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!

Are heat pumps loud when operating?

Heat pumps are quieter than many other heating and cooling systems, making them an ideal choice if you’re looking for a quiet system.
What are UV light filtration systems?

UV light systems are units that are installed directly within your ductwork and emit a black light that neutralizes viruses, bacteria, etc., as they flow through your ducts. This can reduce illnesses and make your home smell fresher and feel more comfortable.
Do heat pumps work when it’s cold outside?

Yes, heat pumps even work when it’s cold outside, but the colder it is, the harder they work to do so. That means that as it gets colder, it becomes less energy-efficient. However, they’re ideal for Phoenix’s climate, where temperatures are rarely below freezing.
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.
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.
