How to Fix a Broken Air Conditioner
Let me be the first to point it out: too hot . With many areas of the country suffering from extreme heat warnings, it’s important to make sure your air conditioner is running at peak efficiency . This assumes, of course, that you have already taken steps to ensure that your AC unit is ready to go all summer long. In the end, a scorcher awaits us.
When you’re already dealing with the heat, the last thing you want is frustration with a failed AC unit. Sometimes your air conditioner turns on and your thermostat is set to the desired temperature, but you still don’t feel like the device is actually cooling your house. Although many AC unit problems require the help of a professional, there is a good chance that you can successfully solve the problem on your own. Here’s what to do if your AC unit turns on but can’t cool your home effectively.
Clean or replace filter
An old or dirty air filter can prevent your air conditioner from delivering cold air properly. To check if the filter needs to be flushed or replaced, remove the filter and see if you can see through it. If all you see is a pile of dust and pet hair, it’s time for a change.
Check if the ventilation holes are blocked
Dirt or dust can also accumulate in the air vents and block the device’s airflow. Wiping them down is a quick fix to get the cool air out. While it may seem obvious, you should also make sure that your AC unit is placed so that no furniture or hard objects block the airflow right behind the vents.
Note: When adjusting the vents, you want all the air to blow downward during the hot summer months. (In winter, you want to pull the air up.)
Clean the area around the outdoor unit
Another reason your system may not be cooling is due to a clogged air condenser. Go outside and clean the outdoor unit, removing any debris that may be blocking air circulation. You may need to cut back bushes and pull out weeds that have grown around the machine. Aim to leave about 24 inches of space around the device to allow proper airflow.
When to Call a HVAC Professional
If you’ve done your best and your AC unit is still not cooling your home, you may need to invest in a professional or a brand new unit. According to USA Today , the main sign that it’s time to call a technician is icing on the outdoor unit. You may have a prime problem or a frozen evaporator coil; turn off the device and call an HVAC specialist.
There’s also the possibility that your current air conditioner isn’t powerful enough for your home in this heat. You may need a larger AC system to bring the temperature down to your desired temperature. In the meantime, here are our tips for staying safe during the heatwave .
