The ductless mini split heat pump system is an option for heating and cooling that has been growing in popularity. Instead of operating through a network of ducts connected to an indoor air handler and evaporator unit, a ductless AC system breaks up the indoor unit and the blower fans to distribute conditioned air throughout your home in the form of mini air handlers, mounted high on the wall.
If you’ve ever been in a home and seen something on the wall that looks like a window AC unit but it doesn’t go back through the wall, then you’re looking at a component of a ductless system. These wall units are each hooked up to a single outdoor unit, creating a central heat pump system without the use of air ducts. This form of air conditioning is very efficient and beneficial in a number of ways. There are also some unique maintenance and repairs that are important to be aware of when it’s time to service your system.
Read on to learn what those are and don’t hesitate to call our Centennial HVAC or Denver HVAC pros if you have any questions or need to schedule service!
Each wall-mounted air handler has a series of connections routed through a hole behind it, including a power line, refrigerant line, and condensate line. The last one removes moisture from the cooling process so it doesn’t enter your home. With poor installation or structural problems, a leak can occur. While rare, a leak behind an air handler can lead to that air handler separating from the wall.
Speaking of broken air handler, this is one problem you’d never have with a conventional AC, but that’s not necessarily a bad thing. In fact, it’s somewhat of a benefit! If you have a single broken air handler, you’re still able to receive conditioned air from the other air handlers in your home.
This issue is not just unique to ductless systems, however, it’s an important one to be aware of since the leak has the potential to seep into your home rather than outside. A refrigerant leak can typically be detected by a hissing sound or loss of cooling power from your air conditioner or the affected air handler. Be sure to call for repairs right away if you suspect you have a refrigerant leak!
Ductless mini split heat pumps offer efficient and versatile heating and cooling for your home. While they have many benefits, it’s important to address potential issues before they become major problems. Regular maintenance and prompt repairs will keep your system running smoothly.
