What is a ductless split system?

A ductless split system is a heating and cooling system that connects an outdoor compressor to one or more indoor air handlers via small refrigerant lines, providing targeted climate control without traditional ductwork.

Do MiniSplitWarehouse orders include free shipping?

Yes! We offer fast, reliable free shipping nationwide on all qualifying split air conditioner systems and heat pump orders, with most shipments leaving our warehouse the next business day.

Are your split systems AHRI certified and Energy Star rated?

Absolutely. All equipment distributed through MiniSplitWarehouse meets strict industry efficiency guidelines, featuring advanced DC inverter technology and high SEER2 ratings to maximize energy savings.

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

Sizing depends primarily on your room's square footage. As a general rule, a 9,000 BTU split system covers up to 400 sq. ft., while larger spaces or multi-zone layouts require higher tonnages. Check our sizing guides on individual category pages for exact calculations.

Can I install a split system 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 split air conditioners last?

With regular maintenance - keeping filters clean and having the system serviced periodically - quality split heat pump systems typically last 15 to 20 years.
