The sudden failure of your air conditioner can be alarming, or it can be something as simple as a blown fuse.

Many Split Ac not cooling problems require a professional technician to repair, but sometimes a homeowner can fix simple problems by troubleshooting them.

To help you troubleshoot four of your air conditioner's most common problems, we've put together this guide.

Many common problems with air conditioners can be caused by inadequate maintenance, so we recommend that you put your heating and cooling systems on an annual maintenance plan to help prevent future problems.

1. You can't turn on your air conditioner

You should first check your air conditioner outside to see if the condenser is running. Make sure your thermostat is set correctly and your unit is plugged in.

Make sure that your thermostat is set to cool and lower your thermostat 5 to 10 degrees to see if that fixes your problem. Several thermostats are tricky, so homeowners may be able to save time and money by reading their manual, according to John, our Maintenance Manager.

Check if a fuse has blown or a circuit breaker has tripped.

You will need to contact a professional to repair your air conditioner if it still won't turn on or your coil is frozen.

2. You can't get your air conditioner to cool

When your air conditioner turns on but does not cool, you may have a dirty or blocked air condenser. If you find debris or weeds blocking air flow, you should clean around the outside unit and remove them.

Make sure your filter is clean next. If the filter is dirty, it can restrict air from reaching the evaporator coil, causing it to freeze. If you have pets or run your air conditioner often, you may need to change it more often. To test your filter, pull it out and see if you can see through it.

You will need to contact a professional if your air conditioner is still not cooling air due to a problem with your compressor or refrigerant.

3. The air conditioner in your home isn't cooling your house adequately

Your air conditioner may not be sized appropriately if it is on and set properly but is still not cooling your home to your standards.

You should ensure that your system is sized so that it keeps your home cool on an average summer day. On average, a system should be able to maintain a temperature difference between the outdoor and indoor temperatures of 20-25 degrees. When it's 95 degrees outside, your air conditioner isn't designed to keep your home at 68 degrees.

If you can't keep up with your air conditioner on a normal summer day, you may have a problem with the charge or a frozen evaporator coil. If you see ice on your outdoor unit, shut it off.
