Top 6 Common Air Conditioning Repair Issues and How to Fix Them

As summer comes back, a reliable air conditioner becomes a necessity. But just like any hard-working appliance, ACs can go wrong. You don’t always need to call a professional to fix something. Many AC issues can be solved with a little DIY troubleshooting and air conditioning repair.

This guide will teach you how to fix the top 10 air conditioning repair issues, keeping you cool on the hottest days. We’ll explain the problem, explain why it happened, and suggest ways to fix it yourself. A qualified HVAC technician can keep your AC running smoothly and efficiently for years to come.

6 AC Repair Issues and Their Solution

Let’s take a look at the six AC repair issues which occur commonly:

1. Dirty Air Filter

The most common reason for a broken AC is a dirty air filter. A clogged filter reduces airflow, which can cause the unit to freeze up. Check your filter every month and change it according to the manufacturer’s instructions (usually every 1-3 months)

2. Tripped Circuit Breaker

A tripped circuit breaker or a blown fuse can cause your air conditioner to stop working completely. Check your breaker box and reset the breakers if they trip. If the breaker trips again, call a professional. Blown fuses are less common, but they can also cause problems. If you know how to change fuses, make sure you get the right one for your device.

3. Faulty Thermostat

A faulty thermostat with heating services won’t send the right signals to your AC, so it won’t cool properly or the unit would run constantly. Check if the thermostat is set to “cool” and the temperature is lower than the room temperature. If it seems okay, think about replacing the batteries or getting a professional to fix it.

4. Frozen Evaporator Coil

This happens when the evaporator coil becomes too cold and forms ice. A dirty filter, blocked vents, or low refrigerant levels can all cause this issue. Turn off the AC and let the ice melt completely before turning it back on. After it starts again, fix the problem by replacing the filter, cleaning the vents, and having a professional check the refrigerant.

5. Weak Airflow

If your AC is running, check for weak airflow. Airflow can be limited by blocked vents, dirty filters, or clogged ductwork. Make sure vents are open and furniture is not blocking them. Replace the filter and consider hiring a professional to clean the ducts if the airflow is still poor.

6. Blocked Drain Pan

A blocked drain pan or drain line can cause water to back up and leak from your AC unit. Find the drain pan under the indoor unit and empty it carefully. You might need to use a thin wire or compressed air to clean clogged drain lines.

Final Words

The DIY fixes mentioned above can fix some common AC problems, it’s important to know your limits. If you have trouble or the problem seems complicated, call a professional HVAC technician to diagnose and fix it.  A well-maintained AC not only keeps you comfortable, but also makes it more efficient and lasts longer.
