Retrofitting Your Home with Ductless AC

When talking about cooling your home, a traditional central air conditioning system has long been the go-to choice for many Californians. There is however a modern, versatile alternative when it comes to ductless system services in Whittier, CA. It’s ductless air conditioning. These systems are commonly referred to as mini-splits. They offer several advantages, especially when retrofitting older homes or spaces without existing ductwork. Let’s talk about the benefits and considerations of retrofitting your home with these systems.

The Basics of Ductless AC

Ductless air conditioning systems consist of two main components. The first is an outdoor unit and the other is one or more indoor air handlers. These components are connected by a refrigerant line and electrical wiring. Unlike traditional central AC, these systems don’t rely on ductwork to distribute cool air throughout your home.

Advantages of Retrofitting with Ductless AC

  • Retrofitting an older home with traditional ductwork can be expensive and disruptive. Ductless systems offer a much simpler installation process. All that’s needed is a small hole for the refrigerant line to connect the indoor and outdoor units. This makes it an ideal solution for homes without existing ducts.
  • Ductless systems allow for zoned cooling. This means you can set different temperatures for individual rooms or areas. This level of control can help with energy savings and personalized comfort for each family member.
  • These systems are very energy efficient. With no ductwork to leak or lose energy, they can be more cost-effective in the long run. Many models also come with energy-saving features like programmable timers and smart thermostats.
  • There are no ducts, so there’s no chance for dust, allergens, or contaminants to accumulate and be circulated throughout your home. This can improve indoor air quality.
  • The units can be installed in various configurations, including wall-mounted, ceiling-recessed, or floor-standing options. This flexibility allows you to choose the best setup for your space and aesthetic preferences.
  • They are known for their quiet operation. The indoor units produce minimal noise.


While these systems offer long-term energy savings, the initial installation cost can be higher than traditional window units. Despite this, their versatility and efficiency often make up for the upfront expense. You’ll also need to consider the placement of indoor units and their impact on the aesthetics of your space. When you do determine where you want them, proper installation is important for the effectiveness and efficiency of the system.

Retrofitting your home with ductless air conditioning can be a smart and efficient cooling solution. This is even more prudent if you have an older home without existing ductwork. The ease of installation, zoned cooling, energy efficiency, and improved indoor air quality make ductless systems an attractive choice for many homeowners. With ductless AC, you can enjoy personalized comfort and cost savings without the need for extensive ductwork.
