Installing a new air conditioning system is a significant investment for homeowners, and it's essential to ensure that the installation process is done correctly to maximize the system's efficiency and longevity.


While some homeowners may be tempted to save money by attempting a DIY installation, this can often lead to costly mistakes and decreased performance of the system. In this blog post, we will discuss five common AC installation mistakes and how professional installation can help you avoid them.

1. Incorrect Sizing of the AC System

One of the most common mistakes made during AC installation is selecting a system that is either too large or too small for the home. An oversized system will cycle on and off frequently, leading to increased energy consumption and reduced system lifespan.


On the other hand, an undersized system will struggle to maintain comfortable temperatures, resulting in higher energy bills and decreased comfort. A professional installation team will perform a load calculation to determine the appropriate size of the AC system for your home, ensuring optimal performance and efficiency.

2. Improper Ductwork Installation

Another common mistake during AC installation is improper ductwork installation. Ducts that are not properly sealed or insulated can lead to significant energy loss, as cooled air escapes before reaching your living spaces.


Professional installers will ensure that your ductwork is properly sealed and insulated, maximizing the efficiency of your AC system and reducing your energy bills.

3. Incorrect Refrigerant Levels

The refrigerant in your AC system is responsible for absorbing heat from the air and releasing it outside of your home. If the system does not have the correct amount of refrigerant, it will not be able to cool your home effectively.


Overcharging or undercharging the system can lead to decreased efficiency, higher energy bills, and potential damage to the compressor. A professional installation team will ensure that your AC system is charged with the correct amount of refrigerant, according to the Environmental Protection Agency (EPA) guidelines.

4. Poor Airflow and Ventilation

Proper airflow and ventilation are crucial for the efficient operation of your AC system. Blocked or restricted airflow can lead to decreased system performance, increased energy consumption, and reduced indoor air quality.


Professional installers will ensure that your AC system is installed with the appropriate number of vents and that the airflow is balanced throughout your home. This will help to maintain consistent temperatures, improve indoor air quality, and reduce energy bills.

5. Inadequate Drainage

As your AC system cools the air, it also removes moisture, which needs to be properly drained to prevent water damage and mold growth. An improperly installed drainage system can lead to water leaks, damage to your home, and potential health hazards. A professional installation team will ensure that your AC system has adequate drainage, protecting your home and your family's health.
