In the depths of summer, you can’t afford to have an air conditioning system on the fritz. While many issues require professional maintenance and repair, or specialized replacement parts, there’s a lot of troubleshooting you can do yourself with a little bit of knowledge and a little bit of elbow grease. Read ahead to learn how to fix common AC problems yourself.


1. Unit isn’t pushing cold air

If the air coming out of your vents doesn’t seem cool enough, there are a few things that might be wrong. As a first step, try setting the thermostat five degrees cooler. If that doesn’t work, you may have a dirty condenser. To resolve this, clean the condenser coil and the condenser fins. A common problem is a blocked condenser, which can be resolved by removing debris from under and around the outdoor AC unit, including trimming grass or weeds that have grown up around the unit. If you’ve tried all of these troubleshooting techniques and the unit still blows warm air, you may need to call a professional to replace your condenser or add refrigerant to the system.

2. Condenser doesn’t activate

If the condenser on your unit isn’t running, check for blown fuses or tripped circuit breakers. If all fuses and circuits check out, try setting your thermostat five degrees lower. If the condenser is still not running, contact an Air Conditioning professional.


3. Uneven Cooling

If your AC system is cooling the rooms of your house unevenly, try balancing the distribution by reducing the flow to rooms near the front of the system using the adjustments on the vents, this may allow more cool air to reach the back of the system.

4. The AC doesn’t cool your home enough

As with many AC problems, first try setting your thermostat lower. If this doesn’t do the trick, your AC unit may be too small for your home.

5. Condenser repeatedly clicks on and off

This means your condenser may be dirty or blocked. Try cleaning the condenser and/or removing debris from under and around the outdoor unit. This issue may also indicate that your evaporator is dirty. Follow this guide to cleaning the evaporator yourself.
