There’s nothing quite like escaping the harsh summer heat and stepping into a cool, refreshing room. But what happens when your AC decides to stop working properly? Instead of blowing out cool air, it’s blowing out hot air!

Now you’re stuck in a sweltering room, wondering what went wrong. Don’t worry, this guide will help you troubleshoot some common reasons why your AC might not be cooling your space effectively, and how to fix them.

The Dirty Air Filter- It Can Be A Problem

Your AC is just like a car. As your car needs a clean air filter to run smoothly, so does your AC. A dirty air filter is one of the most frequent reasons an AC causes troubles. The filter traps dust and dirt from the air. But over time, it can become clogged, blocking the flow of cool air. This makes your AC work harder, reducing its efficiency and cooling capacity.

Fixing the Filter Problem:

Cleaning the air filter is easy! Most filters can be cleaned every 2-3 months. Here’s how to do it:

  1. Turn off the AC and disconnect it from the power source. Safety first!
  2. Locate the air filter. It’s usually found behind a panel on the front of your AC unit. Consult your user manual if you’re unsure.
  3. Remove the filter. There might be multiple filters, so take them out one by one.
  4. Clean the filter with a soft brush or vacuum cleaner. Gently remove any dust and debris. Be careful not to bend the filter.
  5. If the filter is really dirty, wash it with warm water and a mild detergent. Let it dry completely before putting it back.
  6. Reinstall the clean filter(s) and close the panel.

Is There a Leak in the Coolant System?

Your AC uses a special coolant, like refrigerant, to absorb heat from the air and create cool air. If the refrigerant level is low or there’s a leak in the system, your AC won’t be able to cool your room effectively.

Signs of a Refrigerant Leak or Low Level:

  • Hissing or bubbling sounds coming from your AC when you turn it on.
  • Ice forming on the outdoor unit.
  • The AC is blowing lukewarm air.

Not a DIY Fix:

If you suspect a refrigerant leak, it’s best to call a professional HVAC repair service.  Refrigerants can be harmful if not handled properly. A technician has the expertise and tools to examine and fix the leak or recharge the refrigerant level.

The Main Component of the AC: The Compressor

The compressor is the powerhouse of your AC. It pressurizes the refrigerant, allowing it to circulate through the system and absorb heat. If the compressor does not work properly, your AC won’t be able to cool your space properly.

Signs of a Compressor Problem:

  • The AC is blowing hot air.
  • The outdoor unit shakes or makes loud noises when you turn on the AC.
  • The AC doesn’t turn on at all.

Call Professional AC Repair Company

A damaged compressor is a serious issue. It can be expensive to repair. If you suspect a compressor problem, consult an AC technician to diagnose the issue and recommend the best course of action.

Double-Check the Thermostat Setting

Before you dive into troubleshooting more complex issues, take a moment to check your thermostat setting. It might be a simple fix!

What is a Thermostat?

Your thermostat is the control center of your AC system. It allows you to set the desired temperature for your space.

Fixing the Thermostat Setting:

  • Make sure the thermostat is set to “cool” mode.
  • Ensure the set temperature is lower than the current room temperature.
  • Check if the thermostat is set to “auto” mode instead of “on” mode. In auto mode, the AC will automatically turn on and off to maintain the desired temperature.

Regular Maintenance is Important!

Just like any other appliance, your AC needs regular maintenance to function at its best. Ideally, you should get your AC serviced by a professional AC repair service every 2-3 months, especially before the peak summer season. This will help identify and address minor issues before they turn into major problems.
