3 Questions To Ask When Your Central Air Conditioner Is Not Cooling Properly

After returning home one day, you may discover that your air conditioner is not cooling your house properly. Before you call a service technician, ask yourself the following troubleshooting questions to see if there could be a simple cause to the problem with a possible easy solution.

Is The Condensation Drain Clogged Up?

Especially when the temperatures and humidity are high, your air conditioner unit will produce a lot of condensation. When it is running, it pulls air from the outside and removes the moisture before circulating it through your house. Normally, this extra moisture passes through the condensation drain and into the drip pan.

However, when there is excess moisture in the air, the extra water may become too much for the unit to handle. It can also combine with any dust or dirt inside the unit. When this happens, the result could clog up the drain, taking away the air conditioner's ability to circulate air properly when the water backs up into the system.

To check to see if the drain is clogged, turn off the unit. Then, remove the access panel and locate the drip pan at the bottom. Above the pan, you should see a small tube that is the condensation drain. Remove the hose clamp and look through it to see if there are any clogs.

If so, rinse the tube with hot water. Then, replace it and empty the drip pan. Put the access panel back on and start up the unit. After a couple of cycles, your home should start to feel cool again. If not, go on to the next question.

Are The Unit's Exterior Vents Blocked?

Examine the exterior vents of your air conditioning unit and check for anything that could be blocking them. This includes dust, debris, plants, or a wayward plastic grocery bag that got stuck to the side.

Whenever the exterior vents are blocked, the unit is unable to pull air into the compressor. When this happens, the compressor and motor could overheat. As a result, they may not work efficiently, making them unable to cool your home. Plus, the added heat can also affect the temperature of the air.

If you see an obstacle blocking the vents, remove it. Also, trim back any plants that have grown so close to the unit that the leaves are being sucked into the vents.

If the blockage is caused by dirt, turn off the unit. In a gallon bucket, mix together a couple of teaspoons of mild dish detergent with a half gallon of hot water. Use a soft scrub brush to clean the vents out. Then, wipe them dry with a clean rag.

After doing the above, turn the system back on to see if there is any improvement. If not, go on to the next question.

Is The Refrigerant Level Correct?

After you have eliminated the above causes, the last thing to ask yourself is if your refrigerant's level correct. If there is either too much or too little in the system, it will not cool your home properly.

While you can check the level yourself, you should have a certified repair technician fill it for you. Not only does this prevent the possibility of under or overcharging the unit, but it decreases the chances that any will leak out into the environment.

Once you have gone through the above questions, you may not know what the trouble is or find out the problem is too much for you to fix yourself. Either way, you may want to contact a professional who specializes in air conditioning repair. They can diagnose the problem and offer you possible solutions, based on what they find during an inspection of your unit.
