How to Know if Your AC is Having Problems

Summertime is a great time of year. The sun is shining, the birds are singing, and the air conditioner is blasting cold air into your home. But what happens when your AC stops working properly? How can you tell if there is something wrong with it? In this article, we will discuss some common signs that your AC may be having problems. We will also provide tips on how to get it fixed quickly and efficiently!


How to Check Whether Your Air Conditioner Is Running Properly

If you keep turning down your thermostat but don’t feel the house is cool, it’s time to have a look at your AC unit. It might be costly to repair your air conditioner, depending on the problem. However, if you can diagnose the problem yourself, you may be able to save some money.

Here are some steps to determine whether or not your AC unit is working properly to stay cool during the summer months. These steps will teach you how to identify if your air conditioner is operating and keep you cool and comfortable.


1. Examine Your Circuit Breaker

If your AC is having problems, one of the first things you should check is your circuit breaker. You may have overloaded the circuit if you have too many electronics plugged in and operating. This is particularly likely if you have a large number of fans going on a hot summer day. Check your fuse box to determine whether the circuit breaker is turned off and then turn it on. If everything else shuts down at the same time, you may be dealing with a power outage.


2. Monitor Your Thermostat

The first and most obvious sign that your AC is having issues is an abnormal reading on your thermostat. If your home is suddenly hotter than usual, your AC is likely the culprit.

Check to see if your thermostat batteries need to be replaced and if the settings have been changed. Look at your thermostat to find out whether it’s set to “auto” or “automatic.” If it is, this is why your AC keeps shutting off. The AC system will only turn on after the temperature rises above the figure printed on your thermostat when it’s set to auto. When you’re heating or cooling your home, it’s more efficient to leave the thermostat set to “auto.” If it isn’t warm or cold enough for you, please feel free to change the temperature.

  • Get peace of mind knowing your AC is running smoothly
  • Detect and diagnose issues with your AC unit
  • Get alerted when something goes wrong with your AC unit
  • Save money on energy bills by keeping your AC in good shape


3. Check Your Air Filter

Every 3 months or so, your filter should be replaced. You may need to replace it every month during the summer. If you have an issue with your air conditioner and haven’t replaced the filter in a while, start there. You don’t need to contact anyone if the situation resolves on its own.


4. Take a look at your blower

If you’re going to check your unit from the outside, leave it open and start looking. If the fan is on outdoors, you should be able to hear and see it. If there’s wind at the top of your unit and you detect air movement, then your blower is operating normally, so eliminate it as a possibility.


5. Inspect your Drainage System

Your air conditioner has a drainage system that gets rid of the water it collects while cooling your home. If this system is blocked, it can cause your AC unit to malfunction. Each month, you should inspect your unit’s drainage system to make sure it is clean and functioning properly.


6. Consider the climate

One of the first things you should think about when your AC isn’t working as it should is the climate. How hot is it outside? How humid is it? If the answer to either of those questions is “very,” then that could be part of the problem.

Your AC may not be able to keep up with demand on days when it’s extremely hot or humid and this can result in a less than ideal level of coolness inside your home. Another possibility is that your unit isn’t sized correctly for your home, which would also make it less effective on days when Mother Nature is cranking up the heat. Older units struggle to keep up when the temperature is higher outside. It’s possible that your unit is old or doesn’t have enough capacity to deal with the heat and size of your home. Because your equipment can’t operate at its maximum efficiency, it may be time for an upgrade.


  • Get the most out of your AC unit
  • Keep your home cool and comfortable on the hottest days
  • Make sure your AC is sized correctly for your home
  • Extend the life of your AC unit
