This article discusses some of the most common mistakes people make when installing an air conditioner and how to prevent them from occurring. It also provides advice on how to ensure a successful installation of an air conditioner. Read on.

Selecting the Wrong Unit Size

When installing an air conditioner in your home, it is essential to make sure that you select the right size for the space you are trying to cool. If the unit is too big, it will cycle on and off too frequently and won’t properly dehumidify the air, leading to higher energy bills. 

If the unit is too small, it won’t be able to keep the space cool enough, leading to unnecessary strain on the unit and shortening its lifespan. Picking the right size air conditioner is essential for proper cooling and energy efficiency.

Neglecting the Drainage System

As an air conditioner runs, it produces a considerable amount of moisture. If this moisture isn’t taken care of appropriately, it can harm the environment around it. This could damage your house, including compromised walls, blocked pipes, mold, and odors. It’s too common for homeowners to neglect the importance of a proper drainage system for their air conditioners, resulting in water damage in many homes.

If you’re uncertain how to properly install your drainage system, it’s highly advisable to contact a specialist. They will be able to install the system correctly and make sure it will remain in good working condition over time.

Installing the Thermostat Incorrectly

Most people don’t understand that where the thermostat is placed can influence how their heating and cooling system works. But it definitely has an impact. Installing a thermostat in the wrong place can cause an air conditioner to work harder than usual. This is a prevalent mistake and can cause the AC to become less efficient than it should be.

It is best to set up your thermostat away from air vents where the temperature does not fluctuate quickly and in an area that does not get too much direct sunlight. By doing this, your thermostat will be able to measure the temperature accurately, and your air conditioning system will operate more efficiently.

Ignoring the Condenser

The condenser in your air conditioning system is an essential part of its operation. If running efficiently, it will help your air conditioner use less energy and last longer. This will allow you to save money on energy bills and enjoy your AC for a longer period.

To reduce strain on an AC condenser, it is vital to make sure that it is properly maintained and that it is not placed in an area that is too hot or exposed to direct sunlight. Additionally, it is crucial to make sure that the condenser is not blocked by anything that can obstruct the airflow around the unit.

Adding Too Much Refrigerant 

You’ve got the AC system installed and all ready to go. But you added too much refrigerant, and it’s not working correctly. Don’t take any chances with your air conditioning system! Be sure to always add refrigerant according to the manufacturer’s instructions. Adding too much refrigerant can damage your system, resulting in costly repairs. 


Proper AC installation is essential to ensure your AC unit works efficiently and effectively. It is a complex process that requires the expertise of a qualified technician.
