Is a ductless HVAC system a good option for me?

Updating older buildings with heating and air conditioning is next to impossible, especially if there’s not enough space to install ductwork. For buildings that do have space, the expense of these updates can be a bit high for customers. The workaround on both ends is ductless heating and cooling units.

Ductless HVAC systems are compact and can be installed virtually anywhere, without the need for duct installations. Ductless HVAC units are also the perfect solution for modern infrastructures dealing with holes and gaps in ductwork that cause air leaks. Rather than paying for expensive replacements, they can opt to go with ductless HVAC systems.

Ductless systems from Trane/Mitsubishi Electric are versatile, affordable, and efficient in handling your indoor comfort, and when you trust Ashley Heating, Air & Water with installation, your start-to-finish project is done well and on time.

What is a ductless HVAC system?

True to its name, a ductless system provides heating and cooling solutions where ductwork doesn’t currently exist or where it’s simply not feasible or cost effective to install. There’s no need to tear out walls or ceilings – a ductless system involves little more than a small hole in the exterior wall, and most installations can be completed in a day. This makes it ideal for cabins, new additions, sunrooms, bedrooms, basements, garages, or shops.

Ductless systems are also a good option when you’re looking to replace unsightly window units, space heaters, or old baseboard heating.

Types of ductless HVAC systems

Here at Ashley Heating, Air & Water, we proudly offer Trane/Mitsubishi Electric products, the top-selling brand of ductless systems. We have a wide variety of products designed to help you enjoy cleaner air and superior control of cooling, heating, and your energy bill.

Ductless systems come in two main types: single-zone or multi-zone. A single-zone system cools and heats a single space. Multi-zone systems are designed for cooling and heating multiple spaces (up to eight zones), allowing you to control the temperature room by room. So, if you want your kitchen to be 72 degrees but a bedroom to be 75 degrees, you can do that, and the system only uses the precise amount of energy needed to keep each room at the proper temperature.

Ductless HVAC components

A ductless system has three main components: an outdoor unit, indoor unit(s), and smart comfort controller.

  • Outside the home, there is a compact outdoor unit that connects to a max of eight indoor unit(s). Trane/Mitsubishi Electric outdoor units are much smaller and quieter than conventional outdoor units.

  • Inside the home, each zone is served by its own indoor unit allowing you to control temperature room by room. For example, in a multi-zone system with five zones, there is one outdoor unit and five indoor units. Indoor units are quiet, easy to operate, streamlined (approximately seven inches deep), and come in 12 different sleek designs that can be wall-mounted, floor-mounted, or ceiling-mounted. Each indoor unit has its own advanced air filter that helps you breathe easier.

  • A controller device lets you control your comfort and easily monitor energy usage. You can choose from a variety of wireless, wall-mounted or handheld controllers.

How it works

The system works by transferring heat to and from an outdoor unit to one or more indoor units. The units are connected by small pipes containing refrigerant, a substance that absorbs heat. The system works in all Treasure Valley temperatures – extreme hot to below zero temps.

The outdoor unit is equipped with INVERTER technology which enables it to quickly change the amount of power it uses and the amount of refrigerant it transfers to and from the indoor units. The outdoor unit only uses the precise amount of power needed to reach each zone’s preferred temperature.

Conventional vs. ductless HVAC systems

Conventional air conditioning has a big outdoor unit that kicks on when your house gets too warm and runs at full power until the entire house reaches a set temperature. Each time the noisy outdoor unit turns on, it uses a lot of energy. A furnace basically does the same thing for heating (although it’s not located outside). Both the AC and furnace use ductwork to blow air throughout your house.

A ductless system, on the other hand, is an all-in-one solution that provides both heating and cooling where ductwork doesn’t exist. Ductless systems allow you to control temperature room by room. So, if you want your kitchen to be 72 degrees but a bedroom to be 75 degrees, a ductless system lets you do that and reduces energy consumption by up to 40 percent in the process. It’s an extremely quiet and efficient way to heat or cool your house.
