High-efficiency systems cost more upfront but save money on energy bills. We provide detailed quotes with no hidden fees." } }, { "@type": "Question", "name": "How long does AC installation take?", "acceptedAnswer": { "@type": "Answer", "text": "Most standard AC replacements are completed in one day (4-8 hours). If ductwork modifications or electrical upgrades are needed, the project may take 2-3 days. We'll give you a clear timeline before starting." } }, { "@type": "Question", "name": "What size air conditioner do I need?", "acceptedAnswer": { "@type": "Answer", "text": "AC size is measured in tons and depends on your home's square footage, insulation, window exposure, and local climate. A properly sized system is crucial—too small won't cool adequately, too large will cycle frequently and waste energy. We perform Manual J load calculations to determine the right size." } }, { "@type": "Question", "name": "What SEER rating should I choose?", "acceptedAnswer": { "@type": "Answer", "text": "SEER (Seasonal Energy Efficiency Ratio) measures efficiency. The minimum in Massachusetts is 14 SEER. Higher SEER ratings (16-26) cost more but offer lower operating costs and often qualify for rebates. We'll help you find the sweet spot for your budget and goals." } }, { "@type": "Question", "name": "Do you offer financing for new AC systems?", "acceptedAnswer": { "@type": "Answer", "text": "Yes, we offer flexible financing options to help make your new AC system affordable. We can discuss monthly payment options during your consultation so you can make a comfortable decision." } }, { "@type": "Question", "name": "What brands do you install?", "acceptedAnswer": { "@type": "Answer", "text": "We install leading AC brands including Carrier, Trane, Lennox, Bosch, Mitsubishi, and others. We select brands known for reliability, efficiency, and strong warranty support. We'll recommend options that fit your needs and budget." } } ] } ] --- [![Fong & Sullivan Heating & Cooling](/assets/logo-DRVt-hZl.png)](/) [Home](/) Heating [Boiler Repair](/services/boiler-repair)[Boiler Installation](/services/boiler-installation)[Furnace Repair](/services/furnace-repair)[Furnace Installation](/services/furnace-installation)[Water Heaters](/services/water-heaters) [View All →](/services) Cooling [AC Repair](/services/ac-repair)[AC Installation](/services/ac-installation)[Heat Pump Installation](/services/heat-pump-installation)[Heat Pump Repair](/services/heat-pump-repair)[Ductless Mini-Splits](/services/ductless-mini-splits) [View All →](/services) Services [Smart Thermostats](/services/thermostats-controls)[Indoor Air Quality](/services/indoor-air-quality)[Ductwork](/services/duct-work)[HVAC Maintenance](/services/hvac-maintenance-tune-ups) [View All →](/services) [Maintenance Plans](/maintenance-plans) [Blog](/blog) More [Service Areas](/service-areas)[Financing](/financing)[Rebates](/rebates)[Reviews](/reviews)[About Us](/about)[Careers](/careers)[Contact](/contact) [View All →](/services/ac-installation) [(508) 715-9580](tel:5087159580)Book Online ![AC Installation & Replacement service by Fong & Sullivan in North Attleborough, MA](/assets/lg-smart-inverter-unit-DUrsgrM_.png) # AC Installation & Replacement Ready for a new air conditioning system?
