Ductless mini splits are a good option for many Spokane homes, especially older homes, additions, garages, and rooms without existing ductwork. A mini split system can provide efficient heating and cooling while giving homeowners more control over specific areas of the home.
The size of evaporative cooler a home needs depends on square footage, ceiling height, airflow requirements, insulation, and how the home is laid out. An undersized unit may not provide enough cooling, while an oversized unit can create excess humidity and poor performance. Proper sizing is based on how much air the system needs to move through the home. A professional assessment is the best way to determine the right fit.
Swamp coolers can work well in Spokane Valley because evaporative cooling performs best in dry summer conditions. Their effectiveness depends on outdoor humidity levels, airflow, home layout, and how well the system is installed and maintained. They are usually less effective during periods of higher humidity. A home evaluation can help determine whether a swamp cooler is a practical cooling option.
Ductless mini split systems are highly energy efficient because they transfer heat rather than generate it and avoid energy losses associated with ductwork. Many systems use variable-speed technology to adjust output based on demand, reducing unnecessary energy use. Efficiency depends on proper sizing, installation, and home conditions. When installed correctly, mini splits can lower overall energy consumption compared to traditional systems.
The number of mini split units needed depends on the size of the home, layout, insulation, and how many separate areas require temperature control. Some homes can be served by a single unit, while others need multiple indoor units connected to one outdoor system. Each space is evaluated individually to ensure proper coverage and efficiency. A load calculation is typically used to determine the correct number of units.

In simple terms, a humidifier works by adding moisture back into dry indoor air. It does this by turning water into vapor or a fine mist and distributing it through your home. This helps balance humidity levels, especially during winter when heating systems can dry the air out. If you’ve noticed dry air in your house (like static shocks, dry skin, or irritated sinuses) a humidifier is designed to fix that by restoring moisture to a healthy range, typically between 30% and 50%.
