How Difficult Is It To Install A Ductless Mini-Split Air Conditioner?

A ductless mini-split, the most common type of mini-split system, can be more cost-effective than a conventional air conditioning and heating system because it doesn’t require any ductwork. Heating and cooling bedrooms and small rooms using a ductless mini-split system are excellent alternatives.

It may tempt DIY enthusiasts to tackle the installation of a split-system air conditioner on their own, but unless they have the proper training and certification, it’s better to leave the job to the pros.

Installing The Mini-Split On Your Own

Putting in an air conditioning unit is probably best left to the experts. Installing the mini split unit is fairly an easy task. The lines are set up quickly and easily.

It has no-tools-required connectors and is pre-charged with refrigerant before delivery. All that remains is to screw the two main units into place and link the line set to the condenser.

Time Required To Install A Mini-Split Unit

The labor time for a professional to install a ductless mini-split system is low, clocking in at just a few hours. Dealing with elaborate multi-room systems can take two or three days.

Drilling the ductless access hole, passing the wires through, mounting the brackets, and finally attaching the micro split unit constitute the entirety of the installation process.

  • Attach the indoor unit to the wall plate securely. 

Installing The Outdoor Unit
