Your air conditioner has exactly one job: to cool your home. If you wake up on a hot, muggy summer morning, you don’t have to call an HVAC technician immediately. Instead, you can attempt to fix your AC yourself first.
The video covers the most important elements of DIY AC repair for any unit that stops blowing cold air. One of the first steps the host recommends is checking your breaker panel and anything else in your electrical system that might stop your AC from working.
If the problem isn’t something wrong in your AC unit, an HVAC repair technician won’t be able to help you.
Once you discover that the problem is likely with the AC unit, you can move on to troubleshooting it specifically. Check your thermostat first to make sure the AC unit is set to cool. If that’s set correctly, then you can check the AC compressor outside your house.
Try using a screwdriver to manually turn the fan on. To make sure your AC continues to work, you will need support from an HVAC contractor to fix the internal components of the AC unit.
