You vacuum your carpeting, sure, and maybe your upholstery from time to time too, especially if it’s dusty. Yet your ductless mini split system? You weren’t aware that you had to vacuum that as well. Do you really?

Yes, vacuuming a mini split is crucial before refrigerant release. That said, it’s not a job you have to do yourself if you don’t feel comfortable. You actually need a special vacuum for this type of job and it does not need to be done regularly like your carpet would.  Your mini split technicians will gladly take care of this task for you.

What Causes a Mini Split to Freeze?

Let’s explain one scenario in which a mini split freezes in more detail.

Mini splits, like air conditioners, use refrigerant. Refrigerant is a type of chemical compound that can absorb heat and then send cool air through the unit. In the case of your mini split, those units are indoor air-handling units.

If you have a leak anywhere in your system this could potentially cause the pressure within the mini split system to drop quite rapidly.

Perhaps you’re bidding adieu to your home after having many happy memories there. You don’t want to leave your mini split for the next homeowners to use, especially because it’s made such a difference in how comfortable your home is, not to mention you love saving money on your energy bills.

Is it possible for you to move parts of your mini split to accommodate your new home setup? What about the whole thing?
