Did you know that in San Diego, only about 10.8% of homes sold in the past year had central air conditioning? This means that many homeowners are missing out on the benefits of a comfortable indoor temperature during the hot summer months.

The process of installing air conditioning can seem daunting. Especially if you’re not familiar with the technical terms and concepts involved. But don’t worry!

In this article, we’ll walk you through the basics of air conditioning installation, including energy efficiency and climate considerations. By the end, you’ll have a better understanding of what to expect and be ready to make an informed decision about your AC installation.

Climate and Lifestyle Considerations

Before installing an air conditioner in your San Diego County home, it’s important to consider the climate. San Diego has a mild Mediterranean climate, characterized by dry summers and rainy winters. The temperature during summer can range from 70°F to 80°F, with occasional heat waves that can push the temperature above 90°F.

To determine the right size air conditioner for your home, you need to consider the size of your house and the number of rooms you want to cool. You also need to think about your lifestyle and how much time you spend at home.

If you’re at work during the day and only need to cool your home in the evenings and weekends, you may not need a large air conditioner. On the other hand, if you work from home or have a large family, you may need a more powerful air conditioner to keep your home cool and comfortable.

Energy Efficiency

When considering an AC installation for your San Diego home, energy efficiency is an important factor to consider. Energy-efficient air conditioners use less energy to cool your home, which can lead to lower energy bills and less strain on the environment. There are several factors that can affect the energy efficiency of your air conditioning system, including:

Type of Air Conditioner

There are different types of air conditioners available, including central air conditioning, ductless mini-split systems, and window air conditioners. Each type has different energy efficiency ratings, so it’s important to choose one that meets your needs and budget.

SEER Rating

The SEER (Seasonal Energy Efficiency Ratio) rating is a measure of how efficiently an air conditioner cools your home over a season. The higher the SEER rating, the more energy-efficient the air conditioner is.

Size of Air Conditioner

Choosing the right size air conditioner for your home is important for energy efficiency. If your air conditioner is too small, it will have to work harder to cool your home, which can lead to higher energy bills. If it’s too large, it can waste energy and money.

Proper Installation

Proper installation is essential for ensuring that your air conditioner runs efficiently. Poor installation can lead to air leaks, inefficient operation, and increased energy usage.

Installation and Maintenance Costs

When considering an AC unit installation for your San Diego home, it’s important to understand the associated costs of both installation and maintenance. Here are some factors to consider:

Installation Costs

The cost of installing an air conditioning system can vary depending on several factors, including the size of your home, the type of air conditioner you choose, and the complexity of the installation. You should always obtain a detailed quote from a reputable HVAC contractor that outlines all costs involved.

Maintenance Costs

Proper maintenance of your air conditioning system is essential for ensuring it runs efficiently and lasts for a long time. Routine maintenance can include filter replacements, coil cleanings, and regular check-ups from a qualified HVAC technician. It’s important to budget for these maintenance costs when considering an AC unit installation.

Long-term Savings

Although the upfront costs of an AC unit installation can be significant, it’s important to consider the long-term savings that a new, energy-efficient air conditioner can provide. Lower energy bills, improved indoor air quality, and increased home value are all potential benefits.

Financing Options

Some HVAC contractors offer financing options to help homeowners manage the upfront costs of an AC unit installation. Be sure to ask about financing options when obtaining quotes from contractors.

System Size and Placement

When installing an AC unit, it’s crucial to consider the size and placement of the system. Here are some things to keep in mind:

Size Matters

An air conditioning system that is too small for your home will struggle to cool the space, while a system that is too large will waste energy and money. A professional HVAC contractor can perform a load calculation to determine the correct size for your home.


The placement of your air conditioning system is also important. The outdoor unit should be placed in a location with adequate clearance and proper airflow. The indoor unit should be placed in a central location that allows for even cooling throughout your home.


The ductwork in your home plays a crucial role in the performance of your air conditioning system. Improperly sized or installed ductwork can lead to poor airflow and reduced efficiency. A professional HVAC contractor can evaluate your ductwork and make recommendations for any necessary improvements.


If your home has multiple levels or rooms with varying cooling needs, a zoning system can help improve comfort and efficiency. Zoning allows for individual temperature control in different areas of your home, reducing the workload on your AC unit and saving energy.

Stay Cool and Comfortable with Air Conditioning

Don’t let the hot and humid weather get you down. Installing air conditioning in your home can make a world of difference in your daily life. With San Diego temperatures reaching the 90s, it’s more important than ever to have a reliable HVAC system.
