My AC Is Running But My House Isn’t Cooling Down

There are a variety of reasons your AC unit isn’t effectively cooling your home. Some have a simple fix you can handle independently, while others require help from a local HVAC professional. If you’re unsure, use this guide to get your home cool and comfy again.

AC Troubleshooting Steps for Northeast Ohio Homeowners

Check the Thermostat

If your AC is set to “On” instead of “Auto,” the fan for your air conditioner will run at all times, even when the air isn’t being cooled. If you’re noticing warm air coming from your vents, change your thermostat to “Auto.”

Change the Air Filter

When your air filter is dirty, it can stop airflow, which is a nightmare for your AC (and for your hopes of enjoying a cool indoor Fourth of July)! A dirty air filter won’t just keep your air conditioner from cooling but can also cause elements to freeze, leading to more trouble later. If your AC unit struggles to get your home to the desired temperature, check your air filter and change it if it is dirty.

Clean the Outside Unit

Dirt and debris can easily pile up on or near the outside unit of your AC (known as the “condenser”). The condenser cannot properly remove the heat from your home when it’s too dirty or crowded. Remove any lawn clippings, weeds, or leaves from the unit and the area surrounding it. If you notice some dirt buildup on top, you can also give it a gentle spray with the garden hose.

When to Call in the AC Professionals

If none of the steps above seem to work, it’s time to call a reputable AC contractor. Here are some of the most common air conditioning problems that would prevent your home from cooling properly:

Broken or Faulty Condenser Fan Motor

No matter how perfectly you clean your air conditioner’s outside unit, the entire AC system won’t function if its fan isn’t working.

Low or Leaking Refrigerant

Your AC needs refrigerant to absorb heat from the air. Low refrigerant levels are worse than just failing to cool your home – leaving your air conditioner running without enough refrigerant could damage the system beyond repair. Turn off your AC right away and call a professional if you notice any of these signs:

  • There is ice buildup on the refrigerant line and the outside unit.
  • You hear a noise that sounds like hissing or bubbling.
  • The AC works just fine on cool days and at night but struggles on particularly hot days.

Problems With the Compressor

Your compressor plays an integral role in your air conditioning system and sits within the condenser outside your home. If it’s damaged, you may notice spikes in your energy bill, odd sounds, or even a tripped circuit breaker. Only a trained HVAC professional should diagnose and solve problems with your AC’s compressor.
