How to troubleshoot your AC unit? This is the most common question asked by homeowners in McKinney. In the middle of the hot summer months, when the warm weather hits, the last thing you can expect from the AC system is to shut off automatically. It is important to maintain comfort in your home to keep your family content. Here are a few most common issues that you can avoid with troubleshooting or easy AC fixes.

How to troubleshoot your AC unit – Common Problems

You can prevent AC problems by conducting an AC troubleshooting exercise.

1. The AC Won’t Turn On

This is one of the most common fears when you start the AC troubleshooting review. For instance, you turn on the AC system but hear or feel nothing. A tripped circuit breaker or a blown fuse can lead to a lack of power. This does not allow the AC system to turn “ON.”

If this is the case, you will have to replace a blown fuse or reset the circuit breaker. Also, loose wiring and thermostat malfunction can lead to this problem. In such a situation, you need to call a professional AC repair company or service. They will send a technician to diagnose the thermostat problem and fix it right away.

2. Thermostat Glitches

If the thermostat is incorrectly calibrated or if it is not working at all, you won’t be able to turn “On” the AC unit. Setting the thermostat to lower temperatures may allow you to turn on the AC.

However, if the problem persists, you have to call the AC repair technician who will recalibrate the thermostat. Depending on its condition, the technician can replace the thermostat.

Calibration problems mostly occur in older thermostats. Sometimes, new thermostats that come with programmable features can undergo problems. When you are looking for ways to how to troubleshoot AC unit, one way is to study the thermostat manually. This allows for programming the thermostat properly.

3. AC not Cooling

A low refrigerant is a common cause of AC not cooling. If the level of the refrigerant is low, it means the technician who installed the AC system previously has not charged it properly. The other reason is that it could have a leak.

If your home is not cooling, call a professional service like Air Repair Pros McKinney for Easy AC fixes. A low refrigerant can’t remove humidity and heat from the air efficiently. Remember, the refrigerant is the most important component of the AC unit.

Although you may discover a leak during the troubleshooting process, it is just a matter of topping off the refrigerant. A low refrigerant is a common sign of the AC leaking. Since you can’t fix this problem yourself, you will need a professional AC technician to fix it. Likewise, if the technician detects multiple leaks, he may ask you to replace the unit.

4. Condenser Problems

When drawing up an AC troubleshooting plan, remember to consider checking the condenser coil. It is an important component that plays a key role.

The condenser carries out the function of discharging the heat, which is removed from the air. This is done by releasing the heat outside the building. The condenser coil is often exposed to soot, dirt, dust, and environmental pollutants, which make it grimy.

Dirty coils interfere with heat transfer and make the AC unit not working properly. It can also cause wear and tear on your system. How to troubleshoot AC unit with a condenser problem? Well, you need a qualified service like Air Repair Pros to get the job done.

5. Frozen Evaporator Coil

How to troubleshoot AC unit? What are the easy fixes? While you embark on the AC troubleshooting process, check the evaporator coil. This component contains refrigerant, which absorbs heat. Diminishing airflow can form a layer of ice on the evaporator coil. If this occurs, the AC system will blow warm air or no air.

The dirty air filters could possibly cause the restricted airflow, obstructed return air in the ductwork, or low refrigerant. Although this is a common problem, you can’t fix it if you don’t have knowledge on evaporator coils.

On the other hand, a professional AC repair service can easily fix this problem. A qualified technician has knowledge, skills, and years of experience to get to the root of the problem and come up with solutions that will keep the AC up and running again.

You must know how to troubleshoot AC unit – and fix the diagnosed problems, but for better performance, call Air Repair Pros McKinney.
