Air Conditioning Troubleshooting Tips Every Homeowner Should Know

AC Troubleshooting

An air conditioning unit is an indispensable household appliance. This is especially true if you live in a place where summers can get unbearably hot and humid. A working AC just makes the outside heat more bearable which is why it can be such a nightmare when your home air conditioner starts acting up. Thankfully, problems like these can be easily fixed by a reliable HVAC contractor. It doesn’t hurt, however, to learn AC troubleshooting skills before calling the experts in to give you a better grasp of the current state of your cooling unit.

The air conditioner won’t start

There is nothing more frustrating than turning the AC on and realizing that it just isn’t starting. Most of the time, however, the cause can be as simple as a blown fuse. This can happen too if your circuit breaker trips. Fortunately, both these problems can be resolved just as easily. The costs involved are minimal as well, since you will only need to replace the failing fuse. In the case of the tripping circuit breaker, resetting it will usually address the problem.

Issues with the wiring may also be causing the problem. If this is the case, then you will have to get the professionals to fix the issue. In addition, problems with the thermostat can also cause the air conditioner to fail.

Thermostat issues

If the thermostat is improperly calibrated or is malfunctioning, it will be unable to communicate with the air conditioner. This prevents the unit from kickstarting. This problem is more common among the older models. However, even programmable thermostats aren’t immune to these issues. This is especially true if they have not been programmed properly to begin with.

AC is way too loud

If you’ve noticed that your air conditioner seems louder than normal, then it is best to start your troubleshooting steps by checking the fan motors. Responsible for cooling the air, the fan motors are responsible for pushing the warm air towards the evaporator coil. However, the fans can start giving off some loud and distracting noises if they get damaged. They can get a bit noisy too if they are clogged with debris and dust. The best thing to do is call in an HVAC professional to check out the unit so proper repairs are carried out and for further damage to be prevented.

Leaky and damaged ducts

If your ductwork seems to be suffering from leaks, this can drag the overall efficiency of the AC. Not only is this going to lead to increased humidity indoors, it is also likely to result in some expensive monthly utility bills.

Blocked drain

When the drain is clogged, excess moisture can build up into water. When this backs up, it can cause considerable damage to the system.

The condenser coil is clogged

A crucial part of the air conditioner is the condenser coil. It functions by releasing hot air out of your living space. However, the condenser coils are located in the outdoor unit. As a result, it is constantly exposed to dirt, dust, and all forms of debris. Over time, it can get clogged which will lead to it not doing a very good job of pushing the hot air out. When this happens, the cooling system will have to work harder yet your indoor space will not be any cooler.

Frozen evaporator coil

When your filters are dirty and clogged, there will be reduced airflow within the system. The same could happen when there are leaks in the ducts or the system is almost running out of refrigerant. This results in the evaporator coil getting covered in ice and as a result, the AC will produce warm, instead of cold air.

Check your indoor environment

Leaving your doors and windows open with the AC running is never a good idea. This can significantly affect its overall efficiency and its ability to produce cool air for your indoor setting. Keep the doors and windows shut when the AC is on. Make sure that no furniture pieces and other fixtures are positioned too close to the unit.

After you have tried all these basic Air conditioning troubleshooting steps and nothing seems to fix the problem, the best thing to do is to call the experts in. Find a credible and experienced HVAC specialist whom you can rely on to carry out the necessary troubleshooting steps to diagnose what the problem is and fix it in no time.
