-
How long does a ductless mini-split system last?
If regularly maintained, a ductless mini-split can last 15 to 20 years. It’s one of the most durable HVAC systems, making it a popular and energy-efficient choice.
-
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 often do I need AC maintenance?
For optimal system performance, we recommend scheduling AC maintenance annually. We recommend scheduling a tune-up with our team in the spring to make sure your AC is ready to operate efficiently all summer.
-
Is a ductless mini-split system more efficient than a traditional HVAC system?
Yes. Due to their lack of ductwork, mini-split systems generally offer better energy efficiency than traditional HVAC systems.
-
Will a ductless mini-split heat and cool my entire home?
If properly installed, a ductless mini-split system is a whole-home solution. A single indoor and outdoor unit will exchange or remove heat, allowing you to control and modify the temperature in every room individually.
