-
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.
-
What if maintenance reveals serious problems with my air conditioner?
If we find major issues with your system, we’ll discuss your repair or replacement options. Then, we’ll perform the necessary services to keep your system working well.
-
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.
-
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.
-
How often should I change my air filters?
It depends on the filter and other factors, including whether you have pets in the home, smoke, leave windows open during the day, etc. Some filters will fill up within a month, while others may take three months. Because every home is different, we recommend checking your filters every month until you establish the ideal frequency for your home.
