Frequently Asked Questions

Have questions? We are here to help. Still have questions or can't find the answer you need? Give us a call at 602-698-8912 today!

How often should a ductless mini-split system be serviced?

We recommend a twice-a-year maintenance schedule to ensure your system runs efficiently. These tune-ups can extend the life span of your system and allow our technicians to catch and fix minor problems before they become major issues.
Should my heat pump be repaired or replaced?

Usually, a professional repair is sufficient to get a heat pump running properly again. However, if your system needs frequent repairs or is over 15 years old, your money is better invested in a new system. Our team can help you determine which option is best for your system and home.
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.
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.
Do air scrubbers use a lot of energy?

Most air scrubbers use little energy, often less than a single lightbulb. Plus, they can help keep your HVAC system running more efficiently by eliminating many particles that could clog its filter or collect in the ductwork.
