What do I need to know before installing an air conditioner (1)

Air Conditioner Installation

As summer approaches, the sweltering heat can be unbearable, and one of the most effective ways to stay cool and comfortable is by installing an air conditioner. Air conditioning units not only cool your home, but they also help maintain good air quality and dehumidify the atmosphere. However, it’s essential to consider a few factors before purchasing and installing an air conditioner to ensure it meets your needs and operates efficiently. This article outlines the key points you need to know to make an informed decision.

Determine the type of air conditioner suitable for your needs

There are various types of air conditioners available in the market, each with its own benefits and drawbacks. The most common types include central air conditioning, window units, portable air conditioners, and split or ductless systems. Your choice will depend on factors such as the size of your home, the climate in your region, and your budget.

Calculate the required cooling capacity

The cooling capacity of an air conditioner is measured in British Thermal Units (BTUs) per hour. To determine the appropriate capacity for your space, you will need to consider the size of the room, ceiling height, insulation, and the number of occupants. As a general rule, a room of 150-250 square feet requires an air conditioner with 5,000-6,000 BTUs, while a larger space of 450-550 square feet may need 10,000-12,000 BTUs. An air conditioner with too little capacity will struggle to cool the room, while an oversized unit will consume more energy and may not remove humidity effectively.

Energy efficiency is key

Energy efficiency should be a priority when selecting an air conditioner, as it will significantly impact your energy bills and carbon footprint. Look for units with a high Seasonal Energy Efficiency Ratio (SEER) rating, which is a measure of the cooling output divided by the energy consumption. The higher the SEER rating, the more energy-efficient the unit. Additionally, look for ENERGY STAR certified models, as they often exceed the minimum federal standards for efficiency.

Consider the installation location

The location of your air conditioner will play a crucial role in its effectiveness and efficiency. For window units, select a window that is shaded and can support the weight of the unit. Avoid placing air conditioners near heat-producing appliances, as they can affect the thermostat reading and cause the system to work harder than necessary. For split systems, ensure that the outdoor unit is installed in a well-ventilated area away from direct sunlight and has enough clearance for proper airflow.

Ensure proper ventilation and insulation

Proper ventilation and insulation are essential for maintaining an energy-efficient and comfortable environment. Inspect your home for any gaps, cracks, or areas with insufficient insulation, and address these issues before installing an air conditioner. Proper insulation will help prevent the loss of cooled air and reduce the workload on your unit.

Hire a professional installer

Although some air conditioning units can be installed by homeowners, hiring a professional installer is recommended for more complex systems, such as central air conditioning and split systems. A professional installer will ensure that the unit is installed correctly, following local codes and manufacturer guidelines, which is crucial for optimal performance and safety. Additionally, they can help you determine the best location for the unit and provide guidance on proper maintenance.

Understand the maintenance requirements

Regular maintenance is critical for the longevity and efficiency of your air conditioner. Some tasks, such as cleaning or replacing filters, can be done by the homeowner. However, more complex tasks, like inspecting and cleaning coils, checking refrigerant levels, and servicing the electrical components, should be performed by a professional. Familiarize yourself with the recommended maintenance schedule and follow it diligently to keep your unit running smoothly and efficiently.

Factor in the costs

Before purchasing and installing an air conditioner, be aware of the costs involved. These include the initial purchase price of the unit, installation fees, and any necessary accessories or modifications. Also, consider the ongoing costs of energy consumption and maintenance. It’s essential to balance your budget with your desired level of comfort and energy efficiency to make the most of your investment.

Noise level

The noise level of an air conditioner can impact your comfort, especially if the unit is installed in a bedroom or living area. Check the noise rating of the unit, measured in decibels (dB), before making a decision. In general, a lower dB rating indicates a quieter unit. For example, a noise rating of 50 dB is considered relatively quiet, while a rating above 60 dB may be considered loud.

Warranty and customer support

Lastly, consider the warranty offered by the manufacturer and the availability of customer support. A reliable warranty provides peace of mind and protection against any potential defects or issues with the unit. Ensure that the manufacturer has a solid reputation and offers good customer support in case you encounter any problems or require assistance with your air conditioner.


Installing an air conditioner is a significant investment that requires careful planning and consideration. By taking into account the type of unit, cooling capacity, energy efficiency, installation location, ventilation, insulation, professional installation, maintenance, costs, noise levels, and warranty, you will be well-equipped to make an informed decision that meets your specific needs and preferences. Stay cool and comfortable while minimizing your energy consumption and environmental impact by selecting the right air conditioner for your home.
