Check the Power Supply

When your air conditioner stops operating, one of the first things to check is the power source. A tripped breaker or blown fuse can cause your air conditioner to cease working. Before contacting HVAC professionals, ensure that your AC unit is receiving power.

First, check the circuit breaker or fuse box to ensure that the breaker for the AC unit has not tripped or the fuse has not blown. Reset the breaker if the fuse has blown or the breaker has tripped. You may also replace the fuse. Check the power cord to confirm it is plugged in and properly linked to the socket.

If the problem persists, try shutting off the AC unit on the thermostat and then turning it back on after a few minutes. This can occasionally be used to reset the equipment and resolve the problem.

Check the Thermostat

If your air conditioner isn’t operating properly, the thermostat could be to blame. The thermostat is the control center of your air conditioner, and if it isn’t working, your air conditioner won’t either.

Begin by double-checking the thermostat settings. Check that the thermostat is set to “cool” and that the temperature is set lower than the current room temperature. If the thermostat is set, you should hear the air conditioner start on soon after altering the temperature.

Check the thermostat batteries next. If the thermostat’s battery is low, it may not work properly. Replace the batteries to see if that resolves the issue. If you have a programmable thermostat, double-check the settings. Incorrect settings or programming might sometimes cause the AC unit to not switch on or off as planned.

Clean or Replace the Air Filter

A filthy or clogged air filter might cause your air conditioner to malfunction. The air filter is in charge of keeping your home’s air pure and free of debris. But when it becomes dirty or clogged, it can impede airflow to your AC unit, causing it to work harder and stop working.

The good news is that replacing or cleaning your air filter is a simple fix. Begin by identifying your air conditioner’s air filter. It is typically found in the air handler unit, which is positioned in the attic, basement, or closet.

Remove the filthy or clogged air filter from the air handler unit and replace it with a fresh one. A replacement air filter is available at your local hardware store. If the air filter isn’t too filthy, you can vacuum it or wash it with soap and water. Before reinstalling the air filter, make sure it has completely dried.

Check the Air Ducts

The air ducts are in charge of distributing cool air throughout your home. If your air ducts are clogged, it might reduce airflow and cause your AC unit to malfunction.

Begin by looking for apparent indicators of damage, such as cracks or holes, in your air ducts. If you see any damage, it is critical that it be repaired by HVAC maintenance professionals. Damaged air ducts can cause air leaks, lowering the efficiency of your AC unit and increasing your energy expenses.

Next, inspect your air ducts for any obstructions. Over time, dust, dirt, and other items can accumulate in your air ducts and obstruct airflow. Remove the air vent cover and use a vacuum or brush to remove any debris from the air ducts. Finally, look for any disconnected or loose pieces of air ducts. If you locate any, reattach them or secure them with duct tape.

Inspect the Outdoor Unit

The outdoor unit is in charge of taking heat from your home and sending it outside. If there is a problem with your outside unit, it can influence the functioning of your AC unit.

Begin by evaluating the exterior unit for noticeable damage, such as dents or rust. Any damage to the outside unit can reduce its efficiency and cause it to malfunction. If you see any damage, contact a local HVAC maintenance and repair company to have it repaired or replaced.

Next, inspect the surrounding area for impediments, such as plants or rubbish. The outside unit needs adequate airflow to function properly, so keep the space around it clear. Remove any impediments and prune any plants or shrubs that may be obstructing ventilation.

Finally, inspect the coils of the outdoor unit for any dirt or debris buildup. Dirt and debris can accumulate in the coils over time, diminishing their effectiveness and forcing your AC unit to work harder. Clean the coils with a gentle brush or spray water to remove any dirt or debris.

Check for Refrigerant Leaks

The material that cools the air in your AC system is known as refrigerant. A refrigerant leak can diminish cooling capacity and force your air conditioner to work harder than it should. This potentially leads to more significant problems down the road.

Since refrigerants are hazardous substances, they should only be checked for leaks by a licensed HVAC expert. They have the appropriate tools to test for leaks and correct any problems. In general, it’s recommended to schedule regular maintenance with an HVAC maintenance business. So they can spot any potential problems before they become bigger ones.

If you suspect a refrigerant leak, switch off your air conditioner and contact a professional HVAC expert immediately. They will be able to diagnose and repair the problem, keeping your AC system functioning properly and keeping your home cool and pleasant.
