AC systems are more complex than they seem at first glance. Many parts are assembled to create the final product. Some of the main components of the AC are the compressor, fan, pipes, evaporator coils, and furnaces.

The internal components inside the appliance can be more complex and challenging to reach and fix. If you don’t know what you’re doing, AC repair can also be dangerous.  ACs are shielded by different layers of protection and by the AC housing.

According to Houston AC Repair Service, an AC can have many issues over its life. There are some issues that people can handle on their own, but in most cases, you should have your HVAC unit inspected by a pro.

When your AC no longer functions properly, you should be aware that your repairs may not fix the issue or may not last. Due to their training and expertise, a professional technician might prolong the lifespan of the AC.

On the other hand, if you do it, you may speed the unit’s demise. Below are some of the most common issues most homeowners can fix without assistance.

Start With Cleaning

A thorough cleaning may fix the problem. Dust and other types of dirt build up in the AC unit and block airflow.

The external unit can attract leaves or branches due to its fans. Turn it off and clean the fan with a broom. You can remove the fan guard, but use caution, even if the unit is shut off.

You can blow the dust away inside the cabinet or use a rag to clean as far as possible. The AC should be turned off to avoid accidents, and you also need to ensure there is no electrical power going through the cables. In other words, turn the AC off at the circuit breaker. Work accidents can happen if we don’t pay attention.

The Air Filter Change

Changing the air filters is not a complex process and can be done by most people. You need to be sure to buy the proper filter size. ACs use different filter sizes, and it will be a waste of money to buy the wrong filters.

Some manufacturers recommend changing the filter at about three months. In reality, it depends on how much you use the AC, the area you live in, the number of people in your household, the presence of pets, and whether or not people smoke inside.

Some filters may get clogged faster than others. This is an excellent opportunity for owners to practice maintenance and learn more about their AC when changing filters.

Fixing Noises

When the AC is making loud noises, you can try to check where they are coming from. Not all noises can be fixed without professional tools and extensive knowledge. Noises that are coming from a loose screw or from the fan, however, can be repaired in most cases.

We can use some mechanical oil for the fan to ensure the proper rotation. Fans can also be changed by us if they broke or oil is not doing the trick anymore. Loose screws can also easily be fixed by us if we have the proper tools. With a screwdriver and wrench, you can tighten almost all screws in the AC unit.

Repair Leaks

Leaks can make your system function improperly if they are left not fixed. Depending on the type of leak you are dealing with, it can lead to other damage to the AC unit or even to the house via the creation of mold. You can sometimes fix minor leaks when pipes are clogged.

For a loose pipe, you need some tools to retighten it. Also, check the pipe insulation. Poor or worn insulation can lead to leaks.

Issues With the Thermostat

A malfunctioning thermostat may be caused by a low battery. Replacing the batteries does not require too much technical knowledge. Other thermostat problems can’t be easily fixed.

If you can find a troubleshooting guide that came with the unit, you can run through that list of options. Replacing the thermostat may also help, and you don’t have to be much of a handyman to do it.

Unit Not Starting

When the appliance does not start, there are several steps you can take before calling professionals. The first step is to check to see whether the thermostat has the correct temperature set. If it is incorrectly set, the AC may not start automatically.

If your unit still does not turn on, you should check to see if the cables are correctly plugged into the socket. If you have the right tools, you can also check if there is any power in that socket or if the issue is with the AC.

Do not attempt electrical repairs. If the unit is plugged in and you believe that it’s an electrical issue, call an HVAC repair service or an electrician.

Every unit has small electrical components called capacitors. You should never attempt to touch these, even if the air conditioner is off and the power is disconnected. Capacitors store electricity. The best thing to do is to call in the professionals to avoid further shock or further damage to the unit.
