Frequently Asked Questions

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 long should my ductless mini-split system last?
If your system gets regular quality maintenance, it could last as long as 15 to 20 years, though multiple factors, such as usage frequency, will affect your specific system’s lifespan.
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.
How long do heat pumps last?

You can expect a heat pump to last about 15 to 20 years with normal usage and routine maintenance.
How does a gas furnace work?

With a gas furnace, combustion gasses like propane or natural gas are ignited and used to warm the air blown from the furnace fan before it’s blown into your ductwork, and throughout your home.
