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 long does AC maintenance take?

Our comprehensive AC tune-ups are thorough and can take up to two hours to complete.
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 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.
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.
When should I schedule ductless mini-split maintenance?
We recommend annual maintenance just before peak operating season. If you’re using your ductless mini-split for cooling, schedule a tune-up in the spring. Schedule maintenance mid-fall if you use your system for heating.
