How much does it cost to install a central air conditioner?
Central air installation pricing varies by home and system. A technician will confirm costs after an on-site assessment and Manual J sizing. Factors include home size and layout, ductwork condition or additions, refrigerant line-set replacement, equipment brand and efficiency, and rebate eligibility. We offer $500 off an AC-only system and 0% financing with payments as low as $120/month. We handle permits, rebate paperwork, and warranty registration to simplify the process in Boston and nearby.
