Top 4 risks of DIY air conditioner installation

DIY air conditioner

Air conditioning is a system that cools down the temperature inside the space by removing the heat and moisture from the room.

The system takes the warm air in and cools the air, but this includes many parts.

In-home air conditioners, a fluid is cooled and evaporated into another fluid called refrigerant. AC converts the gas into a liquid and again uses the chemicals that help remove the warm air inside the home. In simple words, AC controls the temperature, air quality, and humidity in indoor spaces.

Air conditions are installed in the home and in cars to improve comfortability. The sale of air conditioners has increased immensely as the needs of the consumers.

Types of air conditioners

Air conditions are of different types. Which one you want to choose depends on your needs.

Split unit Air conditioning system

The spilled system is wall-mounted, consisting of an indoor and outdoor unit. The outside unit gets installed on the room’s exterior wall, which includes the compressor, condenser coil, and expansion coil.

The indoor unit is installed on the room’s inner wall, and it contains the cooling coil and air filter. Both the indoor and outdoor units are connected through wires and tubing.

Split systems are much quieter than the compressor, and the fan is located outside the room. It can connect more than one indoor unit with the same outdoor unit.

Packaged AC

A packaged air conditioner has all the parts enclosed in one single box, which is usually located outside the wall or roof of the building. One indoor air handler cools the air inside and sends the heat and humidity out of the home.

These types of air conditioners are helpful in commercial buildings or large houses. They can be connected to multiple ducts, which can be laid in various rooms.

With the use of electricity as its power source, the refrigerant is circulated through coils which cools the air in the room and absorbs the warm air.

Central air conditioner system

Find AC installation which is used in gyms, large homes, buildings, and offices. These are the most common type of AC, which helps to cool the air quickly and efficiently in larger areas.

It is the same as the other air conditioners; a coil filled with refrigerant is used to cool the air, blown out of the fan. This air is then circulated through the ducts in the entire building. The ducts absorb the heat from the room and transport back this air, and then it is pushed outside.

Portable air conditioner

It’s a mobile unit it doesn’t permanently install. They are very easy to install, and they help remove the heat from the air in the room through a small exhaust fan.

This is a movable unit which can be moved from room to room as per the requirement. But while moving, the unit always takes care.

These days, the air conditioner has a manual option through which you can switch on and off the unit as per your requirements. You need not have to rely on the thermostat to adjust.

There are automatic options also in which you have to do a little work by setting the options in the unit according to your requirements.

These options help the unit to turn on and off automatically as the room temperature reaches that point.

 DIY installation of AC

People sometimes install the AC themselves, which can be done in the following steps.

  • First, select an unobstructed location on the outer wall.
  • Always secure the mounting wall in the interior wall
  • Drill a hole in the wall to feed the pipes outside.
  • Check all the electrical wire connections of the indoor unit.
  • Run the pipes through the holes and pass the wire through them. Then connect them to the unit.
  • Now secure the indoor unit to the mounting plate.
  • After this, install the outer unit.
  • Connect both the units and then switch on the AC and enjoy the cool air.

But this can be risky as the self-installation is a bit unreliable. The professionals can do better AC installation and in a perfect manner.

Safety issues

The AC units utilize large amounts of electricity, and this includes a greater risk of electric shock when used by untrained people. Sometimes accidentally, the wires that get short can also damage the home electrical systems—fire or damage to the electrical component or equipment in the house. Leakage in the refrigerant has to be handled with care.

Air conditioners make life comfortable and cozy. It involves many dangerous things attached to it. These include:

  • The natural gases in the AC can cause fire or explosion.
  • Touching the wrong electrical components can result in electric shocks
  • Carbon monoxide or gas fumes leak from vents due to improper AC system installation.

The safety of people who are using the AC system can cause disastrous conditions, affecting all the people in the family.

It affects the efficiency of the equipment and higher costs.

DIY AC is supposed to help save money, but sometimes DIY air conditioning repairs themselves may cost more than simply getting it done by the professionals.

Many tools and devices are specially designed for repair in centralized air conditioner repairs.

These tools are not easy to use and are not even available. So it is not a good idea to DIY the repairs of the AC system. This can also affect the efficiency of the system. These tools are not standard household tools; this can be very costly for you.

Even at the time of repair, the appliances get heated or cooled and running again, which can affect the system in its operations at peak efficiency. If an untrained person is handling the repair, it’s easy to make mistakes, and this can spoil the system.

Warranty void

As AC needs uncountable modifications as exceptions. This can void the warranty substituted with an air conditioner. If repaired or installed by self, the company can void all the warranties associated with it.

Even substituting the small components or using a different type of refrigerant can increase unauthorized modification.

All the warranties are valid until all the repairs are done by professions and maintained adequately. Once again, if you are saving a little cash by doing all these repairs DIY, this could end up costing you considerable time.

Illegal and more extended repair time

The environmental protection agency has strict laws to handle the system that utilizes refrigerants. In many areas, professionals are only allowed to repair the air conditions, which is an illegal activity.

Before repairing the air conditioner yourself, always check that this law applies to your area or not. It is advised to play safe by hiring a professional to repair the air conditioner to avoid unwanted legalities to bear.

The repairs of the air conditioner should be repaired quickly as soon as possible. In the heatwaves, it is tough to live without an air conditioner. So repair the AC as soon as possible.

It is always advised to hire a professional to diagnose the problem and get the best solution. If you attempt to do this yourself, this may troubleshoot and assemble your tools, take the system apart, etc.

Repairs that you can do yourself

There are several things that you can do yourself and should always do to keep your air conditioner in an active position. These all fall in the category of maintenance, not repair.

Clean the outer air conditioner unit

Many times, it has been seen that the outdoor unit is placed outside of the house, so it is usually clogged with dirt, leaves, and other debris from the yard. You can clean it yourself for further protection measures involving foliage surrounding the unit than always contact the professional.

Change air filters

It is easy to change and clean the air filter for better performance of the air conditioner. You can check the filter monthly whenever it looks greyish or dirty, then change the disposable filter and clean the permanent one. The life of the air filter is 90 days.

Install or replace insulation

If the insulation is repaired, this will affect the AC system more than the performance and energy saving. If you haven’t insulated your house yet, then do this quickly. If you have done so, replace it to avoid the dirt or damages that can harm the people’s health in the home.


There are many things for which you should hire a professional instead of doing it yourself. If there is refrigerant leakage, dirty evaporator coils, and fan malfunctioning, it is advisable to contact the professional instead of doing it yourself.

The professional will always give perfect advice for the repair or replacement of the air conditioner.
