Common AC Problems and How to Fix Them 2

Frozen Evaporator Coil

If you notice that your AC unit is not cooling as effectively as it used to, a possible cause is a frozen evaporator coil. One sign of a frozen coil is frost or ice buildup on the indoor unit. To fix this problem, turn off the AC unit and let the ice melt completely before turning it back on. If this issue continues to happen, it could be due to restricted airflow or low refrigerant levels

Dirty Air Filter

Another common issue that can cause your AC unit to malfunction is a dirty air filter. Over time, your air filter can become clogged with dust, debris, and other pollutants, which can lead to poor airflow and decreased efficiency for your unit. To avoid this, replace your air filter every 1-3 months, depending on the amount of use your AC unit gets. This can also help to improve indoor air quality in your home.

Low Refrigerant Levels

If the levels of refrigerant in your AC unit are too low, it can cause your indoor space to feel warm, even when the unit is on. There could be a leak in the system causing the refrigerant to escape. This is not a problem that can easily be fixed without the assistance of an HVAC technician. It’s best to have regular maintenance performed on your AC system to avoid any costly repairs or replacements.

Thermostat Issues

The thermostat is the temperature control center for your AC unit. If there are any issues with the thermostat, your AC unit may not be working as efficiently. One common issue is a faulty or outdated thermostat. Over time, these devices can deteriorate and lose their accuracy. If this seems to be the problem, you can try replacing your thermostat with a newer model.

Clogged Drain Line

The drain line is responsible for carrying out the excess moisture that your AC unit removes from the air in your home. But, over time, mold and algae can grow inside the drain line and clog it up. This can cause water leaks or backups, which can damage your AC unit and cause your indoor air quality to deteriorate. If you notice any standing water near your AC unit, you may want to contact an HVAC technician to inspect and fix the drain line. Learn even more about AC Repair in this external resource.


There are many issues that can occur with your AC unit, and knowing what to look out for can save you money, time, and frustration. Regular maintenance, such as cleaning or replacing air filters, can help prevent many issues from happening. However, if you’re noticing any significant changes in your AC unit’s performance or any signs of malfunction, it’s best to contact an HVAC technician to diagnose and fix the issue.
