Having your air conditioner break down would be considered a bad day for anyone, but having your air conditioner break down on one of the hottest days of the summer would be considered a really bad day. You just know that you will be hot and sweaty for some time before you can get your air conditioner operational again. You may not be able to 100% prevent your air conditioner from breaking down, but by understanding the most common reasons it may break down gives you the opportunity to spot an issue early and schedule an air conditioner repair before it worsens or perhaps troubleshoot an issue, if one arises.

5 Causes of Air Conditioner Problems

Here are 5 reasons your air conditioner may have issues:

1. Dirty Condenser Coils

Condenser coils are a component of your air conditioner’s outdoor unit. The coils help remove and transfer heat from the air in your home to the exterior of your home. When the coils become dirty and covered with grime, their performance is reduced significantly, and heat will not be appropriately transferred, making the unit work harder to cool down your home. This results in excessive wear and tear on your unit which eventually leads to failure.

2. Frozen Evaporator Coils

Your air conditioning unit’s evaporator coils contain refrigerant which absorbs heat from the air. These coils require warm air to function effectively, unfortunately, at times the evaporator coils can freeze and warm air will enter your home instead of cooled air.

3. Thermostat Issues

When the thermostat is not correctly calibrated or faulty, your air conditioner will not be notified or instructed to run at the appropriate temperature. As a result, your air conditioner will not function properly. Although this is not a serious issue, and can be corrected by installing a new thermostat, it will affect the performance of your air conditioner if left unchecked. Contact an experienced HVAC professional to replace or calibrate your thermostat correctly.

4. Clogged Drain Lines

The moisture drawn from the air is removed through the drain line into a pan, and eventually down a drain. If the drain line or pan gets clogged the water will inevitably back up into the unit and damage it. If this is missed or ignored, the water may seep into the walls, ceilings, and furnishings, creating the potential for water damage and mold growth in your home.

5. Fan Issues

Your air conditioner unit has two fans, one inside your home also known as the blower which ‘blows’ cool air into your home. The second fan is located outside of your home and forces air over the outdoor unit to dispel heat outside the house. If either of these fans are not working properly, it can lead to poor airflow in the home, and the compressor unit itself may break down due to high pressure or high heat.
