Top 5 Air Conditioner Problems

Don’t get stuck in the heat! Listen to your AC unit’s warning signs. Let’s discuss the most common air conditioning problems as well as the unusual sounds a faulty system may make.

1. Clogged Drains

Ever wonder what happens to the moisture that your unit collects? It collects in a drain pan. If your cooling system doesn’t receive regular maintenance, this pan will overflow or become clogged. An overflowing or clogged drain can cause water leaks and damage ceilings, furniture, and appliances.

2. Fan Issues

Your fan can become inoperable due to damaged belts or motors. When this happens, airflow will be nonexistent, and during warmer months, your home will be unbearable. If your fan isn’t working, contact an HVAC technician to perform the necessary repairs or maintenance.

3. Contaminated Condenser Coils

Eventually, the AC coils outside your home will get coated with soot, grime, and other unpleasant contaminants that will impact the function and performance of your system. Our team of certified technicians has the necessary tools to remove excess dirt from your condenser coils to prevent your central air conditioner from overworking.

4. Malfunctioning Thermostat

If you have issues with your current AC thermostat, it may need to be recalibrated. Updated thermostats installed in older homes are sometimes set incorrectly, which impacts your air conditioning unit and causes it to operate inconsistently. Review your AC manual and ensure it’s set correctly.

5. Frozen Evaporator Coils

A correctly functioning evaporator coil will take heat from warm air in your home and distribute cool air with the help of a coolant. However, if your evaporators get too cold, ice will form on the coils and prevent warm air from being cooled.

3 Types of Air Conditioner Noises and Ways to Respond

An easy way to determine if your air conditioning unit needs repair is to listen to it. A malfunctioning system will inform you that something is wrong with a variety of noises. To help you determine what the sounds mean, we’ve listed the most common warning noises your air conditioning unit might make.

1. Grinding Sounds

If you hear metal grinding noises coming from your unit, there is likely a serious mechanical problem. This occurs when a system’s component is damaged and needs replacement or if a loose part needs tightening. If you hear grinding and continue to run your unit, additional damages may occur. You’re better off shutting down your system and waiting for a qualified technician to perform air conditioning repair.

2. Buzzing Noises

These sounds might be a little more difficult to hear when inside your house. If, however, your AC unit is running and you go outside your residence, listen for buzzing sounds. More often than not, buzzing noises will indicate an electrical issue that should be addressed as soon as possible. Ignoring an electrical problem could be dangerous.

3. Hissing Sounds

Continuous hissing or whistling sounds coming from your air conditioner are often a sign of a refrigerant leak. Hissing noises can also indicate a malfunctioning compressor or an internal valve leak. The best way to know the cause and solution of loud noises is to consult with a professional air conditioning technician.
