It’s the middle of summer and your air conditioner has just stopped working. You’re not sure what to do, so you start googling “AC Repair near me.” After reading a few articles, you realize that you might be able to fix it. Several potential causes come to mind, and you start troubleshooting. Unfortunately, after an hour of tinkering, you still can’t get the AC unit to work. It’s time to call in a professional. But before you do, there are a few things you should know. Here, we’ll discuss what to do if your air conditioner blows out warm air.
1. Check the Thermostat
The first thing you should do if your AC is blowing out warm air is to check the thermostat. The problem may lie with the thermostat and not the AC unit itself. If the thermostat is set to “heat” instead of “cool,” it will cause warm air to blow from the unit. You should also check to see if the thermostat is set to the correct temperature. If it’s set too low, the AC unit will run continuously without cooling the air.
2. Clean or Replace the Air Filter
If the air filter is clogged, it will restrict airflow and cause the AC unit to work harder than necessary. This can lead to several problems, including warm air blowing from the unit. To clean the air filter, simply remove it from the unit and wash it with soap and water. If it’s excessively dirty or damaged, you’ll need to replace it.
3. Check the Refrigerant Levels
If the refrigerant levels are low, it can cause warm air to blow from the unit. To check the levels, you’ll need a pressure gauge. You can usually find one at your local hardware store. Once you have the pressure gauge, attach it to the service valve and open it. The reading on the pressure gauge will tell you if the refrigerant levels are low. If they are, you’ll need to contact a professional to recharge the system.
4. Inspect the Evaporator Coils
If the evaporator coils are frozen, it will cause warm air to blow from the unit. To thaw the coils, simply turn off the AC unit and let it sit for a few hours. The coils will thaw on their own and your AC unit should be back to normal. Many people make the mistake of turning the unit back on too soon. This can cause extensive damage and you’ll likely need to replace the coils.
5. Check for Air Leaks
If there are air leaks in the ductwork, it will cause warm air to blow from the unit. To check for leaks, simply inspect the ductwork for any cracks or holes. If you find any, seal them with mastic or metal tape. These materials can be found at your local hardware store.
