How much does it cost to install a mini split system for a 1500 sq ft house?

There’s no one-size price for a 1,500 sq ft home. Your total depends on zones/heads, brand, and any electrical upgrades. Endless Energy confirms costs after a site assessment and Manual J sizing. Mass Save instant rebates up to $16,000 can reduce out-of-pocket. 0% HEAT Loan financing is available on qualifying projects. A $500 off mini-split promotion is currently listed. We handle permits, rebate paperwork, and warranty registration. A 10-year limited labor warranty option is available and requires annual maintenance.
