC and call a professional to clear the blockage and prevent water damage.
AC Leaking Water Outside : A small puddle under your condenser unit is normal on hot days. But if it’s excessive, you might have a refrigerant issue or a blocked drain pipe.
AC Running Constantly : If your AC never seems to stop running, check for dirty filters or issues with the thermostat. It might also indicate that your unit is too small for your home.
AC Fan Issues : If the indoor or outdoor fan isn’t working, check the breaker and ensure there are no blockages. If the fan still doesn’t work, you may need a new motor or capacitor.
