Why Is My Central Air Conditioner Blowing Hot Air?

When it comes to home repair issues, few will get you sweating as much as your central air conditioner blowing hot air during the summer. Don’t you agree? While frustrating, there is no need to panic. Yes, there are some complicated issues that can cause the problem, but you don’t need to call a professional just yet. Today’s article shares a few troubleshooting tips that you can try first. Afterward, if your central air conditioner is still blowing hot air, you will need to contact a repair technician.

1. Check Your Thermostat and Fan Setting – This may sound weird, but it happens. Make sure that your thermostat is not set to “heat” or “off”. It is not uncommon for these settings to get accidentally switched, especially if you have children who like to touch things. The correct setting should have your thermostat set to “cool” and the fan set to “auto”.

2. The Outside Until Is Clogged – Your outside and inside units work in unison to remove heat from your home. A buildup of leaves, dirt, and other debris around the outside unit can cause a problem. Simply remove or sweep away and visible junk around the outside unit. Also, trim any close hedges and cut tall grass.

3. You Lost Power to the Outside Unit – As stated above, your central air has two units. So, it is possible for the outside unit to lose power while the inside unit continues to run, which will blow warm or hot air. Start by checking the breaker box if the circuit tripped. If that is not the case, check to see if the emergency switch is off.

Today’s blog posts provided a few easy troubleshooting tips if your central air conditioner is blowing hot air. Nevertheless, there are times when you will need professional help. These issues include a refrigerant leak, dirty evaporator coil, and leaking or damaged ductwork. You should never attempt to fix these problems yourself.
