A Ductless Mini Split Is the Best HVAC Solution for Your Home Addition in Washington

Congratulations, you’re planning an addition to your Seattle-area home. Now, what are you going to do about cooling and heating it?

Our team at Resicon doesn’t recommend extending the ductwork from your central HVAC system into your new space. Duct extension requires cutting through walls and often altering your home’s framework. It also changes the static pressure in your HVAC system, which can strain your blower motor.

Even if you run new ducts to an addition, your new space will be farther from the thermostat and likely won’t match the temperature in the rest of the house. It will be either too cold or too hot.

Why Install a Mini Split in Your King County Home?

The smartest, least invasive, and most energy-efficient choice for homeowners in Tacoma, WA, is a ductless mini split system. It is independent of your central HVAC and doesn’t require ductwork. It’s the perfect solution for home additions, attached and detached garages, sunrooms, and guest houses.

At Resicon, we love that highly efficient ductless mini splits use less electricity and no fossil fuels, making them much kinder to the environment than traditional systems.

Let’s take a closer look at ductless mini splits to help you decide if they are the best way to heat and cool your home addition.

What’s Wrong With Extending Ductwork?

Standard central heating and cooling systems are sized to the exact square footage of the original house. When you slap an addition onto that system, you throw off the balance between static pressure, airflow, and blower capacity.

Because your existing furnace blower was never sized to push air down yards of newly installed ductwork, the airflow could weaken, leaving your addition freezing in winter and hot in the summer.

Ductwork air loss compounds the weak airflow. You may have pristine new ductwork extending to your addition, but if its connection to the system’s main trunk line is loose, air will escape. If there is a hole or crack somewhere in the main trunk line, air escapes. In both instances, the system pressure drops, resulting in reduced airflow.

How Common Are Ductwork Air Losses?

Duct air loss is not unusual. ENERGY STAR^® notes that 20 to 30 percent of the air flowing through a residential duct system is lost because of leaks and poor connections.

Whether you are exploring HVAC for a home addition in Fircrest or planning a mini-split for garage heating, going ductless keeps installation clean, fast, and non-invasive. Plus, you’ll get more reliable, consistent airflow from a mini split. With no ducts, there are no duct air losses!

How Ductless Mini Splits Work

A ductless mini split has a compact outdoor compressor unit and one or more sleek indoor air-handling units mounted on your walls or ceiling. Each air handler works independently and has its own thermostat. The more indoor units you add, the more costly the system.

The indoor and outdoor components connect via a conduit that holds the power lines, refrigerant tubing, and a condensate drain.

A mini split heats and cools your living spaces like a heat pump, using refrigerant to move heat in and out of your home. Instead of forcing air through dusty metal ducts, a mini split delivers conditioned air directly to the rooms where an indoor unit is installed.

Why Are Mini Splits So Energy-Efficient?

Inverter-driven variable-speed technology gives them a leg up over heat pumps, air conditioners, and furnaces. Other basic HVAC systems are like light switches. They either run at capacity or turn off. There’s no in between.

Mini split compressors constantly speed up or slow down to match the exact heating or cooling load required. They maintain a steady temperature without wasting energy.

Even a ductless system with multiple indoor air-handling units can be economical to operate. When evaluating the ductless system cost in Puyallup, many homeowners are surprised to learn that long-term savings on monthly utility bills can offset the investment in a multi-zone setup.

Plus, none of the costs associated with duct extension, such as drywall repair, apply to mini split installation.

Mini Splits Offer Zoned Temperature Control

One of the best perks of adding a mini split to a home addition is zoned heating and cooling.

When you look into single-zone mini split benefits, the standout feature is the ability to control the temperature independently of the rest of your home.

Let’s say your home addition is a guest bedroom. When it is unoccupied, you can dial back the temperature to save energy without affecting other living areas.

If your addition consists of two or more rooms—a multi-zone configuration—you can cool and heat each zone independently of the others and your main living area.
