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!

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.
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 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.
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 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.
