-
How can I best maintain my ductless mini-split?
Enjoy zoned temperature control for longer with simple at-home steps. We recommend you replace your air filters every other month and keep coils free of dust. Regularly check outdoor units and keep the area around them clear of dirt buildup or debris. Scheduling annual maintenance will ensure minor problems with your system don’t become a major expense.
-
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 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 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.
-
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.
