How do I calculate what size BTU system I need for my room?

Can I install a mini split myself, or do I need a professional?

It depends on the model. We offer specialized DIY-friendly kits with pre-charged quick-connect line sets for straightforward setups, as well as standard units that benefit from professional HVAC installation to ensure compliance with local codes.

How long do mini split air conditioners last?
