New Mini-Split installation by SHR A/C & Heating always comes with a 2 year labor warranty at no additional charge. Small air conditioning systems have been around for a long time but now that has been reimagined into the Mini-Split Air Conditioning & Heating system. This is just like a regular split air conditioning system but the Mini-Split hangs on a wall inside keeping from having to send your air from inside the house into the attic. This alone increases the efficiency of keeping that room cold. We install new mini-split air conditioning systems to replace old ones, but mostly we add them to the house for add on areas and garage conversions and the such. The best part about this unit is it’s efficiency.
