Fall may be here, but there are still a few warms days left in the season. If your air conditioner has decided to malfunction, you might be left out in the heat. The last thing you want to do is spend the last warm days of the year sweating in your home. Luckily, you don't have to. Here are some simple steps you can take if your air conditioner has stopped blowing cold air.
Change the Filter
This might seem like an over-simplified solution, but a dirty filter can wreak havoc on your air conditioner. When your filter is clogged, it can prevent fresh air from flowing through to your air conditioning unit. When that happens, you'll notice a decrease in the amount of air that blows through your vents. If you're not getting enough cold air through the vents, change the air filter. While you have the filter compartment open, use your vacuum to remove the dirt and dust that might have built up inside the compartment.
Check for Ice Deposits
If you've changed the filter and you still aren't getting cold air through the vents, take a look at the main air conditioning unit. Pay close attention to the copper pipes that lead from the unit to your home. If you see ice buildup on the pipes, you have one of two problems. First, your coils or fan could be dirty, which is causing a problem with airflow. Second, you might have low refrigerant levels. Turn you air conditioner on to fan for several minutes. If the ice melts, you need to clean your coils and fan. If it doesn't, you need to call your technician and have them replace your refrigerant.
Clean the Coils and Fan Blades
If your coils and fan blades are caked with dirt, you'll need to give them a thorough cleaning. You can take care of the cleaning process with your garden hose and a high-pressure nozzle. Attach the high-pressure nozzle to your garden hose. Turn the water on and spray the coils on your air conditioner. Continue spraying until the water draining from the bottom is clear. Once you've cleaned the coils, point your hose through the top of the air conditioning unit and spray the fan blades. Continue spraying until you can't see any more dirt.
If your air conditioner has decided to stop blowing cold air, use the simple steps provided above to get your unit working again. If you continue to have problems with your air conditioner, be sure to contact your air conditioning repair technician as soon as possible.
