What To Do When Air Conditioning Isn’t Cooling

During these hot Idaho summers, your home’s air conditioner might just be your favorite part of your home. So when the temperature rises and your air conditioning isn’t cooling your home, you’ll want to fix it as soon as possible. But where do you start?

Follow along as we go through the steps and items you should check when your air conditioner isn’t cooling.

Step One: Check Your Thermostat Settings

Your thermostat isn’t always set correctly. At times, it’s just hot enough that your A/C’s current setting won’t cool your home enough to beat the heat. Occasionally, someone in your home turned your thermostat off without saying anything.

So once you realize that your air conditioner isn’t working, the first item to check is your thermostat setting. Make sure that your thermostat is set to the proper settings. Check to see that your thermostat is set to AUTO, not ON. If your thermostat is only set to “ON”, your blower fans will run constantly regardless of if there’s cool airflow or not. If you change your thermostat settings to AUTO, the fans will run when there’s cool airflow.

Then, check on your thermostat to see if your A/C is set to COOL, not HEAT.

Step Two: Check Your Filter

Most air conditioners require a filter. This filter plays a critical role in your air conditioner’s ability to function. The filter stops small airborne particulates like dust, smoke, pet dander, pollen, bacteria, lint, and more from circulating around your home. The filter also blocks them from reaching the mechanical components of your air conditioner. Over time, this can cause a thick layer of build-up on your filter that makes it difficult for air to get through at all to the mechanical components. A lack of airflow could stop your air conditioner from cooling. It can even shut it down altogether in dire cases. This makes regular cooling system maintenance a must.

Therefore, if your air conditioner isn’t cooling, it might be the result of a dirty filter. Remove your filter and check that it’s clean. If there is a layer of dust, dander, pollen, etc., try changing the filter and see if that helps. If it’s clean or if changing the filter doesn’t help, you should move onto step 3.

Step Three: Call a Professional

While DIY troubleshooting can solve many problems, there are some situations where you should leave diagnostics and repairs to the professionals. When your air conditioning isn’t cooling your home and you’ve checked the thermostat and filter, you should call a trusted professional.

Calling a professional can pay off substantially. Here are a few reasons why:

Saves you from trial and error

Let’s say you don’t stop at the air filter and dive into the mechanical parts. You try replacing the heat pump, the coils, the condenser unit. . .  And suddenly you have a ton of air conditioning parts, an air conditioner that doesn’t work, and no surefire solution in sight. A professional HVAC technician will be able to diagnose and repair the issue without the costly guess and check.

Warranty Compliance

If you bought a warranty from the manufacturer, sometimes it will require you to seek help from a licensed HVAC professional. DIY-repairs could void your warranty and leave you on the hook for replacing your HVAC unit.

Speed And Convenience Of Hiring A Pro

Your HVAC technician does several repairs a day and over the years, their experience adds up. They will be able to quickly diagnose the problem, repair or replace any damaged components, and make your home into a cool, comfortable oasis again.

When you call an HVAC company for repairs, tell them the manufacturer details about your HVAC unit and when it stopped working. They’ll send a professional to your home to diagnose and repair the problem. While there, they will also examine your air conditioner and tell you if there are other components that might break down soon.
