-
Can I use a heat pump to cool my home as well?
Yes, heat pumps can both heat and cool your home, making them ideal for year-round comfort.
-
Do I need a dehumidifier in Arizona?
We may live in a desert, but your home can be as humid as the tropics. Cooking and bathing can introduce significant moisture into your home. Installing a dehumidifier can help control mold/mildew growth and maintain the optimal balance for your desired comfort.
-
How does an air scrubber work?
Air scrubbers typically combine UV light with a catalytic process to render bacteria, viruses, and mold ineffective and remove them from the air stream. They often feature a pre-filter to remove other contaminants and allergens like dust, pollen, pet dander, and more.
-
Is a ductless mini-split system more efficient than a traditional HVAC system?
Yes. Due to their lack of ductwork, mini-split systems generally offer better energy efficiency than traditional HVAC systems.
-
Do air scrubbers eliminate odor?
The UV light in an air scrubber can break down odor-causing particles from cooking, smoke, household garbage, and more. This will leave your home smelling cleaner and fresher.
